John Deere G Tractor Repair Guide: Parts, Diagrams, Manuals

The John Deere G was a large two-cylinder general-purpose row-crop tractor built for farm work rather than modern suburban lawn care, so this guide is best suited to hobby farmers, acreage owners, restorers, and DIY owners who maintain vintage equipment in the USA and Canada. The article covers model overview, symptom-first troubleshooting, parts planning, manuals and diagrams, maintenance points, and an expanded FAQ in a practical format ready for publication.

John Deere G tractor overview

The John Deere G is identified in period documentation as a “General Purpose Tractor,” and the original operator information centers on starting, operating, adjusting, lubricating, and repairing the machine rather than on mower-deck or lawn-tractor use. In practical terms, that places the John Deere G in the classic letter-series Deere lineup for heavier utility, drawbar, belt, and PTO work on small farms, collections, and restoration properties.

For owners today, the big value of a John Deere G tractor repair guide is knowing where routine upkeep ends and where restoration-level mechanical work begins. Basic service such as fluids, ignition tune-up parts, air-cleaner attention, cooling-system checks, and brake or clutch inspection are realistic DIY tasks, while internal engine, differential, and timing work usually needs more experience and careful reference to manuals and parts diagrams.

General overview of the John Deere G tractor

The factory manual shows the John Deere G as a simple but substantial tractor built around several core systems: fuel and carburetion, ignition and magneto, cooling, lubrication, clutch and transmission, brakes, steering, power shaft, and power lift. The repair sections in the manual specifically cover carburetor adjustment, fuel system work, governor service, pistons and rings, main bearings, clutch, differential brakes, steering gear, rear axle bearings, power shaft, and drawbar adjustment.

That matters because most modern owner complaints on a John Deere G tractor fall into a few predictable groups: hard starting, weak running, overheating, oil leaks, clutch or brake issues, steering looseness, drivetrain noise, and poor power under load. A symptom-first workflow helps prevent owners from buying parts too early when the real issue may be adjustment, lubrication, stale fuel, weak spark, or a deeper engine problem.

Key systems on the John Deere G tractor

Engine and fuel system: tank, sediment path, carburetor, governor, pistons, rings, and tappets are central to starting and pulling power.
Ignition system: the manual includes ignition and magneto service, including timing procedures, so spark quality is a major diagnostic area.
Cooling and lubrication: the operator literature emphasizes water, crankcase oil, transmission oil, breather condition, and scheduled lubrication points.
Drive system: clutch, transmission, differential, rear axles, brakes, and power shaft all affect motion and usable field performance.
Chassis controls: steering gear, drawbar settings, and power lift adjustments matter on working tractors and restorations alike.

Common service parts owners look for

Several consumable and service items are directly referenced in the available operator material or commonly tied to John Deere G upkeep: oil filter element AA2092R, spark plugs, ignition points/condensers by magneto specification, carburetor kits, gaskets, brake facings, fluids, and tune-up parts. Owners also commonly look for manuals, gasket sets, piston rings, clutch parts, radiator and cooling-system items, and steering or brake components when bringing an older John Deere G tractor back into dependable use.

Troubleshooting a John Deere G tractor by symptom

The best way to diagnose an old John Deere G tractor is to begin with what the owner actually sees: it will not start, it starts but runs badly, it overheats, it leaks, it slips, it grinds, or it does not steer or brake properly. The factory manual itself is organized around operating checks, care, and then adjustment and repair operations, which supports a symptom-first approach before any teardown begins.

Main symptom categories for this model include:

Starting issues and weak ignition.
Running problems, surging, poor power, or carburetor-related performance faults.
Overheating and cooling-system concerns.
Oil leaks, crankcase or lubrication neglect, and breather-related mess.
Clutch, transmission, differential, and brake problems.
Steering looseness, vibration, and unusual mechanical noise.

John Deere G tractor emergency repair needs

Some faults on a John Deere G should be handled immediately because they affect safety or can rapidly damage expensive components. The most urgent examples are fuel leaks, severe overheating, no brakes, heavy drivetrain noise, clutch failure, and any sign of internal engine lubrication trouble.

Starting issues on the John Deere G tractor

Hard starting usually shows up as repeated crank attempts, weak firing, backfiring, or an engine that only runs briefly. On an older tractor, that matters because repeated starting attempts can flood the engine, drain the battery if electric-start equipped, and mask the real cause.

Common causes:

Stale or contaminated fuel.
Carburetor adjustment problems.
Weak magneto or ignition timing issues.
Fouled or worn spark plugs.
Low compression from valve or ring wear.

Basic owner checklist:

Confirm clean fuel and proper fuel flow to the carburetor.
Inspect plug condition and verify strong spark.
Check visible wiring, switch condition, and ignition timing basics if equipped accordingly.
Review carburetor settings and air-path cleanliness before replacing major parts.
Move to compression and valve checks if spark and fuel are both present but starting remains poor.

John Deere G tractor running and power problems

A John Deere G tractor that starts but runs rough, surges, smokes, or lacks pulling power often points to carburetor, governor, ignition, valve, or internal engine wear issues. These problems matter because continued operation under load can overheat the engine, foul plugs, and accelerate wear.

Common causes:

Carburetor misadjustment or internal contamination.
Governor linkage or adjustment issues.
Incorrect ignition timing.
Restricted air intake or breather issues.
Piston ring, valve, or bearing wear.

Basic owner checklist:

Run through fuel, spark, and air checks before assuming engine damage.
Verify throttle and governor movement is smooth and correctly linked.
Inspect plugs for rich, lean, or oil-fouled clues.
Adjust only to published settings and record any changes.
Stop and test compression if the tractor still lacks power after tune-up basics.

Vibration and noise on the John Deere G tractor

Unusual noise can come from the clutch, pulley area, steering components, axle bearings, brakes, or deeper engine internals. Owners should treat any sudden knock, grind, or heavy rumble as urgent because old components can fail quickly once clearances worsen.

Common causes:

Loose hardware or worn mounted parts.
Clutch or pulley-bearing issues.
Rear axle or differential bearing wear.
Brake drag or damaged brake components.
Internal engine wear.

Basic owner checklist:

Isolate whether the noise changes with engine speed, ground speed, clutch use, or PTO use.
Inspect accessible rotating parts and shields before moving the tractor again.
Check wheel and axle play safely with the tractor secured.
Stop operation if the noise is heavy, metallic, or rising quickly.
Use the parts catalog and service references before disassembly.

Overheating and leaks on the John Deere G tractor

Overheating on a John Deere G often presents as boiling, steam, coolant loss, power fade, or hot-running complaints in work conditions. Oil and fuel leaks are equally important because they raise fire risk and can starve major components of lubrication.

Common causes:

Low coolant or poor cooling-system maintenance.
Restricted airflow or dirty external surfaces.
Incorrect oil level or neglected oil changes.
Gasket or seal failure.
Overloading the tractor.

Basic owner checklist:

Let the tractor cool fully before opening any cooling component.
Check coolant and oil levels against the manual’s guidance.
Look for active drips around filter housing, drain points, gaskets, and lines.
Confirm the tractor is not being worked beyond its condition and tune state.
Repair leaks before longer operating sessions.

John Deere G tractor transmission, clutch, and brake problems

Difficulty moving off, clutch slippage, grinding, weak braking, or pulling to one side usually points owners toward the clutch, transmission, differential brakes, or rear axle areas. These are important safety faults, especially on slopes, road movements, or when towing implements.

Common causes:

Clutch wear or maladjustment.
Brake wear or incorrect brake setup.
Differential or axle-bearing problems.
Incorrect transmission lubrication.
Internal wear after long storage or hard use.

Basic owner checklist:

Check fluid condition and level first.
Test clutch engagement and brake response in a controlled area.
Inspect linkage free play and visible wear points.
Stop using the tractor if gears grind heavily or braking is unsafe.
Move to manual-guided adjustment before ordering internal parts.

DIY or dealer repair guide for the John Deere G tractor

The line on a John Deere G tractor is usually simple: maintenance, tune-up work, light adjustments, and external bolt-on service are realistic DIY jobs, but internal engine, clutch, transmission, differential, and precision timing work are better handled by experienced restorers, vintage tractor mechanics, or a Deere-friendly specialist with the right manuals.

Good DIY jobs

Engine oil and oil-filter service using the correct element reference.
Spark plug inspection and replacement.
Fuel-path cleaning and sediment checks.
Carburetor external adjustment to published settings.
Cooling-system checks and routine lubrication.
Brake and clutch inspection, but not major internal rebuilding.

Advanced DIY or dealer jobs

Magneto timing and ignition rebuild work.
Valve timing, tappet adjustment, and compression-related diagnosis.
Clutch teardown and pulley-bearing service.
Differential, rear axle-bearing, and transmission internal repairs.
Main-bearing, piston, or ring replacement.

Skill level guide

Beginner: fluids, plugs, external lubrication, visual checks, and basic fuel-system housekeeping.
Intermediate: carburetor tuning, brake adjustment, clutch linkage checks, and cooling-system service.
Advanced: timing, compression work, internal engine repair, clutch rebuilds, and differential service.

Parts for the John Deere G tractor: what you need before ordering

Before ordering anything for a John Deere G tractor, gather the full model name, tractor serial number, engine details if relevant to replacement ignition or internal parts, and any notes about whether the tractor is an earlier or later configuration. The factory literature explicitly tells owners to always give the tractor serial number when ordering repairs, which is especially important on vintage Deere machines where running changes matter.

For online ordering, also confirm whether you are buying a true OEM-equivalent service part, a reproduction restoration part, or a generic tune-up part that cross-references only by dimensions or specification. That extra check helps avoid common mistakes with old tractors, where a listing may fit only a certain serial range or a styled versus unstyled variation.

OEM vs aftermarket guidance is straightforward on a John Deere G tractor: use OEM or high-quality exact-spec replacements for safety-sensitive, fit-sensitive, and hard-to-replace items such as ignition components, brake materials, clutch-related parts, and internal engine parts. Aftermarket can be acceptable for common consumables or restoration items when the supplier clearly cross-references the tractor model, serial range, and subsystem involved.

John Deere G tractor parts diagrams and manuals

For this model, the most useful references are the operator’s manual, the parts catalog, Deere’s manuals portal, and a reputable model-specific parts supplier page. Each source solves a different problem, so owners should use them together rather than relying on a single listing.

Official John Deere manuals hub: Deere’s manuals and quick-reference pages are the best starting point for locating official operator information and maintenance resources by equipment type or model.
John Deere Quick Reference Guides: useful for Deere’s maintenance-information ecosystem and for navigating to official owner support resources.
PC369 parts catalog references: useful for exploded views and part-number research for G-series variants.
Reputable tractor parts sites such as Steiner, AgKits, or Yesterday’s Tractors: useful for cross-checking reproduction and aftermarket availability after you confirm the correct part number.

Useful links:

How to locate John Deere G tractor serial and engine numbers

These numbers matter because vintage Deere parts often break by serial range, subsystem version, or ignition/carburetor specification rather than by model name alone. The original manual specifically stresses giving the serial number when ordering repair parts.

Start with the tractor identification tag or serial plate and clean the area gently so the numbers are readable.
Record the full tractor model exactly as shown, including any variant markings if present.
Check the engine and ignition unit for their own identification tags, especially when ordering plugs, points, condenser sets, or carburetor parts.
Compare what you find against the operator manual and the PC369 parts catalog reference before ordering.
Save a phone photo of each tag so you can reuse the information when buying parts online or at a dealer counter.

Buying John Deere G tractor parts online and in stores

The best buying strategy is to confirm the correct manual reference first, identify the exact subsystem involved, and then order by part number or by serial-range-correct application rather than by a broad marketplace title. That reduces the risk of buying parts that physically resemble the original but do not match your tractor’s production details.

Online: best for manuals, tune-up parts, gaskets, and restoration items once OEM or catalog numbers are confirmed.
Dealer counter: best for serial-specific items, technical cross-checks, and anything where updated Deere supersessions may matter.
Retail stores: acceptable for fluids, some spark plugs, batteries, and universal shop supplies if the packaging clearly matches the tractor’s spec.

Step-by-step John Deere G tractor fitting guide

The highest-value DIY jobs on a John Deere G tractor are the ones that improve starting, reliability, and safe operation without forcing a major teardown. The tasks below stay close to the service areas clearly supported by the operator information and common owner needs.

Replace the oil filter on a John Deere G tractor

This job helps protect engine life and is one of the most important baseline services on any newly acquired tractor.

Warm the engine if safe to do so, then park securely and shut it down.
Drain the crankcase and the oil-filter section using the proper drain points noted in the manual.
Remove the oil-filter cap and replace the element with AA2092R, keeping the wire rings in place as instructed.
Refit the cap, reinstall drain plugs, and refill to the oil level point, adding the extra quart noted for the filter supply.
Start briefly, check for leaks, then recheck level after shutdown.

Fit new spark plugs on the John Deere G tractor

Fresh plugs can improve starting, idle quality, and power under load when the old set is fouled or weak.

Clean around each plug before removal so debris does not enter the cylinder area.
Remove one plug wire at a time to avoid mixing leads.
Compare the removed plugs for oil fouling, carbon, or overheating clues before discarding them.
Install the correct replacement plugs for the tractor’s ignition setup and tighten to the plug maker’s guidance.
Reconnect leads firmly and test start the tractor.

Check and adjust the carburetor on a John Deere G tractor

This job addresses rough running, poor throttle response, and some hot-start complaints when fuel quality and spark are already confirmed.

Begin only after confirming clean fuel, sound ignition, and no obvious intake restriction.
Bring the engine to operating condition if possible and work from the published adjustment procedure in the manual.
Make small changes only, noting the original setting before adjustment.
Test idle quality, throttle pickup, and loaded response after each change.
Stop and rebuild or professionally inspect the carburetor if adjustment has little effect.

Inspect brake condition on the John Deere G tractor

Brake work matters for safe transport, parking, and field operation, especially on uneven ground.

Park on level ground, block wheels, and verify the tractor cannot roll.
Check pedal travel, side-to-side balance, and any sign of drag or weak engagement.
Inspect accessible linkage and hardware for looseness or visible wear.
If brake material is worn, use the recommended facings and special rivets referenced in the manual.
Test at low speed in an open area before returning the tractor to work.

Maintenance for the John Deere G tractor

Regular maintenance prevents a large share of John Deere G tractor complaints because this machine depends heavily on clean fuel, proper lubrication, sound cooling, and correct adjustment. The operator literature repeatedly emphasizes daily attention, tight hardware, proper oiling, and consistent care to reduce wear, power loss, repair cost, and premature replacement.

Focus areas:

Starting reliability: keep ignition components sound, plugs clean, and fuel fresh.
Engine life: change oil and filter on schedule and monitor breather and lubrication points.
Cooling protection: maintain proper water/coolant level and keep the tractor from running overheated.
Drive performance: watch clutch feel, brake balance, and transmission lubrication.
Safety and usability: correct steering play, fastener looseness, and fuel or oil leaks early.

John Deere G tractor maintenance schedule

The surviving operator information for the John Deere G emphasizes daily checks, lubrication-chart intervals, periodic oil service, transmission lubrication, air-cleaner care, cooling-system attention, and less frequent bearing repacking rather than the modern 25/50/200-hour lawn-tractor style schedule. For a WordPress article aimed at present-day owners, the best approach is to translate those official maintenance areas into a practical seasonal checklist without inventing unsupported interval claims.

Daily or before each use

Check engine oil level and top up if needed.
Check transmission oil as directed in the manual.
Check water/cooling level before work.
Inspect fuel supply and look for contamination or leakage.
Walk around the tractor for loose hardware, leaks, or obvious wear.

At lubrication-chart intervals

Grease all fittings listed in the lubrication chart.
Lubricate steering gear with transmission oil as specified.
Maintain tappet lubrication path and inspect for oil delivery issues.
Service auxiliary lubrication points shown by the manual.

Periodic oil-service interval

Drain engine oil when hot where practical.
Replace the oil-filter element with AA2092R.
Refill correctly, including the extra quantity needed for the filter housing.
Recheck for leaks after running.

Annual or long-interval tasks

Repack the front fan bearing at least once every two years.
Repack pulley bearings after two years of normal operation or whenever disassembled/overheated.
Inspect brake facings, linkage, and wheel-bearing or axle play.
Review cooling-system condition, breather condition, and storage readiness.

Seasonal checklist for the John Deere G tractor

Spring or return-to-service: change fluids if age is unknown, inspect ignition, clean fuel path, and check cooling before field work.
Mid-season: monitor hot-running behavior, brake performance, and clutch feel under load.
Fall or storage prep: clean the tractor, correct leaks, protect fuel and cooling systems, and store only after a final inspection.
Long storage: follow the manual’s storage guidance and avoid putting the tractor away dirty or with unresolved fuel issues.

Repair, upgrade, or replace a John Deere G tractor?

With a John Deere G tractor, the decision usually depends less on market value alone and more on originality goals, mechanical condition, intended workload, and whether the tractor is a working hobby machine or a restoration piece. Because the machine is simple, well documented, and supported by reproduction-parts sellers, many problems are repairable, but not every tractor is economical to rebuild from the crankshaft out.

Repair if

The tractor is complete and the problem is mainly tune-up, fuel, cooling, clutch, brake, or adjustment related.
Compression is usable and no catastrophic drivetrain damage is present.
You want to preserve an original machine with manageable parts needs.

Upgrade if

You need better reliability from ignition, wiring, or tires while keeping the tractor mostly original.
You use the tractor regularly and want higher confidence from quality replacement consumables.
You can improve usability without compromising safe operation or parts fit.

Replace if

The tractor has severe internal engine, transmission, or differential damage plus major missing parts.
The project cost exceeds the value or purpose of the machine for your property.
You need a modern mower or utility tractor rather than a vintage field tractor.

John Deere G tractor FAQ

1. Why will my John Deere G tractor not start?

The usual starting checks are fuel, spark, timing, and compression. Start with clean fuel flow and spark-plug condition, then move to ignition timing and carburetor settings before assuming internal engine damage.

2. Why does my John Deere G tractor start and then die?

That pattern often points to restricted fuel flow, carburetor contamination, or an ignition issue that worsens as the tractor runs. Check fuel delivery and basic carburetor adjustment first because they are common and easier to confirm than deep engine faults.

3. Why is my John Deere G tractor hard to start when hot?

Hot-start problems often come from rich running, weak spark, marginal timing, or fuel-system issues that appear after heat soak. A careful tune-up and carburetor review usually make more sense than replacing random parts.

4. Can bad spark plugs cause rough running on a John Deere G tractor?

Yes, fouled or worn plugs can weaken combustion and make the tractor idle poorly or miss under load. Plug color also gives clues about whether the engine is running rich, oiling, or overheating.

5. Why does my John Deere G tractor have weak power under load?

Weak power often ties back to carburetor adjustment, governor function, ignition timing, or compression loss. If tune-up work does not improve the tractor, compression and valve-related checks become more important.

6. Why is my John Deere G tractor surging?

Surging usually points to uneven fuel delivery, carburetor settings, governor issues, or an intake-side problem. Confirm clean fuel first, then look at adjustment rather than jumping straight to overhaul.

7. Why does my John Deere G tractor backfire?

Backfiring can result from ignition timing errors, poor mixture, or valve-related problems. The exact cause depends on whether the backfire is through intake, exhaust, or only during shutdown.

8. Why is my John Deere G tractor overheating?

Low cooling level, restricted airflow, neglected maintenance, or overloading are common reasons. Stop using the tractor until you correct the cause because repeated overheating can create much larger repair bills.

9. Is coolant loss normal on a John Deere G tractor?

No persistent coolant loss should be ignored on a working tractor. Check for leaks, poor sealing, and signs of overheating before longer use.

10. Why is my John Deere G tractor leaking oil?

Oil leaks commonly come from service points, seals, gaskets, and neglected crankcase service areas. Clean the tractor first so you can identify the true leak source instead of guessing from old residue.

11. What oil filter does a John Deere G tractor use?

The available operator-manual text references oil filter element AA2092R during crankcase service. Confirm fitment against your tractor’s exact configuration before ordering.

12. How often should I change oil on a John Deere G tractor?

Use the operator manual and lubrication guidance as the baseline because surviving documentation is the safest source for this vintage model. On newly purchased tractors with unknown history, an immediate oil and filter change is usually wise.

13. Why does my John Deere G tractor smoke?

Smoke can indicate over-rich running, oil consumption, or deeper wear in rings or valves. The color and timing of the smoke help narrow the fault before you disassemble anything.

14. Why is the clutch slipping on my John Deere G tractor?

A slipping clutch can come from wear, maladjustment, contamination, or heat damage. Do not keep working the tractor hard because extra slip increases the chance of larger clutch repairs.

15. Why are the brakes weak on my John Deere G tractor?

Weak brakes can result from worn facings, poor adjustment, damaged linkage, or drum-related issues. Because brake parts are safety-critical, use correct-spec replacements and test only at low speed first.

16. Can I replace John Deere G tractor brake facings myself?

It is possible for an experienced DIY owner, but the job needs careful assembly and correct materials. The manual notes that Deere dealers can supply the recommended facings and special rivets.

17. Why does my John Deere G tractor grind going into gear?

Grinding can point to clutch disengagement problems, internal wear, or incorrect operating technique. Check clutch action and linkage first before assuming the transmission needs major repair.

18. Why does my John Deere G tractor pull to one side when braking?

That usually means one side is adjusted differently or has more wear than the other. Brake balance issues should be corrected quickly because they affect safety and control.

19. Why is steering loose on my John Deere G tractor?

Steering looseness often comes from wear in the steering gear or related front-end components. Vintage tractors can tolerate some play, but excessive looseness should be fixed before road or implement use.

20. What causes vibration on a John Deere G tractor?

Vibration can come from loose hardware, clutch or pulley problems, axle-bearing wear, brake drag, or internal engine issues. The first clue is whether the vibration changes with engine speed or with ground travel.

21. Why is my John Deere G tractor making a knocking noise?

A knock can be minor external looseness or a serious internal engine problem. If the sound is heavy or rapidly worsening, shut the tractor down and inspect before operating again.

22. Why does the governor on my John Deere G tractor seem unresponsive?

The manual includes governor service because governor behavior is a known performance area on this tractor. Poor response can be linkage-related, adjustment-related, or part of a wider fuel-and-ignition problem.

23. Should I rebuild or replace the carburetor on a John Deere G tractor?

Rebuild first if the carburetor is complete and the body is sound. Replacement only makes more sense when the casting is damaged, major pieces are missing, or a correct rebuild will cost more than a quality substitute.

24. Can I use aftermarket parts on a John Deere G tractor?

Yes, but only after you verify the exact cross-reference and application. OEM or exact-spec parts are safer for fit-sensitive, ignition, brake, and internal engine jobs.

25. Where can I find John Deere G tractor parts diagrams?

The most useful starting points are the Deere manuals/support pages and the PC369 parts-catalog references from established tractor-parts suppliers. Use diagrams to confirm assemblies before ordering, especially on older tractors with variant changes.

26. Where can I find a John Deere G tractor operator’s manual?

John Deere’s manuals ecosystem is the official place to start, and reprint suppliers also list operator manuals for the model. Always match the manual to the tractor’s serial range when possible.

27. Why is the oil on my John Deere G tractor getting dirty quickly?

Old engines can darken oil quickly, but very rapid contamination can also point to neglected maintenance, sludge, or internal wear. Change the oil and filter, then monitor how quickly the condition returns.

28. Does the John Deere G tractor need regular grease service?

Yes, the operator manual specifically references a lubrication chart and multiple grease or oil service points across the tractor. Skipping lubrication is one of the fastest ways to create avoidable wear.

29. How often should fan and pulley bearings be repacked on a John Deere G tractor?

The available manual text says the front fan bearing should be repacked at least once every two years, and the pulley bearing should be repacked after two years of normal operation or whenever disassembled or overheated.

30. Why does my John Deere G tractor use more fuel than expected?

High fuel use can come from carburetor settings, heavy loading, poor ignition efficiency, or general engine wear. Tune-up basics should come before any major repair decision.

31. Can I still get John Deere G tractor manuals and service information online?

Yes, Deere maintains an online manuals and quick-reference pathway, and model-specific operator or parts-manual sources are also available through specialist suppliers. The key is to verify that the source matches your tractor and serial range.

32. What should I check first on a newly purchased John Deere G tractor?

Start with engine oil, oil filter, cooling level, fuel quality, spark plugs, lubrication points, and brake function. Those baseline checks reduce the chance of damaging the tractor before you know its true condition.

33. Is the John Deere G tractor a good DIY restoration candidate?

It can be, because the tractor is mechanically straightforward and manuals and parts references still circulate through specialist sources. The main limiting factors are completeness, internal condition, and how original you want the finished machine to be.

34. When should I stop DIY repair and call a specialist for my John Deere G tractor?

Step back when you find low compression, timing uncertainty you cannot confidently correct, internal drivetrain noise, unsafe brakes, or evidence of bearing damage. At that point, guesswork is usually more expensive than expert help.

35. Is a John Deere G tractor suitable for mowing large lawns?

Not in the same way as a modern Deere lawn tractor or riding mower. The John Deere G is a vintage general-purpose farm tractor, so it suits hobby farm and restoration use far better than routine suburban lawn care.
