Belt drive for lawn mowers

摘要

A lawn mower drive arrangement delivers power to a mower deck of a lawn mower vehicle. The drive arrangement includes a prime mover and a drive sheave, at least one mower deck sheave for powering at least one cutting blade and an endless engaging the drive sheave and at least one mower deck sheave. The drive sheave is oriented such that its axis of rotation is generally transverse. Guide pulleys engage the tension side and the slack side of the endless belt between the drive sheave and at least one mower deck sheave. The guide pulleys are positioned such that the endless belt twists by an acute angle substantially less than 60 degrees between the drive sheave and the guide pulleys.
