Description

Walking wheel adjustment mechanism and plough machine a little Technical Field The utility model relates to the technical field of agricultural machinery, in particular to a travelling wheel adjusting mechanism and a mini-tiller. Background The mini-tiller comprises a machine body, a tiller blade arranged on the machine body, travelling wheels and a driving device for driving the tiller blade to rotate. In the non-cultivation state, in order to facilitate the pushing of the mini-tiller to walk and reduce the collision risk of the tiller blade and the ground during the pushing of the mini-tiller to walk, the lowest position of the travelling wheel is usually lower than or kept level with the lowest position of the tiller blade.
