Overview
Most utility side-by-sides offer a combination of workhorse durability and simple operation, and the 2018 Kubota RTV-XG850 Sidekick fits that mold well. Designed primarily for light to moderate tasks around farms, ranches, or large properties, this machine emphasizes reliability and ease of use for those who need a dependable tool rather than a high-performance sport vehicle. Its no-frills design and practical features make it ideal for owners who prioritize functionality and low maintenance over flashy features or extreme off-road capability.
The RTV-XG850 is built around an 851cc inline liquid-cooled engine with a carburetor that delivers steady, predictable power for hauling, towing, or general utility tasks. It comes with a continuously variable transmission and a simple selectable drive system offering 4X2 or 4X4 modes, giving users control over grip and traction depending on terrain. Its suspension setup includes independent double A-arm front suspension with 9 inches of travel and rear independent suspension with 8.5 inches, providing enough cushion for rougher surfaces while maintaining stability.
This model’s overall character is rooted in its straightforwardness and practical design. It features hydraulic disc brakes on both front and rear wheels for reliable stopping power, and it sports tires that measure 25 inches in diameter, suitable for a variety of terrains. Built with dimensions that favor stability and ease of access, the Sidekick weighs around 1,761 pounds and boasts a generous 8.6-gallon fuel capacity, supporting long workdays without frequent refueling. Its notable position within the segment is its focus on durability and user-friendly operation, appealing to those seeking a dependable machine for everyday utility tasks rather than extreme off-road adventures or sport riding.”
Performance & Powertrain
Pull up the throttle and the 2018 Kubota RTV-XG850 Sidekick delivers a reliable 851cc inline four-cylinder engine that balances power with efficiency. This liquid-cooled engine provides enough torque for a variety of tasks, whether you’re hauling loads across farmland or navigating rough job sites. The carburetor fuel system keeps things simple, offering easy maintenance and consistent fuel delivery in typical utility applications.
In practice, this engine’s power output feels steady rather than aggressive, making it suitable for work that demands moderate acceleration and consistent speed. The 851cc displacement surpasses many competitors in the utility side-by-sides segment, giving it an edge in tasks requiring a bit more muscle without sacrificing fuel economy. The engine’s design emphasizes durability and ease of repair, which is critical for daily work around farms, construction sites, or large recreational areas.
The drivetrain features a continuously variable transmission that smoothly adjusts the drive ratio, eliminating the need for manual gear changes. This setup pairs well with the selectable 4X2 or 4X4 drive system, allowing users to adapt to changing terrain conditions quickly. The CVT provides a seamless power transfer that helps maintain momentum on uneven ground, while the selectable drive modes give the operator control over power delivery when navigating challenging slopes or loose surfaces.
Suspension & Handling
Working a full day on challenging terrain puts the suspension system of this machine to the test. The front independent double A-arm suspension offers 9 inches of travel, which helps absorb bumps and uneven surfaces encountered on trail rides or rough work sites. This travel amount provides a good balance for riding over rocky paths, loose dirt, or uneven terrain, allowing the machine to stay more comfortable and maintain stability without sacrificing responsiveness.
The rear suspension features an independent setup with 8.5 inches of travel, complementing the front end to improve ride quality in diverse conditions. This setup helps manage impacts from larger obstacles, making it more suitable for extended use on rough trails or work environments where stability and comfort matter. While not as long as some specialized off-road models, the travel figures are enough to keep the machine composed on most off-road surfaces without feeling overly soft or sluggish.
Braking is handled by hydraulic disc brakes on both the front and rear. This choice provides strong stopping power and heat dissipation, which is essential when descending steep slopes or hauling loads across rugged terrain. The hydraulic system allows for precise control and consistent performance during demanding conditions. The tires, sized at 25 x 10 – 12 for both front and rear, feature a blocky tread pattern designed to grip on loose dirt, gravel, and trail surfaces. They strike a good balance between grip and durability, though they may not excel as much on very slick or muddy terrain where more aggressive tread patterns are preferred.
Dimensions & Ergonomics
Most utility side-by-sides in the $13,000 range offer a size that balances maneuverability with stability, and the Kubota RTV-XG850 fits that mold well. Measuring just under 10 feet long at 9.75 inches and 10 inches wide, it can fit in most standard truck beds, making transportation easier for farm or worksite setups. Its 79.5-inch height keeps it accessible for a range of drivers without feeling overly tall or cramped. The wheelbase extends to 80.5 inches, providing a stable platform that resists tipping during uneven terrain or when carrying a load.
The ground clearance of 9.8 inches ensures it can handle rough terrain without scraping the undercarriage or getting stuck easily, which is critical for utility work or off-road pursuits. Its dry weight of 1,761 pounds strikes a balance between durability and manageable towing or loading. The seat height, in relation to these dimensions, tends to suit riders of varying heights, with enough space to accommodate both shorter and taller users comfortably. When seated, the ergonomic layout should promote a natural riding position, minimizing fatigue during long shifts or extended trail rides.
Additional considerations include its 8.6-gallon fuel capacity, offering a decent range for work or recreational use without frequent refueling stops. While cargo capacity isn’t specified here, the overall size and stable footprint suggest it can handle moderate loads, and the ergonomics are designed for comfort during extended use. The dimensions and rider fit make this machine suitable for users requiring a stable, easy-to-maneuver utility vehicle that fits well in a variety of practical environments.

These added touches can make a noticeable difference during extended use or tough jobs, providing real value for anyone needing a reliable workhorse for farms, construction sites, or outdoor projects.
Pricing & Value
If you’re planning to handle general utility tasks or farm work, you’ll want to know whether the 2018 Kubota RTV-XG850 Sidekick offers enough value for its $13,651 price tag. This machine is positioned as a mid-range option in Kubota’s lineup, sitting above entry-level models but below higher-spec models with more premium features or larger engines.
- Base price of $13,651 targets buyers seeking a reliable workhorse without paying for unnecessary luxury features
- Compared to competitors in the same class, it tends to hold its value well due to Kubota’s reputation for durability and strong resale
- Higher trims or optional accessories can push the price upward, but they often add only marginal improvements in function relative to cost
- Entry-level models undercut this price point by a few thousand dollars but typically sacrifice payload capacity, comfort, or fuel efficiency
This model offers a good balance of price and performance for those who need dependable utility rather than high-end features or sport-specific upgrades. Its place in Kubota’s lineup makes it an attractive choice for small farms, ranches, or work sites where durability is more critical than creature comforts. For buyers considering whether this machine justifies the cost, it delivers worthwhile value through its proven reputation, simple design, and resale strength, making it a fair deal for the needs it covers.
Final Thoughts
Anyone running maintenance tasks around a farm or construction site will appreciate the simplicity and durability of the Kubota RTV-XG850 Sidekick. Its no-frills design emphasizes reliability and ease of use, making it a strong choice for those who need a utility vehicle that can handle tough, regular work without fuss.
The defining feature of the RTV-XG850 is its durable construction and simple mechanics, which prioritize long-term dependability over fancy features.

If you’re a property owner or contractor seeking a work-ready vehicle that can tow, haul, and carry loads reliably day after day, this model fits the bill.
