Abstract

This research was carried out in order to develop a new sad cutting mechanism to cutt grass in plugs used for transplanting operation.
This was required to developing a traditional cutting mechanism, which is cutting the sod in slide rolls has 46 cm width.
The cutting knife is attached with some other perpendicular at 88 mm apart the cutting mechanism cuts and divided roll more smaller. The cutting is done in the two perpendicular direction to obtain slide plugs with 88x88mm in dimension.
The cutting mechanism was made from high carbon steel.
The research was study the factor affecting the cutting mechanism as:
depth of cut, forward speed and edge, for three sod varieties, moisture content and knif  cost operation on the quality of cut.
The results obtain:
The optimum forward speed was 22m/min gave the best quality at cutting depth of 4 cm. The cutting quality was highly affected with the seeding edge and the best one was 90 days at 9% moisture content. The productivity was about 0.12 fed/h.
