Description

Hand push lawner

The utility model relates to a kind of greening machinery, especially hand push lawn mower.

At present, known hand push lawn mower as the product LM4D of common prosperity society of Aichi, Japan Co., Ltd. hand mower, has seven flying knifes, and complex structure grinds maintenance and is difficult for.

The purpose of this utility model is a kind of hand push lawn mower that provides in order to overcome above-mentioned technical deficiency part.

It is the gravity wheel of gravity with wheel rim weight that the purpose of this utility model is achieved in that on a hand push frame by adorning a pair of, and the gravity wheel wheel face has and the meadow walking adhesion property decorative pattern preferably that adapts; Adopt my patent No.: 92236179.7, the double sickle cutterbar of sheave fork transmission, to improve cutting speed and cutting efficiency, the cutter both sides are by adorning a pair of high gauge wheel that cuts, hang a careless case of collection on the hand push frame, the hand push gravity wheel drives cutter can finish turf-mown and herbage harvesting operation.

Because adopt such scheme, the utility model and prior art are compared, have simple in structurely, operate easy maintenance, the swath broad, efficient is higher; Cost is low; Free of contamination advantage.

The utility model is described in further detail below in conjunction with drawings and Examples.
