Description

[Detailed Description of the Invention] The present invention relates to an engine-driven walk-behind mower, and particularly to a mower suitable for cutting weeds in orchards.

In an orchard, such as an apple orchard, branches hang down from both sides between the rows of trees, and there are many places under which a person cannot stand and pass. Therefore, with a lawn mower in which the rotary blade is located only in a position close to the operator's direction of movement, mowing weeds in such farmland is troublesome, inefficient, and tiring.

In view of the above points, the present invention is a new mower that allows the operator to easily and efficiently cut the grass between the rows of fruit trees on the side while walking in a standing position next to the fruit trees. The purpose is to provide

To explain based on the embodiment shown in the drawings, a substantially U-shaped operating handle 3 is attached to a fuselage 1 equipped with a driving engine 2, and the substantially center line X of the handle 3 is
- A first vertical knife shaft 5 is arranged above and in front of Gear boxes 6 and 61 are arranged on the axis of the vertical knife shaft 5.51, both gear boxes are connected by a tube 7, and the gear box 6 on the first vertical knife axis is attached to the machine body 1. The driven horizontal shaft 12 is passed through the gear box 6, connection box 7, and gear box 61, and the horizontal shaft 12 is interlocked with each vertical knife shaft 5, 51 by bevel gears 13, 14. A blade mount 17 is provided at the lower end, a blade 18 is attached to a receiving surface 17a formed by bending its periphery downward, and a common safety cover 19 is attached to the machine body 1 and placed above the double-edged blade mount 17. , is a mower in which a stabilizing wheel 9 is provided on an arm 8 protruding from a connecting pipe 12 in front of a substantially central portion between both vertical blade shafts 5 and 51.

Note that 4 and 4a in the figure are wheels, and the wheel 4a on the side of the rotary cutter that projects laterally may have an extended axle for stability. Power is transmitted from a power output shaft 10 of the engine 2 to a horizontal shaft 12 by a transmission mechanism 11 such as a belt or chain, and from the horizontal shaft 12, a transmission mechanism 15 drives a wheel shaft via a transmission 16. The left and right blades 18 are arranged in a staggered manner so as not to hit each other during rotation.
20 is a rubber cover lowered to the side of the safety cover 19.

The mower of the present invention rotates the handle 3 while rotating the cutting blade 18 in the direction of the arrow in the direction of discharging the grass clippings.
The worker moves forward by operating the fruit tree, and since one of the rotating blades A is located on the center line X-X of the handle 3, that is, on the line in which the worker is moving, the worker stands next to the fruit tree. You can mow the grass near the base of the fruit tree in this position. Since the other rotary blade B is located on the side in the direction in which the worker is moving, it is possible to efficiently cut weeds between rows of trees with hanging branches that make it difficult for people to pass. In this case, the stabilizing wheel 9 and the running wheels 4 and 4a make the rotary cutter B stable even if it is biased to one side.
