Based on the seed to seed spacing within the row for maize crop the reduction mechanism was developed. Generally, recommend spacing for maize is 220 to 260 mm. The speed of the punch wheel was estimated based on the predetermined seed to seed distance of 240 mm for maize crop. To obtained the optimum spacing between consecutive punches, the gear reduction was selected in three stages. The first reduction stage occurred between engine to PTO shaft, second stage between PTO shaft to reduction gear box output shaft and third stage reduction gear box output shaft to punch wheel shaft. Engine speed was maintained at 1000, 1500 and 2000 rpm corresponding PTO speeds were noted and average reduction ratios were calculated at two PTO lever positions as 4.46 and 3.07 respectively. Reduction ratios from PTO shaft to gear box output shaft were obtained as 1.85 and 1.84 at two lever positions. The reduction ratios from gear box output shaft to punch wheel were obtained as 2.41 and 2.42. overall reduction ration from engine speed to Punch wheel shaft at two lever positions were obtained as 19.96 and 13.67. Tractor forward speed was measured in three gear positions by increasing the engine speed from 800 to 2400 rpm. In three gear positions the forward speed increases by increasing the engine speed. In a particular PTO lever position (P1) with the combination of gear selection three different punch spacing were obtained as 16, 24 and 53 cm respectively. In each combination (P1G1, P1G2 and P1G3) even though forward speed increases, there is no significant effect on punch spacings were obtained as 10, 16 and 35 cm respectively. In a particular PTO lever position (P2) with the combination of gear selection three different punch spacing are obtained. In each combination (P2G1, P2G2 and P2G3) even though forward speed increases, there is no significant effect on punch spacing.
