Small Engines (Lawn Mowers, etc.)/Yard Machine Drive Belt


42 inch 18 hp...trying to replace transmission belt...The drive pulley is located too close to the frame to get the belt onto the pulley...when I tried to remove the pulley retaining nut it torqued against the transmisdion and the wheels rolled...I was afraid to bear down too there a trick to getting the belt onto the pulley or an easy way to remove the pulley nut?

What is the mower model number?  The model number is on a sticker, about the size of a business card, and will be in a format similar to xxx-xxx-xxx or xxxxxxxxxx.

As far as a trick to remove the pulley nut, and air impact gun is the trick.

An alternative trick you can use is to loosen the transaxle bolts and jack the mower up allowing the transmission to drop just a little to install the belt.  Sometimes you can even remove a couple of the bolts allowing the transaxle to drop a little and tilt as well.

Let me know the mower model.

Born and raised in the midwest. Started tinkering with engines when I was about 14 on my Suzuki RM-80. I began lawn mower repair at a small hardware store. I knew absolutely nothing. I read lots of repair manuals and met an older fellow who taught me many lessons. I continued working on small engines through high school and paid my way through college working on mowers at the same hardware store. Decided to get away from the midwest and mower repair so I joined the Air Force. I repaired air traffic control electronic equipment and ended up in Hawaii where I got a part time job at Small Engine Clinic. I gained a lot of experience from the Small Engine Clinic and had a blast repairing small engines. I then took the Briggs and Stratton Master Service Technician test and earned my MST. I then traveled to Wisconsin where I attended the factory update training seminar and received formal training. Continued working on mowers part time as I completed 20 years of military. Retired from the military on a Friday and continued in the lawn and garden industry the next Monday.
