Frequently Asked Questions
What is a TMR mixer, and why do I need one?
A TMR (Total Mixed Ration) mixer blends all feed ingredients—such as hay, silage, grain, and supplements—into a consistent ration. This ensures every bite your herd eats is nutritionally balanced, improving milk production, herd health, and feed efficiency.
What makes Penta’s TMR Mixers different from others?
Penta TMR Mixers feature our patented Cyclone Auger, which accelerates material flow and mix consistency while reducing processing time. They’re built with heavy-duty steel construction, planetary gearboxes, and deep-serrated knives to handle even the toughest forages.
How do I choose the right mixer size for my operation?
Your ideal mixer size depends on herd size, feed frequency, and equipment capacity. Our mixers range from 400 to 1,350 cubic feet, with single, twin, and triple auger options. Contact your local dealer or sales rep to find the best fit.
What’s the difference between single, twin, and triple auger mixers?
- Single auger: Compact, efficient, ideal for small to mid-size farms.
- Twin auger: Higher capacity and faster throughput for medium to large farms.
Triple auger: Maximum capacity and mixing speed, perfect for large-scale feeding operations.
Do I need a specific tractor or horsepower to operate a Penta mixer?
Horsepower requirements vary by model. Smaller mixers can be powered by tractors with as little as 75–100 HP, while triple-auger or truck-mounted units require higher capacities. Refer to each model’s specs for PTO and hydraulic needs.
What materials can the mixer process?
Penta mixers are designed to handle a wide range of materials, including:
- Silage (wet or dry)
- Hay and straw
- Corn stalks
- By-products like beet pulp, DDGs, etc.
The serrated knives and auger design ensure thorough cutting and blending of fibrous material.
Are stainless steel liners available?
Yes. Many models offer optional stainless-steel liners on the augers and tub walls to improve clean-out, extend lifespan, and resist corrosion—especially when feeding high-moisture or acidic rations.
How is feed unloaded from the mixer?
Penta mixers feature multiple discharge options, including front, rear, or dual conveyors with flip-up or right/left delivery. Chain and belt styles are available based on your preference and barn layout.
What kind of warranty does Penta offer on its mixers?
Most mixers come with a 3-year or 5-year limited warranty on the gearbox, depending on the auger configuration. Other components are backed by Penta’s strong dealer support and service network.
How do I get service or replacement parts?
