Re: 550 Oil Leak

Agreed, Ive been guilty of worse though. The C frame can be held with jacks while pins are removed, then lowered with jacks and the blade lift rams. The bushings can then be pressed out but left side pin cannot be fully removed without releasing 2 of the 3 bolts holding the belly pan side cover plat...

Re: Engine weight

The engine on my 550 was a bit under 1000 lbs. I used a friends backhoe to lift it in and out.

While you have it out replace any tube seals you can get to, (6 if I remember right. The local JD dealership quoted me...
