Abstract

A hitch fitted to the front end of a tractor is operated by hydraulic rams to control the hitch pin and/or the hitch height. These may be operated from within the tractor as may also the safety lock. Other attachments such as pallet forks or front and weights may be used. <IMAGE>

Description

SPECIFICATION Tractor front mounted pick-up hitch This invention relates to a tractor front mounted pick-up hitch.
It is normal for a tractor (particuiarly an agricultural tractor) to be fitted with a fixed or variable height pick-up hitch to the rear. Occasionaly a fixed clevis and pin type hitch is fitted to the front end. This leads to difficulties in parking trailers and trailed machinery particularly in low sheds due to lack of visibility when reversing and manoeuvrability due to the cab.
According to the present invention a hitch is provided at the front of the tractor consisting of a hydraulic ram which runs up and down in a hollow steel section. The ram is operated by a hydraulic spool valve from inside the tractor cab. The other end of the hydraulic ram is fitted with another piece of hollow section which fits inside the first hollow section and supports the hitch assembly. Its position is sensed by a micro-switch or similar and indicated in the cab. This hitch assembly consists of a "V" shaped opening with a hitch pin running down through the centre. Alternatives to the hitch may be fixed. e.g. (a) pallet forks (b) arms to take front end weights. The hitch pin may be operated by (1) mechanical method using spring and chain which comes into operation when main ram is lowered. See Diagram (1). (2) Hydraulic ram control or (3) Solenoid.The position of the hitch would be sensed by a micro-switch or similar and indicated in the cab by a dashboard light.
The ram maybe locked in the up position by a linear actuator operated hook. See Diagram (2). This is sensed by a micro-switch or similar and is indicated in the cab. The hook may alternatively be operated by a hydraulic ram or an electrical solenoid.
The positioning of the trailer hook to the hitch is observed in a mirror fixed to one side of the ram support.
The front mounted hitch is fixed to the front trunion block of the tractor. The design of the brackets will depend on the make and size of tractor.
A typical example is when a tractor driver simply unhitches the trailer from the rear of the tractor and while remaining in the cab re-hitches it to the front by lowering the ram; aligning hitch as seen in morror to the trailer hook; lifting ram and remotely controling the pin insertion; when ram returns to full height initiating locking device and then driving tractor forward to push the trailer into the shed. Putting the machine into the shed this way around will enable him to see exactly where it should be positioned.
