Hello! I've been a long time reader, never having a big enough issue to post about until now. Hopefully someone tells me it's a simple fix because I'm not sure how long my warranty is. I'm right at 100 hours now on it and bought it in April 2006. My HST the first year was great, I actually tried high gear (not full speed, just to get a feel for it) a few times when I first bought it and was snowblowing only 3 or 4 inches on flat pavement and it worked great. Now, with no implements running and being in 2 wheel drive, all warmed up I can barely go at all in high gear. Middle gear even gave me problems tonight when I drove it to my dads house about 1 mile away. In middle gear, I was going up a small grade and tried moving my bucket up and down and I actually had to stop the tractor and let it catch back up because it bogged right down and almost quit. In both higher ranges, it works perfectly at first, takes right off. High gear bogs after about 10 seconds, maybe just a little longer if going slightly downhill and middle gear only when going uphill or for a distance. This started last winter, but seems to have become worse this winter. I don't notice it as much in the summer in middle gear because I only mow and pull logs, but have pretty much gave up on high gear for anything. I guess if anyone has suggestions or knows what the warranty period is, that would be most helpful. Oh, maybe not related, but the only other problem I have is the loader valve. It sticks in the float position, sometimes I have to take pliers to it to pull the plunger back out.
