9YG-1.25A Round Baler
The Jummos 9YG-1.25A Round Baler is a traction type round baler designed to pick up, compress, and net wrap hay, straw, and silage into dense Φ1300 x 1250 mm round bales. As a round baler manufacturer in China, Jummos builds this model with a 2150mm spring tine pickup, an 18-roller forming chamber, and sensor-controlled bale density for consistent bale weight across the field.
It combines a finger bar and roller feeding mechanism with a roller type bale chamber, delivering an output of 40 to 100 bales per hour at working speeds of 5 to 35 km/h. The 9YG-1.25A matches tractors of 75 kW and above, with OEM supply and customization available for distributors and brand partners.
Key Benefits
- Sensor-controlled bale density – Density is regulated by sensor rather than by operator feel, keeping bales at a consistent 100 to 200 kg/m³
- 18-roller forming chamber – Φ222 mm rollers drive the forage into a tight, well-shaped bale that holds its form in storage and transport
- 2150mm spring tine pickup – A wide pickup clears the swath in fewer passes and reduces material left in the field
- Finger bar and roller feeding – Combined feeding keeps material moving evenly into the chamber and limits blockage on heavy crops
- High output – Productivity of 40 to 100 bales per hour supports tight harvest windows and contract work
- Net wrap binding – Uses 2000 m x 1.25 m net rolls for fast, secure wrapping and better weather resistance than twine
- Wide PTO range – Accepts 540 to 1000 r/min output, so the baler pairs with a broader range of tractors already in the fleet
- Stable towing platform – A 2450 mm wheel track and 4472 kg structure mass keep the machine steady on slopes and uneven ground
- Traction type mounting – Tows behind the tractor, freeing the three-point linkage and simplifying transport between fields
- OEM and customization available – Color, configuration, and branding can be tailored for distributors and brand partners

Applications & Use Cases
- Hay baling – Forms dense round bales of grass, alfalfa, and mixed forage ready for stacking and long-term storage
- Straw collection – Clears wheat, rice, and corn straw from the field for bedding, feed, or resale
- Silage baling – Produces net-wrapped bales at 100 to 200 kg/m³ that move straight to a bale wrapper for fermentation
- Livestock and dairy farms – Consistent bale weight simplifies ration planning and feed inventory
- Custom baling contractors – Output of up to 100 bales per hour and a 5 to 35 km/h working range suit paid work across multiple properties
- Mixed tractor fleets – The 540 to 1000 r/min PTO range lets one baler work behind different tractors on the same farm
Operation & Setup Notes
- Pair the baler with a tractor rated at 75 kW or above and confirm the PTO output falls within the 540 to 1000 r/min range
- Hitch the drawbar squarely and check that the driveline has clearance through the full turning arc before starting work
- Set pickup height to the crop and ground conditions so the spring tines gather cleanly without striking soil
- Load net wrap rolls of 2000 m x 1.25 m and verify the wrapping mechanism feeds correctly before the first bale
- Adjust the density sensor setting to the target bale density between 100 and 200 kg/m³ for the crop being baled
- Allow for overall dimensions of 4400 x 2850 x 2400 mm and a 4472 kg structure mass when planning road transport and shed storage
- Inspect rollers, bearings, chains, and pickup tines at regular service intervals to protect bale quality and extend machine life
Frequently Asked Questions
What bale size does the 9YG-1.25A produce?
The machine forms round bales measuring Φ1300 x 1250 mm, produced in a roller type chamber with a Φ1200 mm chamber diameter and 1250 mm chamber width.
What tractor power is required?
Matched power is 75 kW or above, with a power output shaft speed between 540 and 1000 r/min. The wide PTO range allows the baler to work behind more than one tractor in a mixed fleet.
How is bale density controlled?
Bale density is sensor controlled, holding output between 100 and 200 kg/m³. Sensor control removes guesswork from the operator and keeps bale weight consistent across the field.
How many bales per hour can it produce?
Productivity is 40 to 100 bales per hour depending on crop volume, moisture, swath density, and working speed, which ranges from 5 to 35 km/h.
Does it use net wrap or twine?
The 9YG-1.25A binds with net wrap, using rolls of 2000 m x 1.25 m. Net wrap seals the bale surface faster than twine and gives better protection against weather during outdoor storage.
Can it handle silage as well as dry hay?
Yes. The 18-roller chamber and sensor-controlled density produce bales dense enough for silage, and net-wrapped bales can be moved directly to a bale wrapper for fermentation.
Is OEM or customization available?
Yes. Color, configuration, and branding can be adapted for your operation or distribution brand, and OEM supply is available. Contact the Jummos sales team to discuss your requirements.
