Complete Tractor 3013-1639 Universal Leveling Arm
This leveling arm provides an adjustable CAT I connection with a ball end and a 0.765″ pin hole. Body length is 11.5″, with an adjustable range from 16.5″ to 27.5″. It’s designed as a replacement for 1590115 and ships with a 1-year warranty. The build emphasizes durability and ease of install, making it suitable for tractors needing a reliable leveling arm component without major reengineering.
Key considerations include compatibility with existing hitch hardware and the ease of installation in the field. The included warranty offers protection against defects while allowing straightforward replacements if issues arise. This option is particularly suitable for operators seeking a straightforward CAT I upgrade or replacement that aligns with common implement kits.
Complete Tractor 3013-1632 Lift Arm
This red CAT I lower lift arm features a 32″ CTC length with a 7/8″ inside diameter. It’s listed as compatible with a range of classic tractors (including historical models) and carries a one-year warranty. The design emphasizes compatibility with widely used implement shapes, supporting robust lift performance during planting and harvesting cycles. The product aims to provide a simpler path to a reliable lift arm replacement for legacy tractors.
Consider whether your loader or tillage implements require the 32″ center-to-center length and a specific pin diameter. If your system relies on a standard CAT I hitch with compatible receivers, this arm offers a balanced option between compatibility and performance.
RAParts LA3325 Universal Lift Arm Repair End
RAParts LA3325 is a new universal, straight lift arm repair end made of forged steel with Category II hole compatibility. It features a 1-1/8″ pin hole and a 2-¾” width at the weld end. The design focuses on a straightforward replacement end cap for worn-out lift arms, enabling improved hitch stability and smoother 3-point operations. The component is intended for operators who need a durable end piece to reestablish hitch geometry without replacing the entire arm.
When evaluating this option, assess if your existing arm’s weld end width and hole alignment match the described dimensions. This can be a practical choice when upgrading or repairing an older system with minimal downtime.
Complete Tractor 3013-1620 Universal Stabilizer Arm
The stabilizer arm option features a length of 31 9/16″ and an inside diameter of 7/8″, designed to work as part of a 3-point hitch stabilization setup. It’s presented as compatible with multiple replacement parts including 181778M1 and 230042R, and comes with a one-year warranty. The stabilizer arm focuses on reducing side-to-side sway during heavy implement load, contributing to safer and more predictable lift performance during field operations.
Key considerations include the overall hitch geometry, alignment with existing stabilizer links, and whether your implement setup benefits from added stabilizer stiffness. This arm can be especially useful on wider, heavier implements or when using implements with higher side loads.
Complete Tractor 1113-3002 Hydraulic Lift Arm
This hydraulic lift arm is designed for Ford/New Holland platforms and is compatible with several 3-cylinder engines in the 65-74 range. Features include a C-C length of 34.65″, a width of 3.5″, and a thickness of 709. It replaces OEM numbers such as 81821330, and is compatible with a wide set of models including 250C, 260C, 2810, 2910, and several 3000 series variations. The hydraulic lift arm integrates with hydraulic circuits to support lifting power for larger implements and heavy-duty tasks.
When choosing this arm, verify that the hydraulic system and cylinder bore match your tractor’s specifications. Compatibility with a broad set of Ford/New Holland models makes this a versatile option for mixed-use fleets or older tractors undergoing hydraulic upgrades.
Buying Guide: Key Purchase Considerations
- Compatibility: Confirm hitch category (CAT I vs II), hole spacing, pin diameter, and center-to-center length against your tractor and implements. Mismatches can cause improper hitch alignment or unsafe operation.
- Material and construction: Forged or solid steel arms tend to endure higher loads and wear. Check for corrosion protection and coating suitable for farm environments.
- End fittings and pins: Ensure pin hole diameters and weld-end widths match your current hardware to prevent loosening or misalignment during use.
- Warranty and support: A one-year warranty or longer can protect against manufacturing defects. Look for suppliers with straightforward replacement policies in case of compatibility issues.
- Hydraulic compatibility: If choosing a hydraulic lift arm, verify hydraulic line connections, cylinder compatibility, and load capacities to avoid overloading the hitch system.
- Warranty and service availability: Consider brands that offer clear customer service paths and accessible replacement parts to minimize downtime.
- Intended use: For heavy implements or frequent field work, prioritize stiff stabilizers and arms with robust end caps to minimize play and wear.
- Installation effort: Some arms require simple bolt-on installation; others may demand alignment adjustments. Plan for basic tools and potential helper assistance.
These options provide a range of choices from simple replacement ends to full hydraulic lift arms. When evaluating, prioritize fit with your specific tractor model, the type of implements you use, and how often you perform heavy-duty lifting tasks. A properly matched third arm improves lift stability, reduces wear on the hitch system, and contributes to safer operation in daily farm use.
