77 oliver gearing

Does anyone know if there is a slower gear that can be put in a 77 oliver ?

jim, most 77s came with a 11/50 pinion and ring gears, a 9/48 pinon and rig gear was also available. i have a 9/48 in my 77. years ago my dad had them put in to handle the chopper better. little did he know that it would help make it good for tractor pulling. chuck

Thanks, Pulling is exactly what I am doing and that is the cheap way around H.P.
