Abstract
A yielding mount assembly connecting a movable arm to a support. The arm is adapted to be attached to a number of structures including an earthworking tool, a rotary hoe wheel, a belt tightener roller, and a wheel supporting a vehicle. The mount assembly has a first member clamped onto the support with a U-bolt. A second member is pivoted on the first member and connected to the arm. A split ring spring mounted on the first and second members holds the arm in a first position. The arm is movable from the first position to a second position against the biasing force of the split ring spring. Expansion of the split ring spring in response to pivotal movement of the arm decreases the spring torque arm so that the biasing force applied to the arm is maintained substantially constant during movement of the arm.
