Tractor-Driven Double Film Silage Wrapper
የ 4QM-1200 silage wrapper is a tractor-driven, double-film bale wrapper built for round bales from Φ900 to Φ1100 mm in diameter and 850 to 1000 mm tall, weighing up to 500 kg. Mounted on a standard 3-point hitch and powered by the tractor’s ≥90 HP hydraulic system (30 L/min flow at 12 V), it applies two 500 mm stretch film rolls simultaneously to seal bales airtight for anaerobic fermentation. Pair it with the Taizy silage baler or run it as a stand-alone wrapper next to your 4QZ-M30 / 4QZ-M2600 harvester for a continuous cut → bale → wrap workflow in the field.
The 4QM-1200 is designed for medium and large livestock operations in markets where round silage bales are the standard—Kenya, South Africa, Pakistan, Australia, the UK, Ireland, Russia, and Indonesia. Read on for specifications, working principle, harvester pairing, maintenance, and FAQs.

What Is a Silage Wrapper?
ሀ silage wrapper (also called a round bale wrapper or stretch-film bale wrapper) is a machine that seals round silage bales inside airtight plastic film so they can ferment anaerobically. Once wrapped, the bale becomes a sealed environment where lactic acid bacteria convert sugars into lactic acid. This preserves forage nutrients for 12–24 months without refrigeration or preservatives.
Unlike a የሃይድሮሊክ silage baler that compacts chopped forage into a dense bale, the 4QM-1200 silage wrapper only wraps an existing round bale. This division of labor lets you pick the baler separately and run the wrapper at any point along the workflow—at the harvester, at the storage site, or as a mobile unit following the tractor.
Key Features of the 4QM-1200 Double Film Silage Wrapper
- Double 500 mm Film Rolls — Two stretch film rolls run simultaneously, halving wrap time compared with single-roll wrappers and producing a tighter, more uniform seal around the bale.
- 3-Point Hitch Mounting — Standard Cat I / Cat II 3-point linkage means the wrapper attaches to almost any agricultural tractor in seconds. No trailer, no extra hitch hardware.
- Electro-Hydraulic Automatic Control — A 12 V control box automates rotation speed, film overlap ratio, and cut-and-tie. The operator simply loads the bale, presses start, and removes the wrapped bale at the end of the cycle.
- Tractor-Driven Hydraulics (≥90 HP, 30 L/min) — Draws power directly from the tractor’s remote hydraulic outlets. No separate diesel engine, no electric motor—lower acquisition cost and simpler maintenance.
- Φ900–1100 mm Bale Compatibility — Covers the most common round bale sizes produced by mid-range balers, including the 9YDB-100 haylage baler (Φ1000 × 850 mm, 400–500 kg).
- Mobile Field Operation — With the wrapper on the 3-point hitch, you can move between fields with the tractor—no flatbed truck or low-loader required. Cut and wrap in the same paddock to minimize bale handling.
- Robust 620 kg Frame — Heavy steel frame handles the vibration of continuous baling/wrapping cycles and absorbs the weight of up to 500 kg bales without flexing.
- Field-Friendly Footprint (2600 × 1800 × 2200 mm) — Compact dimensions fit through standard farm gates and trailer lanes without modification.
How the 4QM-1200 Silage Wrapper Works
- Load the bale — Place a round bale (Φ900–1100 mm, ≤500 kg) onto the wrapping table. The 4QM-1200’s hydraulically lowered cradle accepts bales directly from the baler discharge or by hand.
- Engage the hydraulics — Connect the two hydraulic hoses to the tractor’s remote outlets and the 12 V power lead to the tractor’s battery.
- Set film layers — Choose 4, 6, or 8 layers on the control panel. Most operations use 4–6 layers for standard corn silage and 6–8 layers for high-moisture haylage or long-term storage.
- Start the cycle — The wrapping table rotates the bale while two film dispensers apply 500 mm stretch film with a 50% pre-stretch and 50% overlap.
- Cut and seal — At the end of the cycle, the film is automatically cut and tucked. The cradle lowers for bale discharge.
- Store or transport — Move the wrapped bale to the storage pad or directly onto a flatbed. Sealed bales keep 12–24 months without nutrient loss.
Total cycle time on the 4QM-1200 is typically 60–120 seconds per bale at 6 layers, depending on rotation speed and film overlap settings.
Pairing the 4QM-1200 with the 4QZ-M30 and 4QZ-M2600 Harvesters
The 4QM-1200 silage wrapper was designed to work alongside Taizy’s 4QZ-M30 እና 4QZ-M2600 self-propelled silage harvesters. In a typical deployment:
- Cut — The 4QZ-M30 / 4QZ-M2600 chops whole-plant corn, alfalfa, or sorghum and discharges it into a waiting trailer or baler.
- Bale — A separate round baler (e.g., Taizy TZ-55-52 or 9YDB-100) compresses the chopped forage into Φ1000 mm round bales.
- Wrap — The 4QM-1200 follows the baling output on the 3-point hitch of a second tractor. Bales are wrapped within minutes of being produced, eliminating oxygen exposure and locking in freshness.
Locking in freshness at the field edge (rather than transporting unwrapped bales to a central wrapping site) reduces film damage, cuts handling, and helps the forage hit the 60–70% moisture target for optimal lactic fermentation before any aerobic spoilage can start.
Applications: Forage Types for the 4QM-1200 Silage Wrapper
| Forage | Recommended Film Layers | Target Moisture | Best Use |
|---|---|---|---|
| Whole-plant corn | 4–6 | 60–70% | Dairy and beef cattle |
| Alfalfa | 6–8 | 50–60% | High-protein dairy feed |
| Sorghum / millet | 4–6 | 60–70% | Drought-resistant forage |
| Oat haylage | 6 | 50–60% | Sheep and goat feed |
| Mixed grass–legume | 6 | 50–65% | General livestock operations |
| Brewer’s grains / distillers grains | 6–8 | 65–75% | Byproduct preservation |
Tractor and Power Requirements
The 4QM-1200 silage wrapper is a powered implement—almost all energy comes from the tractor. To run it correctly:
- Tractor horsepower: Minimum 90 HP at the PTO. Tractors below this rating cannot supply enough hydraulic flow to drive the wrapping rotation under load.
- Hydraulic flow: 30 L/min at standard remote-valve pressure (180–200 bar). Tractors with load-sensing hydraulics may need the flow pre-set.
- Working voltage: 12 V DC drawn from the tractor’s battery for the electro-hydraulic control box. A fused lead is included.
- Hitch: Standard 3-point linkage, Cat I or Cat II. Check the tractor’s lift capacity (≥900 kg) for safe handling with a loaded bale.
- Hydraulic remotes: Two double-acting remote valves (one for rotation, one for table lift).
How to Choose the Right Silage Wrapper
When evaluating silage wrappers for your operation, work through these five checks before committing:
- Match your bale size. Pick a wrapper whose accepted bale diameter and weight cover the output of your baler. The 4QM-1200 covers Φ900–1100 mm bales up to 500 kg—the most common size for mid-range round balers.
- Count the film rolls. Single-roll wrappers are cheaper; double-roll wrappers (like the 4QM-1200) finish each bale faster and produce a tighter seal because film layers are applied simultaneously from both sides.
- Check tractor compatibility. Wrapper horsepower and hydraulic flow requirements must match your tractor. A 90 HP tractor is the minimum for the 4QM-1200; smaller tractors need an electric or diesel-powered wrapper instead.
- Decide on mobility. Tractor-mounted wrappers (3-point hitch) travel with the tractor across fields. Trailed or stationary wrappers need a flatbed truck to move between sites.
- Consider automation level. Fully automatic wrappers (like the 4QM-1200) cut film and tuck at the end of the cycle without manual help. Manual or semi-auto wrappers require the operator to cut film between bales.
Maintenance and Troubleshooting
| Interval | Maintenance Task |
|---|---|
| Daily | Grease the wrapping table bearings; check film roll tension; inspect film for tears; verify 12 V control power. |
| Weekly | Check hydraulic hose connections for leaks; clean the control panel; inspect film dispenser gears. |
| Monthly | Tighten 3-point hitch pins; replace stretched or damaged film rollers; check electrical connectors for corrosion. |
| Seasonally | Flush and replace hydraulic oil; inspect the rotation motor; replace the film cut-and-tie blade if dull. |
| Annually | Replace hydraulic seals as preventive maintenance; repaint any chipped surfaces to prevent rust; recalibrate the control panel. |
For persistent issues—uneven film overlap, slow rotation, film tearing at the dispenser—refer to the operator’s manual or contact Taizy support. Most issues on the 4QM-1200 trace back to incorrect film roll loading, low hydraulic flow, or a blunt cut-and-tie blade.
FAQs of the 4QM-1200 Silage Wrapper
What is a silage wrapper used for?
A silage wrapper seals round forage bales inside airtight stretch film so they ferment anaerobically. Wrapped bales preserve nutrients for 12–24 months without refrigeration or chemical preservatives.
What size round bales does the 4QM-1200 handle?
The 4QM-1200 wraps round bales from Φ900 to Φ1100 mm in diameter and 850 to 1000 mm in height, up to 500 kg. This covers the most common round bale sizes produced by mid-range balers such as the 9YDB-100 haylage baler.
What tractor do I need for the 4QM-1200?
You need a tractor of at least 90 HP with two double-acting hydraulic remote valves delivering 30 L/min and a 12 V electrical outlet for the control box. A standard Cat I or Cat II 3-point hitch is required.
How many layers of film does the 4QM-1200 apply?
The 4QM-1200 can apply 4, 6, or 8 layers of 500 mm stretch film per bale. For standard corn silage at 60–70% moisture, 4–6 layers is typical. For high-moisture haylage or long-term storage beyond 12 months, use 6–8 layers.
Can the 4QM-1200 work with the 4QZ-M30 or 4QZ-M2600 harvester?
Yes. The 4QM-1200 was designed to follow the 4QZ-M30 and 4QZ-M2600 self-propelled silage harvesters in the field. The harvester cuts and discharges forage; a baler produces round bales; the 4QM-1200 wraps the bales on the 3-point hitch of a second tractor at the field edge.
How much stretch film does one bale use?
At 6 layers and 50% pre-stretch, a Φ1000 × 850 mm round bale consumes roughly 0.4–0.5 kg of 500 mm stretch film. A standard 25 µm × 1500 m roll wraps about 60–80 bales on the 4QM-1200.
How long do wrapped silage bales keep?
Properly wrapped bales with no film damage keep 12–24 months. Store bales on well-drained ground away from sharp objects, check film periodically for punctures, and avoid stacking bales more than two high to prevent crushing the bottom layer.
What maintenance does the 4QM-1200 need?
Daily: grease wrapping table bearings and check film roll tension. Weekly: inspect hydraulic hoses for leaks. Seasonally: flush and replace hydraulic oil, inspect the rotation motor. Annually: replace hydraulic seals as preventive maintenance and recalibrate the control panel. The full maintenance schedule is in the operator’s manual.
