<p>A folding tiller handle is made in two pieces connected for limited relative longitudinal and pivotal movement, one piece being a permanent part of the basic tiller assembly. A belt tightening idler sheave is associated with a belt drive which provides the motive force for rotating the tiller tine assembly. A control, which includes two separable rigid rod members, moves the idler sheave into and out of tightening engagement with the drive belt. The rods are joined through a connection which imparts rotary motion from one rod to the other and which also permits relative longitudinal movement therebetween to separate the rods. The rods are associated with respective pieces of the tiller handle so that when the handle is separated or folded, the control connection to the tightening sheave through the rods is interrupted and the drive belt cannot be tightened to establish the tiller drive.</p> |
