The hoe tines are set so as to hoe between the crop rows, and to move the soil behind the tractor and hoe wheels. The latter take the weight of the two operators sitting on the two seats provided. The arms, each bearing its own hoe, can be moved laterally. Each arm is pivotal on a spacer fixed to the frame by a pin which has spacers allowing adjustment between the pairs of arms.</p> |
