Well I have had my MF620 Snowthrower attatchment hooked up to my MF10 this whole winter and we had about 3 inches of snow this morning so I thought I could go out and give it a try for the first time. Everyone told me the owner that had this before me had always had snowblowed his driveway with this machine and it always worked great, he did his driveway for 40 plus years with this machine so I am assuming it always worked well. Well, its not working well for me. The most i can get the snow to throw it 5 feet tops. i have adjusted the tension on the belt via the MF620 manual, have everything well greased and chain oiled. I have even replaced the belt with the new one. I always spray the chute and auger with silicone spray so that the snow easily flows. I am running the tractor in 2nd gear variable speed 1-2 and I cant seem to win with this thing. Anybody else have an issues? I am also of course running the tractor at full throttle during pto operation. I really would like a snow blade but havn't been able to find one.
