Four-way hitch on a tractor by attaching to the engine block (front axle area), the gearbox block (rear axle area), front power lift and rear power lift with attachment option for e.g. a crane

Abstract

Hitch with force-locking attachment of the implement at four different points on a tractor. 1. 3-point front linkage 2. 2-point rear linkage 3. Pinning on the engine block (front axle area) 4. Pinning on the gearbox block (rear axle area)

Description

[0001] Traditionally, trailed implements are attached either to the front or rear power lift. The invention allows the four-point hitch to be connected simultaneously to four positions on the tractor: 1. the front power lift, 2. the rear power lift, 3. the engine block (front axle area), and 4. the transmission block (rear axle area).

[0002] With the front attachment of the four-point hitch (attached to the standard 3-point front linkage), the crossbar is threaded in when rearwardly coupling the tractor. The rear linkages are usually engaged at the attachment points of the crossbar, depending on the model. After raising the crossbar and attaching it to the front, the pins are secured with bolts to the pins on the engine block and transmission block. Pinning with hydraulic sliding pins is considered the most user-friendly option.

[0003] The invention specified in the claims is based on the problem of creating a hitch that can absorb vertical tensile and compressive loads and is removable and restores the ground clearance of the tractor.

[0004] The invention ensures that the force applied by the attachment is distributed across four attachment points. Vertical tensile and compressive forces can be absorbed. Road approval is ensured by the standard 3-point front linkage and 2-point rear linkage. Further requirements for road approval are outside the scope of this document.

[0005] The embodiment of the invention is explained using figures one to five. They show: Fig. 1: Four-way hitch from the front Fig. 2: Quadruple attachment from above Fig. 3: Quadruple hitch from the right Fig. 4: Quadruple attachment in the spatial image Fig. 5: Four-way hitch with tractor from the right Fig. 6: Four-way hitch with tractor from above

[0006] The front attachment (2) is attached to the 3-point front linkage (7) in the usual way. The threading point (8) connects the front attachment (2) to the crossbar (3). The 2-point rear linkage (9) is connected to the crossbar (5) attachment points. The transmission block (4) and engine block (3) pins connect the crossbar (3) to the tractor. Work flow quadruple hitch

[0007] The forces and loads of the device attached to the mounting surface (e.g. crane) are transferred to the tractor via four connection points (see above).
