9YJS-2.2C Straw Cutting Square Baler
The Jummos 9YJS-2.2C Double-blade Straw Cutting and Rubbing Baler is a traction type square baler that cuts, picks up, rubs, compresses, and ties crop straw into neat square bales in a single pass. As a square baler manufacturer in China, Jummos builds this model with a 2200mm pickup, a front hammer claw and rear flick knife feeder, and twin D type knotters for continuous automatic rope bundling.
Unlike a standard pickup baler, the 9YJS-2.2C handles straw that is still standing in the field as well as straw that is laying or scattered, which makes it well suited to corn, wheat, and cotton residue collection after harvest. Color and configuration can be customized, with OEM supply available for distributors and brand partners.
Key Benefits
- Cuts and bales in one pass – Harvests straw from corn, wheat, cotton, and other crops, handling upright, laying, and scattered material without a separate cutting operation
- Double-blade cutting and rubbing action – Front hammer claw and rear flick knife work together to cut and rub the straw before it reaches the chamber, improving feed quality and bale consistency
- Low soil content in the bale – A mesh screen type material collection chamber separates soil from straw, producing cleaner bales for feed and processing use
- Twin D type knotters – Two knotters tie each bale with automatic rope bundling, reducing missed ties and stoppages during long working days
- Independent damping device – Absorbs shock loads across uneven ground and protects the drivetrain and frame
- Suspended header – Follows ground contours instead of digging in, extending service duration of the cutting components
- Neat, stackable square bales – A 450 x 360 mm compression chamber section produces regular bales that stack tightly on trailers and in storage
- Optional automatic lubrication – A centralized lubrication system dispenses grease automatically, improving sealing, cutting wear part consumption, and extending equipment life
- Traction coupling – Tows behind the tractor and matches 75 kW and above at 720 r/min PTO speed
- OEM and customization available – Configuration, color, and branding can be tailored for distributors and brand partners

Applications & Use Cases
- Corn straw collection – Cuts and bales standing or flattened corn stover directly after grain harvest, clearing the field for the next crop
- Wheat and rice straw baling – Gathers laying and scattered straw into square bales for feed, bedding, or industrial supply
- Cotton stalk handling – Processes tougher cotton residue that ordinary pickup balers struggle to collect
- Feed and forage supply – The mesh screen collection chamber keeps soil out of the bale, which matters when straw is destined for livestock rations
- Biomass and board industries – Cleaner square bales are easier to transport, store, and feed into biomass fuel or particle board processing lines
- Contractors and cooperatives – Traction coupling and a 2200mm working width suit operators covering large areas of post-harvest residue
Operation & Setup Notes
- Match the baler with a tractor rated 75 kW or above and confirm the power output shaft speed is set to 720 r/min before starting work
- Check that the drawbar and driveline have clearance through the full turning arc, since working length reaches 5960 mm
- Set the suspended header to the correct working height so the hammer claw cuts cleanly without picking up excess soil
- Inspect both D type knotters and thread the bundling rope correctly before the first bale of the day
- Allow for working state dimensions of 5960 x 2575 x 1750 mm when planning road transport and shed storage
- Fit the optional centralized lubrication system if the machine will run long shifts, then verify grease is reaching all lubrication points
- Clean the mesh screen collection chamber regularly to keep soil separation working as intended
- Check knives, hammer claws, and drive components at scheduled intervals and replace wearing parts before they affect bale quality
Frequently Asked Questions
What crops can the 9YJS-2.2C handle?
It is used mainly for straw from corn, wheat, cotton, and similar crops. The machine cuts and picks up straw that is upright, laying, or scattered across the field, then rubs, compresses, and ties it into square bales.
How is this different from a normal pickup baler?
A standard baler only collects material that has already been cut and windrowed. The 9YJS-2.2C carries a double-blade cutting and rubbing system, so it can take standing straw straight from the field and bale it in the same pass.
What bale section does it produce?
The compression chamber has a section size of 450 x 360 mm, producing regular square bales that stack efficiently for transport and storage.
How does the machine keep soil out of the bale?
Material and soil separation is handled by a mesh screen type material collection chamber. Soil passes through the screen instead of entering the chamber, so bales come out with low soil content.
What tractor is required?
Matched power is 75 kW and above, with the tractor power output shaft running at 720 r/min. The baler uses traction coupling and tows behind the tractor.
How are bales tied?
Bundling is automatic and uses rope, tied by two D type knotters working together for a secure bind on every bale.
Is an automatic lubrication system available?
Yes. A centralized automatic lubrication system is offered as an option. It dispenses grease automatically for better sealing and lubrication, which reduces wearing part consumption and extends equipment service life.
Is OEM or customization available?
Yes. Configuration, color, and branding can be adapted to your operation or distribution brand, and OEM supply is available. Contact the Jummos sales team to discuss your requirements.
