The lower rotation connection member 123 is configured as a pair and can rotatably connect the vehicle body B and the seating frame 111 of the tractor T up and down, respectively.

However, the lower rotation connection member 123 is a tractor such that the distance between the pair formed by the pair is gradually reduced from the tractor T to the frame 100 side in order to strengthen the connection state by minimizing shaking when the frame 100 is raised and lowered. (T) can be connected rotatably up and down the middle of the rear lower middle and both sides of the seating frame 111, respectively.

That is, one of the lower rotation connection members 123 has both ends rotatably connected up and down to the lower middle of the rear side of the vehicle body B of the tractor T and the left side of the seating frame 111, and the other end has both ends of the tractor (T).

To this end, the operation means 220 includes a driving button that allows rotational power to be withdrawn from the power take-off shaft P of the tractor T in the forward direction and the power take-off shaft P of the tractor T, as shown in FIGS. 1 and 3 . ), a reverse drive button for allowing rotational power to be withdrawn from the reverse direction and a stop button for preventing rotational power from being drawn from the power take-off shaft (P) of the tractor (T). It may be composed of an accelerator lever 222 that increases the rotational speed of the rotational power drawn out from the power take-off shaft (P) of the.

Here, the operation switch 221 may be connected to an operation switch previously installed on the tractor T. And the accelerator lever 222 may be connected to the accelerator lever previously installed in the tractor (T).

And when only the forward rotational power is withdrawn from the power take-off shaft P of the tractor T, the reverse drive button may operate the driving motor of the reverse driving means for the reverse rotational motion of the rotational drive shaft 150 .

On the other hand, the lifting switch for lifting and driving the lifting link arm L of the tractor T may not be separately provided in the frame 110 . That is, since the frame 100 is lifted when the tractor T is moved, the frame 110 can be raised and lowered by manipulating the lift switch previously installed on the driver's seat of the tractor T.

The above-described embodiments are merely exemplary, and those of ordinary skill in the art can variously modified other embodiments therefrom.

Therefore, the true technical protection scope of the present invention should include not only the above embodiments but also other variously modified embodiments by the technical spirit of the invention described in the claims below.
