9YCM-850 Silageballenpresse mit Wickelfunktion | 30–40 Ballen/Std.
Der 9YCM-850 silage baler wrapper compresses fresh, high-moisture crop material and seals it in stretch film in a single continuous field pass — no stopping, no second machine, no exposure window for oxygen to enter the bale. At 30 to 40 sealed bales per hour, it is the highest-throughput one-pass silage preservation solution in our equipment range, designed for dairy farms running large-scale grass and corn silage programs, custom-wrap contractors servicing multiple clients per week, and beef operations transitioning from dry hay to fermented silage for winter feeding.
The Silage Science: Why Minutes Matter Between Baling and Wrapping
The 9YCM-850's integrated design is not a convenience feature — it's a direct response to the fermentation biology of high-moisture forage. Understanding why the wrapper must follow the baler immediately, rather than after a delay, explains why an integrated machine produces measurably better silage than a two-machine workflow with a time gap between baling and wrapping.
Oxygen is trapped between the crop material. Aerobic respiration by plant cells and mold spores begins, consuming water-soluble carbohydrates — the primary fuel for desirable lactic acid bacteria.
Yeast and mold activity accelerates. CO₂ generation increases temperature inside the unwrapped bale. Each 1°C rise above 30°C in the fermentation phase reduces final silage dry matter content by 0.3–0.5 percentage points.
Oxygen is excluded within seconds of bale completion. Residual oxygen is consumed by aerobic bacteria within 24–48 hours. LAB (lactic acid bacteria) achieve anaerobic conditions rapidly, producing the lactic acid that drops pH to 4.0–4.5 and preserves DM at 90–95% of theoretical maximum.
Source basis: USDA National Institute of Food and Agriculture extension recommendations on silage bale wrapping timing. Target wrap gap: under 4 hours from baling; under 60 minutes for maximum DM preservation at high moisture (>70%).
The 9YCM-850 eliminates the exposure window entirely: the bale completes in the fixed chamber, transfers automatically to the integrated wrapper turntable, and is sealed in stretch film in the same field pass — the maximum exposure time between baling completion and seal-start is under 60 seconds during normal operation. This is not achievable with a separate baler-plus-standalone-wrapper workflow, where bales typically sit for 30 minutes to several hours depending on operator capacity and field layout.
Technische Spezifikationen
The 9YCM-850 connects to the tractor via rear three-point hitch, 540 rpm rear PTO, and two rear hydraulic remote outlets (one ½-inch, one ¾-inch). A 12 V DC connection to the tractor's electrical system powers the electronic control panel. Verify all four connection types — PTO, hitch, hydraulics, and 12V — are available on your tractor before ordering.

The Four-Stage Continuous Cycle: Load → Bale → Wrap → Eject
Wrap Film Application Guide: Layers by Crop and Storage Duration
Film layer count is the single operator-controlled variable that has the greatest impact on silage quality during the storage period. Too few layers allow micro-punctures from field debris and UV degradation to admit oxygen over time; too many layers increase film cost beyond what fermentation quality requires. The table below gives the industry-standard recommendations for each major crop type and storage scenario.
| Crop / Material | Moisture at Baling | Min. Film Layers | Storage Duration | Anmerkungen |
|---|---|---|---|---|
| Fresh-cut grass silage | 65–75% | 6 | 6–12 months | Most common use case; 6 layers is the NRCS recommended minimum for full-season outdoor storage |
| Corn silage (whole plant) | 60–68% | 6–8 | 6–18 months | Corn stalk edges can puncture film — 8 layers recommended if stalks are not shredded at harvest |
| Alfalfa / legume silage | 55–65% | 4–6 | 3–8 months | Lower moisture reduces fermentation pressure on wrap; 4 layers sufficient for under 6 months storage |
| High-moisture grain (HMG) | 25–35% | 8 | Up to 18 months | Long storage duration increases UV and mechanical puncture risk; 8 layers mandatory for full-season exposure |
| Hay silage / haylage | 45–60% | 4–6 | 3–6 months | Partially wilted material; higher DM means lower internal gas pressure — 4 layers functional for short-term use |
The 9YCM-850 accepts standard 750 mm × 1,500 m UV-resistant white or black stretch film rolls. White film is preferred for outdoor long-term storage as it reflects solar radiation and reduces internal bale temperature. Black film reduces UV penetration but increases heat absorption in summer. Confirm with your film supplier that the stretch ratio is rated at 50–70% elongation — under-stretched film loses barrier integrity under bale compression.
Who Benefits Most from the One-Pass System
One-Pass vs Two-Machine: The Economics of Integration
The 9YCM-850 replaces two separate machines — a round baler and a standalone bale wrapper. The capital cost comparison is the starting point, but the operating economics over a 5-year season cycle make the integrated argument stronger:
Upstream Equipment: Building a Complete Silage System
The 9YCM-850 processes material that has already been cut and windrow-conditioned upstream. The quality of that upstream operation determines whether the hopper receives a clean, consistent material flow or a problematic one. Three upstream equipment choices matter most:
Mowing Equipment: Clean-cut conditioned material feeds more uniformly into the 9YCM-850 hopper than unconditioned swath. Our Mähgeräte includes disc and sickle-bar mowers for the crop widths and field conditions common to U.S. silage operations.
Windrow Preparation: A properly formed, consistent-density windrow prevents the surge-and-gap feeding pattern that causes bale density variation in the 9YCM-850 chamber. Our hay rake lineup produces uniform windrows from 5 to 12 meters of cut width, matched to the working speeds at which high-moisture silage crops are raked without excessive leaf shatter.
Driveline at 120+ HP: At 88+ kW PTO input, the 9YCM-850 imposes both continuous compaction torque and instantaneous load spikes when dense windrow material surges into the chamber at field speed. A correctly specified high-torque agricultural gearbox in the PTO driveline absorbs those spikes while maintaining consistent conveyor and compaction roller speed — critical because bale density variation across the compaction cycle affects final silage DM content and fermentation uniformity. For the 9YCM-850's 88+ kW input range, the gearbox should be rated for continuous input torque above 1,000 Nm with a peak tolerance of 2,000+ Nm.
Pre-Season Readiness Checklist and Maintenance
The 9YCM-850 combines a baling mechanism, a film delivery system, and an electronic control module — three mechanical sub-systems that each need pre-season verification. Run through this checklist before the first cut of each season:

Häufig gestellte Fragen
How long can sealed bales be stored before feeding?
Well-sealed bales with 6+ layers of UV-resistant film store reliably for 12 to 18 months outdoors. Fermentation completes within 3 to 6 weeks of baling, after which the bale enters stable anaerobic storage. Inspect the exterior of stored bales monthly — any puncture or bird damage should be repaired immediately with repair tape to prevent aerobic spoilage from developing at the damage point.
What film roll dimensions does the 9YCM-850 accept?
Standard 750 mm wide × 1,500 m length rolls at 25 micron nominal thickness. The machine's film arm and pre-stretch rollers are designed for this international standard dimension, which is the most widely stocked silage film specification in North American agricultural supply chains. Using non-standard widths or ultra-thin film (under 22 microns) requires consultation with the U.S. support team before field use.
Does the machine require a separate operator to manage the wrapping section?
No — the electronic control system manages the bale transfer from the baling chamber to the wrapping turntable and initiates the wrap cycle automatically when the completed bale triggers the transfer sensor. The tractor operator controls the machine via the electronic panel in the cab. A second person is not required under normal field conditions, though some operators choose to station a helper to monitor ejected bale condition on the first day of the season.
Can the baling section be used without the wrapper for dry hay baling?
Yes — the baling section operates independently at 540 rpm PTO for conventional dry hay baling. The wrapper can be disengaged via the electronic control panel when producing twine- or net-tied dry hay bales. This makes the 9YCM-850 a dual-purpose machine: silage wrapping during the high-moisture cutting season and conventional baling for the hay cutting season, on the same 120 HP tractor.
How long does assembly take on delivery?
The 9YCM-850 ships partially disassembled for transit. On-farm assembly involves connecting the PTO driveshaft, attaching the hydraulic hoses to the correct tractor outlets (½-inch for the baling function, ¾-inch for the wrapper), connecting the 12V harness, and installing the film roll. Total assembly time is 2 to 3 hours for two operators using the illustrated assembly guide. The U.S. team is available by phone for real-time guidance on the hydraulic connection sequence, which is the most operator-specific step.
What happens if the film runs out mid-field?
The electronic control panel displays the approximate number of wraps remaining based on the bale count versus roll length. The operator receives an alert before the film runs out. When a roll ends, the wrapper pauses, the operator loads a new roll (under 3 minutes with practice), and the cycle resumes. Bales that are partially wrapped when a roll runs out should be immediately completed with a fresh roll or hand-wrapped before storage — do not leave partially wrapped silage bales in the field.
How does the 9YCM-850 compare to purchasing a separate baler and wrapper?
The integrated design reduces total capital cost by 20–30% compared to purchasing a commercial round baler and a standalone bale wrapper separately. Beyond capital cost, it eliminates the second-machine logistics and operator time, reduces DM losses from delayed wrapping, and halves the parts inventory and maintenance overhead. For operations producing more than 500 wrapped bales per season, the DM preservation improvement alone — typically 5 to 10 percentage points over delayed wrapping — recovers a substantial portion of the machine cost in feed value saved within the first two seasons.
Five Silage Producers: Season Results
We milk 320 Holsteins and silage grass is 60% of our basal diet. Before the 9YCM-850 we baled with a standalone baler and wrapped the next morning — always late by 12 to 18 hours. Sample fermentation scoring from our nutritionist showed consistently low lactic acid scores. First season with the 9YCM-850, same grass, same cutting schedule, scores improved significantly. The one-pass seal makes a measurable difference in the finished product we are feeding the herd.
Custom silage wrapping service for 28 client farms in Columbia and Greene counties. The 9YCM-850 made same-day service on every farm possible — before, I had to schedule return trips for wrapping. Client satisfaction improved and I took on six additional farms this season without adding equipment. The 30-to-40-bale-per-hour rate means I can complete a 50-acre grass field in under four hours including moves.
We grow on-farm corn silage for 450 stocker cattle in central Pennsylvania. Switched from a bunker silo to wrapped round bales for the flexibility of opening only what we need each day. The 9YCM-850 completed 380 corn silage bales this fall in two days of field work. No bunker face management, no waste from overheating when opening too large a face, and the per-bale inventory system lets us track our feed budget exactly. Four stars because the 9.9 ft transport height requires careful routing on our county roads.
300-acre certified organic dairy in the Treasure Valley. We bale multiple forage varieties — ryegrass, triticale, and a grass-legume mix — in small lots per variety. The electronic bale counter and ability to pause and label bales by variety makes inventory tracking straightforward for our organic certification records. The dual-use feature, baling conventional dry hay in summer and silage in spring and fall on the same machine, means the 9YCM-850 is active almost all season. Very satisfied.
We run a small goat dairy on 80 acres of mixed perennial pasture in Sonoma County — small cuts of 15 to 25 bales, multiple varieties, strict feed inventory records for our direct-sales marketing. The 9YCM-850 was bought specifically because we could not justify two separate machines on this scale. The integration gives us commercial silage quality on a small-farm volume. The U.S. support team helped us configure the electronic panel for our three different forage programs — excellent pre-purchase consultation.
