This innovative, patented clutch system – a GT exclusive—engages automatically through tensioning the drive belt, while speed is adjusted by feathering the control bail. The use of a dual output shaft (MA 302, 402, 502) eliminates the need for a freewheel system in the wheels.
When smooth engagement is a high priority, a cone clutch is an excellent solution, providing an ideal combination of transmissible torque and control ease. MC models have the option of V-motion variable speed control for increased flexibility and user comfort.
Thanks to its internal, lever controlled dog clutch, the MD series enables easy installation in the mower deck while providing durability and high torque at a competitive cost. MD models have the option of V-motion variable speed control for increased user comfort and convenience.
The innovative MS series combines the smoothness of a cone clutch with the durability and torque delivery of a dog clutch. The effort needed to maintain transmission engagement is among the lowest in the market, for increased operator comfort. MS models have the option of V-motion variable speed solutions for increased user comfort and flexibility.
The following variator models are available to upgrade MC, MD and MS series transmissions to variable speed.
The MG Series 3-speed gearbox provides the perfect job-to-speed ratio demanded by turf professionals and homeowners with large properties. Cone clutches provide smooth engagement and low control effort, making it the right choice for heavy-duty applications. MG models have the option of built-in freewheel systems to reduce maintenance.
MV Series transmissions utilize a continuously slipping cone design, giving the operator the ability to match torque delivery to the job at hand. A high torque rating makes an MV transmission perfect for heavy-duty commercial mower applications.
