Claim:
A tiller for cultivating the soil, the tiller comprising: a frame; a power source mounted on the frame having a rotatable output shaft; a rotatable tillage shaft having a plurality of tillage tines mounted thereon; a transmission operatively connecting to the tillage shaft, said transmission having a rotatable transmission shaft coaxially aligned with the output shaft of the power source; a clutching mechanism selectively engaging the transmission shaft to the output shaft of the power source to thereby enable rotation of the tillage tines for tilling the soil, said clutching mechanism comprising an upper half pulley attached to the output shaft, a lower half pulley attached to the transmission shaft, a belt positioned between said upper half pulley and said lower half pulley, and a tensioning assembly configured to selectively tension said belt so that the belt transmits rotation of the upper half pulley to the lower half pulley.
