Towed-Type Haylage Baler
The 9YDB-100 haylage baler is a drawbar-type, all-in-one baling and wrapping machine with a built-in 2.7 m³ bunker. It uses imported Japanese high-density baling technology to produce round bales (Φ100*85cm) of 400-500 kg at densities up to 750 kg/m³.
With an intelligent control panel enabling fully automatic operation and a 40-60 bales/hour throughput, the 9YDB-100 is the ideal choice for medium-scale livestock farms that want to produce commercial-grade haylage bales for storage and long-distance transport.
What Is a Haylage Baler?
A haylage baler is a machine that compresses freshly cut forage—grass, alfalfa, whole-plant corn, or sorghum—into dense, airtight round bales wrapped in specialized silage film. Unlike dry hay, haylage is preserved at moisture levels of 40-60% through natural lactic acid fermentation inside the sealed bale. This produces a higher-energy, more palatable feed that retains more nutrients than sun-dried hay.
The 9YDB-100 haylage wrapper combines three functions in one machine: feeding, baling, and wrapping. The built-in bunker receives material from a chaff cutter or pickup, the baling chamber forms the round bale, and the wrapping arm seals it automatically. One operator, one tractor, one machine—complete haylage production.
Key Features and Advantages of the 9YDB-100 Haylage Baler
- Imported Japanese High-Density Baling Technology — Proven 750 kg/m³ density for compact, transport-ready bales that hold shape during long-distance shipping
- Power-Efficient Drive — Runs on just a 37 kW electric motor or 70 HP tractor, far less fuel and energy than comparable self-propelled harvesters
- Intelligent Control Panel — Fully automatic operation from feeding through wrapping, single-operator workflow that cuts labor costs
- High Bale Density (750 kg/m³) — 500 kg per round bale at standard silage moisture, reducing transport and storage cost per ton of forage
- Built-in 2.7 m³ Bunker — Continuous feeding buffer between the chaff cutter and the baling chamber, no manual loading or auxiliary conveyor needed
- Tow-Behind Tractor Design — Standard 10.0/75-15.3 tires and drawbar coupling, compatible with any 70+ HP tractor for field-to-field mobility
- Long Storage Life — Sealed film prevents oxygen and moisture entry; haylage keeps 12-24 months with no nutrient loss
- Versatile Crop Handling — Works for whole-plant silage, yellow stover, alfalfa, sorghum, and mixed grass-legume stands
- Built for Medium Farms — Capacity matches the 100-500 head dairy or beef operation, the right size for commercial-grade production

Silage Round Bale Quality and Specifications
| パラメータ | Value |
|---|---|
| Bale Diameter | 100 cm |
| Bale Width | 85 cm |
| Bale Weight (Standard Silage) | 400-500 kg |
| Density at Standard Moisture | 750 kg/m³ |
| Net Layers | 0–5 Layers (adjustable) |
| Film Layers | Layer by Layer (adjustable) |
| Storage Life (Sealed) | 12-24 months |
At 750 kg/m³ density, each bale weighs close to 500 kg. This means fewer bales to move, lower transport cost per ton of forage, and better fermentation quality because oxygen is excluded more effectively from a tightly packed bale.
Two Power Options for Every Farm
The 9YDB-100 haylage baler wrapper accepts two power sources, giving farms flexibility based on their existing equipment:
- 37 kW Electric Motor — For fixed-location operations with stable three-phase power. Lower running cost, quieter operation, no fuel storage needed.
- 70 HP Tractor (PTO) — For mobile field operations. Hook up any 70+ HP tractor, drive to the field, and start baling. No dependence on grid power.
Most medium-scale farms choose the tractor PTO configuration because it allows the baler to follow the chaff cutter across multiple fields. The 400 min⁻¹ PTO speed matches standard European, American, and Asian tractor specifications.
Why the Built-in 2.7 m³ Bunker Matters
Most baler-wrappers on the market require manual or separate-conveyor feeding into the baling chamber. The 9YDB-100 haylage baler machine integrates a 2.7 m³ bunker directly into the machine frame. Here’s what this changes:
- Continuous feeding — Material flows from the bunker to the baling chamber without stopping
- No manual loading — The chaff cutter or pickup discharges directly into the bunker
- Buffer for uneven feed rate — If the upstream cutter pauses, the bunker keeps the baling chamber running for several minutes
- Single-operator workflow — One person runs both the cutter and the baler
In practical terms, the bunker turns the 9YDB-100 haylage round baler from a baler into a complete haylage production station—a meaningful upgrade over baler-wrappers that need auxiliary equipment to keep them fed.
Baling and Wrapping Workflow
- Feed — Chaff cutter or pickup discharges cut forage into the 2.7 m³ bunker
- Compact — The baling chamber forms a 100 × 85 cm round bale under high pressure (750 kg/m³)
- Tie — Net wrap (1050 mm width) automatically ties the bale
- Wrap — The wrapping arm applies 4-6 layers of 500 mm silage film
- 放電 — Sealed bale ejected onto the ground, ready for storage or transport
Total cycle time per bale: 60-90 seconds. With intelligent control, the operator only monitors the panel and handles occasional net/film roll changes.
Applications of Haylage Baler Machine
| Crop Type | Best Use Case |
|---|---|
| Whole-plant corn | High-moisture corn silage for dairy cattle |
| Yellow corn stover | Dry stover silage for beef cattle and sheep |
| Alfalfa | High-protein legume haylage for dairy |
| Sorghum and millet | Drought-resistant forage for semi-arid regions |
| Grass-legume mix | Standard haylage for mixed livestock |
Haylage vs Traditional Hay: Why It Matters
| Factor | Sun-Dried Hay | 9YDB-100 Haylage Bales |
|---|---|---|
| Moisture at Baling | <20% | 40-60% |
| Nutrient Retention | 60-70% | 85-90% |
| Weather Risk | High (rain damage) | None (sealed immediately) |
| Storage Life | 6-12 months | 12-24 months |
| Feed Value per Ton | Baseline | 20-30% higher energy |
The biggest difference: haylage is preserved the same day it’s cut. Sun-dried hay needs 3-5 dry days and loses nutrients to leaf shatter, weather damage, and over-drying. With the 9YDB-100 haylage baler machine, you cut in the morning and have sealed bales by afternoon.
How to Choose the Right Silage and Hay Baler?
- Under 50 head of cattle — A smaller walk-behind or compact baler may be enough
- 50-300 head of cattle — The 9YDB-100 haylage baler is the right size, matching the 40-60 bales/hour capacity to daily forage needs
- 300+ head or commercial silage — Consider larger self-propelled harvesters in addition to the 9YDB-100 for harvest logistics
FAQs of Haylage Baler Machine
What tractor horsepower does the 9YDB-100 haylage baler need?
A 70 HP tractor with 540 rpm PTO is the standard match. The acceptable range is 44.1-95.6 kW (60-130 HP). For operations without a suitable tractor, a 37 kW electric motor version is also available.
How many bales can one roll of silage film produce?
With 500 mm film width and 4-6 layers per bale, one standard 1500 m roll of 25 µm silage film produces approximately 25-35 bales on the 9YDB-100. The exact number depends on the number of film layers you apply.
What moisture content is best for baling haylage?
Target 40-60% moisture for proper lactic fermentation. Above 65%, the risk of clostridial fermentation and butyric acid increases. Below 35%, the bale won’t ferment properly and behaves more like dry hay.
Can the 9YDB-100 haylage round baler handle dry hay bales as well?
The machine is designed for haylage (high-moisture wrapped bales). For dry hay below 20% moisture, the wrapping film is not necessary and the 9YDB-100 is overkill. Use a conventional square or round baler for dry hay.
How long does a wrapped bale keep in storage?
Sealed haylage bales keep 12-24 months when film integrity is maintained. Store bales on a well-drained surface, away from sharp objects, and check film periodically for punctures.
What maintenance does the 9YDB-100 require?
Daily: grease the PTO shaft, check film roll, inspect net wrap.
Weekly: check tire pressure, belt tension, and chain lubrication.
Annually: replace hydraulic oil, inspect bearings, and replace the wrapping arm wear parts.
A complete maintenance manual ships with the machine.
