Abstract Translated from Japanese (57)【要約】 (修正有) 【課題】 硬質の圃場において、ロータリ作業機を昇降 自在に装着したトラクタを使用して作業を行う場合、作 業開始時や旋回終了時に作業機を土壌に降下着地すると 回転爪の掘削抵抗による反力を受けてトラクタが前に跳 びだすダッシング現象を防止する。 【解決手段】 エンジン1を搭載する車体の後部にロー タリ作業機を昇降自在に連結可能とし、車体には、実車 速を検出する対地車速センサと、後輪5R・5Rを制動 するブレーキ装置6・6とを設け、エンジンの回転動力 を後輪5R・5Rを駆動する走行系L1、及びロータリ 作業機を駆動する作業機系L2へと分岐するとともに、 それぞれ独立して回転動力を断続するクラッチ機構7, 8を設けたトラクタであって、作業機3を下降したとき に、検出した車速が設定速度を越える時は作業機系の回 転動力を断絶してブレーキ装置を作動させる制御部を設 ける。 (57) [Summary] (Modified) [Problem] When performing work using a tractor equipped with a rotary work machine so as to be able to move up and down in a hard field, the work machine is lowered to the soil at the start of work or at the end of turning. Upon landing, a dashing phenomenon in which the tractor jumps forward due to the reaction force due to the excavation resistance of the rotating claw is prevented. SOLUTION: A rotary work machine can be connected to a rear part of a vehicle body on which an engine 1 is mounted so as to be able to move up and down freely, a vehicle speed sensor for detecting the actual vehicle speed, and a braking device 6 for braking rear wheels 5R. 6 to divide the rotational power of the engine into a traveling system L1 that drives the rear wheels 5R and 5R and a working machine system L2 that drives the rotary working machine. A clutch mechanism 7 for intermittently rotating power independently of each other, A tractor provided with a control unit for cutting off the rotational power of the work implement system and activating the brake device when the detected vehicle speed exceeds a set speed when the work implement is lowered.
