HHT 4WD 575

  • Engineered from the ground up using heavy-duty components, the HHT 4WD is available in 575 hp. The frame is manufactured from thick steel plate to ensure structural integrity, even under extreme conditions. Outboard planetary axles with a new 24 bolt pattern and standard drum duals ensure power is efficiently transferred to the ground.

    Axles and Drawbar


    All models feature a large, reliable heavy-duty planetary final drive to provide long service with heavily ballasted tractors and big implements. Large bearings support the planetary hubs on the axle housings. They are built with large axle tubes and planetaries capable of standing up to heavy weights and capable of handling increased bending loads associated with wide dual or triple wheel options.

    Outboard Planetary Axles - In the 1970’s, Versatile engineers developed the outboard single reduction planetary axle, known in the industry for its strength, simplicity, ease of service and wheel mounting. The tradition of building the most reliable planetary combination in the industry starts with placing the planetary and sun gears towards the outside of the axle. Outboard planetary axles deliver all available horsepower through a large, precision machined floating sun gear. The planetary hubs are suspended on large diameter bearings mounted directly to the axle tubes. The load is supported by the axle housing assembly and not by the drive train components. All Versatile four-wheel drive tractors feature reliable final drives that deliver horsepower where it counts: at the drawbar.

    The planetary axles remain on the tractor during routine maintenance, limiting downtime. Daily inspections are easy with a quick visual check of the axle oil level indicators. The gears can also be reversed to extend the wear life.

    Drawbar - The drawbar pull point on Versatile four-wheel drives is immediately behind the articulation point, which features a large-diameter pivot pin for maximum strength and durability. The articulation area is kept as open as possible to provide easy service access to the drivelines and the transmission.

    The thick 2" (51 mm) hitch pin can be fitted with an optional 1 1/2" hitch pin and bushing kit for implements that require less horsepower.
