King Kutter 5ft Tiller Gearbox Seal and Bearing Replacement

Nick350 · Jul 24, 2022

Hey ya'll I'm back with another DIY farm repair, this time replacing the gearbox seals and bearing on a King Kutter 5ft PTO tiller. One day when I arrived at the farm I noticed a large pool of gear oil under the right hand side of the tiller. I ended up tracing it to coming out the tine shaft hub that connects to the gearbox. There are 2 seals inside tucked behind a bearing that were the source of the leak.

If anyone has any questions about the job feel free to ask!

Considering the cost of a new gearbox complete from ASC, I would have just replaced it with a new one...

Maybe I missed it somewhere . . . What is the cost of a new gearbox?

I have the same tiller. It's been used hard and sat outside for about 20 years. Sure hasn't been babied. It does a fantastic job -- it's my favorite implement to operate because of the beautiful seedbed it leaves behind. Well worth repairing! Mine isn't leaking YET. Thanks for the post and video.

Older thread that I missed the first time around... Likewise, I got an old one that has sat outside for it's life. Hope to work with it some this year....
