A hydraulic pump is a mechanical device that converts mechanical energy into hydraulic energy (flow and pressure).
Hydraulic pumps use hydraulic fluid dynamics (oil can’t be compressed, whereas air can) to perform a variety of functions such as:
• Lifting & lowering parts (cutterbars, buckets, forks).
• Operating steering and braking systems.
• Operating hydraulic transmissions (with hydraulic motors).
A hydraulic motor converts hydraulic energy into mechanical energy. The hydraulic pressure and flow generate forces and move the tractor. As a key part of hydraulic transmission, the motor is able to deliver:
• High torque at low speed.
• Force and torque at a constant level.
• Variable speed: (CVT or Powershift).
• Near-instantaneous shift to reverse motion.
