SHEAR BOLT ARM AGCO Part Number 700119303 for Massey Ferguson 1839/1840 Small Balers

Product Advantage

The SHEAR BOLT ARM, AGCO Part Number 700119303 is a heavy-duty, load-bearing structural component custom-engineered for AGCO Massey Ferguson 1839/1840 Small Balers—high-efficiency models widely trusted for small-square baling of hay, forage, and straw in commercial farms, family orchards, and rural contracting operations. As a critical link in the baler’s shear protection system, its core function is to secure the shear bolt assembly, transmit dynamic baling forces to the machine’s frame, and act as a fail-safe interface to protect high-value components during overload conditions. During the baling cycle, the arm stabilizes the shear bolt’s position under the plunger’s repetitive compressive thrust, ensures uniform force distribution across the bolt, and triggers controlled shear failure of the bolt when the load exceeds safe limits—preventing catastrophic damage to the baler’s feed mechanism, knotter, and plunger assembly. This precision-engineered design directly eliminates common operational risks such as frame deformation, shear bolt misalignment, and unplanned mechanical failures—issues that cause costly downtime, disrupt harvesting schedules, and require expensive repairs to core baler sub-systems.

High Durability

Engineered to withstand the extreme operational stresses of small-square baling—including constant dynamic loading, exposure to crop debris, dust, moisture, and occasional overload impacts—the SHEAR BOLT ARM 700119303 is crafted from premium high-tensile alloy steel (subjected to quenching and tempering for superior hardness, tensile strength, and impact resistance). It also features a dual-protection design to maximize service life in harsh agricultural environments: A corrosion-resistant zinc-plated surface coating that shields the arm from rust and oxidation caused by morning dew, rain, or contact with moist crop materials, preventing surface degradation and material fatigue over extended use; A precision-forged and CNC-machined structural profile with reinforced stress points, ensuring the arm maintains its structural integrity even under repeated cyclic loading and occasional overload events. Even after supporting tens of thousands of baling cycles across multiple farming seasons, the shear bolt arm retains its original dimensional accuracy, load-bearing capacity, and structural stability. This exceptional durability minimizes the need for frequent replacements and drastically cuts unplanned downtime for Massey Ferguson 1839/1840 balers.

High Compatibility

Meticulously designed to meet AGCO’s original equipment (OE) specifications for the Massey Ferguson 1839/1840 Small Balers, the SHEAR BOLT ARM 700119303 ensures seamless integration with the baler’s existing shear protection and force transmission systems. No modifications to the machine’s frame, adjacent components (e.g., shear bolts, pivot brackets, or plunger linkages), or mounting positions are required. Key design parameters are precision-matched to the original part: Mounting hole spacing and diameter: Calibrated to fit the balers’ frame mounting points and shear bolt assemblies without slack or interference, ensuring perfect alignment under peak load conditions; Structural profile and thickness: Matches the original arm’s design to maintain consistent force transmission paths and fail-safe shear bolt activation thresholds; Shear bolt retaining groove dimensions: Aligns with OE specifications to secure the shear bolt in place, preventing axial displacement during the baling cycle. This “drop-in” compatibility enables fast, tool-friendly replacement—even in remote field environments—and preserves the baler’s original operational precision, eliminating malfunctions caused by ill-fitting aftermarket arms (e.g., premature shear bolt failure, excessive vibration, or damage to mating components).

Stable Performance

The SHEAR BOLT ARM 700119303 delivers consistent, reliable performance even under extreme baling conditions—such as processing dense, high-moisture crops (e.g., wet alfalfa, heavy ryegrass) or operating at the balers’ maximum working speed. Its optimized design incorporates three critical performance features: High-tensile alloy steel construction: Withstands the repetitive dynamic loads generated by the baler’s plunger and feed system, preventing bending, deformation, or fracture even under peak operational stress; Precision-machined shear bolt interface: Ensures the shear bolt is held in a fixed, stable position, guaranteeing predictable, controlled failure when overload occurs to protect core baler components; Corrosion-resistant coating: Maintains structural integrity and performance consistency in humid, dusty, or corrosive environments, avoiding performance degradation caused by rust or debris accumulation. By stabilizing the shear bolt assembly, maintaining consistent force transmission, and enabling fail-safe overload protection, the arm sustains the baler’s operational efficiency—avoiding bale quality defects (e.g., uneven density, unfastened bales) and production losses during critical harvesting windows.

High Precision

Produced using advanced hot forging and CNC precision machining (calibrated to AGCO’s strict OE tolerance standards of ±0.002 inches), the SHEAR BOLT ARM 700119303 undergoes rigorous quality inspection at every manufacturing stage: Dimensional verification: Mounting hole spacing, structural thickness, and shear bolt groove dimensions are checked via high-precision coordinate measuring machines (CMM) for absolute accuracy; Tensile strength testing: Validates the arm’s ability to withstand specified static and dynamic loads without deformation, ensuring compliance with OE performance requirements; Surface finish inspection: Measured via profilometry to guarantee a smooth contact surface that minimizes wear on mating shear bolts and frame components. This high precision achieves two key outcomes: Consistent mechanical synchronization: Ensures the baler’s shear protection system operates in perfect harmony with the plunger and feed mechanism, maintaining bale uniformity and knotter accuracy; Extended service life of mating components: Reduces abrasive wear on shear bolts and frame mounting points, lowering the overall maintenance costs of the 1839/1840 balers.

Excellent Cost-Effectiveness

The SHEAR BOLT ARM 700119303 delivers long-term economic value by combining superior durability, reliable performance, and OE-grade quality—addressing the core cost concerns of Massey Ferguson 1839/1840 operators: Reduced replacement costs: Its premium high-tensile alloy steel construction lasts 4–6 times longer than generic low-grade steel or iron arms, eliminating frequent part purchases and labor expenses for replacements; Avoided secondary damage: By ensuring controlled shear bolt failure and preventing arm deformation, it protects high-value baler assemblies (e.g., plunger mechanism, knotter system, and frame components) from costly repairs or premature breakdowns; Minimized downtime losses: During peak baling seasons, even a single hour of downtime can lead to significant crop spoilage and harvesting losses—its stable performance and fail-safe design avoid these disruptions and keep operations running smoothly. Compared to low-quality alternatives (which often bend, deform, or fail mid-season and accelerate wear of adjacent parts), this arm reduces the total operational and maintenance costs of the 1839/1840 balers across multiple farming cycles.
