Mend MTD 12.5 Oil Leaking Engine

What would cause oil leaking from around the shaft under the motor?

I have an MTD 12.5 riding mower that is leaking oil from under the engine. Oil is collecting on top of the pulleys. Could this be the seal to the shaft? How hard is it to repair at home?

Hi Holly, It sounds like your bottom seal on the engine is gone. This is a common thing because there is a lot of tension on the drive pulley attached to it when the deck is engaged. To replace it, the pulley has to be removed and the engine removed. It is quite a big job. I would suggest you get some one with some experience to do it.
GOOD LUCK
