PTO Gear Box

AGRICULTURAL P.T.O. GEARBOXES FOR PUMP DRIVES

GP-PTO

Pumps from Group 2-4


 


Power up to 27 KW


PTO gearboxes use a gear ratio to increase the speed of drive from a tractor PTO to a higher speed more suited to hydraulic pumps. Typical applications are when the oil flows & pressures required to drive implements or machinery cannot be obtained from the existing tractor hydraulic system.
 

 

 

ADVANTAGES


MALE OR FEMALE TRACTOR P.T.O. INPUTS

Gearboxes are supplied with either a male or female tractor PTO input shaft.

INTERNATIONAL DESIGN

Units provide a step ratio of 3.5:1 & conform to the SAE standard J 178D.

SAE OR EUROPEAN PUMP FLANGES

Pumps inputs are available conforming to either SAE or European four bolt standards.

TORQUE BAR MOUNTINGS

It will be necessary to fit a suitable torque arm or PTO shaft between the gearbox & tractor transmission.

Operation

Whilst PTO gearboxes can be used for continuous duty applications care should be taken not to exceed the thermal capacity of the gearbox. In certain applications it is possible to use hydraulic oil to continuously flush the gearbox & thereby increase its effective thermal capacity.

Lubrication

PTO gearboxes use EP80 gear oil, which is ideally suited for normal applications. However, regular oil changes and attention to oil levels will help to extend unit life.
