This study consist of two parts. One is development of a self-propelling vinyl remover which was already reported at the previous paper. This is the second part of the study. For the study, an attached vinyl remover was developed. It was consisted of connecting tractor to bucket, removing bucket from tractor, and the process was the tractor's assistance hydraulics. In the case of an attached vinyl remover, the vinyl was twisted 0.5times per 30~85cm length. The bobbin's diameter was 190mm and it's stable travelling speed was 1m/s. The revolution of the remover wheel was 90rpm to maintain the wheel's linear velocity. As seen at performance test at the field which had 950mm ridge intervals and 10 a area, the average working speed was 1m/s and the turning time was 20seconds. Therefore, the working performance was 24.5min/10a. The efficiency of used vinyl remover was 97% and working conditions were good.

Mulching vinyl is used on field crops to reduce herbicides and this causes multiple effects. The mulching vinyl must be collected for the next crop season, but was left alone due to a shortage of labor. The used mulching vinyl that was left alone acted as one of the main sources of environmental pollution on farms. In order to solve these problems, a self-propelling vinyl remover was developed. The self-propelling vinyl remover consists of a travelling part and rotating of remover wheel. Each output device has a 1.5ps engine and a 2.5ps engine. The vinyl was twisted 17~47cm/times length. The bobbin's diameter was 160mm and it's stable travelling speed was 0.5m/s. The revolution of the remover wheel bobbin was 60rpm to maintain the wheel's linear velocity. As seen at performance test at the field which had 950mm ridge intervals and 10a area, the average working speed was 0.56m/s and the turning time was 15seconds. Therefore, the working performance was 40.1min/10a.
