Put zero turn on cinder blocks to get higher up to replace pulley ,. Took lots of time removing it. IGÇÖm a woman and had help from a good friend that was 70 years old. Together we removed old part and replaced new idler pulley. Then replaced belt. Mower still didnGÇÖt move forward or in reverse. We didnGÇÖt know how belt went on so I sou ght the help of a repairman to tell us how it went. After replacing belt on right , I was back in the moving business. Sure would have helped if instructions were in box. I used google and you tube, with little to no help on my zero turn. Lots of information on there. It didnGÇÖt help with my problem. I bet I know how to replace if this ever happens again. Sure hope it doesnGÇÖt. A younger man could of done this work in no time at all.

Take the spring off of the top part of the idler arm. Slide an open end wrench between the top of the idler arm and the frame to hold the top nut. Then I used an air impact to take the bolt out. I also used it to reinstall because the bolt is very long. About 3 1/2GÇ¥. You can do it with just a ratchet but it will take a while. It is also easier on reinstall if you have a second person start the nut on the top side because you cannot reach both sides at once. Replace the belt and put the spring back on and youGÇÖre back in business.
