Disc harrows are essential agricultural implements used for soil cultivation, primarily in tillage operations. They consist of a series of concave steel discs mounted on a frame, which cut through and turn the soil, preparing it for planting. These tools are vital for breaking up clods, incorporating crop residues, and leveling the ground, making them a cornerstone of modern farming practices.
Our disc harrows are engineered for durability, efficiency, and performance. Below are the detailed specifications presented in lists and tables for clarity.
| Model | Working Width (ft) | Disc Diameter (in) | Number of Discs | Weight (lbs) | Hitch Category | Max HP Requirement |
|---|---|---|---|---|---|---|
| DH-400 | 4 | 16 | 8 | 500 | 1 | 30 HP |
| DH-800 | 8 | 18 | 16 | 1000 | 2 | 60 HP |
| DH-1200 | 12 | 20 | 24 | 1500 | 2 | 90 HP |
| DH-1600 | 16 | 22 | 32 | 2000 | 3 | 120 HP |
| DH-2000 | 20 | 22 | 40 | 2500 | 3 | 150 HP |
Disc harrows are versatile tools used in various farming operations. They excel in primary and secondary tillage, helping to create a fine seedbed. Benefits include improved soil aeration, weed control, and moisture retention. These implements are ideal for preparing land for crops like corn, wheat, and soybeans, and can be used in both dry and wet conditions with proper adjustment.
What is the ideal disc harrow for small farms?
For small farms with limited tractor power, models like the DH-400 with a 4-foot width and Category 1 hitch are perfect. They require as little as 30 HP and are easy to maneuver in tight spaces.
How often should I maintain the bearings on a disc harrow?
Bearings should be inspected before each use and lubricated every 50 hours of operation. Sealed bearings reduce maintenance frequency, but regular checks prevent premature wear.
Can disc harrows be used on rocky soil?
Yes, but it's recommended to use models with heavier frames and larger discs (e.g., 22 inches) to handle obstacles. Adjust the gang angle to a shallower depth to avoid damage.
What is the difference between a disc harrow and a plow?
A plow is primarily for turning over the soil at greater depths, while a disc harrow is for cutting, mixing, and leveling the topsoil. Disc harrows are better for incorporating residues and preparing seedbeds.
How do I choose the correct disc spacing?
Narrower spacing (6-7 inches) is better for fine tilth and weed control in prepared fields, while wider spacing (8-9 inches) suits heavier soils and residue management. Adjust based on your soil type and crop needs.
Are disc harrows suitable for organic farming?
Absolutely. They help manage weeds and incorporate organic matter without chemicals. Ensure models have adjustable settings to minimize soil disturbance and preserve soil health.
What tractor horsepower is needed for a 12-foot disc harrow?
A 12-foot model, such as the DH-1200, typically requires a tractor with at least 90 HP to operate efficiently in most soil conditions. Always check the manufacturer's recommendations for your specific soil type.
Can I use a disc harrow for pasture renovation?
Yes, disc harrows are excellent for pasture renovation. They can break up compacted soil, incorporate seeds, and improve forage growth. Use a model with sharper discs and adjust the depth for best results.
How do I store a disc harrow to prevent rust?
Clean thoroughly after use to remove soil and debris. Store in a dry, covered area, and apply a light coat of oil on discs to prevent corrosion. Regular maintenance extends the implement's lifespan.
What safety precautions should I take when operating a disc harrow?
Always wear protective gear, ensure the implement is properly hitched, and keep bystanders clear. Engage safety locks when transporting, and never make adjustments while the equipment is in motion.
