1, driver's seat 9 second lines of a couplet are connected to 2 floating buffer devices, constitute with the sliding pin 30 of supporting leg 10 by the spring base 32 that groove is arranged, spring 31, supporting leg 10, connection spring base 32, and a supporting leg 10 can move up and down in spring base 32;

2, socket connects the supporting

seat

23 and 22 of supporting leg 10;

Solid shafting 28 and hollow shaft 25 that 3, groove is axially arranged, an end of axle connects with tail wheel, and the other end is socketed in respectively in supporting

seat

22 and 23 and with screw or bolt 27 and 26 and fixes, and solid shafting 28 can be inserted in the hollow shaft 25.

The utility model has following characteristics compared to existing technology:

Comfortable, safety is operated in the vibration of jolting when 1, the buffer unit below the driver's seat has reduced operation;

2, solid shafting can be inserted in hollow shaft, and two rear tracks can be done flexible the adjustment arbitrarily, can be used in fritter terraced fields, mountain region operation, can climb bigger hillside fields, walk narrow, narrow rugged road;

3, volume is little, in light weight, simple in structure, easy to use, reasonable in design, layout is desirable, cost is low.

Fig. 1 is an overall structure installation diagram of the present utility model;

Fig. 2 is the right TV structure schematic diagram of Fig. 1 tail part.

Among the figure: 1～engine, 2～small belt pulley, 3～belt, 4～duplex belt pulley, 5～rotating shaft, 6～handgrip of switch arranged, 7～frame, 8～adjustment screw rod, 9～driver's seat, 10～supporting leg, 11～tail wheel, 12～foot-operated, 13～farm implements, 14～driving wheel, 15～driving shaft, 16～big belt pulley, 17～belt, 18～bracing frame, 19～power transmission shaft, 20～power installing rack, 21～set bolt, 22,23～supporting seat, 24,29～nut, 25～hollow shaft, 26,27～holding screw, 28～solid shafting, 30～sliding pin, 31～spring, 32～spring base.
