This belt is a perfect fit for the Lesco 36” walk behind mower! The mower is belt driven with a 5 speed transmission. This belt is the one from the engine output shaft to the transmission input shaft. The mower is no longer manufactured and thanks to the V-Belt Guys and their knowledge of part numbers and cross referencing abilities I was able to easily obtain the correct belt! The part was in stock. Ordering was easy and shipping was fast! I highly recommend this company and will definitely order from V-Belt Guys again.
