rear oil leak on my zero turn. easy to fix?

i have a rear oil leak on my kubota zd18.

it's looks like it's coming from the very back of the motor.

i don't know very much about motor. it looks like it may be leaking around the rear shaft. there is a gear back there which attaches to a big weight.

anyone know what is causing this? rear main seal possibly??? is this east to get at and fix??

i was doing some very heavy rough cutting today do you think this is why it failed(started leaking?? it's not leaking very badly. i noticed a very small puddle in the trailer.

Check to see if anything got wrapped around the rear shaft, grass, string etc. I've seen this happen before and it can cause the oil seal to leak. What year and how many hours on the tractor?

What I had happen on my 757 was the rear seal bearing was not set in. I simply had to go to a shop and get the bearing replaced, and I got the rear seal replaced and all was well.

Thats not many hours, especially for a Kubota. I've had many Kubota's and luckily never had that paticular problem. Unfortunately you are out of warranty. If you want to attempt the repair yourself, I would get the shop manual. Also check with Kubota to see if they ever heard of this problem. Good Luck

well i talked to kubota dealer. most likely it's just a seal. hopefully i don't have a bad bearing or something.


it's leaking right around the fly wheel area.
