Description

Low center of gravity easily starts walker tractor

Technical field:

The invention belongs to a kind of field machine, be specifically related to a kind of low center of gravity and easily start walker tractor.

Background technology:

In China, present farming power machine mainly contains large, medium and small four-wheeled tractor and walker tractor, the turn radius of four-wheeled tractor is large, turn to dumb, to the edge of a field repeat roll serious, when the plot hour, turn to the time that enters the subsequent job position sometimes also long than the time of actual farming at the edge of a field.Between the road in mountain area, terraced fields plot, mountain area and the plot to be connected the highway section gradient large, rugged and rough, four-wheeled tractor can not be walked on these highway sections smoothly, therefore can not the large tracts of land place in operation in the mountain area.Walker tractor is turned flexibly, the situation that can adapt to preferably the plot, mountain area, although its being connected on the highway section and can not ownly walking between the road in a lot of mountain areas and terraced fields plot, mountain area and plot, but its small volume, other vehicles drive of usefulness that can be more convenient are carried out operation in ground, so walker tractor is the topmost tillage machinery in present mountain area.Its shortcoming is that deceleration and stopping performance is relatively poor, and it is not bery safe to walk.Center-of-gravity position is higher, less stable, when carrying out operation, slightly acclive plot tumbles especially easily, in this case, except people of need drives, also specially need a people to push away or hold to prevent from tumbling with rope from eminence from lower, labour intensity is very large, it is a lot of that the relatively poor people of muscle power uses difficulty, and efficient is very low affects production.The type that power is larger starts effort, in cultivating procedure, sometimes occurs to stop working, and needs two people to shake together and can start, and uses very inconvenient.

Summary of the invention:

For present farming power machine in the relatively poor situation of mountain area result of use, the invention provides a kind of start laborsaving, turn to flexibly, center-of-gravity position is low, have good stability, drive light and flexible, can steadily draw the low center of gravity that multiple agricultural machinery and implement carry out operation easily starts walker tractor.
