I have two of these machines. Handy tractor for the size. I use them also for residential drives and walks with a 51 inch front mount blower. Yesterday I finished with it by our house and I barely could get back home. Something sounded like it was up in the front axle / wheels. I dont think its the hydro but going forward I almost came to a stand still, back off a bit and limped it my garage. Ideas? Going to bring it in tomorrow at a NH dealership. Hate to but I am not sure what it is and at $90 an hour, fix it bill gets expensive!
