Kubota RTV Cargo, Storage / Tool-Carrying Accessories Guide

Kubota RTV Cargo, Storage and Tool-Carrying Accessories Guide

Kubota RTV cargo accessories include lockable toolboxes, bed mats, liners, cargo clamps, bed extenders, storage organizers and equipment-carrying frames. Newer extended-bed models also have dedicated under-bed storage boxes, cargo lights and an in-bed winch. These products serve different purposes, and compatibility depends on the vehicle, cargo-bed design and other accessories already installed.kubotausa+1

A toolbox can help organize smaller tools, while an extender changes how the bed accommodates suitable loads. A bed mat protects the floor, and a cargo rack provides another mounting or carrying arrangement. None of these should be treated as an automatic increase in the vehicle’s permitted payload.

This guide covers documented current and legacy Kubota RTV storage equipment, selected part references, mounting requirements and practical compatibility checks.

The focus is North American manufacturer information. Archived part numbers establish documented applications, not guaranteed availability. Confirm the complete vehicle designation, serial information, bed configuration and current installation instructions before ordering.

These categories are documented in Kubota’s accessory brochures, current packages and LONG BED information. They are not universally available for every model.kubotausa+2

Cargo Volume, Bed Load and Payload Are Different

Before selecting storage equipment, distinguish the space available from the weight permitted.

Term	What it describes
Cargo-box volume	The space inside the cargo area
Cargo-bed load	The permitted weight in the bed for the specified configuration
Vehicle payload	The vehicle’s applicable total load allowance
Accessory weight	The weight added by boxes, racks, mounting equipment and other accessories
Accessory rating	A limit assigned to a particular component or system

A bed extender can change the shape of the usable cargo area without changing the vehicle’s permitted load. Similarly, a larger toolbox creates enclosed storage but occupies space and adds weight.

Kubota’s LONG BED product page describes a six-foot cargo platform and separately lists its bed-lift/load figure. Its cargo winch has another, separate rating. Those figures must not be combined into one general capacity claim.kubotausa

Use the operator’s manual and accessory instructions for the exact vehicle and configuration.

Kubota Deluxe RTV Cargo Box

The Deluxe RTV Cargo Box, reference 77700-08760, is one of Kubota’s documented enclosed storage options.

The manufacturer lists 4.5 cu. ft. of internal cargo capacity, polyethylene construction, lockable latches and sliding removable tool trays. Covers provide access from either side.kubotausa

Toolbox Features and Requirements

Item	Manufacturer information
Accessory name	Deluxe RTV Cargo Box / Cargo Bed Tool Box
Reference	77700-08760
Listed storage volume	4.5 cu. ft.
Construction	Polyethylene
Security feature	Lockable latches
Internal organization	Sliding and removable tool trays
Access	Covers accessible from either side
Main mounting requirement	Two pairs of K7811-99560 cargo clamps and V0838 mounting kit
Additional requirement with V0830 bed mat	Two additional V0838 mounting kits

The mounting requirements are explicit in Kubota’s product listing.kubotausa

Documented Model Applications

Kubota’s archived brochure lists the cargo box in the Sidekick section and for the numeric X900, X1120, X1100 and X1140 applications. Current Sidekick Frontier package information also includes the box.kubotausa+1

These references are useful starting points, not approval for every newer cargo-bed design or production variant.

Is the Cargo Box Waterproof?

Kubota describes the construction as resisting corrosion, water and dust. That is not the same as a published waterproof or immersion rating.kubotausa

Do not promise that every stored item will remain dry in every operating condition. Follow the product instructions and provide suitable protection for moisture-sensitive equipment.

Cargo Clamps and Toolbox Mounting Kits

Mounting components are part of the installation, not optional extras.

Cargo Mounting Equipment

Accessory	Reference	Documented function	Important detail
Cargo-bed accessory clamp	K7811-99560	Drill-less mounting with interchangeable rubber inserts	Sold as a pair
Plastic Cargo Box Mounting Kit	77700-V0838	Supports the specified Deluxe Cargo Box installation	Required with the box
Additional mounting kits	77700-V0838	Supports the documented box installation over V0830 mat	Two additional kits specified

Kubota’s clamp listing identifies the pair packaging, while the toolbox listing specifies two pairs for the box installation. That means the stated requirement is four individual clamps—not two.kubotausa+1

Do not substitute a visually similar clamp or improvise a mounting arrangement without approval.

Why the Bed Mat Changes the Installation

Kubota specifically requires two additional V0838 mounting kits when the Deluxe Cargo Box is installed with the V0830 rubber cargo-bed mat.kubotausa

This is a useful example of accessory interaction: a box that fits the vehicle may still need different supporting hardware when another accessory is fitted.

Kubota RTV Bed Mats and Plastic Liners

Bed protection is available in several forms.

Cargo-Bed Protection Directory

Accessory	Reference	Documented application	Main purpose
Polyurethane cargo-box pad	K7211-99200 / V4352	RTV400	Model-specific cargo pad
Polyurethane cargo-box pad	K7311-99200 / V4351	RTV500	Different reference from RTV400
Rubber cargo-bed mat	77700-V0830	Sidekick and specified numeric RTV-X applications	Surface protection and reduced cargo movement
Plastic bed liner	K7591-99580 / V5229	Numeric X900, X1120 and X1100	Protection against bed dents and damage

These references come from Kubota’s archived accessory brochure. The V0830 and liner applications should not be extended to an RTV-X1140, ProKonvert bed or LONG BED without confirmation.cdnmedia.endeavorsuite

A Mat Does Not Replace Load Restraint

Kubota describes the rubber mat as helping prevent objects sliding around the bed. That feature does not replace the need to secure a load appropriately.cdnmedia.endeavorsuite

Use the vehicle’s approved attachment points and suitable restraint equipment. Do not assume that a toolbox, mat or liner makes loose tools secure.

Cargo-Bed Extenders, Dividers and Rails

These accessories change the bed arrangement, but they are not all compatible with one another.

Extender and Rail Comparison

Accessory	Reference	Documented function	Compatibility restriction
Cargo-bed extender	K7811-99570	Drill-less design that can be positioned along the bed	Confirm the vehicle and mounting application
Cargo-bed rail / cargo extender	K7811-99590	Left-and-right rail arrangement	Explicitly incompatible with 77700-08760 Deluxe Cargo Box
LONG BED extended tailgate	K7921-99590	Reaches the ground when the bed is fully raised	Dedicated extended-bed application

The K7811-99570 extender can be positioned to extend or divide the cargo area. The K7811-99590 rails are a different accessory and are sold as a left-and-right pair.kubotausa+2

Do Not Confuse the Similar Part Numbers

K7811-99590 and K7921-99590 are different references:

K7811-99590 identifies the documented cargo-rail/extender accessory.
K7921-99590 identifies the LONG BED extended tailgate.kubotausa+1

Copy the complete number when checking a dealer listing.

Cargo Rails and Toolbox Compatibility

Kubota explicitly states that K7811-99590 is incompatible with the Deluxe RTV Cargo Box 77700-08760.kubotausa

Do not assume that every accessory shown in the same brochure can be installed simultaneously.

Rapid Access Cargo Frame and Basket

Kubota’s older numeric RTV-X accessory literature includes the Rapid Access Cargo, or RAC, system.

Documented RAC Equipment

Accessory	Reference	Source-listed applications	Manufacturer description
Full RAC Frame System	77700-V5012	X900, X1120 and X1100	Powder-coated steel frame with exterior-mounted risers
Extender Basket	77700-V5015	X900, X1120 and X1100	Basket for the compatible RAC arrangement

The brochure states that the frame can work with or without a cab and weighs approximately 85 lb.cdnmedia.endeavorsuite

Why Rack Weight Matters

An 85-lb. frame is part of the vehicle’s installed equipment. It should be accounted for when planning the overall load rather than treated as weight-free storage.cdnmedia.endeavorsuite

Confirm the permitted rack load, mounting requirements and vehicle restrictions from the applicable instructions.

Do not transfer the old RAC application automatically to a ProKonvert cargo box, newer crew model or LONG BED.

Tool Holders and Rack Attachments

The archived brochure refers to compatible attachments, but that does not justify inventing a universal holder list or assigning fitment to every tool mount sold online.cdnmedia.endeavorsuite

For a chainsaw, trimmer, shovel or blower holder, obtain the attachment’s own application and mounting instructions.

Front and Underhood Storage

Rear cargo space is not the only documented storage location.

Front Storage Accessories

Accessory	Reference	Documented application	Main compatibility point
Front Accessory Box	K7311-99560 / V4335	RTV400/RTV500	Mounts under the hood
Rack Over Hood	77700-V0831	Sidekick accessory literature	Mounts to the approved front guard
Sidekick plastic bumper	K7811-99220	Separate accessory	Explicitly incompatible with the V0831 rack

Kubota describes the V0831 rack as removable without tools and able to pivot for access to components beneath the front hood.cdnmedia.endeavorsuite

Do not confuse K7311-99560, the smaller-RTV front storage box, with K7811-99560, the cargo-clamp pair. The similar numbers identify different products.kubotausa+1

Preserve Service Access

A storage accessory should be installed so the approved service access and operating clearances remain available.

For the documented Sidekick rack, its pivoting arrangement is part of the design. Do not replace that function with an improvised fixed installation.cdnmedia.endeavorsuite

Tool Bags, Organizers and Hanging Accessories

Smaller items can organize equipment without a full bed-mounted toolbox.

Tool-Carrying Accessory Directory

Accessory	Reference	Documented features	Appropriate interpretation
ROPS Storage Organizer	77700-V4384	Nine pockets and padded construction	Smaller-RTV organizer, not a heavy-load rack
Work Gear Bag	77700-10694	Ballistic nylon, straps and rack-compatible buckles	Secure it using the intended arrangement
Reusable tool tie	77700-10782	32-inch loopable tie for long-handled tools and other items	Do not assume a rated transport-restraint capacity
Dual carabiner	77700-10783	Ten-inch hanging accessory	Not evidence of a lifting or recovery rating
Sidekick door storage	Included in documented VP0810 doors	Pocket and bottle holder	Depends on the compatible door assembly

Kubota’s Work Gear Bag is listed at 18 inches long, four inches wide and 11 inches tall. The product description identifies a strap kit and buckles for specified rack arrangements.kubotausa+1

Tool Organization Is Not the Same as Secure Transport

An organizer, hanging tie or carabiner can help position equipment. Its presence does not establish that the tool is secured for every travel condition.

Use the attachment instructions and suitable restraints, and keep equipment clear of controls, seating and required access.

Ratchet Straps and Cargo Nets

Kubota lists dedicated load-restraint accessories separately from storage equipment.

Load-Restraint References

Accessory	Reference	Documented size or description	Main check
ShockStrap load-absorbing ratchet strap	77700-10680	Nine-foot by two-inch reference in current product information	Read the actual label and instructions
ShockStrap load-absorbing ratchet strap	77700-10681	Eighteen-foot by two-inch reference	Match restraint and anchor requirements
Cargo Net	77700-08978	34 × 34 inches, stretching to 60 × 60 inches	Confirm suitability for the actual load

Kubota describes the cargo net with adjustable plastic hooks and weather-resistant construction. Its broad fit description does not establish a universal securement method for every heavy or awkward item.kubotausa

Do Not Substitute Break Strength for Working Load

Use the actual restraint label and instructions when selecting equipment. Do not invent a working-load limit from a product’s size or a general marketing description.

Similarly, a tow strap should not automatically be used as a cargo tie-down, and an accessory clamp should not be treated as a rated load anchor without supporting instructions.

ProKonvert Cargo Beds and Load Separation

ProKonvert is a cargo-bed system, not a generic accessory that can be assumed to bolt onto every older RTV.

Kubota’s RTV-X1130 launch information describes side and tailgate conversion without tools, flatbed configuration and material separation using dividers. The current LONG BED page likewise describes removable or folding side panels and built-in slots for load separation.kubotausa+1

ProKonvert Features Relevant to Storage Planning

Feature	Practical role	Compatibility consideration
Folding or removable side panels	Side loading and flatbed conversion	Accessories must permit the approved panel movement
Tailgate configuration	Rear access	Check interaction with extenders and installed equipment
Divider arrangement	Separates suitable materials	Follow the specified divider requirements
Dedicated cargo accessories	Loading, lighting and storage	Use the correct bed-specific application

Do not assume a liner, RAC frame or toolbox mount intended for an older fixed-sided bed fits the ProKonvert arrangement.

RTV-X1130 and LONG BED Cargo Accessories

The extended-bed models have dedicated equipment that deserves its own application check.

Kubota introduced the RTV-X1130 with an in-bed winch, tailgate extender, cargo lighting and under-bed storage options. Current LONG BED information identifies corresponding accessory categories with specific references.kubotausa+1

LONG BED Accessory Table

Accessory	Reference	Manufacturer information	Important distinction
Extended Tailgate	K7921-99590	Allows the tailgate to rest against the ground with the bed fully raised; folds away when not used	Not the older Sidekick cargo rail
Cargo Winch	K7921-99580	Wireless controller and published 750-lb. capacity	In-bed cargo equipment, not a universal recovery winch
Cargo Panel Light	K7921-99570	Two six-inch LED lights	Cargo-area lighting system
Under-Bed Storage Boxes	K7921-99560	Two lockable plastic boxes, one per side	Mounts beneath the cargo bed

These references come from Kubota’s current LONG BED product page.kubotausa

Under-Bed Storage Boxes

The K7921-99560 kit provides storage outside the main cargo-box space.

Kubota lists two lockable plastic boxes, one for each side beneath the bed.kubotausa

Confirm the applicable vehicle and installation clearances. A storage box designed around the extended-bed chassis should not be assigned to another RTV simply because there appears to be space beneath its bed.

Cargo Winch vs Recovery Winch

The K7921-99580 is described as a cargo winch with a 750-lb. capacity.kubotausa

That rating does not increase the vehicle’s payload and should not be interpreted as approval for overhead lifting or vehicle recovery. Use the accessory’s intended application and operating instructions.

RTV-X1130 vs LONG BED Fitment

Both names appear in Kubota’s extended-bed information, but shared accessory categories do not establish universal parts interchangeability.

Use the original vehicle designation and current catalogue application before ordering a replacement box, winch, panel or mounting component.

Choosing a Cargo Setup for Your Work

Match the equipment to the task and confirm the complete installation.

Main requirement	Accessories to investigate	First question to resolve
Organizing smaller tools	Deluxe Cargo Box, gear bag or under-bed boxes	Which equipment fits the actual vehicle?
Protecting the bed floor	Mat, pad or liner	Is it compatible with other mounts?
Separating materials	Approved divider or extender arrangement	Does it fit the cargo-bed design?
Carrying long or bulky items	Approved extender, rails or LONG BED arrangement	What configuration and restraints are permitted?
Keeping the rear bed available	Underhood box, approved front rack or under-bed storage	Is the proposed location approved?
Rack-based organization	RAC frame and compatible attachments	Are the frame and attachment applications verified?
Loading awkward cargo	Approved in-bed winch and extended tailgate	Are the complete system and operating limits understood?

The options above reflect the manufacturer’s documented products. They are not a universal recommendation for every RTV.kubotausa+1

Cargo-Accessory Compatibility Checklist

Before ordering, confirm:

Full model and serial information.
Fixed-sided, convertible or ProKonvert bed.
Seating configuration where applicable.
Exact accessory reference.
Required clamps and mounting kits.
Compatibility with mats and liners.
Clearance for bed tipping and panel movement.
Access to servicing points.
Accessory weight and vehicle loading restrictions.
Required electrical equipment.
Approved load-restraint points.
Current instructions and parts availability.

Pay particular attention to explicit exclusions. The K7811-99590 rails conflict with the Deluxe Cargo Box, and the V0831 overhood rack conflicts with the documented Sidekick plastic bumper.kubotausa+1

Inspecting Used Cargo Accessories

A used accessory is most useful when its identity and completeness can be established.

Used item	What to verify
Toolbox	Latches, lids, trays, clamps and complete mounting kit
Mat or liner	Correct shape, fit and interaction with mounts
Extender	Complete brackets and correct application
Rack	Identification, undamaged mounting points and instructions
Under-bed boxes	Correct left/right components and mounting hardware
Cargo winch	Full kit, controller and applicable instructions
Straps or net	Condition, labels and suitability for continued use

Do not assume that drilling new holes is an acceptable way to adapt an incompatible box or rack.

A legacy catalogue listing also does not guarantee that missing hardware remains supplied. Confirm availability before buying an incomplete assembly.

Kubota RTV Cargo and Storage FAQs

Which toolbox is documented for Kubota RTV applications?

Kubota lists the Deluxe RTV Cargo Box 77700-08760 with 4.5 cu. ft. of storage, lockable latches and removable tool trays. Fitment and required hardware must be confirmed.kubotausa

How many cargo clamps does the Deluxe Cargo Box require?
