Abstract: A hood hinge mechanism having a pivot pin having a D-shaped cross sectional shape positioned within a recess. The hood and pin are pivotal to a position whereat the D-shaped cross section is oriented to pass through a slotted opening to the recess to thereby allow the hood to be removed or installed on the vehicle. A bracket coupled with the hood abuts a support member when the hood is pivoted to its fully open position such that the hood is held open by the weight of the hood and is generally blocked from being detached from the vehicle unless acted upon by an operator.

Abstract: A vehicle having a vertical shaft engine mounted to the vehicle frame via elastic mounting units which allow vibratory motion between the engine and the frame for reducing the amount of vibration transmitted from the engine to the frame during operation of the engine. A cooling fan is positioned directly above the engine for pulling air downwardly through a radiator positioned directly above the engine and fan. The radiator is supported in its position above the engine by being rigidly fixed with support members. The support members are rigidly fixed with and extend upwardly from the frame. The radiator is held in position by the support members and is not supported by the engine, and therefore the radiator is generally isolated from engine vibrations by the elastic mounting units.
