Hillco Technologies

Not Your Grandfather’s Spring Tooth

The short answer is no, read below to find out the differences. 

The Hillco model can be hydraulically spread out and set up without getting out of the cab saving your body and saving you time. The dual wing wheels pivot from transport to field mode as you wing the Springtooth cart out.

The Hillco Spring Tooth comes in 60’ and 72’ widths.

Spring tooth technology has been around for a long time and has remained virtually unchanged. So, you may be asking yourself, “Why would I try a Hillco Spring Tooth? Isn’t it the same as all the others?” The short answer is no, but let’s dig in a little further than that.

Pros & Cons

The older Spring Tooths are great at a few things but also lacking in a few areas. For instance, they are typically wider than a field cultivator and can be pulled faster, meaning more acres per hour. Spring tooths are also great at leveling ground and leaving a nice finish on your field.
But the benefits came at a cost. Right out of the gate, the setup is less than ideal. The grower must get out of the tractor and manually set up the Spring tooth. Your back may be aching just thinking about it.
Then once you’re finally set up and running the amount of residue that would inevitably build up under the Spring tooth would lift your c-tines out of the soil leaving you pulling a big pile of dirt or straw around the field. Cleaning the residue out to get it ready for transport is not the most fun job in the world.
Let’s shift gears. What is it that raises the bar for the Hillco Spring Tooth?

Setup & Transport

If you’re familiar with the way our Hillco Harrow works, then you know how the Spring Tooth will work. Compared to the old ones that you had to wing out manually, the Hillco model can be hydraulically spread out and set up without getting out of the cab saving your body and saving you time. The dual wing wheels pivot from transport to field mode as you wing the Spring Tooth cart out.

Trash Clearance

The Hillco Spring Tooth solves the trash clearance problem by using S-tines instead of C-tines which are a taller style of shank allowing for significantly more residue to flow through. Many of the older C-tine cultivators had 2-3 rows of shanks while the Hillco Spring Tooth has 4 rows of shanks, accommodating more room between S-tines, giving ample room for residue clearance.


The Hillco Spring Tooth comes in 60’ and 72’ widths, a much wider option than was previously available. The 8” tube supporting the frame of the cart is built for longevity and offers a much sturdier option than previous carts.

Seed Bed Preparation

The individual sled design of the Hillco Spring Tooth allows for even contouring of the ground where the rigid structure of older Spring tooths had issues once the ground became uneven.

Each sled of the Hillco Spring Tooth is adjustable, so you can control the depth of the S-tines anywhere from 1 inch to 5 inches. This will allow you to prepare a great seed bed for shallow crops like canola, yet level very uneven ground such as chiseled or plowed ground.
The Spring tooth is followed by 7 sections of flex harrow that leaves an even finish on your field while protecting the moisture deeper in the soil.

Best Conditions for Use

Like any tool, the Spring tooth does best in the conditions it was designed for: Using it in the spring, on chiseled ground, is the sweet spot for the Hillco Spring tooth. As canola becomes more prevalent, a Hillco STH1010 might be just the tool to implement in your operation.

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

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

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.
