Wavy Concave Coulter Blades

Every blade type offers a different set of advantages. When it comes to cutting through crop residue with the greatest efficiency while preparing the soil for seeding, few tools match the unique abilities offered through the use of wavy concave coulter blades.

Wavy Coulter Blades

When it comes to creating the perfect seedbed, choosing the right coulters will help to ensure a good outcome. Plain, notched and ripple coulters all cut aggressively, and bubble coulters can be a good alternative for working sandy soil. However, nothing beats the wavy coulter for cutting through heavy crop residue with the maximum degree of soil disturbance.

Wavy disc coulters come in three basic varieties, and the number of waves on any particular blade will determine the degree to which it will pulverize the soil.

• 8-Wave: A blade consisting of only eight waves is best for working lighter soils where it will accomplish a greater amount of soil fracturing with a lesser degree of soil disturbance.

• 13-Wave Coulter Blade: At a slower rate of travel, the 13-wave coulter will contribute to a more vigorous disruption of the earth and generate a finer tillage. It also throws a smaller amount of soil than the 8-wave does, even when run at higher speeds.

• 25-Wave Coulter Blade: Neither the ripple nor the bubble coulter can work the soil as completely as the 25-wave. Its sharp, narrow edges slice through residue while generating a large quantity of friable soil. While this particular blade will succeed under widely varying conditions, it performs especially well when the earth is wet and yielding.

Wave Count and Harrow Speed
In general, the number of waves on the coulter blade will dictate the speed at which the harrow should run. Wavy coulters do have a tendency to throw the soil, and to prevent this from occurring to an excessive degree, it is best to run higher-wave-count blades at a slower pace.

Width of Wavy Coulter Blades
The width of a wavy blade represents not its thickness, but the distance from the outside of one wave to the outside of another. It is a measurement of wave depth, and the different widths tend to behave as follows:

• Two-inch-wide wavy coulters will generate a broader tilled zone. Although the achievement of soil penetration will require a greater weight, the 2-inch-wide blade will also bury more residue and disturb the soil to a greater degree.

• One-inch-wide wavy coulters will propagate a narrower, finer seedbed. While requiring a lesser amount of weight to pierce the soil, they cut crop residue efficiently and perform better in wet and heavy conditions.

Setting Up Wavy Coulter Blades

In systems that employ two coulters, many agriculturists recommend using a combination of one- and two-inch-wide wavy blades. In a three-coulter setup, on the other hand, it can be best to lead with a two-inch-wide blade in front. This will cut and throw crop residue while creating the least disturbance to the soil. The positioning of two one-inch-wide wavy coulters behind it will accomplish the finer pulverization.

Wavy Concave vs. Conventional Concave

Many people believe that all discs, regardless of appearance, perform in an essentially similar manner. In fact, when it comes to the wavy concave disc, nothing could be further than the truth. While this blade may resemble a coulter on steroids, its differences in curvature and size serve a specific purpose.

The main function of the concave disc is to break up the soil and turn it over while redirecting it toward the concave side. In addition to cutting easily through compacted earth, a disc with the optimal concavity will help to hold the harrow out in loose and loamy soils.

In challenging conditions, a wavy concave disc can outperform the plain concave variety, making short work of cutting into the soil while simultaneously crumbling and incorporating debris. The largest of these will not only cut the deepest, but also bury the greatest amount of crop residue. To add to their abilities, wavy concave discs assist in furrow conservation by provoking less loss of soil. Their use will also impose less stress on the harrow.

There are many options when it comes to purchasing the right disc blades, coulters, and other tillage tools. At Wearparts LLC, we offer the widest selection of coulters, from smooth to wavy concave; and the largest selection of disc blades to provide you with the parts you need for tillage success.

Field Cultivator Parts

As a farmer, you know how important field cultivators are to your business. They’re the machine of choice when it comes to preparing seedbeds before you plant. At Wearparts LLC, we offer a full selection of field cultivator parts and have the knowledge to ensure you get the right parts for your tillage needs.

How Field Cultivators Operate

These devices are designed to eliminate weeds and to properly till the soil before seeds are planted in a field. Cultivators feature sweeps that are positioned 10 to 25 inches apart from one another. Many devices also have large rollers, cultivator shields and cutting discs.

Conventional Sweeps

Wearparts LLC offers three types of cultivator sweeps that can be bolted onto the field cultivator. The smallest component has a width of seven inches, and the largest sweep features a width of ten inches.

The front of each part has a sharp point with a curved design, and as a result, the sweep will naturally dig as deep as possible into the soil to eradicate weeds and to bring fresh, damp soil to the surface of the field.

Our conventional devices also have wings that increase the width of the area that each part is able to cultivate.

Sweeps With Curved Wings

Curved wing sweeps feature widths of six inches to twelve inches, and the angles of the sweeps vary from 47 degrees to 52 degrees. Each of our devices is able to be attached to the cultivator by using two bolts.

The curved sides of each sweep allows the wings to penetrate into particularly thick soil and to till a wider row than the conventional sweeps. Furthermore, numerous studies have shown that a sweep with curved wings and a width of ten inches is able to remove 25 percent more weeds than most conventional devices.

Reversible Double Point

Reversible double points feature holes for the bolts in the middle, and the long, thin design allows them to reach more deeply into the soil than other parts. In spite of this benefit, sweeps that have double points usually won't be able to till an area that is as wide as conventional sweeps.

Sweeps with double points are able to last twice as long as single point sweeps. As soon as one side of the device becomes dull, the user can simply flip the double points and reattach it to the machine.
