Improvements in the accuracy of control of tractor mounted hoes

, : Improvements in the accuracy of control of tractor mounted hoes. Zemedelska Technika 38(5): 325-330

Methods for improving the accuracy of control of tractor mounted hoes are discussed, in particular, a passive system using a modified hitch design and an active system using crop sensors with an electro-hydraulic control system. Experiments showed that the passive system did improve implement accuracy although it depended on the driver positioning the tractor correctly. The active system was found to reduce crop damage from 5.2 to 1.2% provided that the row was sensed accurately.
