Abstract

PURPOSE:To enable good side reaping in reaping the circumference of a garden and improve efficiency of reaping operation by providing a guide capable of changing the posture of mower deck on lateral and peripheral wall of the mower deck. CONSTITUTION:In a working type mower attaching an engine on the upper surface of a mower deck equipped with front wheels 12 and rear wheels 15 so that a crank shaft 7 is vertically retained, providing a reaping blade 10 on a working shaft 11 provided side by side so as to protrude in a mower deck 1 and simultaneously providing a handle in the rear, the following constitution is attached: Guides 22 and 22 capable of changing to protruded posture situated outside from the outer faces of front wheels 12 and 12 and rear wheels 15 and 15 and housing posture situated on lateral peripheral walls 2 and 2 are provided on the lateral peripheral walls 2 and 2 of mower deck. In reaping lawn, when circumference of a garden is reaped around, the guides 22 and 22 are changed to protruded posture. Thereby lawn between reaping blade 10 and article surrounding garden is guided by a guides 22 and 22 and cut and good side reaping can be carried out.

Description

[Detailed Description of the Invention] [Field of Application of ρ冫、Near 1.] This invention provides a mower deck for a walk-behind mower. +11 rivers!
Dial with I'l'. , "Shu. Next Technology" Needless to say in Utility Model Application Publication No. 36222/1983, walk-behind mowers are generally connected to the crankshaft in the upper T/7 direction of the engine attached to the 1-1rII of the mower. The outer periphery of the cutting blade provided on the work shaft is covered with the outer peripheral wall of the mower deck with a gap.

[Problem to be solved by the invention]

In the prior art described in Section 12, the meat I1 of the outer peripheral wall of the mower deck
1. The problem is that the total width of the area, its outer circumference, and the gap between the cutting blades is left uncut when cutting edges, so the area to be cut later using a brush cutter, edge trimmer, etc. is large. It was a point.

[Means to solve the problem]

This invention has taken the following technical means to solve the problems mentioned in (5) above. That is, the engine is mounted on the upper surface of the mower deck with the front wheels and rear wheels so that the crankshaft is directed downward, and the cutting blade is installed on the working shaft that is connected to the crankshaft so as to protrude into the mower deck. , in a walk-behind mower with a handle provided in the mower deck width/section, a protruding position located outside the outer surface of +1f +l* and the rear wheel on the lateral outer circumferential wall of the mower deck, and a storage position located on the side of the lateral outer circumferential wall. The configuration includes a guide that allows easy switching.

[Effect]

Grass with a walking mower? When mowing l'I, first when mowing around the garden, switch the guide to an outwardly protruding position and then set this guide up. ! When a walk-behind mower is operated so as to move along objects, fences, fences, and other surrounding objects in the garden, the grass Iλ between the position where the edge of the cutting blade passes and the surrounding objects will be moved along the guide. At the same time, it is guided into the mower deck with f1 inside, cut by the cutting blade, and discharged to the outside. [Effects] This invention provides a guide on the horizontal outer wall of the mower deck that can be switched between a protruding position located outside the outer surface of the Mii rear shaft and a storage position located on the side of the horizontal outer peripheral wall. Therefore, when mowing the lawn 1°X, when mowing around the garden, switch the guide to the protruding position so that the grass between the cutting blade and the garden objects will be guided by the guide and cut. By doing so, it is possible to perform good cutting and increase the efficiency of the cutting work by -1. [Examples] Hereinafter, based on the illustrations, one example of M cutting will be explained. .

First, the configuration will be explained. The drying deck 1 of the walk-behind mower is provided with a ceiling wall 3 at one end of an outer circumferential wall 2 which is circular in plan view, and a ceiling wall 3 (diagonal Ji, city part 4) that is successively higher on the right side of the ceiling wall 3. The engine 6, which is attached to the ceiling wall of the Moadesogi 1, is located at the lower side of the outer circumferential wall.
