LDU transmissions
The LDU 20/24 is a U-style hydrostatic transmission with a Z-shaft configuration. It 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 24 cm3 [1.22 in3 and 1.46 in3].
Features and benefits
- Easy-to-use design as a complete hydrostatic transmission package for turf care machines and compact utility tractors up to 26 kW [35 PS]
- Compact design
- Single housing with Z-shaft configuration
- Bypass valve to allow the vehicle to be towed
- Best-in-class efficiency, featuring female piston and male slipper design; overall efficiency of approximately 80% is possible
- Improved kit life, higher duty cycle capability while providing the most compact design in this class of hydrostatic transmission
- Low trunnion operating force
Applications
- Turf care machines
- Compact utility tractors
