Started by following instructions given in manual but, found an easier way to perform job. Removed deck and pulley plates from underside of mower. Had to use snap ring pliers to remove snap ring from steering gear and remove gear. Pulled up steering wheel to get belt out past it. Installed new belt.

Living 75 miles from nearest repair place, and not an electrical guy, I replaced parts that were instrumental to start the mower. Youtube videos helped on most things, and most parts swapped out with minmal effort with common tools. BUT the replacement of the primary belt was from the lower bowels of the earth! You need to remove the mowing deck, and it helps to really get this tractor off the ground onto ramps and jack up the rear end so you can get underneath. Everything else was easy. Trouble is I'm 76 and have cancer which really messes with logical, sequential thinking. The problem with the starting issue was that I needed to replace the solenoid, the only part I didn't buy a replacement for---naturally. So I had to use a temporary, bypassing momentary switch to get the tractor to run, which it did---nicely. Having not done any of this work before, this replacing business has been an adventure. Thankfully, eReplacement people helped me through it with timely advice, and great replacement parts. They are my go-to people! Great pricing too!

Belts that were on the machine when I got it were B belts normal V type, and what would happen the speed increaser would bind and the mower would lock up. ordered the factory Murray belts and pulleys and come to find out the belts were B type but did not have a V shape more flat. Installed the new belts and pulleys problem solved runs great. Remember always use the factory or trusted after market parts, saves lots of tine.
