Currently, outside farm land of slope land has rapidly increased with development of the off road and on road, etc. The weeds management working has been performed over various areas such as slope land farm land, water read, golf field, outside land of urban and area around house, but it is placed in difficult circumstances because of poor working environment.
As the weeds management working involves many danger, it is necessary to develop the machine for safety and convenience of worker. The weeding machine have been mainly developed and producted concerning the rice paddy and farm field in domestic. so the products which can be work at water road etc is wholly lacking. Therefore, in order to complete smoothly the weeds working over poor and dangerous areas, it is necessary to do develop the arm-type cultivating machine.
Arm-type cultivator is necessary to develop by the standard auto hitch type attatched to existing tractor considering the use of hydrauric system and the movement of the machine. Also, the arm-type cultivator has to develop the system that can efficiently be utilize the midium and large-sized tractors which is most widely used in domestic farm, and that can easely be attach and detach to the standard auto hitch of a general agricultural tractor.
If this system develop, it is expected to create big market because the system give the agricultural producer an advantage can be sell this system not only for farmer of self-management, business farmer but also for the product market which relates with constructive machinery and express highway etc. The 3-P hitch cultivator must be developed with arm-type in order to do smoothly the weeds working at the slope land using the tractor.
Therefore, this study was conducted to developed the arm-type cultivator that can work at not only flat land also slope land. The results of this study could be summarized as follows.
1) Arm-type cultivator are composed to (1) Frame, (2) Boom and boom cylinder, (3) Arm and arm cylinder, (4) Rotary type weeds cultivator for weeds working, (5) Joystick operating the link of arm-type cultivator
2) When the tractor attached the arm-type cultivator drives a off road and on road, the lean of the tractor did not occur for both straight and turning motion.
3) In order to estimate the lateral overturning stability of the tractor installed arm-type cultivator, the stability of the tractor was investigated under condition extend the cultivator to the utmost limit. As a result, the lean and change of the posture for possible to cause the lateral overturning of the tractor did not show.
4) The weeds working conducted in slope land showed satisfactory results in term of the working performance and the safety of worker.
Additional complement research is the reliability experiment and an improvement of the parts. If it is applied tractor, forestry machine, excavator, the market magnification will be possible.
