  • Equipped with power steering

    This Gator™ XUV Crossover Utility Vehicle is equipped with power steering and a dual A-arm front suspension. These automotive-type systems exhibit excellent handling characteristics, as well as responsive steering and low steering effort:

    • Steel ball bearings secure the steering shaft and deliver smooth, responsive operation
    • Completely-sealed rack-and-pinion for long life
    • Low steering ratio (lock-to-lock) provides more responsive steering and less operator input
    • Shaft U-joints are phased for a smooth, uninterrupted motion of the steering wheel
    Electric power-assist steering systemElectric power-assist steering system
    #

    Electric power-assist steering (EPAS) system has advanced features:

    • Anti-kickback feature reduces the amount of steering unwinding when traversing difficult terrain.
    • The system is speed sensing and adjusts steering effort as the speed of the vehicle changes.
      • As speed increases, there is less steering assist for improved road feel.
      • As speed decreases, steering assist increases to give lower steering efforts for improved maneuverability.
    • A warning/functional light on the instrument panel provides self-diagnostics and a warning light in the situation of no assist.
    • Torque sensor measures steering wheel input so the on-board computer can provide the appropriate output for various driving situations.

    With the EPAS system, the operator maintains a direct, mechanical linkage from the steering wheel to the front wheels. The power-steering system interfaces mechanically with the steering system by being inserted between the steering wheel and the rack-and-pinion assembly.

     

    A differential torque sensor is integrated into the power steering assembly. The circuit board assembly is also integral with the power-steering assembly.

     

    Power steering does not reduce turning radius but significantly reduces steering effort by approximately 85 percent compared to those models without power steering.

  • Superior terrain capability

    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:

    Variable-speed drive
    Variable-speed driveVariable-speed drive

    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.

    Features include:

    • 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 new 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 vs. previous designs to reduce heat and the amount of water ingestion into the CVT system. The system will reduce belt slipping and improve durability.
    • A low- and high-speed forward gear offering:
      • Low range is 0 km/h to 43 km/h (0 mph to 27 mph), 825M S4
      • Low range is 0 km/h to 24 km/h (0 mph to 15 mph), 855M S4
      • High range is 0 km/h to 71 km/h (0 mph to 44 mph), 825M S4
      • High range is 0 km/h to 51 km/h (0 mph to 32 mph), 855M S4
    • 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
    • Powertrain reduction ratios:
      • The complete reduction ratios range for high gear is (8.6:1 at top speed and 42:1 at initial clutch engagement
      • The complete reduction ratios range for low gear is (17.9:1 at top speed and 86.8:1 at initial clutch engagement
      • 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:

     

    1. As engine speed increases, the spring-loaded drive clutch is closed by weights being forced out by centrifugal force.
    2. As the drive clutch closes, the belt rides up to the largest diameter of the drive clutch and forces open the driven clutch.
    3. With the belt running in the smallest diameter of the driven clutch, the speed being transferred to the transaxle is increased.
    4. 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.
