Abstract
A variable speed pulley or sheave with a broad speed range is designed particularly for self-propelled lawn mowers. The variable speed pulley is mounted on a drive shaft of a gear unit in the form of a transaxle or transmission located on the mower and is driven through a belt connected to the drive shaft of the mower engine. The engine drive shaft can also drive a mower blade, thus eliminating any special power take-off shaft otherwise required to propel the mower. The variable speed pulley includes two pulley members or halves which are designed with inter-nesting tines and recessed hubs which enable the pulley halves to nest together more fully and thereby increase the speed range by more widely varying the effective diameter of the pulley.
