It also chops up unwanted weeds or crop residues. It is tractor drive tillage implement is supported by either a three-point lift or hydraulically by wheels. The large ones have side sections that can be raised vertically or that fold up to allow easier road transport or to provide better storage configurations. Depending upon the disc arrangements, disc harrows are divided into two classes: a) Single action and b) Double action. Single action disc harrowIt is a special design disc harrow with two gangs placed end to end, which throws the soil in opposite directions. The discs are arranged in such a way that the right side gang throws the soil towards the right and the left side gang throws the soil towards the left. Double action disc harrowSpecially designed disk harrow that consists of two or more gangs, during which a group of 1 or two gangs follows behind the set of the opposite one or two, arranged in such a way that the front and back gangs throw the soil in opposite directions and it generally covers the width starting from 5 to 15 ft. Thus the whole field is worked twice on each trip.
It may be of two types: a) Tandem and b) Off-set. a) Tandem disk harrow it's a disc harrow comprising of 4 gangs during which each gang are often angled within the other way b) Off-set disk harrow it's a disk harrow with two gangs in tandem, capable of being offset to either side of the center-line of pull. Two gangs are fitted one behind the opposite. The width covered by these sorts of harrows ranges from 4 to 30 ft. The soil is thrown in both directions because discs of both gangs face in opposite directions. It travels left or right of the tractor. the road of pull isn't within the middle, that's why it's called off-set disk harrow. the off-set disk harrow is predicated on the essential principle that side thrust against the front gang is opposed by the side thrust of the rear gang. Hence the gangs are arranged at suitable angles in order that both thrusts are counterbalanced with one another.
