Simple Ground-Drive Rate Control for Fertilizer, Lime, and Farm Materials
For a small to mid-size corn-and-hay operation that spreads fertilizer every season and lime every few years, owning one dependable spreader can make a lot of sense.
The Stoltzfus Redhawk is a ground driven fertilizer and lime spreader built for farmers who want simple, reliable rate control without relying on complex electronics. The ground-driven body chain keeps material flow tied to travel speed. As the spreader moves faster, the conveyor moves faster. As the spreader slows down, the conveyor slows down.
That simple mechanical relationship helps maintain a consistent application rate in normal field conditions.
The Redhawk is rugged enough for lime, precise enough for fertilizer, and versatile enough for gypsum, poultry litter, compost, wood ash, and other compatible farm materials.
If you want a pull-type spreader that is simple to operate, durable in the field, and capable of handling more than one material, the Redhawk Ground Drive Spreader is built for that job.

The Redhawk — A Ground Driven Fertilizer and Lime Spreader You Can Count On
The Redhawk ground drive fertilizer and lime spreader features a double-contact press wheel that provides enough power to break free a packed load of lime, while still providing the ground drive precision you expect in a ground driven fertilizer spreader.
The body chain (conveyor) is driven by a press wheel that contacts both ground wheels on the walking beam suspension, providing extra traction. The press wheel is operated hydraulically from the tractor to start and stop the spreader — no ropes to pull! The spinners are powered by tractor hydraulics or PTO mechanically driven.
The gate height determines spread rates, and the ground drive mechanism ensures a constant spread rate regardless of travel speed.

One Ground Drive Spreader for Fertilizer, Lime, and More
The Redhawk is designed for farms that do not want to own one spreader for fertilizer and another spreader for lime. It combines ground-speed-based conveyor control with heavy-duty construction, giving farmers a practical spreader for a wide range of farm applications.
Use the Redhawk for common materials such as:
- Fertilizer, including rates down to 125 lbs./acre
- Stockpiled ag lime, wet lime, and damp lime
- Gypsum
- Poultry litter
- Compost
- Wood ash
- Pelletized lime
- Pelletized fertilizer
- Similar dry or semi-dry bulk materials
For high-volume poultry litter or compost applications, see our Bulk Material Spreaders to compare which Stoltzfus model is the better fit.
What Benefits Will You Experience?
Owning your own ground driven fertilizer and lime spreader gives you more control over timing, field conditions, and application cost.

The Stoltzfus Ground Drive Spreader Difference
When shopping for a new ground drive spreader, what criteria will you use to make your purchase decision?
Is it Tough?
Yes. The Redhawk is built as a heavy-duty farm spreader, not a light fertilizer cart. It uses a strong frame, heavy conveyor components, steep hopper sides, and a design meant to handle fertilizer, lime, gypsum, poultry litter, compost, and similar materials.
The spreader is built for real farm use, including heavier materials that lighter spreaders may not handle well.
Toughness is standard on every Stoltzfus ground drive spreader.
Is it Versatile?
Yes. Many farms need to spread more than one material. The Redhawk is designed for fertilizer and lime, but it can also handle gypsum, poultry litter, compost, wood ash, pelletized materials, and other compatible farm products.
For high-volume litter and compost work, our Bulk Material Spreaders may be a better fit. For primarily lime applications, compare the Redhawk with the Stoltzfus Wet Lime Spreader.
Versatility is built into every Stoltzfus ground drive spreader.
Can it Perform?
Yes. The ground drive system keeps the body chain tied to ground speed, helping maintain consistent material flow during normal field operation.
With the standard fertilizer kit, the Redhawk can apply fertilizer at lower rates. With its heavier construction, it can also handle lime and gypsum applications that require more strength than a basic fertilizer spreader.
Performance is engineered into every Stoltzfus ground drive spreader.
Will it Last?
The Redhawk is built for long-term farm use, not just light seasonal fertilizer work.
The spreader uses heavy conveyor components, steep hopper sides, and a rugged frame designed to handle fertilizer, lime, gypsum, poultry litter, compost, and similar materials. The top-driven spinner design helps keep critical drive components away from the direct impact of material coming off the conveyor, which helps reduce wear in one of the hardest-working areas of the machine.
Longevity is a hallmark of every Stoltzfus ground drive spreader.
The Stoltzfus Difference will change how you spread lime, fertilizer, and other materials.
The right spreader does more than move material. It gives you control over when you spread, how accurately you apply, and how well the machine holds up over time.
The Redhawk Ground Drive Spreader is built for farmers who want a simple, dependable way to spread fertilizer, lime, gypsum, poultry litter, compost, and similar farm materials with one machine. The ground drive system keeps the body chain tied to ground speed, while the heavy-duty construction gives the machine the strength needed for heavier materials like lime and gypsum.
If you are comparing a ground driven fertilizer spreader, ground drive lime spreader, PTO-driven spreader, or another pull-type spreader, Stoltzfus can help you sort through the options. We will look at your tractor, material, acreage, field conditions, and application rates so you can choose the spreader that fits your operation.

Frequently Asked Questions About Ground Drive Spreaders
Buying a ground drive spreader is a significant equipment decision. These are the questions we hear most from commercial farmers and operations managers before they purchase. If you don't see your question answered here, call us directly, and we'll give you a straight answer.
What Is a Ground Drive Spreader?
A ground drive spreader uses wheel movement to drive the body chain or conveyor. As the spreader moves across the field, the conveyor moves in proportion to travel speed. This helps keep material flow tied to ground speed.
Is the Redhawk a good fertilizer spreader?
Yes. The Redhawk is a good option for farms that want a ground driven fertilizer spreader with simple mechanical rate control. With the standard fertilizer kit, it can apply fertilizer at rates as low as approximately 125 pounds per acre, depending on material, conditions, and machine setup.
Can the Redhawk spread lime?
Yes. The Redhawk is built to handle ag lime, including damp or stockpiled lime in many conditions. It can apply ag lime at rates up to approximately 7,000 pounds per acre, depending on material, speed, gate setting, and spreader configuration.
If wet lime is your primary spreading challenge, Stoltzfus can help you compare the Redhawk Ground Drive Spreader with the Stoltzfus Wet Lime Spreader.
What’s the difference between the Redhawk and the Stoltzfus Wet Lime Spreader?
The Redhawk is a ground driven combination fertilizer and lime spreader for farms that want simple ground-speed-based rate control. The Wet Lime Spreader is PTO or hydraulically powered and more specifically focused on spreading difficult wet, damp, or stockpiled ag lime.
Can I Pull a Ground Drive Spreader With an ATV or UTV?
No. Redhawk spreaders are large farm implements designed to be pulled by an appropriately sized tractor. ATVs and UTVs are far too light for this type of spreader, especially when the machine is loaded.
Does a ground drive spreader need tractor hydraulics?
Yes. The Redhawk uses a hydraulic cylinder to activate the ground drive for the body chain. The spinners can be set up for hydraulic (standard) or PTO power.
What sizes are available?
Redhawk Ground Drive Spreaders are available in 4, 5, 8, and 10 ton models. The right size depends on your tractor, acreage, material density, and application rates.
Can one spreader handle both fertilizer and lime?
Yes. That is one of the main reasons farmers choose the Redhawk. It is built to handle both fertilizer and lime, giving farms one versatile machine for multiple spreading jobs.
Is the Redhawk a manure spreader?
The Redhawk is not a traditional beater-style manure spreader. It is a spinner spreader designed for fertilizer, lime, gypsum, poultry litter, compost, and similar materials. If you are spreading manure or another high-moisture organic material, contact Stoltzfus to confirm the right equipment for your application.
