DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] Next, in conjunction with Figure 1-2 the general chassis of the agricultural robot in the embodiment of the present utility model will be described. Among them, a general chassis for an agricultural robot includes a chassis. Above the front part of the chassis 1, a hydraulic component 5 is provided. On the front side of the chassis 1, a diagonal pull rod assembly 18 is provided. The front end of the hydraulic component 5 is connected to a rear attachment connecting piece 11. The rear attachment connecting piece 11 includes a support seat 12. At the rear side of the support seat 12, a plug 8 is provided. The support seat 12 is fixed on the hydraulic component 5 through the plug 8. Below the front side of the support seat 12, an oil cylinder 10 is provided. Above the front side of the support seat 12, a three-point hitch support 9 is provided.
