Hillco Harrow Cart – Raising the Bar on Spike Wear

Very durable. The Spike design offers heavy duty tooth bars and teeth made from high carbon steel. 

Choosing the right spikes for your harrow will allow you to achieve premium seed bed preparation and deep cultivation. Improper spikes will not allow you to achieve that and lead to having to replace them frequently.

Depends on what spike you choose. Hillco chose Pepin harrow spikes because of the durability and life of the spike.

Continue reading below to see what the spike looked like after putting 30,000+ acres on it. 

The Hillco Harrow Cart has been manufactured with a heavy duty, dependable design that is able to handle the rugged terrain found in the Pacific Northwest. A variety of features showcase the durability of the unit which starts with its 8”x 8” wing tubing. The heavy harrow pulls are built to withstand rocks and it’s robust wing pivot pins feature replaceable bushings for extended wear. These features are just a few things that ensures our Harrow meets the Hillco standard of quality and is the most durable harrow on the market. One of the biggest concerns when it comes to the harrow is the durability of the spikes; Hillco eliminates this concern by choosing the best harrow spike on the market.

Choosing the Best Harrow Spike

To ensure maximum durability, Hillco equips the Harrow Cart with top-of-the-line harrow spikes. With the wrong spikes you won’t be able to achieve premium seed bed preparation and deep cultivation. Improper spikes will also lead to the burden of having to constantly replace the spikes which not only costs you money, but also wastes your time. Opting for maximum durability, Hillco chose Pepin harrow spikes.

Pepin’s Design

Pepin’s spike design offers heavy duty tooth bars and teeth made from high carbon steel, that will reduce bending and breaking as well as ensure “superior penetration, lasting sharpness, double wear and economical single tooth replacement.” They are built perfectly square and smooth to increase durability and reduce clogging since it has no crevices or concave surfaces to fill.

Spike Wear – Putting it to the Test

Hillco has put these harrow spikes to the test and put our stamp of approval on them, after having witnessed the outstanding results of the spikes durability. The picture on the left below demonstrates a brand-new spike measured at 6 1/2 inches. After putting 30,000 plus acres on the Harrow, the spike showed very little wear, measuring at 6 1/8 inches (right picture). The results of the test proved that the Pepin spikes have excellent wear and are a great fit for the Hillco Harrow.

Return on Investment Calculator

This calculator is designed to determine the return on investment for a Hillco leveling system equipped combine versus a non-leveling combine operating in sloping conditions.

Crop Type
Wheat       Corn and Soybean
Acreage Information

Crop Information

Enter your operation's statistics and estimates.

Acreage / Slope Information

Estimate the percentage of total harvested acres that lay within the various slope ranges in your farming operation.
For all Wheat Acreage
See Slope reference chart
Percentage slope values must equal 100%
Your Harvest Speeds and Machine Harvested Yield (MHY)

Non-Leveling Ground Speed in MPH

Enter the average harvesting speed for your non-leveling combine in the various slope ranges at the average yield entered in the Crop Information section above.

Slope Reference Graph

Reduction in Machine Harvested Yield (bu/acre)

Estimate the reduction of Machine Harvested Yield (MHY) for each slope range if you were harvesting at the speed you entered for 0-3% slopes. (The calcultor will then project expected reductions in MHY for each slope range at your previously estimated ground speeds.)

You may opt to enter the test data which was determined by actual field testing by Hillco (based on 5 mph harvesting speed).

Reduction in MHY is used in these calculations rather than field loss. Reduction in MHY is a more accurate guage of combine harvesting efficiency because it can be determined by actually weighing the harvested yield rather than estimating the amount of yield lost to the ground.

Your Combine and Header Information
Enter your expected combine harvesting efficiency. Typically a combine operates at approximately 70% efficiency. If the Total Annual Separator Hours calculated below look too small you may want to decrease the combine efficiency. If the Total Annual Separator Hours calculated below look too large you may want to increase the combine efficiency.

Your Operational Costs
This total should include additional cost of benefits and taxes. If you wish to include the grain cart operator's cost add the hourly wage to the combine operator hourly labor costs.
Combine Operator Labor Cost (per hour, including taxes and benefits)
Combine Fuel Cost

If you wish to include added grain cart fuel add hourly grain cart fuel usage to the combine fuel usage.

Combine Fuel Consumption (Hourly - Typically 11-13 gph)

Cost per added separator hour usually runs approximately $180 per hour for new combines to $30 per hour for older used combines. If you don't want to consider the added benefit of lower separator hours enter $0.

Cost Per Separator Hour
(How much does your combine devalue for each added separator hour of use?)

NPV compares the value of a dollar today to the value of that same dollar in the future, taking inflation and returns into account.
Internal Rate of Return
The internal rate of return (IRR) method allows you to consider the time value of money. It is the interest rate that is equivalent to the dollar returns you expect from your project. Once you know the rate, you can compare it to the rates you could earn by investing your money in other projects or investments. Usually a business owner will insist that in order to be acceptable, a project must be expected to earn an IRR that is at least several percentage points higher than the cost of borrowing, to compensate the company for its risk, time, and trouble associated with the project.
