A modular hitch unit is attached to a lawn and garden tractor and then to a tiller. The hitch unit includes hitching mechanisms as well as hand-operable belt adjustment mechanisms for positioning and adjusting the tension of a drive belt. A lever is operated to pivot a countersprung idler pulley to allow the belt to be placed in its operating position. A knob is then turned to adjust the pivotable position of a second idler pulley to control the tension of the belt. The idler pulleys can be switched and the belt remounted to change the direction in which a set of tiller tines are driven.

Abstract:
A muffler system positioned within the engine housing of the vehicle such as a garden tractor, includes a muffler surrounded by an open ended tubular heat shield having a venturi tube on its outer end which receives and accelerates the exhaust gases to create a flow of cooling air through the engine housing and between the muffler and the tubular heat shield for extracting heat from both the engine housing and the muffler.
