    Gator TH 6X4 drive systemGator TH 6X4 drive system

    The Gator™ TH 6X4's power is transmitted from the transaxle to the center axle. The rear axle is driven by roller chains from the center axle.


    1. High flotation tires
    2. Transaxle
    3. Chain drive
    4.  Engine
    5. Variable-speed drive

    Key elements of the drive system are as follows:

    Variable-speed drive


    The variable-speed drive consists of two clutches connected by a drive belt:

    • Drive clutch is attached to and rotated by the engine.
    • Driven clutch is attached to and drives the transaxle.

    Features include:

    • Infinite selection of speeds (0 km/h to 32 km/h [0 mph to 20 mph])
    • No shifting necessary as operator increases speed
    • Adjusts speed to the load to avoid bogging down when going up a hill or through challenging conditions because the wrong gear was selected
    Variable-speed driveVariable-speed drive


    1. Idle speed
    2. Moderate speed
    3. High speed
    4. Drive clutch
    5. Driven clutch

    Here is how the variable-speed drive works:

    1. As the 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 the drive speed upward or downward, so the engine rpm remains constant at constant throttle position.



    The transaxle is fully enclosed and runs in oil for reliability.

    Helical gears are used for quiet operation.

    The differential design reduces scuffing of the turf during turns because the inside wheels turn slower than the outside wheels (vehicles that have a solid axle shaft must skid the inside wheel when making a turn).

    Traction assist (differential lock) is built into the transaxle:

    • Allows locking the rear drive wheels together
    • Provides increased traction in tough spots

    The neutral start safety interlock is provided for the engine ignition system.


    Bolt-on cast-aluminum rear axle housings provide an extremely strong supporting structure.

    • Large, sealed bearings are located inside the housing for better protection
    • Forged-splined shaft for increased torsional strength
  • Features operating conveniences such as high-back seats, cup holders, 12-V outlet, glove box, and fuel gauge
    Side-by-side bucket seatingSide-by-side bucket seating

    Numerous features offer the operator and passenger a comfortable ride and provide many operating conveniences.

    • Side-by-side bucket seating provides room for one operator and one passenger
    • Hip restraints serve as a handhold and help to keep the operator and passenger in their seats over rough terrain
    • Both seats tilt forward for dry storage and ease of service
    • Choice of adjustable or non-adjustable driver's seat
    • Hour-meter is standard to assist in maintaining regular service intervals
    • Integrated cupholders
    • 12-V outlet located on instrument panel
    Convenient walk-through operator stationConvenient walk-through operator station

    The control location and walk-through platform provide easy entry/exit for operator and passenger.

    NOTE: Shown above with the optional front bumper, brush guard, front fender guard, and floor mat.


    NOTE: The front bumper is standard on the Gator™ TH 6X4 Diesel.

    • All models feature a park brake indicator light, hour-meter, and tank-mounted fuel gauge as standard equipment
    • Traction assist (differential lock) is hand operated and conveniently located between the operator and passenger seats
    • Traction assist indicator light (Gator TH 6X4 only)
    • Glove box is located in the dash to provide a convenient storage area for small tools and the operator's manual
    • Grab bar is provided for the passenger
    • Center-mounted key switch
    • Additional storage is provided between the seats

Fantastic value!


We purchased our first 6x4 diesel in 2001. I simply don't know what we would have done without it over the past 14 years. I am now looking to buy a second Gator since my wife is always using ours when I need it. Every family should have two!
