Abstract

PURPOSE:To raise and simultaneously cut lawn grasses trampled down by front wheels with the backward rotating phase sections of cutting blades. CONSTITUTION:In a lawn grass-cutting machine having a mower 6 between the front and rear wheels 1, 2 of a traveling frame thereof, the mover 6 having plural cutting blades 8 each rotated on a vertical shaft X in parallel in the lateral direction, the mover 6 is constituted on the basis of the traveling frame so that the backward rotating phase sections A of cutting blades are placed on the passage marks of the front wheels.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lawnmower having a mower between front and rear wheels.

[0002]

2. Description of the Related Art As a conventional lawn mower of this type,
As shown in FIG. 5, the forward facing phase portion B of the cutting blade 8 was disposed at the passage mark of the front wheel 1.

[0003]

In the lawnmower having the mower between the front and rear wheels as described above, the lawn is stepped forward at the trail of the front wheels. You will have to mow the lawn. Therefore, there is a problem that the trail of the front wheels is mowed and it is cut a little higher, and the finish is poor and streaking easily occurs. An object of the present invention is to eliminate the above-mentioned drawbacks and improve the finish after lawn mowing.

[0004]

A feature of the present invention is a lawnmower having a mower having a plurality of cutting blades rotatably driven about a vertical axis arranged side by side between front and rear wheels of a traveling machine body. The specification of the mower for the traveling machine body is set so that the rearward rotation phase portion of the cutting blade is located at the passing trace of the front wheels.

[0005]

According to the above construction, the lawn which has fallen forward of the passing trace of the front wheels is prevented from mowing by setting the mower specifications for the machine so that it is located in the rearward rotation phase portion of the cutting blade. Reverse cutting with a triggering effect.

[0006]

According to the present invention, therefore, even grass that has fallen forward on the trail of the front wheels is subjected to reverse cutting with a raising action, so that streak-like residue is unlikely to occur and the finish is clean. It was

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a riding lawn mower will be described below with reference to the drawings. FIG. 3 shows a riding lawn mower according to the present invention. This lawnmower is configured such that an engine 4 is mounted on a front portion of a traveling machine body 3 supported by front wheels 1 and rear wheels 2, and a mower 6 is provided at a lower center portion via a link mechanism 5.

As shown in FIG. 1, the mower 6 has three cutting blades 8 which are rotatably driven about the longitudinal axis X in a cutting blade housing which also serves as a frame. This lawnmower has one front wheel
The rearward rotation phase portion A (reverse cutting portion) of the cutting blade 8 is arranged at the passage mark of. For this reason, the grass is stepped down by the front wheels, and even grass that has fallen forward is raised by reverse cutting, which makes it difficult to leave streak-like residue and makes the finish clean.

Further, as shown in FIG. 2, a traveling speed regulation means C is provided by the grass height sensor 9 for regulating the limit of depression of the speed change pedal 11 of the continuously variable transmission 10 toward the forward side so as to travel at a low speed when the grass is long. is there. Reference numeral 12 is a controller, and 13 is a forward / reverse rotation motor.

[Other Embodiments] As shown in FIG. 4, even in the mower 6 of the two cutting blades 8, the rearward rotation phase portion A may be arranged at the passage mark of the front wheel, or three blades. The same applies to the lawnmower equipped with the mower 6 having the cutting blade 8 therein.

Further, the present invention can be applied not only to the riding type lawnmower but also to a walking type lawnmower having a mower equipped with a plurality of cutting blades arranged side by side between front and rear wheels.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
