In late May of this year (2020) I bought a 2018 Mahindra 2555 HST with 264 hours on it. From the dealership it seemed to be a solid machine. With the tractor I bought a grapple so it took a couple of weeks to get that in and rigged out. I finally got the tractor to the farm to put it to work. Within the first two hours I started to have issues with forward and reverse, the tractor wouldn稚 go or would buck in either direction. Called the dealership and they said to check the two plugs on the right side under the floor board to see if they had water in them, we had a major down pour and the tractor was setting out in it. I got an air hose and blew out the plugs, replaced, and all was fine for the rest of that day, the very next day same thing. I repeated the procedure but this time it didn稚 change, the tractor still had moving issues. Loaded it up and took it back, after a couple of weeks they finally replaced the main HST module. Now the tractor has 304 hours on it and I am having the exact same issue. I cleaned the floor board plugs again and again the tractor ran all afternoon with no more issues, went out two days later and didn稚 get 400 yards when it stopped, wouldn稚 go forward or reverse. Took me a good 30 minutes to get it back to the barn. The warrantee has ran out and was the first time but because I had just bought the tractor they covered it. I don稚 think the HST module has gone bad again and now not sure if that was the issue in the first place. Any advice or help would be much appreciated. I really don稚 have time to let the tractor set in a shop.
