Field manage machine with air breathing filtering system

The invention discloses a field management machine with an air breathing filtering system. The field management machine comprises a stander, wherein the upper side of the rear part of the stander is connected with a pushing beam and a pushing handle; an engine is mounted on the stander; a first-stage breathing filtering mechanism is arranged on the pushing handle and is connected with a middle air guide mechanism positioned in the pushing beam; the middle air guide mechanism is connected with a second-stage breathing filtering mechanism; the second-stage breathing filtering mechanism is connected with the engine; a power output shaft of the engine is connected with an overrun clutch; a front dustproof fender mechanism is arranged at the front part of the overrun clutch; an output shaft of the overrun clutch is connected with a speed change box; an upper dustproof fender mechanism is arranged at the upper part of the speed change box. According to the field management machine, the working speed is effectively increased, the power output is sufficient, and the field management machine is small and flexible, can effectively filter air and protect power equipment and can be effectively prevented from being stuck with mud, thus guaranteeing the safety of workers.
