  In such a reel-type lawn mower, when a roller for brushing up the lawn is arranged between the front roller and the reel cutter, the front roller is arranged at a position protruding forward in order to secure an arrangement space for the roller. There is a need to. However, if the distance between the front roller and the reel cutter is increased, in lawn mowing work such as the ground surface with fine undulation, the ground surface part where the reel cutter is located is higher or lower than the ground surface part where the front roller is located. Differences are likely to occur. As a result, the cutting height of the turf cannot be made constant, and there is a possibility that harmful effects such as galling by the reel cutter will occur.

  Therefore, in order to bring the front roller as close as possible to the reel cutter, it is conceivable to arrange a grooming cutter or the like for stirring the turf in front of the front roller. However, this is not preferable because the grass that has been stirred up by a grooming cutter or the like is brought down again by the subsequent front roller.

  In view of such a point, an object of the present invention is to propose a reel-type lawn mower that can dispose the front roller close to the reel cutter and can reliably scrape the lawn.

  In order to solve the above-mentioned problem, the reel-type lawn mower of the present invention is disposed at the front part of the reel cutter in the lawn mower body, and the reel cutter disposed at the lower part of the lawn mower body, A front roller that defines a cutting height by the reel cutter, and a brush that has a predetermined height and thickness disposed between the front roller and the reel cutter in the lawn mower body. It is characterized by being.

  In the present invention, a brush is placed between the front roller and the reel cutter. Unlike the case of arranging a turf-setting cutter such as a grooming cutter, a plate-like turf-setting brush can be arranged in a narrow space. Therefore, it is only necessary to provide a small gap between the front roller and the reel cutter, which is necessary for the placement of the turf brush, and the front roller and the reel cutter are placed close to each other as if no turf attachment is attached. Can be placed.

  Thus, since the front roller and the reel cutter are arranged close to each other, the lawn can be mowed at the cutting height defined by the front roller, and harmful effects such as grass scuffing by the reel cutter do not occur. In addition, it is possible to reliably rake up the turf that has fallen with the brush on the turf before the reel cutter and mow it with the reel cutter.

  In addition to this, the grass before being cut by the reel cutter is placed on the turf and touches the brush to remove moisture such as dew. When the mowing turf contains a lot of moisture, the mowing turf collects each other and may fall to the ground surface without being collected by the bucket attached to the lawn mower body. Also, grass with moisture may be heavy and may not be easy to handle. Since moisture is removed from the lawn before it is mowed by the brush, it is possible to prevent such harmful effects.

  Here, it is desirable that the lawn brush is attached to the lawn mower body in a state in which the attachment height can be adjusted. Since the turf fall state and the like differ depending on the turf type and the like, it is desirable to be able to adjust how much the hair tip portion of the brush is raised toward the ground surface side.

  For the same reason, it is desirable that the lawn brush is attached to the lawn mower body in a state where the attachment angle in the front-rear direction can be adjusted.

  In the present invention, it is desirable that the turf brush is attached to the lawn mower body so as to be able to swing in the vertical direction about an axis extending in the left-right direction so as to follow the undulation of the ground surface. .

  Generally, the left and right shaft ends of the roller shaft of the front roller are supported by the left and right front roller brackets so that they can rotate, so that they can swing up and down around a fulcrum pin attached to the left and right front roller brackets. The left and right swing brackets are arranged, and the turf brush is bridged between the left and right swing brackets. Thereby, it is possible to make the turf brush swing up and down around the left and right support shafts.

  In this case, a swing adjustment bolt capable of adjusting the swing limit of the swing bracket downward in order to allow the hair tip portion on the lower end side of the brush to be placed on the grass in an appropriate state. It is desirable to have.

  For the same reason, it is desirable to provide a mounting angle adjusting bolt capable of adjusting a mounting angle in the front-rear direction of the turf brush with respect to the swing bracket.

  Further, in order to be able to switch the mounting brush so that the brush can be selectively swung or not mounted, the swinging bracket can be fixed to the roller bracket so as not to swing. It is desirable to have a bolt for dynamic regulation.
