In crops growing in rows, the roots of weeds are cut with the hand wheel hoe; they are sometimes also used to break the crust so that a better air circulation is created and to counteract the capillary effect - and thus the drying out.
The hand wheel hoe usually consists of two metal wheels (diam. Approx. 35 cm), each with a rod on the axle that keeps a metal plate, just behind the wheel, at the correct height. Both trapezoidal plates, connected by a bracket, are provided with 2-3 slots into which the oblique knives or hoes can be screwed to the desired width. The whole is pushed in front of you by means of two wooden arms (approx. 130 cm). There are also hand wheel hoes with one wheel with which you can hoe between two rows of plants, as opposed to the model with two wheels, which works on both sides of one row of plants. Nowadays there is a model with a rubber wheel (approx. Diam. 25-60 cm) where the hoes can be replaced by the blade of a hand ridger or hand cultivator (1). [MOT]
