9YCM-850 Baler Wrapper Combination — Automatic Round Silage Baler & Wrapper in One Pass
The 9YCM-850 is a tractor-mounted baler wrapper combination that compresses fresh forage into φ85–90 × 85 cm round bales and wraps them airtight in a single continuous operation. Running at 540 rpm PTO and matched to tractors of ≥120 hp, it delivers 30–40 wrapped bales per hour with one operator — eliminating the time lag between baling and wrapping that is responsible for the majority of surface spoilage in two-machine systems. Designed for grass silage, haylage, corn stover, alfalfa, and mixed legume forages, it targets livestock operations, custom forage contractors, and distributors sourcing silage baler and wrapper for sale for commercial fleet use.
What the 9YCM-850 Baler Wrapper Combination Does — and What It Solves
In traditional two-step forage systems, a round baler produces bales that sit exposed in the field before a separate wrapper unit processes them. Each hour of exposure after baling allows oxygen ingress, surface heating, and mold colony establishment. Studies in silage fermentation management consistently point to the interval between baling and wrapping as the primary control variable for aerobic spoilage — with every additional hour of delay increasing dry matter loss by 0.5–1.5% at the bale surface.
The 9YCM-850 eliminates this interval entirely. The bale chamber compresses the crop into a dense, consistent round bale; the moment the tailgate opens, the bale transfers directly onto the integrated wrapping table and receives its stretch film layers before being ejected to the field. The entire bale-to-wrapped cycle repeats at 30–40 bales per hour, giving operators a throughput rate competitive with separate two-machine crews while requiring only one tractor and one driver.
The electronic control system automates film cutting, bale transfer timing, and wrapping rotation, keeping operator decisions focused on driving and swath management rather than machine sequencing. A 2.5 m³ hopper volume handles heavy swath pickups without bunching, and the 12V DC electrical requirement integrates directly with standard tractor cab electrics — no external power source needed.
Each completed bale — 0.48–0.54 m³ in volume, sealed in multiple stretch film layers — creates an anaerobic fermentation environment that preserves forage nutritional value for 12–18 months under normal storage conditions. For dairy and beef operations, this means reliable access to high-energy winter feed from summer grass cuts without the DM losses associated with pit silage or open-clamp storage systems.

Why the 9YCM-850 Baler Wrapper Combination Outperforms Two-Machine Systems
Zero Bale-to-Wrap Delay
Baling and wrapping happen in immediate sequence on the same machine. There is no window for oxygen to enter the bale surface. This alone accounts for the 5–10% DM loss reduction over two-machine workflows documented in commercial forage trials.
30–40 Bales/Hour — One Operator
At 40 bales per hour and a bale volume of 0.48–0.54 m³, a single shift produces enough wrapped silage to feed a 200-head beef herd through a full winter. No second machine, no second driver, no second fuel cost.
Electronic Control System — Reduced Operator Error
Film cut, bale transfer, and wrapping rotation are automated through the onboard ECS. The operator sets parameters once at field start; the machine executes the same wrap count on every bale. This consistency is critical for maintaining airtight seals across a full day’s run.
540 rpm PTO — Standard Tractor Compatibility
Runs off any 120+ hp tractor with a standard 540 rpm PTO output. No modified gearbox, no specialized tractor equipment. Hydraulic connections use common 1/2 in and 3/4 in ports available on virtually all mid-range agricultural tractors.
Consistent φ85–90 × 85 cm Bale Geometry
Uniform bale size simplifies storage stacking (standard 3-bale-high pyramid), handling with front loaders, and feeding calculations. A predictable bale volume means consistent feed ration planning without bale-to-bale variation.
12V DC Integration — No External Power
All electronic control functions draw from the standard tractor 12V DC supply. No generator, no additional battery pack. Field setup involves PTO connection, two hydraulic couplings, and a 12V plug — typical hookup time under 15 minutes.
Where the 9YCM-850 Baler Wrapper Combination Works
The machine handles a range of forage types and farm setups, making it suitable across diverse livestock and cropping systems:
- Grass and Haylage Operations: First and second cut grass at 40–65% moisture is the primary application. The 2.5 m³ hopper handles dense windrows from high-yield grass fields without feed-rate inconsistency.
- Corn Stover / Maize Silage: Whole-plant corn silage and post-harvest stover can be processed directly. Pre-chopping to 5–15 cm lengths with a forage harvester before baling improves compression density and fermentation uniformity.
- Alfalfa and Legume Crops: Alfalfa at the early bud stage (55–65% moisture) produces high-protein silage when wrapped immediately. The zero-delay baling-to-wrapping workflow is particularly important for alfalfa, which oxidizes faster than grass.
- Custom Forage Contracting: At 30–40 bales per hour, contractors running the 9YCM-850 can cover multiple farms per day during peak grass harvest windows. One machine replaces a baler-plus-wrapper pair, reducing equipment transport logistics by 50%.
- Dairy and Beef Feed Programs: Operations feeding total mixed rations (TMR) benefit from the consistent 0.48–0.54 m³ bale volume, which allows precise silage inclusion calculations per feeding period without weighing every bale.
How to Make Round Silage Bales with the 9YCM-850
Making high-quality wrapped silage bales requires getting five steps right. Here is how the process works from field to stored bale, and where the 9YCM-850 fits in:
Mow at the Right Growth Stage
Cut grass at early heading (for ryegrass) or early bud stage (for legumes). Cutting at the right growth stage sets the energy content of the final silage. A disc mower or drum mower leaves a 5–8 cm stubble height to protect the sward.
Wilt to Target Moisture (40–65%)
Tedding spreads the cut crop for faster moisture loss. Target 40–65% moisture before baling — too dry and fermentation stalls; too wet and effluent leaches from the bale, carrying nutrients with it. Wilting to 55% typically takes 12–24 hours in good conditions.
Rake into Windrows
A rotary rake or wheel rake consolidates the wilted crop into a consistent windrow width matched to the baler pickup. Even windrow density is the single biggest factor controlling bale shape uniformity — poor windrows produce lopsided bales that wrap unevenly.
Bale & Wrap in One Pass — 9YCM-850
This is where the 9YCM-850 Baler Wrapper Combination replaces two separate machines. The pickup collects the windrow, the bale chamber compresses it to φ85–90 × 85 cm, and the integrated wrapping unit applies stretch film layers and cuts automatically — all before the next windrow section. At 30–40 bales per hour, this step processes an entire day’s grass cut before afternoon dew sets in.
Store on Firm, Shaded Ground
Wrapped bales are moved to a storage site on firm, well-drained ground. Stack no more than 3 high to avoid bale deformation under load. Keep out of direct sunlight — UV degrades stretch film and risks puncture. Under these conditions, bale silage stores reliably for 12–18 months.
