The gearboxes series are used mainly allowing you to connect hydraulic pumps to the energy take-offs of agricultural tractors. PTO output, standardized at either 540 or 1,000 rpm, is, in this manner, increased to Hydraulic PTO Drive Gearbox Spped Increaser maximum operating speeds for the hydraulic pumps. RD group of gearboxes are used to decrease hydraulic motor speed.
ML and B series gearboxes provide the connection for hydraulic pumps to low swiftness tractor power take off. The standard power take off velocity of 540 rpm, can be increased by the gearbox ratio to optimum speed conditions required 
for the pump. Different inputs are recognized under condition that the result speeds don’t review 3000 rpm.
