Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a riding mower that cuts grass such as lawns with a mower mounted on the lower abdomen of a vehicle body and collects the grass in a grass collecting container.

<Prior art> Riding mowers, which are equipped with a mower between the front and rear wheels in the lower abdomen of the vehicle body and which collects grass cut by the mower through a duct into a grass collecting container, have already been used for mowing lawns. It is used for work etc.

In this type of riding mower, the grass collection container has conventionally been installed at the rear or rear-side of the vehicle body, and it is not originally installed on the vehicle body itself (it is not installed separately). Most of them were of the form.

<Problems to be solved by the invention> In the case where the grass collection container is separately installed at the rear of the vehicle body, an additional attachment mechanism must be provided for this purpose, and the grass collection container is placed far behind the rear wheels. Because of the protrusion, the overall length in the front and back direction becomes large, and when the grass collection container is included, the product becomes very large. In addition, the weight of the grass collection container varies greatly depending on the amount of grass clippings inside, so due to the design,
It was difficult to balance the weight between the front and rear of the vehicle, making it dangerous when working on slopes.

On the other hand, with a grass collection container installed on one side of the rear of the vehicle,
Since the grass collection container protrudes laterally, it is difficult to work near obstacles, and as the yield of grass clippings increases, there are problems such as overturning, and the capacity is limited.

The present invention provides a riding mower that can solve these conventional problems.

Means for Solving the Problems> As a means for solving the above problems, the present invention provides a mower 9 between the front and rear wheels 2. In a riding mower equipped with a grass collection container 20 for collecting grass clippings via a duct 17, the grass collection container 20 is provided on the vehicle body 1 on a front axle 4 that supports the front wheels 2, and a rear axle 6 that supports the rear wheels 3. The vehicle body 1 is provided with an engine 31 for driving wheels and a mower, and a control device 37 and a seat 39 are provided on the vehicle body 1 between the grass collecting container 20 and the engine 31.

Function> The grass cut by mower 9 is transferred to duct 17 and chute 1.

Next, the operation of the above configuration will be explained. When mowing a lawn or the like, the mower 9 is placed on the ground and runs while rotating the cutter blade 12 around the vertical axis 11.

When the cutter blade 12 rotates, it cuts the grass, etc., and the cut grass is collected toward the passage 16 by the wind generated by the wind raising part 15, and the duct 17 and the chute 19 are moved along with the air flow. After that, it is sent into the grass collecting container 20. On the other hand, the air sent into the grass collection container 20 is removed by a screen 27 and then exhausted to the outside through an air outlet 28. Therefore, the grass collection container 2
Only grass clippings accumulate in the 0, and can be collected following mowing.

As the amount of grass clippings in the grass container 20 increases, the weight on the grass container 20 side increases accordingly, but since the grass container 20 is on the front axle 4, the weight of the front and rear of the vehicle body increases due to the increase in the amount of grass clippings. The balance does not change significantly during work,
It can also prevent falls when working on slopes.
