Sprocket 700124886 Sprocket 18 Tooth AGCO Parts for Massey Ferguson 1839 1840 Square Baler

Product Advantage

The Sprocket 700124886, 18 Tooth is a core power transmission component exclusively engineered for the drive system of AGCO Massey Ferguson 1839/1840 Square Balers—a key model series widely used in small and medium-scale hay, forage, straw and crop stalk baling operations. Its primary role is to precisely transmit and regulate rotational power in the baler’s drive chain during the baling cycle: as the baler executes material conveying, compression, cutting and knotting actions, the 18-tooth sprocket meshes with the drive chain to deliver stable, synchronized power to critical working components (e.g., feed rollers, cutting assembly, knotter system). This critical power coordination directly prevents chain slippage, inconsistent component speed, or interrupted power transmission—common issues that cause costly field work halts, compromised baling efficiency and defective bale forming.

High Durability

Crafted to withstand the harsh operating conditions of square baling (continuous meshing friction, dynamic load impact, and exposure to dust/moisture and crop residues), the Sprocket 700124886, 18 Tooth is manufactured from high-quality carbon structural steel (heat-treated for enhanced surface hardness and core toughness). It undergoes a specialized surface treatment process (anti-rust phosphating + high-strength wear-resistant quenching) that forms a protective barrier against: Premature tooth wear and deformation from continuous meshing friction with the drive chain during high-speed baling cycles; Corrosion and oxidation caused by field dust, moisture and crop juice residues (common in damp baling environments); Impact and fatigue damage from sudden load changes and chain shock during start-stop and heavy-load baling operations.Even after a full farming season of intensive baling operations, the sprocket maintains its original tooth profile precision, structural rigidity and meshing stability—reducing the need for frequent replacements and minimizing unplanned downtime for the Massey Ferguson 1839/1840.

High Compatibility

Meticulously engineered to meet AGCO’s original equipment (OE) specifications for the Massey Ferguson 1839/1840 Square Baler, the Sprocket 700124886, 18 Tooth ensures seamless integration with the baler’s existing drive chain assembly—no modifications to the machine’s drive frame, adjacent transmission components (e.g., chain guides, tensioners), or mounting structure are required. Key design details are precision-matched to the original part: 18-tooth profile, pitch and outer diameter (ensures perfect meshing with the baler’s original drive chain); Bore size, keyway dimensions and mounting hole position (aligns exactly with the baler’s drive shaft and fixing structure); Hub thickness and outer contour (compatible with the OE chain guard and transmission housing of the 1839/1840).This “drop-in” compatibility enables quick, tool-friendly replacement (even in field settings) and preserves the baler’s original drive transmission accuracy—avoiding malfunctions caused by ill-fitting aftermarket sprockets (e.g., chain jump, abnormal noise, component speed mismatch).

Stable Performance

The Sprocket 700124886, 18 Tooth delivers consistent performance even under the most demanding baling scenarios—including processing dense, heavy crop material (e.g., wet hay, thick corn stover) or operating at the 1839/1840’s maximum baling speed. Its optimized design features: Precision-machined tooth profile (uniform tooth spacing and smooth surface reduce chain meshing resistance, preventing slippage under heavy load); Balanced structural design (minimizes rotational vibration and runout, ensuring stable power transmission at high speed); Reinforced hub and rim connection (resists cracking and deformation under dynamic load impact during continuous operation).By eliminating chain slippage, abnormal meshing or power transmission instability, the sprocket sustains the baler’s operational efficiency—avoiding bale quality defects (e.g., uneven compression, incomplete knotting) and production losses during peak harvesting seasons.

High Precision

Produced using advanced CNC hobbing and precision machining technology (specifically calibrated for AGCO’s OE tolerances), the Sprocket 700124886, 18 Tooth undergoes rigorous quality inspection at every manufacturing stage: Dimensional verification (tooth pitch, bore size and mounting position checked to ±0.03mm accuracy); Tooth profile and surface testing (ensures smooth meshing with the drive chain and eliminates friction hotspots); Hardness and concentricity validation (measured via professional testing equipment to meet AGCO’s OE performance standards).This high precision ensures two critical outcomes: Synchronized power transmission (guarantees consistent speed of all working components, critical for stable and efficient baling operation); Perfect alignment with the 1839/1840’s drive system timing (avoids chain wear acceleration and transmission component damage caused by misalignment).

Excellent Cost-Effectiveness

The Sprocket 700124886, 18 Tooth delivers long-term economic value by combining durability, reliability, and OE-grade performance—addressing the key cost drivers for Massey Ferguson 1839/1840 operators: Reduced replacement costs: Its heat-treated steel design and precision tooth profile last 3–5x longer than generic aftermarket sprockets, eliminating frequent part purchases; Avoided secondary damage: By preventing chain slippage and meshing failure, it protects high-value drive components (e.g., drive chain, tensioners, gearbox) from costly wear and repairs; Minimized downtime losses: During peak baling seasons, even short downtime can lead to significant lost crop harvesting—its stable performance avoids these losses.Compared to low-quality alternatives (which often suffer tooth wear or deformation mid-season), this sprocket lowers the 1839/1840’s total operational and maintenance costs over multiple farming cycles.

Large Inventory & Fast Delivery

We maintain a dedicated, large-scale inventory of the Sprocket 700124886, 18 Tooth—specifically stocked to meet urgent replacement needs during peak baling seasons (spring hay, summer and fall crop stalk baling). Our logistics network is optimized for agricultural customers, offering: Fast delivery to farms, agricultural service centers, or repair workshops (2–3 day turnaround for most regions); Priority shipping options for emergency cases (e.g., mid-harvest sprocket tooth wear or chain jump failure); Complimentary technical support: Our AGCO-certified team provides pre-purchase compatibility checks (to confirm fit with specific 1839/1840 serial numbers), on-site installation guidance, and post-installation maintenance tips (e.g., chain lubrication schedules, sprocket wear inspection recommendations).This end-to-end support ensures customers get the right part quickly, minimizing operational interruptions and keeping their Massey Ferguson 1839/1840 balers running at full capacity.
