Embodiment: the utility model is described in further detail below in conjunction with specific embodiment:

In Fig. 1～4: engine 1, case lid 23 are fixed on the vehicle frame 3, fixing reduction box 12 below vehicle frame 3, and this case is formed by connecting by bolt by forward and backward two parts.Front axle 6, rear axle 15 are installed in the forward and backward part of reduction box 12 respectively, turn over the two ends that plough device, wheel 14 are separately fixed at front axle 6 and rear axle 15.The belt pulley 2 that is fixed on the engine 1 drives the clutch 19 that is fixed on the driving shaft 20, is installed in the driving shaft 20 on the case lid 23 and the driving gear 26 that is fixed on this rotates by belt 21.With the driven gear 27 of this gears engaged by be installed in the driven shaft 22 on the case lid 23 and be installed in reduction box 12 and case lid 23 in reduction gearing mechanism drive front axle 6, rear axle 15 rotates, and final driven wheel 14 and turn over the plough device and rotate.

Described reduction gearing mechanism is by the gear 28, the gap bridge I gear 29 that are separately fixed on driven shaft 22, the gap bridge I axle 4, and the front gear 30, gap bridge II gear 31, gap bridge III gear 32, gap bridge IV gear 24, the backgear 25 that are separately fixed on front axle 6, gap bridge II axle 11, gap bridge III axle 18, gap bridge IV axle 13, the rear axle 15 are formed; Driven shaft 22, gap bridge I axle 4 are installed on the case lid 23, and front axle 6 is installed in the first half of reduction box 12, and gap bridge II axle 11, gap bridge III axle 18, gap bridge IV axle 13, rear axle 15 are installed in the latter half of reduction box 12.Said gear meshes in proper order.
