Small Engines (Lawn Mowers, etc.)/Sears Roto Spader


QUESTION: i have a sears 8 HP Roto Spader im just trying to figure out the way the belts are supposed to go around the pulleys it has 2 belts,also forward neutral revese handle. if you know where i could find a manual or diagram and tensions,no luck at sears. thank you

ANSWER: Is there a model number on the tiller?  Sears always puts a sticker with the model number somewhere on the machine.  It will be a long number, something like 123.456789.

As a rule of thumb, to figure out belt routing, if the pulley is a V pulley the V part of the belt goes in the V pulley.  If the pulley has a flat face, then the back or flat part of the belt rides on the flat pulley.  This basic rule has helped me out countless times when I did not have the old belt to figure out how to install a new belt.

Let me know what the model number is.

QUESTION: sorry i left it out by mistake model number is 785-62718-322

Did you Google the model number or go to Sears web site and look for the manual?

For some reason the US internet, or Sears web server, prevent me from searching the Sears Canada website.  Don't know why but I can look up Canadian snowblowers either...I know they are made my MTD and sold through Sears and other stores in Canada.

Try the Canada Sears website and see if you can find the model number.

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.
