What are the different types of disc harrow?
Disc Harrows typically come in three different types of cutting options – single action, double action and offset models. Single Action Disc Harrows: Single action harrows cut the soil in one direction. Double Action Disc Harrows: Double action (or Tandem) Harrows cut the soil in two different directions.
What are the two types of harrow?
Types of Disc Harrows
- Light disc harrows; with a disc diameter of 20-30 cm.
- Middle disc harrows, with a disc diameter of 30-50 cm.
- Heavy disc harrows, with a disc diameter more than 60cm.
What is an offset disc harrow used for?
Used in open field working for the superficial ploughing, for the shattering of clods, preparation of soil for sowing, burial of organic substances & remains. It can be used in light and medium soil.
What is the difference between a tandem and offset disc?
There is a difference between a tandem and a double offset. On a true tandem the front and rear gangs are directly across from each other. On a double offset, the left side will be slightly staggered from the right side, so that the front gangs overlap slightly, eliminating the middle ridge.
Is harrow used for weeding?
The removal of weeds is called weeding. Weeding is necessary since weeds compete with the crop plants for water, nutrients, space, and light. A harrow is also used to uproot weeds.
How do you use a harrow disc?

- Adjust the cutting depth of the disc harrow.
- Lower the disc harrow into the ground to operate it.
- Cover the entire field with several passes of the disc harrow.
- Lubricate the disc harrow when you finish for the day.
How fast should you run a disc harrow?
Properly pair the tractor and tillage tool. Size does matter, so don’t overpower the tool. A general rule is 8 to 10 HP per foot to pull a tandem disc harrow at 5 to 6 mph. While the design of some tillage tools allows faster ground speeds, going too fast is an easy way to create ridges and furrows.
