Product Specifications
The TC432-71540 lift arm acts as a left-hand linkage in Kubota’s three-point hitch, providing structural support for lifting. Grounded in Kubota’s specs for L series, this arm assures proper integration. The table outlines parameters for this arm and related Kubota lift arm variants, encompassing lengths, widths, hole sizes, materials, weights, and model fits, all based on Kubota’s authentic data for reliable farm implementation.

| Model Number | Length (mm) | Width (mm) | Mounting Hole Diameter (mm) | Material | Weight (Kg) | Finishing | Compatible Kubota Models |
|---|---|---|---|---|---|---|---|
| TC432-71540 | 400 | 70 | 20 | High-Strength Steel | 2.4 | Natural Color | L4600, L4701, L4708 |
| TC432-71530 | 410 | 72 | 21 | Forged Steel | 2.45 | Zinc Plated | L4600, L4701 |
| TA040-71540 | 390 | 68 | 19 | Alloy Steel | 2.35 | Natural | L4708, L4600 |
| TC432-71550 | 405 | 71 | 20.5 | High-Strength Steel | 2.42 | Powder Coated | L4701, L4708 |
| TA040-71550 | 395 | 69 | 19.5 | Forged Steel | 2.38 | Natural Color | L4600, L4701 |
These metrics highlight Kubota’s design for leverage, with lengths calibrated for balanced lifts in L4701’s 47 HP frame, handling up to 1,000 kg. Hole diameters ensure pin security, avoiding shear under stress. Materials like high-strength steel offer 850 MPa yield, critical for repeated cycles in seeding. Weights near 2.4 kg ease assembly while sustaining durability. Finishes protect in damp conditions, prolonging intervals between checks. Compatibility with L4600 (46 HP), L4701, L4708 supports tasks in compact utility tractors. Aligning to these prevents wobble, and torquing bolts at 45 Nm locks stability. This detail level lets technicians pinpoint mismatches, slashing idle time in planting seasons.

Applying this data refines part choices and service strategies.
Overview of the Lift Arm
This arm serves as a left-hand connector in Kubota’s hitch, bearing loads during raises. It links cylinders to implements, distributing force for steady elevation. In L4600 models, it aids in maintaining plow depth on uneven ground. Bolted at ends, it withstands pulls; damage from impacts causes drops. In Thai orchards, it stabilizes mowers against slopes. Integrated with 30 L/min pumps in L4708, it offers controlled motion. Broken arms result in uneven fields, harming yields; swaps restore evenness. Farmers tweak it for tool angle, optimizing pass efficiency. Its profile fits without mods, easing fits. Spotting bends early through lifts avoids breakdowns.

Knowing its mechanics supports quick issue resolution.
Strength Characteristics and Use Advantages
Made of high-strength steel, it tolerates 6,000 N forces sans warp. Reinforced holes spread tension, lasting through seasons. Natural coat fights rust in rain. Fits Category I hitches for tool variety. This fixes shake in loads, seen in L4701 hauling. 2.4 kg aids swift mounts. Matches hydraulics for fluid action. Coat pivots to halt binds. On-site, it lessens halts from snaps. Design skips alterations, speeding repairs.
Strength Highlights
- Steel force tolerance
- Hole reinforcement
- Rust fight
- Hitch fit
- Weight ease
These ensure steady field output.

Role in Kubota Systems
Vital for hitches, tying cylinders to tillers. Channels power in L4701’s setup for ground prep. Cushions hits, shielding pumps. Flexible in Thai lands, cutting special needs. Reviews find bends, permitting early swaps. Takes 1,000 kg, suiting compact units. Lowers power draw with balance. Core in service schemes, skip leads to chains of faults.

Bolsters machine dependability.
Spotting Damage and Care Approaches
Grind from dirt pits faces, leading misalignment. Damp rusts, thinning build. Over weights warp, usual in pulls. Shakes loose bolts, making slack. Dirt clogs fits. 50-hour looks catch twists. Tighten joins. Shield with coats. Change at breaks. Wash after to shed dirt.
Damage Signs
- Face pits
- Rust thin
- Warp
Care Methods
- Look tight
- Coat shield
- Change quick
Maintains working condition.
Swap Method Instructions
