How to Ship a Stump Grinder or Forestry Mulcher: Trailer Types and Costs

Equipment Categories and Size Ranges

Stump grinders and forestry mulchers fall into several distinct categories, each with different transport requirements:

Permit Requirements

Permit requirements depend on the machine's transport dimensions:

• Small tow-behind and walk-behind grinders: Typically within legal dimensions — no oversize permits required. These machines are compact enough to ship on a standard flatbed without permits.
• Self-propelled ride-on grinders (8,000–20,000 lbs): Usually within legal width (under 8 ft 6 in) but may approach height limits. Verify transport height before booking.
• Commercial track grinders (20,000–40,000 lbs): May exceed 8 ft 6 in in width due to wide cutting heads. Oversize width permits and pilot cars may be required.
• Self-propelled forestry mulchers (30,000–60,000 lbs): Frequently exceed legal width and height limits. Oversize permits, pilot cars, and route surveys are commonly required. Some machines may qualify as superloads (over 150,000 lbs GVW with trailer).

Trailer Selection

The right trailer depends on the machine's weight, width, and height:

• Flatbed (48 ft): Best for tow-behind grinders, walk-behind grinders, and small self-propelled units under 8 ft 6 in wide and 13 ft 6 in tall. Multiple small units can often be loaded on a single flatbed.
• Step-Deck (48–53 ft): Preferred for mid-size self-propelled grinders (8,000–20,000 lbs) that may approach height limits on a flatbed. The lower deck height provides additional clearance.
• Lowboy / RGN: Required for commercial track grinders (20,000–40,000 lbs) and self-propelled forestry mulchers (30,000–60,000 lbs). RGN trailers allow ground-level loading for machines that cannot climb steep ramps.

Special Considerations for Forestry Equipment

Forestry equipment presents unique transport challenges:

• Cutting head width: Forestry mulchers often have wide cutting heads that extend beyond the machine's main frame. Measure the cutting head width carefully — this is frequently the widest point of the machine and the dimension that triggers oversize permit requirements.
• Soil contamination: Many states require that forestry equipment be cleaned of soil and plant material before transport to prevent the spread of invasive species. Some states have specific inspection requirements for equipment moving from areas with known invasive species.
• Hydraulic components: Secure all hydraulic cylinders and hoses before transport. Forestry mulchers have complex hydraulic systems that can be damaged if components shift during transit.
• Carbide teeth: Forestry mulcher cutting teeth are extremely sharp. Ensure the cutting head is properly guarded or covered during transport to prevent damage to the trailer and injury to handlers.

Cost Factors

Stump grinder and forestry mulcher shipping costs depend on several variables:

• Machine size: Small tow-behind grinders cost $300–$800 for regional moves. Large commercial track grinders and forestry mulchers cost $2,000–$8,000+ depending on distance and permit requirements.
• Distance: Short hauls (under 200 miles) are significantly less expensive than cross-country moves.
• Permit requirements: Oversize permits for wide cutting heads add $100–$400 per state. Pilot cars add $300–$800 per car.
• Cleaning requirements: If the machine requires cleaning before transport (soil contamination), budget $100–$300 for professional cleaning.
