What Should You Look For In A Disc Harrow?
Cutting option
A tractor disc harrow comes in 3 cutting options: single, double, or offset.
- Single Action Disc Harrows: these harrows can cut the soil in a single direction.
- Double Action Disc Harrows/Tandem Harrows: These harrows can cut the soil in two opposite directions, thanks to the front and rear blades.
- Offset Disc Harrows: This is the most common cutting option because it provides a smooth cut in the soil. You can adjust the hitch to the right or left, so the harrow is placed in an offset position behind the tractor.
Attachment Options
There are two attachment options – 3-point hitch mounted and pulled behind. You can pick up an option that is best suitable for your farm work.
Harrows with a 3-pointed hitch allow you to hang the attachment on your tractor’s hitch for easy transportation and storage. Since you can adjust harrow and disc gangs up and down with the hitch, you will save a lot of time for assembling and ground variations. This harrow type is flexible and can be used in small spaces.
On the other hand, the discs of pull-behind harrows are mounted on disc gangs (or frames) connected with a draw-bar and pulled behind your tractors with wheels. Some latest pull-behind harrows come with hydraulic controls.
Blade type
There are two disc harrow blade types – the notched blades and smooth blades.
Notched blades are powerful and can penetrate the soil easily. Thus, this blade type is often used to cut high vegetation soil like hayfields, cornfields, pasture, cover crops, or hard, clay ground conditions. However, notched blades are expensive and quickly get damaged when cutting through rocky soil.
Smooth blades can cut through rocky soil or sand with no damages. However, you should attach a weight box to the disc gang when cutting through the hard ground to give more penetration power to these blades. Otherwise, they will ride over instead of cutting through the soil.
You should use both these blade types – the notched ones on the front gangs for powerful cuts and the smooth ones on the rear gangs for a smooth finish.
Blade design
Besides blade type, you should also consider the blade design when purchasing a tractor disc harrow. There are two blade designs – flat blades and concave blades. You can pick up a design or utilize these two designs to get the most of your farm work.
- Flat blades: can only penetrate the soil.
- Concave blades: can penetrate the soil and lift and separate the soil to one side.
Diameter
The disc’s diameter plays a vital part in the performance of a disc harrow. The larger the diameter, the faster your job can get done and the lower your turnaround time. Disc harrows with a diameter of 350mm or higher are a perfect combination of pricing and efficiency.
Cutting width
Similar to the diameter, the disc’s cutting width also determines the efficiency and the speed when cutting through the soil.
A cutting width of 50 inches or higher is standard for many gardeners. If you want to shorten your time, you can choose a tractor disc harrow with a higher cutting width with a higher price tag.
Corrosion & Rust protection
Since your tractor disc harrow often works under harsh conditions, you should also prioritize the corrosion and rust protection treatment.
Make sure the harrow is made of galvanized metal and has powder-coating to prevent damage of corrosion and rust. And even if your harrow features this treatment, don’t use it right after rain.
Tow bar
Make sure you choose a disc harrow with an adjustable tow bar because of the following reasons.
An adjustable tow bar ensures that your disc harrow is compatible with your ATV and affects the linkage between the harrow and the ATV. It also helps prevent possible breakages while boosting the versatility of the disc harrow.
Besides the tow bar, you should also check its one-pin mounting. This mounting makes it easy to assemble or disassemble the harrow from your ATV.
How To Use A Tractor Disc Harrow?
Step 1. Prepare the tractor
Choose a tractor that has had sufficient horsepower to pull the disc harrow. The X-shaped harrow can quickly remove all clods or cut vegetation fields that haven’t been cultivated for a long time. However, this harrow type requires tractors with higher horsepower to pull.
Step 2. Set the cutting depth
Make some adjustments to get the appropriate cutting depth of your harrow as follows:
- First, raise or lower the disc harrow from front to back by adjusting the center link attachment between the tractor and the harrow.
- Second, adjust the lift pins from side to side until the harrow is well-balanced.
Step 3. Start driving the tractor
Start operating the disc harrow by lowering it into the ground with the tractor’s speed as the recommendation by the manufacturer.
If you drive too fast, the harrow will leave a groove at the center of the cutting path. If you move too slowly, there will be a valley.
Raise the harrow at the end of the cutting path to make it easier to turn.

Step 4. Cutting again for remaining clods
Continue the remaining cutting paths until you have finished cutting the entire field. If there are still clods on the field, do the cutting job again in another direction.
Step 5. Finish & clean the disc harrow
When you have finished your work, don’t forget to lubricate your disc harrow to prevent it from rust and corrosion. Clean all debris on the harrow first, then use a grease gun to insert grease into the grease zerks.
Frequently Asked Questions
1. Is a disc harrow better than a tiller?
The choice between a disc harrow and a tiller depends on your garden size and soil condition.
A disc harrow can perform better through hard soil. It can dig several feet into the ground. On the other hand, a tiller is more suitable for small gardens, and it can only turn from 6 to 10 inches of the topsoil layer.
2. What is the difference between a disc harrow and a cultivator?
There are some differences between a disc harrow and a cultivator.
First, a disc harrow uses discs for soil penetration and is often used for large-sized farming or large acreages of cultivation crops, while a cultivator is a better fit for small gardens or lawns and uses sharp tines for tilling the soil.
Second, a disc harrow is more powerful and can dig deeply several feet into hard soil, while a cultivator can go down from 6 to 10 inches off the ground.
Third, you must have a tractor and have an attachment (or a connector) to pull a disc harrow. On the other hand, a cultivator can work independently by using a rechargeable battery or gasoline.
3, What is the difference between a disc harrow and a chain harrow?
A disc harrow differs from a chain harrow in its appearance, function, and ways of use:
- Appearance
A chain harrow looks like a fishing net with extensive holes, while a disc harrow looks like a long stick with many round blades.
- Function & ways of use
A chain harrow can only dig 3-4 inches off the ground. Thus, it is often used to aerate the soil, lift unwanted materials and weeds off the ground, or break large pieces of soil on landscaping projects. Sometimes farmers also use this harrow to spread fertilizer evenly in the cultivation fields.
Conversely, a disc harrow is more powerful and can dig several feet off the ground to remove crop residue or weed roots. Thus, it is often used for soil preparation and cultivation purposes.
