BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work vehicle for a turf management machine used for growing and managing turf on a golf course or the like.

[0002]

2. Description of the Related Art Generally, grass management work is performed in the early spring, fertilizer is applied next, and water is sprayed from the end of the rainy season to the summer, and the chemicals are controlled against diseases and harmful insects of the grass. Mow lawn and sweeper work in summer.

Conventionally, many such operations have been carried out by a sand spreader for applying sand, a fertilizer sprayer for sprinkling powdered or granular fertilizer, a sprinkler, a chemical sprayer for spraying a chemical solution, a lawn mower, This is done by a turf management machine such as a sweeper that collects the cut grass.

[0004]

Many of the above grass management machines are not used throughout the year and are stored for most of their time. Nevertheless, some of the turf management machines, such as sweepers, have self-propelled parts, and these self-propelled parts are wasted when stored for a long period of time.

The present invention has been made in order to solve the above-mentioned problems, and enables various turf management machines to be used by one self-propelled work vehicle, so that the turf management machines can be self-propelled. An object is to obtain a work vehicle for a turf management machine that eliminates the need for parts and eliminates waste when storing the turf management machine.

[0006]

A work vehicle for a turf management machine according to the present invention is provided with a pedestal on the chassis of a self-propelled work vehicle, and various turf management machines have a mounting frame common to all machines. Deployed,
Each mounting frame enables various turf management machines to be mounted on the cradle by replacing them, and each of the various turf management machines can be connected to the hydraulic unit of the self-propelled work vehicle as a hydraulic drive system. It was done like this.

[0007]

In the present invention, the necessary grass management machines can be remounted and mounted on the pedestal of the self-propelled work vehicle by the mounting frame, so that various kinds of grass management machines can be set separately on the mounting frame. , The self-propelled part is unnecessary for various turf management machines.
