Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tractor mower collector in which turf grass to be mowed and collected by a mower attached to a tractor is stored in a collector. By attempting to reduce the clogging of turfgrass by transmitting the turfgrass into the blower and starting reaping with the conveyance force of the blower being applied.

2. Description of the Related Art In a tractor mower in which a mower is attached to the front or abdomen of a tractor and a collector is attached to the rear of the tractor, the power take-off between the mower and the blower of the collector is taken out. Interlocking by the device is often performed by independent operation, so if the mower is driven and then the blower is driven, the lawn grass will be cut and transported at the start of cutting, and then the blower will be driven and carried into the collector. Therefore, the grass is likely to be clogged during transportation. The present invention eliminates such a defect.

[0003]

According to the present invention, a mower 1 and a collector 2 for receiving and storing a lawn grass cut by the mower 1 by a blower 13 are attached to a vehicle body 7, and the mower 1 of the mower 1 is installed. The tractor mower collector is provided with a check device 48 so that the transmission can be performed by the operation of turning on the transmission of the blower 13.

[0004]

The functions and effects of the invention: The mower 1 and the collector 2 are mounted on the tractor body 7 so that the blades of the mower 1 and the transfer blower 13 to the collector 2 can be transmitted from the power take-off device. When the transmission of the blower 13 is turned on and off, the blower 13 is driven from the power take-off device, and this operation enables the transmission of the mower 1 to be turned on and off by the restraint device 48. You can make a transmission.

Therefore, even if the mower 1 is transmitted and the mowing is immediately started, the blower 13 has already been transmitted. Therefore, the conveying wind pressure is high in the conveying passage extending from the mower 1 to the collector 2. As a result, there is less clogging of grass during transportation. On the contrary, even if the transmission input operation of the mower 1 is accidentally performed before the transmission input operation of the blower 13, the restraint device 48 cannot drive the mower 1 for safety.
