rotary cutter gearbox
(1) model new forty five horse- electrical power (far more power also avaiable) shearpin gearbox. This gearbox fits numerous distinct can make of 4′,5′ and some 6′ rotary cutters. I promote a whole lot of these bins every single yr for numerous diverse applications and have ALL Alternative Components for this box, but ideally you will not have to fret about that.
Here are the specs on the box:

*Common 1-3/eight” clean enter shaft(the place the pto shaft hooks on). The pto shaft is held on by a one/two shearbolt.
*length of the input shaft out of the gearbox is three” lengthy
*bolt hole pattern for mounting is on the corners, 4-three/4 center of hole to center 
of gap. It will take a five/8″ bolt.
