The gearboxes series are mainly used 
for connecting Hydraulic PTO Drive Gearbox Spped Increaser 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 optimum operating speeds for the hydraulic pumps. RD series of gearboxes are used to decrease hydraulic motor speed.
ML and B series gearboxes supply the connection for hydraulic pumps to low speed tractor power take off. The standard power take off swiftness of 540 rpm, can be increased by the gearbox ratio to optimal speed conditions necessary for the pump. Different inputs are recognized under condition that the output speeds don’t review 3000 rpm.
