John Deere S170 v Twin Riding Lawn Mower

The John Deere S170 and the John Deere S170 V-Twin are both riding lawn mowers designed for residential use, but they have some differences, particularly in their engine configurations:

  1. Engine:
    • The John Deere S170 typically features a single-cylinder engine.
    • The John Deere S170 V-Twin, as the name suggests, is equipped with a V-Twin engine configuration, which typically offers smoother operation and potentially more power compared to a single-cylinder engine.
  2. Performance:
    • Due to the V-Twin engine’s design, the S170 V-Twin may offer slightly better performance and smoother power delivery, particularly when tackling tougher mowing conditions or larger areas.
    • The standard S170, while still capable, may have slightly different performance characteristics compared to the V-Twin version.
  3. Price:
    • The S170 V-Twin may have a higher price point compared to the standard S170 due to the upgraded engine configuration.
  4. Maintenance:
    • While both mowers require regular maintenance, such as oil changes, air filter replacements, and blade sharpening, the V-Twin engine may have additional maintenance requirements due to its more complex design.
  5. User Experience:
    • Some users may prefer the smoother operation and potentially increased power of the V-Twin engine, while others may find the standard S170 to be sufficient for their needs and budget.

John Deere S170 Oil Change,Oil Filter, Oil Type

Oil Change:

  • The S170 features the John Deere Easy Change™ 30-second oil change system.
  • This system allows you to change the oil by simply twisting on a new oil-filled filter, without needing to drain the oil from the engine.
  • Changing the filter removes the captured contaminants and replaces about 0.8 qt (0.76 L) of engine oil.

Oil Filter:

  • The specific part number for the oil filter is AUC12916 (for USA, Canada, and Mexico), AUC13184 (for South America), or AUC14214 (for Europe).

Oil Type:

  • The recommended engine oil is John Deere Turf-Gard™ 10W-30, with a capacity of 2.6 L (2.8 qt).

The S170 uses the innovative John Deere Easy Change oil system, which greatly simplifies the oil change process.

John Deere S170 Mulching Blades

  1. Blade Design: Mulching blades, also known as 3-in-1 blades, are specifically designed with a unique shape and cutting edges to finely chop grass clippings into small pieces. These small clippings then fall back onto the lawn, where they decompose quickly, returning valuable nutrients to the soil.
  2. Airflow: Mulching blades feature a curved design and sometimes have extra cutting surfaces along the edges. This design creates airflow patterns that keep the clippings suspended for longer, allowing for more thorough mulching.
  3. Mulching Kit Compatibility: To use mulching blades effectively, you may need a mulching kit, which typically includes a mulching plug or cover for the mower deck. This kit helps create the proper airflow and containment for mulching operations.
  4. Benefits: Mulching blades offer several benefits, including promoting a healthier lawn by returning nutrients to the soil, reducing the need for fertilizers, and creating a neat and uniform appearance without the need for bagging clippings.
  5. Maintenance: Like standard blades, mulching blades require regular maintenance, including sharpening to ensure optimal performance. Dull blades can result in poor mulching efficiency and leave behind clumps of grass.
  6. Compatibility: When purchasing mulching blades for your John Deere S170, ensure they are compatible with your specific mower model and cutting deck size (usually 42 inches). Genuine OEM (Original Equipment Manufacturer) blades are recommended for the best fit and performance.
