Thank you for the info. Unfortunately that sticker is scratched up and unreadable which is why I am trying to find out.
It runs perfectly at 400 hrs. and I just rebuilt the mower deck with all new moving parts. I stripped and painted the deck also. Lastly I replaced the drag link ball joints and the corresponding rear plastic bushings and the steering shaft bushing, so the steering is nice and smooth with no slop.
I installed new drive and deck belts and I cannot think of anything else that needs serviced at the moment. I do want to change the oil and filter tomorrow. Then it's off to the drudgery of mowing around the ranch....
