Whether you’re a seasoned farmer or just getting started with farming, finding the right harrow tool can make a world of difference in your harvest.

Types of Harrow: Your Handy Guide  

Eager to discover the different types of harrow? Your wait is over; the information you seek is just a scroll away. 

Let’s explore the world of harrows together.

Disc Harrow 

Disc harrow is a farming tool used for soil preparation. It consists of spinning discs mounted on a shared rod or axle.

The purpose of a harrow with a disc is to break up soil clumps, mix in organic matter, and create a smooth seedbed for planting. It is particularly effective for working on tough ground covered with debris or crop residue.

These harrows can have one or more axles, and you can change the angle of the discs to match the direction you’re moving in.

This adjustability allows farmers to control the depth and aggressiveness of the tillage. When it is pulled forward by a tractor or other machinery, the spinning discs come into contact with the soil, breaking it up and improving its texture.

Kelly Disc Harrow 

The Kelly Diamond Harrow serves as an essential tool for farmers, as it effectively handles slightly wet soil without creating clumps or compacting the ground.

Concentrating on the top one or two inches of soil allows for quicker drying, ultimately saving valuable time, a precious commodity in farming. The immediate benefit of using it is a decrease in horsepower and energy usage.

We take great pride in presenting to you our finest selection of harrows. Here is a list of the top ones:

Kelly 12X

Kelly 12X the new and improved way to do shallow tillage. With strong sealed bearings and a sturdy steel frame, it’s great for smoothing soil and taking care of weeds, even with low-power machines.

Model 6218

The powerful Model 6218HDX can handle difficult tasks with ease. Featuring twin drawbar cylinders, load-sharing axles, and the option for outer wing dual wheels, this heavy-duty model has exceptional durability. Additionally, it offers increased module clearance for navigating over soil banks.

Mode 4614

The Model 4614 is an enhanced version of the Model 4012, offering various improvements. These upgrades include increased underframe clearance, a larger jockey wheel, a reinforced high-strength frame, and the option for dual outer wing wheels to enhance flotation.

Additionally, this model is designed to work smoothly with the KELLY Seeder, an integrated air seeder unit specifically built for establishing cover crops.

Disc harrows are categorised into two main types based on how the discs are arranged:

OffSet-Disc Harrow 

The offset disc harrow distinguishes itself from other disc harrow types by having disc gangs that are not aligned with the tractor pulling it. Similar to the double-action disc harrow, it features two rows of disc gangs that break soil in opposite directions.

Typically, offset disc harrows are among the largest in size compared to other variants. They excel when used on expansive fields and are primarily designed for primary tillage, particularly for breaking untouched soil. The action of these harrows results in a significantly smoother and more level ground surface.

Single-Action Disc Harrow

Single-action disc harrows are specialised farm implements designed to till the soil in a single direction.

These are commonly used by farmers with smaller farms, as their cutting width typically ranges from 4 to 20 feet, making them relatively narrow compared to other harrows.

Due to the uniform operation of their disc gangs, they create distinct soil ridges and furrows. These harrows are ideal for more precise and controlled tilling in compact areas, often requiring manual pulling or other hands-on soil management techniques to accompany their use.

Double-Action Disc Harrow

A double-action disc harrow, also known as a tandem disc harrow, features multiple rows of disc gangs. The front gangs work to break the soil in one direction, while the rear gangs break it in the opposite direction. 

This process results in a finer and more uniform soil cut. Unlike a single-action disc harrow, the double-action disc harrow doesn’t create a specific pattern but rather thoroughly mixes and prepares the ground underneath. 

These harrows are excellent for achieving superior levelling of the soil. Due to their larger size, double-action disc harrows are more suitable for larger field areas.

Spike Tooth Harrow

A spike tooth harrow also referred to as a peg tooth harrow, drag harrow, section harrow, or smoothing harrow, is a farm implement with long spike-like teeth. Its primary purpose is to smooth and level the soil right after ploughing.

It is commonly used for early-stage cultivation of crops. You can attach several parts of this farming tool to a hitch bar to cover a wider area when you’re smoothing the soil.

These parts can be either stiff or flexible. Some have rails at the ends, which are called close-end harrows, while others don’t have these rails and are called open-end harrows.

Spring Tooth Harrow 

Spring tooth harrows are produced in sections, similar to spike tooth harrows. These sections come in varying widths. Each section can have between seven to twelve teeth.

You can use a single section on its own, or you can connect multiple sections and use them as a combined unit. The choice of how many sections to use depends on the available power.

The teeth are made from wide, flat, curved bars of spring steel that have been oil-tempered. One end of these bars is securely fastened to a bar, while the other end is pointed to ensure effective soil penetration. 

You can control the depth to which the teeth penetrate the soil by adjusting their angle using levers. Some spring tooth harrows also come equipped with a power-angling hitch for added convenience.

Power Harrow 

A power harrow is a soil cultivation tool that prepares the soil for planting while maintaining the field’s original soil profile.

It accomplishes this by effectively breaking up and mixing both the upper and lower layers of soil without flipping them over.

This process results in an ideal seedbed and soil mulch for planting. The power harrow has two horizontal bars with strong pegs that go back and forth.

These pegs get their power from the tractor. The bars move in different directions to keep everything balanced and working well.


To sum it up, harrows are like the hidden heroes of farming. We’ve taken a look at different types, each with its own special job. The key is to pick the one that fits your needs and the land you’re working on. 

Think about your soil, your area, and what you’re trying to achieve. By making the right choice, you’ll be on your way to better soil and healthier crops, making your farming journey a real success. So, get to know your harrow today, and let them help you grow your best crops!
