77 standard/industrial gears

Derek Young · Mar 25, 2014

I am in desperate need of ring and pinion gears for an oliver 77 standard or industrial. Going to place them in my row crop so I can keep up on tractor drives. Any ideas and information is greatly appreciated.

I'm not sure if a super 77 would be the same, but I have a super 77 diesel industrial that i'm thinking that I might part out if your looking for a set yet

Derek, Do you know what ring and pinion you have now? Most of them came with 11/50 which go about 12.6mph at governed rpm and if you increase the rpm a little it should run with most, but if you have the 9/48, they only run about 10.5 mph. If they are the same as the 770's it's the trans. gears that are different not the ring and pinion. Chuck
