A fluid pump control for a tractor having a fluid pump controlled by an operator's handle connected to the pump by force-responsive members which do not transmit the pump vibration to the handle. The control is for a tractor transmission driven through a variable displacement pump which inherently develops vibrations. The handle is a pivotally mounted lever and the connections between the handle and the pump are four cables, and two intervening compression springs, all for transmitting the force on the lever to the pump while avoiding transmitting the pump vibrations back to the lever. The springs also are arranged with the cables to automatically return the pump to a neutral position when the operator releases hand force on the lever.

A hand control system for a tractor having several controllable units such as hydraulic and brake units. A tubular member is rotatably mounted about its longitudinal axis and it connects to one of the units for actuating the same, and a member is pivotally mounted on the tubular member and has a handle thereon which connects to a linkage extending partly through the tubular member and connects to another of the units for operating same. The tubular member can be rotated to actuate its connected unit, without requiring actuation of the handle, and, conversely, the handle can be actuated to move its linkage and actuate its connected unit, without moving the tubular member and its unit. Also, another tractor unit, such as a brake, is connected into the system such that when the one member is pivoted upwardly on the tubular member the handle is placed in an inoperative position and the brake is automatically operated, as desired.

A reverse linkage loader bucket arm with an enclosed cylinder assembly and wherein a loader bucket is pivotally mounted on the arm and the cylinder assembly induces the pivotal action. The lift or support arm for the bucket is hollow along its longitudinal axis and the cylinder assembly is mounted within the hollow arm and projects through an open end thereof to pivotally connect with the bucket and the point of pivotal connection is to the side of the pivotal connection of the arm in the bucket away from the bucket. The cylinder fluid lines are also disposed within the hollow boom or lift arm, and thus the cylinder assembly and the lines or hoses are enclosed and thereby protected and arranged for reverse linkage connection relative to the arm and the bucket.

A quick attachment device for a tractor which has lift arms for supporting an implement, such as a loader bucket, lift fork, or the like. The rear side of the implement has two spaced-apart attaching portions in the form of hooks faced toward each other, and an attachment plate is held by the tractor lift arms and the lower edge is first positioned into the lower implement hook and then the plate is slid upwardly until the upper edge is engaged in the implement upper hook. A spring-loaded pin then automatically falls into a hole in the implement to secure the plate relative to the implement and thus attach the implement and plate together. A release cam is attached to the pin for withdrawing the pin and the attachment plate can then be manuevered out of the implement hooks to be removed from the implement when release is desired.
