BDU transmissions
Our BDU transmissions are available in three sizes, with displacement between 10 cm³ and 21 cm³ [0.37 in³ and 1.28 in³]. They contain variable-displacement pumps and fixed-displacement motors, both of which feature axial piston designs and spherical-nosed pistons.
LDU transmissions
An LDU hydrostatic transmission features a U-style layout and contains a closed-circuit variable-displacement piston pump with direct displacement control (DDC) and a fixed motor. Optimized for performance, size, and cost to meet the demands of today's mobile applications, these transmissions are available with displacements between 20 cm³ and 31.5 cm³ [1.22 in³ and 1.92 in³].
