700720740 Knife Arm Massey Ferguson MF2270/MF2270XD Big Square Baler for Agriculture Machinery Agricultural Part

The Knife Arm, 700720740 is a core cutting component exclusively developed for the knotter system of AGCO Massey Ferguson 2270/2270XD Big Square Balers—flagship models widely applied in large-scale hay, forage, and straw baling operations. Its main function is to accurately cut baling twine after the knotting cycle is completed: when the baler compacts crop materials into standard big square bales, the knife arm coordinates with the knotter’s tying mechanism. It triggers quickly at the precise moment after the twine is knotted, ensuring the twine is cut cleanly (without fraying or incomplete cutting) and the remaining twine length meets the subsequent baling requirements. This precise cutting directly avoids issues such as uncut twine tangling the next bale, uneven twine ends affecting knotting, or bales being connected by uncut twine—problems that often lead to baler jams, field work delays, and reduced bale quality.

High Durability

Designed to withstand the harsh operating conditions of large-square baling (frequent high-speed cutting, contact with hard crop residues, and exposure to dust/moisture), the Knife Arm, 700720740 is made of high-strength alloy steel (reinforced with heat treatment to enhance hardness and toughness). It undergoes a professional multi-step surface treatment process (wear-resistant quenching + anti-rust plating) that forms a protective layer against:

Premature blunting caused by continuous friction and cutting of baling twine (especially high-tensile twine) during high-frequency baling cycles;

Corrosion and rust from long-term exposure to field dew, crop moisture, or dust accumulation;

Impact damage from accidental contact with hard impurities (such as small stones or branches) mixed in crops.Even after completing thousands of cutting cycles (equivalent to a full farming season’s workload), the knife arm maintains its original sharpness, structural stability, and cutting accuracy—reducing the need for frequent sharpening or replacement, and minimizing unplanned downtime for the Massey Ferguson 2270/2270XD.

High Compatibility

Meticulously engineered to comply with AGCO’s original equipment (OE) specifications for the Massey Ferguson 2270/2270XD Big Square Baler, the Knife Arm, 700720740 ensures seamless integration with the baler’s existing knotter assembly. No modifications are required to the machine’s knotter frame, adjacent components (e.g., twine guides, knotting hooks), or mounting structure. Key design details are precisely matched to the original part:

Overall length, width, and thickness (ensures perfect fit with the knotter’s movement track and installation space);

Cutting edge angle and position (aligns exactly with the baler’s twine cutting path to avoid missed cuts);

Mounting hole size, position, and quantity (compatible with the OE fasteners of the 2270/2270XD).This “drop-in” compatibility enables quick, tool-friendly replacement (even in field settings) and preserves the baler’s original knotting and cutting accuracy—avoiding malfunctions such as twine jams or incomplete knots caused by ill-fitting aftermarket knife arms.

Stable Performance

The Knife Arm, 700720740 delivers consistent cutting performance even under the most demanding baling scenarios—including processing thick, high-tension baling twine (e.g., polyester twine, high-density polypropylene twine) or operating at the 2270/2270XD’s maximum baling speed (up to 40 bales per hour). Its optimized design features:

A high-hardness cutting edge (maintains sharpness for long periods, avoiding incomplete twine cutting due to blunting);

Balanced structural design (minimizes vibration during rapid cutting movements, ensuring stable contact with twine);

Strong connection points (resists deformation or loosening under the impact force of high-speed cutting).By eliminating issues such as frayed twine ends, missed cuts, or delayed cutting, the knife arm sustains the baler’s operational efficiency—avoiding bale quality defects (e.g., unfastened bales, twine tangles) and production losses during peak harvesting seasons.

High Precision

Produced using advanced CNC machining technology (specifically calibrated to AGCO’s OE tolerance standards), the Knife Arm, 700720740 undergoes strict quality inspection at every manufacturing stage:

Dimensional verification (overall size, mounting hole position, and cutting edge angle checked to ±0.03mm accuracy);

Cutting edge sharpness testing (ensures uniform sharpness across the entire edge to prevent uneven twine cutting);

Structural strength validation (tests resistance to deformation and impact to meet the 2270/2270XD’s cutting force requirements).This high precision ensures two critical outcomes:

Consistent cutting quality (guarantees clean twine ends, which is essential for smooth knotting in the next cycle);

Perfect synchronization with the 2270/2270XD’s knotter timing (avoids cutting delays or premature cutting that render knots invalid).

Excellent Cost-Effectiveness

The Knife Arm, 700720740 delivers long-term economic value by combining durability, reliability, and OE-grade performance—addressing the key cost drivers for Massey Ferguson 2270/2270XD operators:

Reduced replacement and maintenance costs: Its wear-resistant and high-hardness design lasts 2–3 times longer than generic aftermarket knife arms, eliminating frequent purchases and sharpening expenses;

Avoided secondary damage: By preventing twine jams or knotter malfunctions caused by poor cutting, it protects high-value knotter components (e.g., knotting hooks, drive gears) from costly repairs;

Minimized downtime losses: During peak baling seasons, even 1 hour of downtime due to knife arm failure can lead to over $1,000 in lost crop harvesting—its stable performance avoids these losses.Compared to low-quality alternatives (which often blunt or deform mid-season), this knife arm lowers the 2270/2270XD’s total operational and maintenance costs over multiple farming cycles.

Large Inventory & Fast Delivery

We maintain a dedicated, large-scale inventory of the Knife Arm, 700720740—specifically stocked to meet urgent replacement needs during peak baling seasons (spring hay, fall straw). Our logistics network is optimized for agricultural customers, offering:
