Available on the CT335, CT445, and CT450 tractors from Bobcat, the new semi-synchronized gear transmission option provides the tractors with 12 forward gears, 12 reverse gears, and shuttle-shift capabilities. The SST transmission provides optimal power take off (PTO) output and efficiencies for use in applications such as mowing, tilling and other rear-PTO-demanding applications, Bobcat says. Tractors equipped with SST are ideal for applications such as spraying and seeding, where a specific speed needs to be maintained.
