Patent ID: 7721828

Claim:
An adjustment device for matching speed of lever actuated variable speed drive motors on a skid steer vehicle comprising: a bellcrank that pivots to change the speed of a drive motor,: a control lever mounted on the bellcrank and moveable from a neutral position to a forward speed position wherein the motor is in operation at a corresponding speed; an adjustable position stop screw accessible from an operator's compartment for engaging and stopping a moveable portion of the lever at the forward speed position; a bracket configured to hold the stop screw in position; an adjustment nut positioned on a lower surface of the bracket, the adjustable position stop screw extending through the bracket and the adjustment nut; and a stretchable retaining strip engaging a first portion of the stop screw on a first side of the bracket and engaging a second portion of the stop screw to restrain rotation of the stop screw, the second portion of the stop screw extending through the adjustment nut such that the adjustment nut is positioned between the stretchable retaining strip and the bracket, wherein the retaining strip is stretched over a portion of the bracket and, as a result of the stretching, imparts restraining forces on the stop screw, at both of the first and second portions of the stop screw, to restrain rotation of the stop screw.
