Vic,
The brakes are the problem. (sitting in the seat) the left brake is completely missing, housing and all internal parts, right brake has the housing or drum which ever you call it, but internal parts are gone or broken. The only info I can give you at present is this from the data tag:
L-3500; 10420; DS1900; 36ps; 2740rpm. I know it would be difficult to get parts sent here(Thailand), from where you're at, but if you can find them I'll have you send them to my Michigan address and I'll just bring them back next year when we return in December. If the info I gave isn't enough I'll go to town and get whatever is needed(tractor is at the kubota dealer in town). Thanks for the reply and I hope we're on the way to getting this tractor back to work. FarmerDon
