how to change a belt on a sears lawnmower?

Answer 1

I believe you are going to have to be more specific. Model? Rider or push?

Answer 2

Get a different brand. Almost any repair will cost almost as much as getting a new one from a better company.

I am biased against Sear's power tools, I had several craftsman brand power tools and they all were poorly manufactured, required constant repair, and were so difficult to work on, compared to other brands that I have since owned, that I was forced to take them in for repairs on anything more complex than changing a spark plug. Before we finally gave up on our Sear's Lawnmower we spent over $300 getting it repaired over the course of 1 1/2 years and it never operated as well as it did during the first use. Now we have a Honda lawn mower, we've spent $100 on repairs over the last 4 years and it operates as smoothly as it did when it was brand new. We had a Craftsman table saw, from before sear's started to make them to only fit craftsman accesories, and it was so difficult to keep properly lined up that we used a radial arm saw instead, and if you know about power tools you know that that is backward from normal levels of accuracy. Sear's intentionally has their equipment made with non-standard parts so that you MUST use sear's replacement parts, but they refuse to sell them so that you cannot make repairs yourself. They then charge an arm and a leg to make repairs, since, on our lawnmower at least, every repair requires a complete teardown and rebuild.

Answer 3

Get a another brand over a 20 dollar belt? Hilarious..

You do have to be more specific...., is it a self propelled pushmower, or rider... or rear engine..

But usually just put the clutch brake on (if rider) to loosen the belt, take the belt guides, and loosen em.. and loosen the clutch pulley (deck or drive, both about the same) and take the old off and put the new one on doing the opposite...
