rotary cutter gearbox
(one) model new 45 horse- energy (far more energy also avaiable) shearpin gearbox. 
This gearbox matches numerous various can make of 4′,5′ and some 6′ rotary cutters. I sell a lot of these boxes every 12 months for many diverse programs and have ALL Alternative Parts for this box, but hopefully you won’t have to fear about that.
Right here are the specs on the box:
*45 horse power gearbox
*Standard 1-three/8″ smooth input shaft(where the pto shaft hooks on). The pto shaft is held on by a 1/2 shearbolt.
*length of the input shaft out of the gearbox is 3″ prolonged
*bolt hole sample for mounting is on the corners, 4-3/4 middle of gap to middle of gap. It requires a five/eight” bolt.
*twelve splined output shaft(where the blade carrier hooks up on the bottom)
