The SS500 range of transmissions combines on the move, fast, easily operated electro/hydraulic direction control with 4-speed mechanical gearshifting using proven technology and well established design principles. These units achieve high standards in earthmover and on/off road transmissions reliability. The reversing shuttle, for example uses multi-disc hydraulic clutch packs to achieve direction changeover simply by locking helical gears to the input shaft - avoiding the complexity of epicyclical gearing. A 'split' layshaft/mainshaft arrangement keeps the drivetrain clusters tidily around the shuttle, economising on interior space and keeping the gearsize to a minimum.

Electro/hydraulic actuation of the reversing shuttle means that in-cab control can be positioned wherever it is most convenient. With the fitment of live power take off, ancillary equipment and pumps can all be power fed by easy access to the side of the transmission.
