Silage Spreader vs TMR Mixer: Which Machine Does Your Farm Actually Need?
One question lands in our inbox every week: silage spreader or TMR mixer—which one? The honest answer is “it depends,” but that is not where the decision starts.
It starts with a sharper question: where is your feeding process breaking down?
If feed piles up unevenly along the bunk and the last cows in the line get shorted, the bottleneck is distribution—you need a cattle feed spreader.
If milk yield swings batch to batch because the ration is not consistent, the bottleneck is mixing—you need a TMR mixer. They fix different problems, at different points in the workflow.
What Each Machine Does
The silage spreader is the last mile of feeding. It is a tricycle-mounted bin with a scraper conveyor and a side discharge door. Its job is simple: take finished feed and lay it down evenly along the alley. Some diesel models (the Taizy TZ-5, for example) add a light mixing auger, but distribution is still the primary function.
The TMR feed mixer is the heart of ration accuracy. It is a stationary or truck-mounted tub with one or two heavy augers, on-board load cells, and a digital scale. It chops long fiber, weighs each ingredient, and blends them into a uniform Total Mixed Ration that cows cannot sort through.
Side-by-Side Comparison: Silage Spreader vs TMR Mixer
| Dimension | Silage Spreader | TMR Mixer |
| Primary function | Distribute mixed feed to bunk | Chop, weigh, and blend ingredients |
| Capacity range | 3-5 m³ | 5-20 m³ |
| Throughput | 1.5-2.5 t per fill cycle | 3-12 t per batch (15-25 min each) |
| Source d'alimentation | Electric 1.5-2.2 kW or diesel | 11-75 kW electric or 35-150 HP diesel |
| Operator skill | Low (drive and discharge) | Medium (recipe loading, scale calibration) |
| Empreinte | Mobile, 3.6-4.7 m long | Stationary or truck, 3.9-5.6 m long |
| Investment | USD 2,500-6,500 | USD 5,000-20,000 |
| Labor saved | 1-2 workers per feeding shift | 3-5 workers per mixing shift |
| Feed waste cut | 5-8% (less spillage) | 8-15% (less sorting, steadier intake) |
| Service interval | Every 200 h (chain, bearings, brake) | Every 100 h (auger blades, gearbox oil) |
When a Silage Spreader Is the Right Answer
You already own or share a stationary mixer, and your only problem is uneven bunk distribution. A spreader closes that gap in a matter of days. The farm profile that fits:
- 20-80 cow dairy or beef operation
- Stationary TMR mixer on site, 5 m³ or larger
- Single feed alley under 80m long
- One operator handling both mixing and feeding
When a TMR Mixer Is the Right Answer
You are over 80 cows and still hand-blending silage, hay, concentrate, and minerals in a wheelbarrow. The signs are familiar: milk yield swings from one batch to the next, body condition drifts across the herd, and cows nose through the ration for the grain. A TMR mixer pays back in 12-18 months on labor alone, before any production gains. The profile that fits:
- 80-500 cow dairy or beef feedlot
- Multi-ingredient ration with 4+ components
- Nutritionist-formulated recipes that need on-board weighing
- Feed cost above USD 200 per cow per year, where 5% waste is real money
When You Need Both
Above 100 cows, mixing and feeding run in parallel. The TMR mixer prepares the next batch while the spreader distributes the previous one.
Folding both jobs into a single machine on a 200+ cow farm almost always ends one of two ways: the herd runs out of feed mid-shift, or the operator skips a ration step to catch up.
The most common pairing in this segment: a 9-12 m³ TMR mixer working with a TZ-5 diesel feed spreader.
Cost vs Payback by Herd Size
| Herd Size | Recommended Setup | Indicative Cost | Payback |
| 20-50 cows | Spreader only (TZ-3 electric) | USD 2,500-3,500 | 8-12 months |
| 50-100 cows | Spreader (TZ-5 diesel) + 5 m³ TMR | USD 5,000-10,000 | 14-20 months |
| 100-300 cows | Spreader (TZ-5 × 2) + 9-12 m³ TMR | USD 8,000-20,000 | 18-26 months |
| 300+ cows | Spreader fleet + 15-20 m³ TMR | USD 10,000+ | 22-30 months |
FAQ of Silage Spreader vs TMR Mixer
Can a TMR mixer handle bunk spreading on its own?
Some truck-mounted TMR mixers have a side discharge conveyor, but the spread pattern tends to be coarse and uneven compared with a dedicated silage spreader. The TMR mixer is built for blending, not distribution. For steady bunk feeding, run a spreader downstream.
I run 60 cows. Which one do I buy first?
Start with the TMR mixer. At 60 cows, ration consistency has more impact on production than distribution uniformity. Once the TMR is in place, the spreader is a fast upgrade you can add 6-12 months later.
Will a Taizy spreader work with other TMR mixer brands?
Yes. The spreader sits downstream of the mixer and takes finished feed by direct load—either a front loader or a gravity chute. There is no electronic handshake between the two machines, so brand does not matter.
