Well-designed Muli drive train

The REFORM Muli models are available either with a mechanical gearbox or with a hydro-mechanical gearbox.


REFORM Mulis are equipped as standard with a synchronised splitting gearbox and can be equipped with a 40 or 50 km/h gearbox, depending on the model. The 8 forward gears are subdivided into 16 gears by a splitting group, creating even finer speed stepping. For reversing, it can also be subdivided into 8 gears. For use in slow working mode, an optional finely stepped creep speed gearbox with 32 gears is available, which makes extremely slow speeds possible.

The advantages of the Muli speed change gearbox at a glance:

  • Narrow and field orientated gear stepping
  • Low moving-off speeds – essential in extreme terrain – with 8 gears in the main working range between 4 and 12 km/h
  • Large overlaps between the gears
  • Safe, quick and smooth gear shifting with synchronised speed change and shuttle gearbox
  • Short, precise shifting travel directly into the gearbox thanks to the shift rod
  • Preselectable splitting group for anticipatory driving
  • Working speed optimally matched to PTO speed for maximum productivity of attachments


The demands on the Muli are becoming more diverse and require different drive concepts depending on the attachment, operating speed and load torque. Each drive concept has its advantages and disadvantages. The REFORM HybridShift gearbox, however, now makes it possible to combine the advantages of a hydrostatic drive in work mode and a mechanical drive in road mode without sacrifices.

In road mode, nothing beats the efficiency of a mechanical gearbox. The vehicle can be driven economically in particular when fully loaded and in the high speed range.

Applications such as road sweeping, snow clearing from parking lots and washing reflector posts require frequent changes of direction or stop-and-go operation. A hydrostatic drive is the best solution in this case.


In mechanical mode, the hydraulic components are separated from the drive train. The drive is 100% mechanical (blue) without any loss of efficiency from the hydraulic system. This mode is identical to the mechanical Muli gearbox, except for the creep speed mode, which is a hydrostatic unit here.

After changing to hydrostatic mode, the hydraulic components, hydro-pump (yellow) and hydro-motor (green) start working. The hydrostat system can be controlled across 4 gears and two groups. The driving direction is changed via a rocker switch on the joystick.

Mechanical drive

In road mode, nothing beats the efficiency of a mechanical gearbox. The vehicle can be driven economically in particular when fully loaded and in the high speed range.


Depending on application, the operator can choose between the speed change gearbox and the continuously variable gearbox. Switching is done by a control lever.

Hydrostatic drive

The hydrostatic drive makes safe starting and stopping possible even on extremely steep slopes, taking the driver and vehicle safely through everyday work.

Protected rear PTO

All Muli models are equipped with a rear PTO as standard. The rear PTO is driven by the centre of the centre tube directly from the rear axle gearbox to the attachment. This ensures that the rotating parts are always optimally protected. Depending on the model, 540 or 1,000 rpm are available at the rear PTO. Depending on the Muli, an optional front PTO with 540 or 1,000 rpm can also be installed.
