The spiked chain harrow support for hoes is used to support the harrow’ seven springs that hoe the soil. The support is inserted in a single-wheel hoe and with a two-wheel hoe. It can also be inserted in the second tool support.
These screwed, fine or heavy prongs provide different combinations on the support:
The middle prong can be removed to avoid working on the row when the harrow is used on a two-wheel hoe
A spring is installed in the middle to lightly work on the row and three heavy springs are put on for working between rows
