Abstract: The hydrostatic control system for an articulate loader provides an improved method for controlling the output of a hydrostatic drive unit for a front end loader, with cooperative connecting means disposed between a pair of axially aligned drive pumps to provide selective output of one or both pumps as dictated by operation of the control mechanism.

Abstract: A pair of connection devices serve as the upper connection between a traction vehicle such as a skid steer loader and an accessory apparatus such as a backhoe. Each connection device includes an anchor element including an anchor element outer end extending from the traction vehicle towards the accessory apparatus and a channel element including a channel element outer end extending from the traction vehicle and towards the accessory apparatus. The anchor element outer end and the channel element outer end have a selectively engaged position for connecting the accessory apparatus to the traction vehicle. A sleeve member is slidably disposed over and operatively connected to the channel element for movement thereon. The sleeve member has a surface adapted for selective locking contact with at least one of the outer element ends for retaining the element ends in an engaged position.

Abstract: A signal actuating device is provided for vehicles of the skid-steer type. The actuating device includes a summing bar that mechanically sums the positions of two manual control bars and that actuates a switch to warn pedestrians when the vehicle is backing up or doing other maneuvers that are potentially dangerous to pedestrians.

Abstract: A skid steer loader comprising an improved loader main frame and including an operator's compartment designed to present a low profile vehicle particularly suitable for low clearance applications. The loader main frame includes a center compartment partially defined by a pair of longitudinally extending, laterally spaced side beams. The engine for the vehicle is mounted at the rear of the center compartment and is acoustically enclosed by structural elements of the frame. A seat pan mounted on the side beams overlies the engine and transmission and separates the operator compartment from the center compartment. At a forward end of the center compartment an elongated transmission case forms a partial bottom wall and also encloses the chain and sprocket drive system of the vehicle. The side walls of the transmission case are displaced from the side walls of the frame, enabling the operator to straddle the case, thus reducing height requirements for both the operator compartment and the overall vehicle.

Abstract: Provided in the hydraulic system for a skid-steer loader is a porting block controlling flow of hydraulic fluid to the driving portion of the hydraulic system. The porting block directs fluid flow to the hydrostatic pumps actuating hydrostatic drivng motors associated with the drive mechanism of a skid-steer loader. Provided within the porting block is a filter for hydraulic fluid as well as a "cold weather" by-pass for hydraulic fluid.
