rotary cutter gearbox
(one) manufacturer new 45 horse- electricity (more electrical power also avaiable) shearpin gearbox. This gearbox suits many different makes of 4′,5′ and some 6′ rotary cutters. I market a good deal of these boxes every calendar year for many various programs and carry ALL Substitution Elements for this box, but with any luck , you will not likely have to fear about that.
Listed here are the specs on the box:
*45 horse power gearbox
*Standard one-three/eight” smooth input shaft(where the pto shaft hooks on). The pto shaft is held on by a 1/2 shearbolt.
*size of the enter shaft out of the gearbox is 3″ extended
*bolt gap 
sample for mounting is on the corners, four-3/4 middle of hole to middle of hole. It takes a 5/eight” bolt.
