2000 Murray 12.5 40 wide body Drive belt problem
Ok,I replaced the belt a couple days ago with a Murray OEM belt, re-adjusted the clutch and it worked fine as I mowed 3-3 1/2 hours per day for the last 2 days. The property is 2 1/2 acres and the area I have been mowing has not been mowed in about 2 yrs(lots of blackberrys and 1/2 to 1in trees,i know I shouldn't be mowing down those trees but will be replacing deck belt and blades when finished), and I'm 236lbs which shouldn't make a difference. I stopped at about 3 hrs yesterday(all was still running fine) and went to the store for more gas. When I got back to mow round the hose, I put it in 1st gear and the new belt slipped off tranny pulley, put it back on, came off again as soon as I released the clutch. So I re-adjusted the clutch again since I worked so hard with such bad ground to mow and figured it had stretched a little, again it came off as soon as I released the clutch so I gave up for the day. Today I removed the deck and battery to see what the problem is and noticed thru the battery hole that the tranny pulley leans down toward the rear and up towards the front of the tractor, so I removed the rite rear tire and have pics to share. What I also noticed is the tranny brackets mounted to the outside of the frame are bent upwards where they mount to the tranny towards the front of the tractor and have also been welded (by the previous owner i suspect). Would this cause the belt to come off like this? The bad area of the property is also a little rutty and very rocky(moved rocks out of the way when I could see them) so this made for a very bumpy ride and I used 1st and 2nd gears only while mowing and 3rd and 4th when not cutting(very bouncey ride when going faster).Should I try to straiten those brackets out or buy new ones? How can I remove them where they are welded(both brackets on each side are like this)?
