3A011-82960 Hydraulic Lift Arm Fits For Kubota Tractor

Product Specifications

The 3A011-82960 hydraulic lift arm functions as an upper linkage in Kubota’s three-point hitch system, supporting load lifting in tractors. Derived from Kubota’s engineering details for M series models, this component offers robust compatibility. The table below lists parameters for this arm and related Kubota variants, including dimensions, materials, weight, and fitment, all aligned with Kubota’s original standards for dependable use in farming operations.

These specifications demonstrate Kubota’s emphasis on structural integrity, with lengths tailored for optimal leverage in hitch systems, supporting lifts up to 1,500 kg in M7040 models. Mounting holes are drilled to precise diameters for secure bolting, preventing slippage under torque. Materials like high-tensile steel achieve strengths over 900 MPa, essential for enduring cyclic loads in tilling or hauling. Weight distribution at around 5 kg aids in balanced operation without adding undue strain to hydraulics. Finishing protects against oxidation in tropical humidity, extending service intervals. Compatibility across M5000 (50 HP), M6040 (62 HP), and M7040 (71 HP) allows versatile application in diverse farm tasks. Selecting based on these details avoids fit issues, and adhering to Kubota’s 50-60 Nm bolt torque specs optimizes safety. This precision enables mechanics to address lift failures swiftly, reducing field downtime in busy seasons.

Such parameters guide effective diagnostics and upgrades for sustained performance.

Understanding the Hydraulic Lift Arm

This arm forms the upper link in Kubota’s three-point hitch, enabling hydraulic control for raising and lowering implements. It transfers cylinder force to attachments, maintaining level positioning during operations. In M6040 tractors, it handles adjustments for plows in uneven soil, ensuring consistent depth. Without it, hitches could sag, leading to inefficient work or damage. Installation bolts to the tractor frame, with adjustments via turnbuckles for alignment. Exposure to loads causes bending if overloaded, so monitoring for deformation is key. Its role in stabilizing heavy equipment like balers prevents tipping in sloped fields common in Thailand. By facilitating quick height changes, it boosts task versatility, from mowing to loading. Technicians can test functionality by cycling the hitch, checking for smooth motion and leaks. This component’s design integrates with Kubota’s hydraulic pumps, rated at 35 L/min in M5000, for responsive control. Addressing wear early avoids costly repairs to cylinders or valves.

Grasping its mechanics aids in preventing operational disruptions.

Durability Features and Performance Enhancements

Built from high-tensile steel, the arm resists deformation under 1,000 kg forces. Reinforced mounting points distribute stress, extending life in repetitive lifts. Natural finishing shields from corrosion in rainy climates, reducing pitting. Adjustable lengths via threads allow fine-tuning for implement balance. This tackles instability issues in heavy-duty use, like hauling in M7040’s 71 HP setup. Weight of 5.16 kg optimizes hydraulics without overload. Compatibility with Category II hitches ensures broad tool use. Maintenance involves greasing pivots to cut friction, preventing seizures. In practice, it cuts downtime by withstanding impacts from rough terrain. Mechanics value the straightforward bolt-on design, fitting without modifications.

These traits deliver consistent output in rigorous farming.

Advantages in Agricultural Tasks

Boosts lift capacity for M5000, handling 1,200 kg implements efficiently. Provides stable positioning, reducing crop damage in precise planting. Quick adjustments speed up switching tools, enhancing workflow in mixed farms. In hilly Thai regions, it maintains level hitches, preventing slips. Operators note reduced fatigue from smooth hydraulics. Safety improves with secure attachments, avoiding detachments. Economically, longer intervals between repairs cut costs. Integrates with Kubota’s controls for intuitive use.

Reliable lifts enable solo handling of heavy loads.

Resolves efficiency hurdles in daily work.

Significance in Kubota Equipment

Critical for three-point systems, linking hydraulics to tools like harrows. Ensures torque transfer in M6040’s 62 HP engine for soil prep. Protects pumps from overload by absorbing shocks. Versatile in Thai varied terrains, minimizing specialty needs. Inspections spot bends, allowing preemptive fixes. Handles 1,500 kg distributions, suiting mid-size tractors. Lowers fuel use through efficient mechanics. Vital in integrated maintenance, where neglect cascades problems.

Underpins reliable machine function.

Wear Issues and Maintenance Strategies

Soil abrasion wears surfaces, causing misalignment. Moisture corrodes finishes, weakening structure. Overloads bend arms, common in towing. Loose bolts from vibration lead to play. Seals fail, allowing leaks. 50-hour inspections check deformations. Torque bolts regularly. Apply anti-corrosive coatings. Replace at signs of cracking. Clean after use to remove debris.

Keeps equipment operational.

Step-by-Step Replacement Process

Secure tractor, lower hitch, disconnect power. Remove pins and bolts from old arm. Clean mounting areas. Align new arm, insert bolts, torque to 55 Nm. Adjust length for level. Cycle hitch to test. Tools: wrenches, torque tool. Monitor for leaks post-install.
