my fathers lawn tractor is a simplicity lawn tractor,i think 14 hp and 42" cut. the manual says to change the rear end/trans oil
with 10w30 engine oil. this has never been done in almost ten years,should this be changed or should i leave it alone because he has no problems so far. what would you recommend for oil for this. thanks

Rotella T Triple Protection. You should be able to get gallons at WM for cheap. You can use it in the engine too if that's the correct weight.

I'd swap out the factory fill if it was my equipment. Actually, I'd probably do it annually with the motor oil if it was easy enough to do both, but that's just my OCD.

How often does the manual say to do it?

Assuming it's hydrostatic drive.. and probably a Tufftorq, yes, TT of that vintage typically recommends 10w30.

Like said, a more suitable oil would be something like Rotella-T 15w40.

If it's a TT you can go to their website and get the updated spec.

Mine runs 15w-50
