Today while I was mowing the pump drive belt went out on my 52" Lazer Z HP. I didn't have an extra so I called a place I knew might have one. It was almost closing time, and they had a belt in stock so I bought 2. Well I should have double checked the part numbers first. Once I was home I figured out that I had bought a drive belt that was for a 48" Lazer HP. My question is: Are the belts for the 52" close enough in size to the 48" to use for a day or so? No one will be open until Monday and I have lots of lawns to cut.
