Going into 1300 hrs on my TC33 and had to look at something in the manual. I saw a valve adjust recommended at 800 hrs. Anybody done this? I searched here and didn't get any posts covering this issue. May be smokin alittle more than usual, hard to tell. Also i have original fanbelt. Anyone change this as pm? or just wait til it looks ratty. I am keeping some hours offf the Boomer since I bought a 52" Toro ZRT for my close-in work 5 yrs ago. I used to drop my wing mowers and cut grass around the house with the tractor alone.

My 1700 has 600 hours on the interval. I checked mine at 1300 hours and two valves were .001-.002 tight. I bought used at 950 hrs so I don't have any idea if the then owner checked at 600 hours.
