ARM AGCO Part Number 700119299 AGCO Parts for Massey Ferguson 1839/1840 Small Balers

Product Advantage

The ARM, AGCO Part Number 700119299 is a vital structural linkage component custom-engineered for AGCO Massey Ferguson 1839/1840 Small Balers—high-productivity models trusted worldwide for efficient small-square baling of hay, forage, and straw in commercial farms, contracting operations, and rural estates. As a key load-transmitting element in the baler’s plunger and feed drive system, its core function is to connect the power take-off (PTO) linkage to the baler’s reciprocating plunger assembly, ensuring synchronized force transfer during the compression cycle. It stabilizes the dynamic movement of the plunger, maintains precise stroke alignment, and transmits consistent power to compact crop material into uniform bales: as the baler’s feed mechanism delivers crop to the compression chamber, the arm converts rotational PTO power into linear plunger motion, ensuring smooth coordination between the drive system, feed auger, and knotter unit. This robust linkage design directly prevents common operational issues such as plunger misalignment, inconsistent bale density, and drive system slippage—problems that lead to reduced baling efficiency, poor bale quality, and costly unplanned maintenance.

High Durability

Engineered to withstand the intense cyclic stresses of small-square baling—including continuous load fluctuations, exposure to crop debris, dust, moisture, and occasional impact from hard foreign objects—the ARM 700119299 is crafted from premium high-yield alloy steel (treated with a specialized heat process to enhance tensile strength, fatigue resistance, and impact toughness). It also features a dual-protection design to maximize service life in harsh agricultural operating environments:A heavy-duty anti-corrosion powder coating that shields the arm from rust, oxidation, and abrasive wear caused by crop residues and wet field conditions (common in early-morning baling or post-rain harvesting), preventing surface degradation and structural fatigue over prolonged use;A reinforced structural design with thickened load-bearing sections and precision-welded joints (where applicable), ensuring even load distribution and eliminating stress concentration at critical connection points. Even after supporting hundreds of thousands of plunger strokes across multiple farming seasons, the arm retains its original structural rigidity, dimensional stability, and load-transmitting capacity. This exceptional durability minimizes the need for frequent part replacements and significantly 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 ARM 700119299 ensures seamless integration with the baler’s existing drive and plunger systems. No modifications to the machine’s frame, adjacent components (e.g., PTO linkages, plunger brackets, or drive shafts), or mounting positions are required. Key design parameters are precision-matched to the original part: Connection hole diameter and spacing: Calibrated to fit the balers’ drive linkage pins and plunger mounting brackets without slack or interference, ensuring perfect alignment under full load conditions; Arm length and angular geometry: Matches the original arm’s specifications to maintain the precise plunger stroke length and motion trajectory, critical for consistent bale formation; Surface finish and mounting interface profile: Aligns with OE standards to ensure secure attachment and smooth rotational movement at connection joints, eliminating friction-induced wear. This “drop-in” compatibility enables fast, tool-friendly replacement—even in remote field locations—and preserves the baler’s original operational precision, eliminating malfunctions caused by ill-fitting aftermarket arms (e.g., plunger jamming, excessive vibration, or accelerated wear of drive system components).

Stable Performance

The ARM 700119299 delivers consistent, reliable performance even under extreme baling conditions—such as processing high-volume, dense crop stands (e.g., mature alfalfa, thick ryegrass) or operating at the balers’ maximum throughput rate. Its optimized design incorporates three critical performance features: High-yield alloy steel construction: Withstands the repetitive tensile and compressive forces generated by the baler’s drive system, preventing bending, warping, or fracture even under peak operational stress; Precision-machined connection interfaces: Ensures smooth, backlash-free movement between the arm and linked components, maintaining stable plunger stroke consistency and reducing mechanical vibration; Corrosion-resistant powder coating: Preserves structural integrity and performance in humid, dusty, or corrosive environments, avoiding performance degradation caused by rust buildup or debris accumulation at connection points. By maintaining precise plunger alignment, stabilizing power transmission, and resisting structural deformation, the arm sustains the baler’s operational efficiency—avoiding bale quality defects (e.g., under-compacted bales, irregular shapes) and production losses during critical harvesting windows.

High Precision

Produced using advanced precision forging and CNC machining (calibrated to AGCO’s strict OE tolerance standards of ±0.003 inches), the ARM 700119299 undergoes rigorous quality inspection at every manufacturing stage: Dimensional verification: Connection hole spacing, arm length, and angular geometry are measured via high-precision coordinate measuring machines (CMM) to ensure absolute compliance with OE specifications; Load capacity testing: Validates the arm’s ability to withstand rated static and dynamic loads without deformation or failure, ensuring adherence to AGCO’s performance requirements; Surface finish and alignment inspection: Uses laser alignment tools to verify the arm’s straightness and parallelism, guaranteeing smooth force transmission and minimal wear on mating components. This high precision achieves two key outcomes: Consistent mechanical synchronization: Ensures the baler’s drive system, plunger, and feed mechanism operate in perfect harmony, maintaining uniform bale density and optimal knotter performance; Extended service life of mating components: Reduces friction and wear on drive linkage pins, plunger brackets, and shafts, lowering the overall maintenance costs of the 1839/1840 balers.

Excellent Cost-Effectiveness

The ARM 700119299 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-yield alloy steel construction lasts 5–7 times longer than generic low-grade steel arms, eliminating frequent part purchases and labor expenses for replacements; Avoided secondary damage: By preventing plunger misalignment and structural failure, it protects high-value baler assemblies (e.g., drive system, plunger mechanism, and knotter unit) from costly repairs or premature breakdowns; Minimized downtime losses: During peak baling seasons, even a few hours of downtime can lead to significant crop losses due to weather exposure or missed harvesting windows—its stable performance avoids these disruptions and keeps operations running at full capacity. Compared to low-quality alternatives (which often bend or break mid-season and damage adjacent components), this arm reduces the total operational and maintenance costs of the 1839/1840 balers across multiple farming cycles.
