In: Misr Journal of Agricultural Engineering 2018.v.38(1)Summary: This research aimed manufactured and evaluate the developed cultivator unit with modified share suit for vegetables crops inter – row cultivation process, field experiments were carried out on tomato crop planting season 2019 under different operating conditions, at three types of shares used in cultivator unit St (shovel share & Duck leg share & modified share with wings), four inclination angles of soil sliding knife Sa (Sa1=30o & Sa2=35o & Sa3= 40o & Sa4= 45o) and three depths of press wheel Wd (Wd1= 2 & Wd2= 3 and Wd3= 4 cm.). four measurements achieved : weed erasing efficiency (We %) , weed control efficiency (Wc %) , percentage of damaged plants (Dp %) and furrow cross-section profiles, all experimental procedures and measurements were assessed after 30 days from tomato transplanting. The results showed that the highest press wheel depth (Wd3 = 4 cm) with soil sliding knife inclined angle (Sa = 45o) and wing share obtained high erasing efficiency (We=97%) and highest weed control with regular forming furrow profile, on the other hand duck leg share had highest damage plant percentage (Dp = 1.2%)

This research aimed manufactured and evaluate the developed cultivator unit with modified share suit for vegetables crops inter – row cultivation process, field experiments were carried out on tomato crop planting
season 2019 under different operating conditions, at three types of shares used in cultivator unit St (shovel share & Duck leg share & modified share with wings), four inclination angles of soil sliding knife Sa (Sa1=30o & Sa2=35o & Sa3= 40o & Sa4= 45o) and three depths of press wheel Wd (Wd1= 2 & Wd2= 3 and Wd3= 4 cm.). four measurements achieved : weed erasing efficiency (We %) , weed control efficiency (Wc
%) , percentage of damaged plants (Dp %) and furrow cross-section profiles, all experimental procedures and measurements were assessed after 30 days from tomato transplanting. The results showed that the highest press wheel depth (Wd3 = 4 cm) with soil sliding knife inclined
angle (Sa = 45o) and wing share obtained high erasing efficiency (We=97%) and highest weed control with regular forming furrow profile, on the other hand duck leg share had highest damage plant percentage (Dp = 1.2%)
