The Gator™ XUV Crossover Series Utility Vehicle has a precision-engineered drivetrain system that fully utilizes engine power, optimizing acceleration, hauling, towing, and hill-climbing capabilities. Power is transmitted from the engine through a continuously-variable clutch system to the transaxle.
Key elements of the drive system include:
The variable-speed drive consists of two clutches and a drive belt:
- Drive clutch is attached to the engine.
- Driven clutch is attached to the transaxle.
- The engine braking system utilizes a tight belt for operation, requiring an idler sleeve on the primary clutch for neutral. The secondary clutch is a build-on-shaft design that utilizes a cam to tune the acceleration and deceleration of the vehicle. The clutch will stay engaged, providing deceleration until approximately 5 km/h (3 mph).
- The continuously variable transmission (CVT) air intake draws in 50 percent more air versus previous designs to reduce heat and the amount of water ingestion into the CVT system. The system will reduce belt slippage and improve durability.
- A low- and high-speed forward gear offering:
- Low range is 0 km/h to 47 km/h (0 mph to 29 mph), XUV835
- Low range is 0 km/h to 24 km/h (0 mph to 15 mph), XUV865
- High range is 0 km/h to 72 km/h (0 mph to 45 mph), XUV835
- High range is 0 km/h to 51 km/h (0 mph to 32 mph), XUV865
- Ability to creep along slowly to maneuver in tight spaces
- Standard full-clutch enclosure with high speed fan provides longer belt and clutch life
- High-ratio clutches with three cam weights for maximum belt-clamp load in high torque conditions
NOTE: Delivery and torque to the ground depends on tire size, which is a function of nominal size and pressure.
How the variable-speed drive works:
- As engine speed increases, the spring-loaded drive clutch is closed by weights being forced out by centrifugal force.
- As the drive clutch closes, the belt rides up to the largest diameter of the drive clutch and forces open the driven clutch.
- With the belt running in the smallest diameter of the driven clutch, the speed being transferred to the transaxle is increased.
- The driven clutch is designed to sense varying loads (inclines, mud, etc.) and constantly adjusts drive speed upward or downward so that engine rpm remains optimal.

Operator interface features:
- On-demand true four-wheel drive (4WD) system with an auto-locking front differential and dash-mounted electronic rocker switch is best in class. When the rocker switch is in the on 4WD position, the front differential will automatically lock for extra traction when needed, but when the rocker switch is in the off two-wheel drive (2WD) position, the vehicle will remain in 2WD.
- Provides exceptional traction in challenging conditions
- Maintains turf-friendly operation in 2WD mode
- Illuminated for visibility in low-light condition
- Two-speed, fully-enclosed oil bath transaxle allows for superior pulling ability
- Cast-aluminum design is the most robust in the industry
- Helical forward and reverse gears are used for quiet operation
- Rear traction assist (differential lock) is built in and can be engaged on demand
- Allows locking the rear drive wheels together
- Provides increased traction in tough spots
NOTE: Differential design reduces scuffing of the turf during turns because it allows the inside wheels to turn slower than the outside wheels.
- Neutral start safety interlock for engine ignition system
- Large, sealed bearings are located inside the housing for better protection and durability
- Contains gear case for transferring power to the MFWD
- Splined shaft interfaces for maximum torque transfer and durability
- All drive gears machined from highest grade gear steel
- Protected by a skid plate
- Electronic design is auto-locking for ease of use
- Performs like a locking differential when engaged, but like an open differential when cornering
- Offers positive engagement of both front wheels in forward and reverse as a differential package
- Automatic engagement on the fly—no shift linkages required
- Protected by a skid plate and frame
Drive shaft features:
- Rear CV shaft diameter measures 27 mm (1.1 in.) and is designed for peak engine and braking torque
- Front CV shaft diameter measures 23 mm (0.91 in.) and is designed for peak engine torque
- Propshaft is designed for peak engine torque
- All CV shaft and propshaft joints are maintenance free and protected by exclusive thermoplastic elastomer (TPE) boots for durability
