Silage Spreader for Small vs Large Farms: Which Capacity Matches Your Operation?
The single most common question we get from silage spreader buyers is some version of: “How big should it be?” The wrong answer costs real money. A 5m³ cattle feed spreader on a 30-cow farm is 30% dead weight and an extra USD 1,500 spent on diesel. A 3m³ spreader on a 200-cow farm means 6-7 fill cycles per feeding shift, which is exactly the labor cost the spreader was supposed to eliminate. Here is a clean decision map.
Small Farms: 20-50 Cows
Recommended model: Taizy TZ-3 electric, 3m³ bin, 3600×1500×2000mm. Why this size fits:
- One fill handles 1.5-1.8 tonnes of mixed TMR — enough for 30-40 cows per meal.
- 72V battery with 6 cells runs 2-3 fill cycles on a single charge (4-5 hours of discharge work).
- 1.5/1.5/2.2 kW motors draw less than a household dryer — runs on single-phase 220V with a small inverter or generator.
- Footprint fits through standard 2m barn doors; rear-wheel R3.50-12 + R5.00-12 tires handle packed-earth floors.
Indicative price range: USD 2,500-3,800.
Mid-Size Farms: 50-150 Cows
Recommended model: TZ-5 diesel, 5m³ bin, 4700×1700×2200mm. The jump from electric to diesel here is not about power—it’s about not stopping mid-shift to charge. At this herd size, the spreader runs 3-4 cycles per feeding shift; a 72V battery cannot sustain that on a single charge.
The TZ-5 includes an integrated light-mixing auger, so it can also serve as a basic mixer if you don’t yet have a stationary TMR. This dual role is most valuable in the 50-100 cow segment, where buying both a 5m³ TMR mixer (USD 8,000+) and a separate spreader (USD 5,000+) is hard to justify. Once you cross 100 cows, the dual-function compromise hurts ration consistency and you should separate the two roles.
Indicative price range: USD 4,800-6,500.
Large Farms: 150-500 Cows
At this scale, a single 5m³ spreader becomes the bottleneck. The math: 300 cows × 25 kg TMR = 7.5 tonnes per meal. A 5m³ spreader carries 1.8-2.0 tonnes per cycle, so 4 fill cycles are needed. With 8-10 minutes per cycle (load + travel + discharge + return), one spreader is occupied for 35-40 minutes per meal, leaving zero buffer for breakdowns or uneven feed alley access.
Recommended setup: two TZ-5 diesel units running in parallel, or one TZ-5 paired with a truck-mounted TMR mixer with side discharge. The two-spreader approach has lower capital risk—one unit down for maintenance does not stop the operation. Indicative investment: USD 10,000-14,000 for the pair.
XL Operations: 500+ Cows
Beyond 500 cows, tricycle spreaders reach their limit. The travel distance from the mixing station to the far end of the feed alley exceeds 100m, and the round trip takes 8-10 minutes of empty travel per cycle. At that point the right tool is a truck-mounted TMR mixer with side discharge belt (Taizy 5m³ truck-mounted model with 80cm loading height and 5400×2300×2300mm footprint). This configuration handles 200+ tonnes per day and replaces 2-3 tricycle spreaders while cutting labor to a single operator.
Capacity vs Cost Summary
| Herd Size | Spreader Setup | Capacity per Cycle | Investment (USD) |
|---|---|---|---|
| 20-50 | 1× TZ-3 electric | 1.5-1.8 t | 2,500-3,800 |
| 50-150 | 1× TZ-5 diesel | 1.8-2.0 t | 4,800-6,500 |
| 150-300 | 2× TZ-5 diesel | 3.6-4.0 t | 10,000-14,000 |
| 300-500 | 2× TZ-5 + truck-mounted TMR | 5-6 t | 25,000-35,000 |
| 500+ | Truck-mounted TMR with discharge | 8-10 t | 35,000+ |
FAQ of Silage Spreading Machine
Can I upgrade from 3m³ to 5m³ later by swapping bins?
No. The TZ-3 and TZ-5 use different chassis frames, axle ratings, and conveyor widths. Upgrading means buying a new tricycle, not just a new bin. Plan for the herd size you’ll reach in 3-5 years, not today’s headcount.
Is a 5m³ spreader overkill for a 60-cow farm?
Not necessarily. If you plan to grow to 100+ cows in 2-3 years, the 5m³ diesel TZ-5 is a smarter long-term buy. Just be aware that at 60 cows you’ll run it at 40-50% capacity, which means slightly more feed residue in the bin and a less stable load. Operationally it works; economically it’s a 1-2 year decision to size up early.
Does the tricycle need a special license to operate on public roads?
Regulations vary by country. In most African and Southeast Asian markets, the tricycle spreader is classified as farm machinery and does not require a road license if used on private farm roads. For transport between farms, it can usually be hauled on a flatbed truck. Check local regulations before purchase.
