A window latch mechanism for use on cab structures associated with agricultural and construction machinery having improved resistance against breakage. The resistance against breakage is accomplished by constructing the window latch from a resilient material shaped in a forked configuration having a first and second tine. The latches are oriented such that the tines maintain a general vertical orientation. The window latch is pivotally connected to one tine, and the remaining tine is supported by the window slide. Vertical forces imparted to the window are reflected onto the latch and cause the resilient latch tines to move relative to each other, thereby allowing the tines to absorb the forces. The window latch is associated with a window slide having one longitudinal surface which cooperates with the sides of the window to permit vertical location of the window, and another longitudinal side of the slide includes a plurality of notches whereby the latch mechanism can be engaged in the notched to permit placement of the window in any number of vertical positions.

Cushioned latch

A window latch that includes a handle portion secured to the window and a generally U-shaped latch member that is secured to the frame. The U-shaped latch member defines a projection in engagement with the handle to retain the window in the closed position. To open the latch, the legs of the U are moved toward each other to disengage the projection from the handle to permit the window to be moved to the open position.

Latch assembly

A two position seat assembly is disclosed for use on a material handling vehicle. The seat assembly has a seat back section which pivots to be used as a back rest or as an elevated seat for facing the rear of the vehicle. This permits the vehicle operator to face forward to operate forward mounted equipment or to face backward to operate rearward mounted equipment.

An implement side shift assembly is disclosed for laterally shifting an earth-working implement relative to a tractor or the like. The side shift mechanism permits various implement attachments to be mounted on one common side shift frame. The side shift assembly includes a frame assembly having laterally extending upper and lower slide rails. An implement support bracket mounts the implement to the slide rails for lateral movement. A slide plate is slidably mounted between the slide rails for lateral movement, and a piston-cylinder is connected between the frame assembly and slide plate to move the slide plate laterally. A latching mechanism selectively connects the slide plate to the implement support bracket at one of a plurality of connecting points on the implement support bracket. One of the points of connection between the slide plate and implement support bracket permits lateral shifting of the implement by the piston-cylinder from the center of the frame assembly to the left and back to center while another point of connection permits shifting from the center of the frame assembly to the right and back to center. The side shift assembly permits the implement attachment to be moved laterally twice as far as the piston stroke. The latching mechanism for latching the slide plate to the implement support bracket is accessible to the operator and is capable of being unlatched regardless of the position of the implement or automatically tripped for relatching the slide plate to the implement support bracket as may be desired.

An improved remote control assembly for mechanically controlling the operation of a hydrostatic pump which may be used to power the attachments on a tractor-like vehicle. The assembly includes a first control unit positioned at a first remote location on the tractor and a second control unit positioned at a separate and distinct remote location. The assembly includes a control arm secured to a pump control element whose rotation controls the pump operation. A pivot arm is pivotally carried by the control arm and has a first control cable from the first control unit connected to one end and a second control cable from the second control unit connected to the opposite end. The assembly is configured such that when the first control unit is locked in a neutral position, the second control unit is operable to rotate the pivot member about its first end to operate the control arm and when the second control unit is locked in a neutral position, the first control unit is operable to rotate the pivot arm about the opposite end to operate the control arm thereby enabling the pump to be selectively controlled from either of the two remote locations.

The disclosed Power Shift Mechanism is adapted to laterally shift an earth working implement, such as a vertical plow, relative to a tractor or the like. In the disclosed embodiment, the plow is mounted on a slide bracket and the bracket is slideably mounted on a support frame. The shift mechanism includes a fluid operated piston-cylinder connected between the frame and a pivot link pivotally connected to the slide bracket. The pivot link may be rotated by the piston-cylinder to either of two positions and locked in place by releasable connectors. The piston-cylinder will then rotatably shift the pivot link or laterally shift the bracket and the earth working implement. The shift mechanism thus increases the effective stroke of the piston-cylinder and reduces the power requirements of the shift mechanism.

An automatic reset plow assembly includes a plow frame drawn by an agricultural vehicle. A plow standard is pivotally connected to the underside of the frame to enable the plow share to pivot backwardly and upwardly upon engaging an obstruction in the soil. The plow standard is resiliently biased downwardly by a toggle link assembly having one link pivotally connected to the plow standard and a second link pivoted to the frame. The other ends of the two links are pivotally connected together and to a slide element to form the elbow of the toggle link. The slide element is slideably received along a guide member which is also pivotally mounted to the frame. A compression spring surrounds the guide and resiliently biases the slide element and toggle links to maintain the plow standard in a normally downwardly pivoted plowing position. Upon encountering an obstruction, the plow pivots rearwardly and collapses the toggle link assembly. After the plow passes the obstruction, the spring returns the toggle link assembly and plow to their normal operative position. A damper assembly is optionally provided at the connection between the frame and second link to reduce shock resulting from the return of the plow from its tripped positioned to its operative plowing position.

A spring bias safety trip mechanism for holding a ground working tool in a fixed position with respect to a support frame is disclosed herein. The spring bias safety trip mechanism consists of a plurality of links that are interconnected in such a manner that the links act as a rigid bar between the frame and standard and collapse when excessive forces are encountered by the standard. The spring biased linkage system is designed to eliminate the need for large springs that must produce sufficient forces equal to the normal forces encountered during the normal earthworking operation.
