SM43TXJ 43-Inch Replacement Hay Spear – Tapered

The HAYSTIX® SM43TXJ 43-inch replacement hay spear is a spear-only service part for restoring a compatible bale-handling attachment without buying another sleeve. Its 1.75-inch square profile, Conus II tapered mount, and Doublenut® retention system match PRO-Link’s heavy-duty HAYSTIX® configuration. Rated at 3,500 pounds at a 30-inch load center, this tine provides deep engagement for large round bales, square bales, silage, straw, and other dense feed materials.

Because the model begins with “S,” no sleeve or collar is included. The SM43TXJ is intended for an existing, serviceable 144T weld-in sleeve or for a properly designed system using that compatible collar. It is a practical choice when the original bale spike is bent, worn, cracked, or missing but the installed sleeve and attachment frame remain in usable condition.

Replace a Damaged Tine Without Rebuilding the Frame

Changing only a damaged hay tine can return an otherwise sound attachment to work while avoiding the cutting and welding required to remove an undamaged collar. Before ordering, compare the old component’s 43-inch length, 1.75-inch square profile, Conus II taper, threaded end, and Doublenut® mounting method. The complete 43TXJ assembly includes the 144T weld-in sleeve; the SM43TXJ supplies the corresponding bare spear and retaining nuts for buyers who already have the correct mount.

This model is also the verified spear used in the AG-GO U7264-436 square hay bale frame, which carries seven 43-inch tines. Owners servicing that attachment should inspect the collar, frame, welds, and neighboring spears before changing one part. A matching model number helps identify the component, but the condition of the complete carrier determines whether a tine-only repair is appropriate.

The 43-inch reach allows the point to engage deeply into suitable bales during feeding, stacking, staging, and trailer loading. Its gradual taper helps separate compacted fibers during entry and reduces the amount of shaft surface held by the bale during withdrawal. Operators should engage a stable portion of the bale, keep the load low during travel, and avoid sudden turns or stops on uneven ground.

Bale weight changes considerably with size, density, moisture, and material. The published 3,500-pound rating applies to the individual spear at the stated load center. It does not establish the capacity of the finished frame, coupler, loader, attachment, welds, or machine. Always follow the lowest-rated component in the complete system.

144T Sleeve Compatibility and Doublenut® Installation

The tapered shank seats inside the existing 144T sleeve. Tightening the first nut draws the taper firmly into the collar, while the second nut locks against it to help resist loosening from vibration and repeated handling. The square shank should be oriented as required by the attachment design before final tightening. Inspect the tapered surfaces, threads, sleeve, and hardware before assembly, and confirm that both nuts are properly secured before use.

When installed in a compatible bale attachment, the SM43TXJ may serve tractor front-end loaders, skid steers, telehandlers, and custom hay carriers. These machine categories do not mean the tine fits every attachment used on those machines. Compatibility depends on the installed 144T sleeve, frame layout, coupler, clearances, weld quality, spear spacing, and capacity of the finished equipment.

Check the hay stab before each work period and stop using it if it is loose, bent, cracked, severely worn, or damaged at the threads or taper. If the sleeve is distorted, cracked, loose in the frame, or no longer holds the spear correctly, replace the appropriate components and have the attachment evaluated by a qualified fabricator. PRO-Link covers the SM43TXJ with a one-year limited warranty against manufacturer’s defects, subject to the complete warranty terms.

Questions & Answers

Does the SM43TXJ include a 144T sleeve?

No. It is a spear-only model for an existing compatible sleeve. Choose the complete 43TXJ assembly when the repair also requires a new 144T weld-in collar.

What should I compare before ordering this 43-inch replacement hay spear?

Confirm the original tine’s model, length, diameter, Conus II taper, threaded Doublenut® connection, and 144T sleeve. Inspect the frame and collar to ensure a spear-only repair is suitable.

Can the SM43TXJ replace a tine on an AG-GO U7264-436 frame?

Yes. PRO-Link identifies the SM43TXJ as the spear used on that seven-tine square-bale frame. Verify the attachment model and inspect the installed sleeve and structure before installation.
