SM55SX 55 Inch Replacement Hay Tine – Cross-Hole Mount

The HAYSTIX® SM55SX 55 inch replacement hay tine is a spear-only service component for bale-handling frames that already have a usable straight cross-hole sleeve. It measures 55 inches long, has a 1.75 inch square profile, and is rated at 3,500 pounds at a 30 inch load center. Its extended reach can provide deep engagement when moving suitable large round bales, square bales, straw, silage, haylage, and other dense baled feed.

The SM prefix follows the same inclusion rule as an S model: no sleeve or collar is supplied. A cross-bolt, retaining nut, and mounting hardware are also not included. Buyers needing every mounting component should select the complete 55SX cross-bolt bale spear, which includes the matching 175 weld-in sleeve and fastening hardware.

Confirming the Existing Cross-Hole Mount

The SM55SX is straight and non-tapered. It does not seat in a Conus II collar and does not use the Doublenut® system. Instead, the spear slides into a straight sleeve until the cross holes in both parts align. A bolt passes through the aligned openings and is secured with the correct retaining nut.

Before ordering, compare the existing tine’s overall length, 1.75 inch square profile, straight mounting end, cross-hole location, sleeve depth, and bolt requirements. Sleeve inside diameter alone cannot confirm fit. The hole position must also match so the hardware can pass through without forcing or modifying either component. PRO-Link’s HAYSTIX® cross-bolt bale spear category can help buyers compare complete assemblies and spear-only replacements that use this mounting style.

Inspect the existing collar, its cross holes, surrounding frame, and welds before installing a new tine. Do not reuse a sleeve that is cracked, loose, distorted, heavily corroded, excessively worn, or unable to support the spear correctly. The 175 cross-hole sleeve is the matching PRO-Link option when the original mount must also be replaced.

To install the replacement, slide the shaft into the serviceable sleeve until the holes align naturally. Insert the specified cross-bolt through the collar and spear, then secure it with the retaining nut. Never force a bolt through misaligned openings, enlarge the holes, or substitute tapered mounting hardware.

55 Inch Replacement Hay Tine for Deep Bale Engagement

The long square tine can help a properly designed carrier maintain engagement while unloading trailers, stacking hay, carrying feed from storage, or positioning bales near livestock. Actual performance depends on spear spacing, frame angle, stabilizer-tine placement, bale condition, terrain, and operator technique.

Bale size does not reliably establish weight. Moisture, crop type, wrapping, and compression can make one bale substantially heavier than another of similar dimensions. Penn State Extension’s discussion of how much a hay bale really weighs provides useful background on why bale density and dry matter should be considered instead of judging the load by appearance alone.

When installed in a compatible carrier, the SM55SX may replace a hay spear in tractor front-end loader frames, skid steer attachments, three-point bale movers, telehandler carriers, wheel-loader frames, or custom agricultural equipment. These examples are not universal fit claims. The complete frame must provide the proper sleeve, tine position, spacing, structure, coupler geometry, operating clearance, ballast, and capacity for the machine and bale.

The published rating applies only to the individual spear. The sleeve, bolt, welds, frame, coupler, hydraulics, loader, and machine may create a lower working limit. Keep the bale low during travel and avoid sudden starts, stops, or turns. Inspect the point, shaft, cross hole, bolt, nut, sleeve, and frame regularly. The SM55SX is covered by PRO-Link’s one-year limited warranty against manufacturer’s defects, subject to the complete terms.

Questions & Answers

What is included with the SM55SX?

The SM55SX includes the 55 inch straight square replacement tine only. The sleeve, cross-bolt, retaining nut, and other mounting hardware are not included.

Will this 55 inch replacement hay tine fit every 1.75 inch sleeve?

No. The collar must accept the straight square mounting profile and have the correct depth, support, cross-hole position, and bolt clearance.

What should be inspected before replacing the tine?

Check the existing sleeve, holes, welds, surrounding frame, and fastening hardware. Replacing the spear alone is not appropriate when another structural or mounting component is damaged.
