Abstract: The front wheel suspension assemblies of an ATV are configured with translation assemblies aligned along a translation axis generally parallel with the vehicle axis. These translation mechanisms are engaged by pivotal follower assemblies attached to a ball joint which are moveable along the translation axis either by the pivoting action of the suspension control arms or by a motor driven system.

Abstract: A hydraulic grapple apparatus and method for use of the same are disclosed. In one embodiment, the hydraulic grapple apparatus includes a support frame for attachment to a skid steer loader. The support frame has upper and lower guide tracks arranged in vertical alignment with each other and spaced apart in order to define an open channel therebetween. First and second grapple jaws are mounted on the upper and lower guide tracks for lateral movement along the support frame. First and second double-acting hydraulic cylinders are disposed in the open channel and coupled to the support frame. The first and second double-acting hydraulic cylinders independently actuate the first and second grapple jaws, respectively.

Abstract: A manually operated switch lever moves arm 105 along resistor 113 to generate a "raw" motor speed demand signal which is amplified and inverted by amplifiers 115 and 119 to form a "base line" demand signal.The "raw" demand signal and a motor load signal at the output of amplifier 154 are compared in amplifier 125 to generate an "error" signal. The "error" signal and the "base line" demand signal are summed in amplifier 129 to form a variable reference voltage which is applied to the non-inverting input of comparator 132. The second input to comparator 132 is a triangular shaped wave which is centered about V/2. When the amplitude of the oscillator output wave exceeds the reference voltage, the output of the comparator 132 is low and switch 160 is off. Thus, variations in the D.C. reference voltage at the output of amplifier 129 control the ON-off duty cycle of MOSFET switch 160 to adjust the power applied to motor 106.
