Original product of the Rolmus brand, symbol: 1.45.10.029.90.1 31

Application:

The gear increases many times rotation speed of the hydraulic pump shaft relative to the source drive. Enables high pump efficiency at low PTO drive shaft revolutions.

Perfect for driving GR3 hydraulic pumps requiring high oil flow in forestry and construction machines and many tractors, including C-330, C-360, C-385, ZETOR, MF others with a typical PTO drive with a 1 3/8' shaft.

The PTO socket with which the gearbox is equipped allows it to be mounted directly on the PTO drive shaft of a tractor or machine. A special latch prevents the gear from sliding off the drive shaft.
