The present invention relates to a work machine mounted using a connector mounted on the upper and lower links at the rear of the tractor, and more particularly, when the work machine is connected to the front of the work machine frame, the front is high and the rear end is low, so that the front is connected. It can be easily compensated for horizontal connection, and relates to a tractor workbench frame that can be easily returned to its original position by removing the work from the tractor.

In general, there are several kinds of tractor work machines such as plows, harrows, rotary, etc., which are mounted on the upper and lower links of the tractor, or mounted on the upper and lower links and mounted on the coupler to perform a predetermined operation.

When the work machine is connected to the upper and lower links of the tractor, it is necessary to carry out the connection work in a pair of two people, in brief, one person sits in the driver's seat and the other one stands at the rear of the tractor to signal each other. The driver sitting in the driver's seat while exchanging exchanges by operating the hydraulic device to lift the lower link to connect to the upper and lower connecting means of the work machine can perform a smooth connection.

Working with the tractor often occurs alternately attaching / detaching the work machine depending on the purpose of the work, which takes about 20-30 minutes or more to disconnect the work machine connected to the tractor and connect other work machines. There was a dissolution.

This improved end is equipped with a separate connector on the upper and lower links of the tractor, and then by using the connector to hook up the upper connection means provided at the tip of the work machine, the lower connection means is automatically caught so that the attachment and detachment of the work machine is easy. I'm doing it.

Various techniques for connecting and disconnecting a work machine using the aforementioned connector, that is, detaching and attaching, have been proposed. Among them, three or four dogs will be described.
