LEO Agriculture is a vertical TMR feed mixer manufacturer. We build twin auger vertical mixers for dairy, beef and feedlot operations, plus mini mixers for small herds. Our North America factory and HQ is in Monroe, Wisconsin, and our mixers go to farms in the USA, South Africa and beyond.
When you’re comparing manufacturers, the brochure words all start to sound the same. What matters is the steel, the augers, the knives, the scale, the power you need and who supports you after the sale. This post lays out exactly how we build our mixers, with the real numbers from our product pages, so you can compare apples with apples.
The LEO vertical TMR mixer lineup
We build three families of vertical mixer.
- Mini mixers: the single auger 7003 (3 m³) and 7004 (4 m³) for small herds. See mini mixers.
- VT Series: seven twin auger models from 6 m³ (7006VT) to 21 m³ (7021VT). See the VT twin auger feed mixers.
- HD Series: eight heavy duty twin auger models from 14 m³ (7014HD) to 45 m³ (7045HD), with custom commercial builds on order. See the HD heavy duty feed mixers.

Why we build twin augers
A single auger does fine in a small round tub. Stretch the tub out for more capacity and one auger can leave feed sitting at the ends. Two counter-rotating augers keep the whole load turning, so the ration comes out the same from front to back. That’s why every VT and HD model runs two vertical augers, and only our smallest minis run one.
More on the difference in single auger vs twin auger vertical mixers.
The tub and the steel
A vertical mixer wears from the bottom up. Sand, acid and hay grind on the floor and the lower auger every load, so that’s where we put the steel.
| Range | Floor | Walls | Lower auger | Upper auger | Stainless liners |
|---|---|---|---|---|---|
| 7006VT | 12 mm | 4 mm | 12 mm | 12 mm | Optional |
| 7010VT | 12 mm | 6 mm | 12 mm | 12 mm | Optional |
| 7013VT to 7021VT | 12 mm | 6 mm | 16 mm | 12 mm | Optional |
| HD, all models | 20 mm | 9 mm total (6 mm + 3 mm stainless) | 20 mm | 20 mm | Standard |
The VT range is built for family dairies and beef operations mixing a few loads a day. The HD range is built for feedlots and commercial operations where the mixer runs most of the day. Read vertical TMR mixer build quality for what each number means in practice.
Augers and knives
Knives decide how fast a bale breaks down and how much diesel you burn doing it.
| Model | Auger knives | Side wall knives |
|---|---|---|
| 7006VT | 18 (8 small, 10 large) | 2 |
| 7010VT | 22 (12 small, 10 large) | 2 |
| 7013VT | 22 (12 small, 10 large) | 3 |
| 7021VT | 12 | 3 |
On the HD range we use a modular blade system. Each cutting blade is individually replaceable, so you swap one worn blade in minutes instead of replacing a whole set. See vertical TMR mixer augers and knives.
Scales on every mixer
A mixer only pays when you feed what you planned. Every VT model has load cells: 3 on most models, sized up from 2.125 inch on the 7006VT to 3.125 inch on the 7013VT, and 4 load cells on the 7021VT. Every HD model has a 4-point scale system as standard.
Driveline and power
Smaller VT mixers run on a 540 RPM PTO so they pair with mid-size tractors. From the 7013VT up, and on every HD model, we go to 1,000 RPM for more auger torque. HD models also carry a hay retention chain as standard. Match the listed HP to the tractor you’ll really use. See feed mixer power requirements.
Discharge options
- VT: side door on every model, 610 mm on the 7006VT and 760 mm from the 7010VT up.
- HD: side discharge on the 7014HD to 7018HD, front discharge on the 7025HD to 7034HD, two side discharges on the 7040HD and 7045HD.
Custom commercial builds
For commercial feed centres we build to order on the HD platform:
- Capacities beyond 45 m³.
- Truck mounted configurations.
- Stationary installations.
- Custom discharge, auger and blade setups.
- Scale and feed management integration.
Built to ship worldwide
All seven VT models fit a standard 40 ft container, which keeps freight simpler for farms outside North America. Read buying from a vertical TMR mixer manufacturer.
Which LEO mixer fits which farm
Here’s how the lineup usually matches up with the farms we talk to. These are starting points from the Best For ranges on our product pages. Your ration and how many loads you mix will change the answer.
- Hobby farms, sheep and goats, and herds under 50 head: the 7003 or 7004 mini mixer.
- Small to mid dairies of 50 to 150 cows, backgrounding lots, or a first full size mixer: the 7006VT.
- Growing dairies of 100 to 200 cows or mixed beef and dairy: the 7008VT.
- Mid size dairies of 150 to 300 cows, commercial beef feedlots, several groups a day: the 7010VT, with heavier 6 mm walls and a 760 mm door.
- Large dairies of 300 to 600 cows and custom feeding: the 7013VT, with a 16 mm auger bottom and 1,000 RPM driveline.
- Large dairies of 400 to 900 cows: the 7015VT or 7018VT.
- 700+ cows and custom feeding contractors: the 7021VT, with 4 load cells.
- Feedlots and commercial feed centres feeding most of the day: the HD range, from the 7014HD up to the 7045HD or a custom build.
What happens when you contact us
When you call or send a quote request, we’ll ask about:
- Your largest feeding group and how many groups you feed.
- Your ration, especially how much hay or whole bales go in.
- Your tractor and its PTO speed.
- Your loader and the loading height it can clear.
- Your feed alley, bunk side and any tight turns.
- Where you’re located, so we can connect you with a dealer, distributor or wholesaler near you, or handle it from our North America team.
From there we’ll recommend a model and options such as stainless liners on the VT range, discharge setup on the HD range, or road lights. If you’re overseas, we’ll talk through container shipping.
Why the numbers matter more than the paint
Every mixer looks good new. Five years in, what’s left is the steel, the gearbox and how easily you can get parts. That’s why we publish floor, wall and auger thickness, knife counts, load cell sizes and power for every model on our product pages. Hold any manufacturer to the same standard.
How to choose a vertical TMR feed mixer manufacturer
Ask every manufacturer the same questions and make them answer in numbers:
- Floor, wall and auger thickness in mm or inches.
- Single or twin auger, by model.
- Knife count and whether you can replace one at a time.
- Stainless liners, standard or optional.
- Load cell count and size.
- HP and PTO speed per model.
- Loading height.
- Discharge options.
- Parts supply near you.
- Dealer and factory support.
We put the full checklist in choosing a vertical TMR feed mixer manufacturer.
Common mistakes when buying from a manufacturer
- Comparing on capacity only, without checking steel and knives.
- Ignoring tractor fit until the mixer arrives.
- Skipping the scale to save money, then losing it in feed waste.
- Not asking about parts before you sign.
- Buying too big and running it half full, or too small and running it packed.
Looking after a LEO mixer
Grease to schedule, change gearbox oil on time, keep knives sharp, check shear bolts and calibrate the scale. See feed mixer maintenance schedule and vertical mixer gearbox myths.
