Gear Boxes

Gear Boxes For Rotary Cutter's, Shredders, and Choppers Featuring Boxes from 40hp to 100 + hp

Notes: 

  • When searching for a gearbox, there are several criteria that need to be considered: 
  • These are the number of splines on the input shaft or is it smooth, that is a shear bolt (the input shaft is the shaft that attaches to the PTO drive line). 
  • The diameter and the number of splines on the output shaft (blade shaft). The number of deck mounting bolts and their position on the gear box. 
  • Gearboxes vary with the application. When two gearboxes are used on 8' and 10' rigid deck cutters, they must be matched in exact gear tooth count. On these boxes the blade arcs overlap. If they aren't the same, the blades will strike during the operation causing damage to the blades, boxes and the cutter itself. 
  • If you have any questions at all regarding gearbox suitability, whether your new box is compatible with your existing box, please call us at 937-242-6637.

Here at Tractors And Equipment Online we have been very successful at finding and facilitating the installation of modern gearboxes on current and aging cutters that are out of production or obsolete.


The photos below will give you an idea of what the installations look like. 

If that is the situation in which you find yourself give us a call, what do you have to lose?
