HAYSTIX® SM49FX Bolt On Bale Stab – 49″ x 1.75″ – 3,500 lb. Capacity

The HAYSTIX® SM49FX bolt on bale stab is a heavy-duty replacement bale spear designed for operators who already have a compatible sleeve system and need dependable performance for demanding hay handling applications. Built for tractors, skid steers, telehandlers, bale movers, and commercial agricultural equipment, the SM49FX delivers strong bale penetration, stable load support, and long-term durability during repeated lifting cycles.

Featuring a rugged 1.75-inch square spear profile and a 49-inch overall length, the SM49FX is engineered to handle large round bales, dense square bales, silage, haylage, and other heavy feed materials where strength and stability are essential.

The SM49FX is a replacement spear only and does not include a sleeve collar or mounting hardware, making it ideal for replacing worn bale spears while reusing existing compatible mounting systems.

Rated at 3,500 pounds at a 30-inch load center, the SM49FX is built for high-demand agricultural operations requiring dependable bale handling performance.

Cross Bolt-On Bale Spear Design

The SM49FX uses a cross bolt-on mounting system designed to provide secure spear retention while allowing easier replacement compared to permanently welded spear assemblies.

This mounting system helps provide:

• Secure spear retention
• Simplified spear replacement
• Reduced downtime during repairs
• Easier long-term serviceability
• Reliable heavy-load performance

The cross-hole design allows operators to replace damaged or worn bale spears without rebuilding or cutting apart the attachment frame.

The 49-inch spear length also helps improve:

• Bale penetration depth
• Load balance during transport
• Bale stability on rough terrain
• Stacking control
• Reduced bale shifting during movement

This design performs especially well when handling:

• Large round hay bales
• Dense square bales
• Wet hay
• Silage
• Haylage
• Cornstalk bales
• High-compression feed material

Four-Sided Fluted Design & Agricultural Durability

The SM49FX features a reinforced four-sided fluted spear profile engineered to improve structural rigidity while reducing resistance during penetration and removal.

Its fluted design helps:

• Improve penetration into dense hay
• Reduce drag during withdrawal
• Improve load support under heavy conditions
• Reduce stress on the spear and attachment
• Improve long-term durability

The square fluted profile also supports multi-directional mounting flexibility. As long as the cross-bolt holes align properly, the spear can be mounted in different orientations without modifying the attachment.

Manufactured from heat-treated high-strength steel, the SM49FX is engineered to resist:

• Bending under load
• Fatigue from repeated lifting cycles
• Excessive flexing
• Premature wear
• Structural deformation

The SM49FX is commonly used on:

• Tractor loader bale spear frames
• Skid steer hay spear attachments
• Telehandlers
• Bale movers
• AG-GO hay handling equipment
• Commercial feeding systems
• Custom fabricated agricultural attachments

Its combination of heavy-duty construction, bolt-on flexibility, and reinforced fluted design makes the SM49FX an excellent replacement spear for high-use agricultural operations.
