In-line belt driven tille drive clutch

A clutching mechanism for a cultivating tiller. The tiller has an engine mounted on a frame with a rotatable output shaft, a rotatable working shaft, and a transmission operatively connecting to the working shaft, the transmission having a rotatable transmission shaft coaxially aligned with the output shaft of the engine. The clutching mechanism includes an upper half pulley attached to the output shaft, and a lower half pulley attached to the transmission shaft, wherein the upper half pulley and lower half pulley are coaxially positioned in a facing but non-contacting relationship such that the upper half pulley is able to freely rotate with respect to the lower half pulley. The clutching mechanism also includes a belt positioned between the upper half pulley and the lower half pulley, and a tensioning assembly configured to selectively tension the belt so that the belt transmits rotation of the upper half pulley to the lower half pulley.
