Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fertilizer applicator for a rice transplanter, which laterally fertilizes paste fertilizer on the side of the seedling planting line during planting work by the rice planter.

[0002]

Conventionally, the unit clutch lever is arranged on the side of the planting part such as the rear surface of the seedling stand, and the fertilizer application stop lever is located on one side of the traveling machine side with respect to the center of the machine. When the unit clutch is disengaged, it is necessary to disengage the corresponding ratchet lever at the same time. However, depending on the line to be turned off, for example, the operator twists the body to the left side of the seat to turn off the unit clutch lever, and then twists the body to the right side of the seat to turn off the fertilizer application lever. It is bothersome and the operability is poor, and there is a risk of erroneous operation.

[0003]
