How to Ship a Log Skidder: Complete Transport Guide
Log skidders are specialized forestry machines used to drag felled timber from the cutting area to a landing zone for processing. Industrial skidders range from 18,000 to 38,000 lbs and span 17–24 feet in length, with widths that frequently exceed the 8.5-foot legal limit — making oversize permits a standard requirement for most skidder moves. IronHaul Logistics has experience transporting forestry equipment from remote logging sites, auction yards, and dealer lots across the United States.
Log Skidder Dimensions and Weight Ranges
Industrial log skidders vary significantly by model and manufacturer. The following table shows representative specifications for common skidder classes:
| Size Class | Length | Width | Height | Weight |
|---|---|---|---|---|
| Small (e.g., Franklin 4000) | ~17 ft | ~8 ft 6 in | ~10 ft 2 in | ~18,000 lbs |
| Medium (e.g., Franklin 170S2) | ~21 ft | ~8 ft 3 in | ~10 ft | ~20,000 lbs |
| Large (e.g., Franklin 170M31) | ~22 ft | ~9 ft 6 in | ~9 ft 10 in | ~26,250 lbs |
| Heavy (e.g., Franklin 660M66) | ~23 ft 6 in | ~10 ft 2 in | ~10 ft 1 in | ~30,200 lbs |
| Extra Heavy (e.g., Franklin Q90) | ~23 ft 6 in | ~9 ft 11 in | ~10 ft 11 in | ~38,000 lbs |
Always verify your specific machine's dimensions with the manufacturer spec sheet before booking transport. Weights listed above are typically operating weight without attachments or fluids drained.
Federal Permit Thresholds
Most industrial log skidders will trigger oversize permit requirements:
- Width: Legal limit is 8.5 ft. Most medium and large skidders exceed this, requiring overwidth permits.
- Height: Legal limit is 13.5 ft. Skidders are typically 10–11 ft tall, which is within legal height limits on most routes.
- Weight: Federal GVW limit is 80,000 lbs. Most skidders are well under this limit, but the combined weight of tractor + trailer + machine must be calculated.
Trailer Selection for Log Skidders
The right trailer depends on your skidder's dimensions and weight:
- Flatbed (48'–53'): Suitable for smaller skidders under 8.5 ft wide and under 48,500 lbs. The machine must be able to drive or be winched onto the flatbed.
- Step Deck / Drop Deck: Provides additional height clearance for taller skidders. Good option for machines 8.5–11 ft tall that are within weight limits.
- Lowboy / RGN: Best option for larger, heavier skidders. The low deck height (18–24 inches) keeps the total load height within legal limits. RGN trailers allow the skidder to be driven on under its own power if the machine is operational.
Loading Considerations
Log skidders present unique loading challenges that differ from standard construction equipment:
- Remote pickup locations: Skidders are often located at active logging sites with soft ground, steep grades, and limited turnaround space. Inform your carrier about site conditions so they can bring appropriate equipment (winch truck, ramps).
- Grapple and blade attachments: Many skidders have grapple arms or blades that extend the overall length and width. These must be folded or removed for transport. Confirm with your carrier whether attachments can remain on the machine.
- Tire condition: Large skidder tires can be damaged during loading if the ramp angle is too steep. RGN trailers with low ramp angles are preferred for machines with large tires.
- Fluid management: Some states require hydraulic fluid to be drained or secured before transport. Check with your carrier about state-specific requirements.
Tie-Down Requirements
Per FMCSA regulations, log skidders must be secured with chains rated to at least 50% of the machine's weight per tie-down point. Minimum requirements:
- At least 4 tie-down chains for machines over 10,000 lbs
- Chains must be attached to designated tie-down points on the machine frame (not to hydraulic lines, cylinders, or attachments)
- Binders must be properly tensioned and checked at each stop
- Wheel chocks required for wheeled skidders
Cost Factors for Skidder Transport
- Distance: Per-mile rates decrease on longer hauls. Short hauls (under 100 miles) typically run $3–$5/mile; long hauls (500+ miles) typically run $1.75–$3/mile.
- Oversize permits: Wide skidders require overwidth permits in each state on the route, adding $200–$600 in permit fees.
- Escort vehicles: Required for loads over 14 ft wide in most states — $150–$300 per escort per day.
- Remote site access: Difficult pickup locations (soft ground, steep grades, limited access) may require a winch truck or additional equipment, adding to the base rate.

Common questions
What trailer do I need to ship a log skidder?
Most industrial skidders require a step deck or lowboy/RGN trailer. Smaller skidders under 8.5 ft wide and 48,500 lbs can use a flatbed. Larger skidders with widths over 8.5 ft need oversize permits and typically a lowboy or RGN for safe loading.
Can a log skidder be driven onto the trailer?
If the skidder is operational and the trailer has a ramp (RGN or step deck with ramps), the machine can often be driven on. Non-operational skidders require winching. Inform your carrier of the machine's operational status when requesting a quote.
How do I ship a skidder from a remote logging site?
Remote site pickups require advance planning. Provide your carrier with GPS coordinates, site access road conditions (width, grade, surface), and any obstacles. IronHaul can dispatch a winch truck if needed and will assess site conditions before sending a trailer.
Do I need oversize permits to ship a log skidder?
Most industrial skidders exceed the 8.5 ft legal width limit and require overwidth permits. IronHaul handles all permit applications as part of the move — just provide your machine's dimensions and we'll manage the paperwork.
How much does it cost to ship a log skidder?
Cost depends on distance, machine dimensions, and site access. Short hauls (under 100 miles) typically run $800–$2,500. Long-distance moves (500+ miles) typically run $3,000–$8,000 depending on oversize requirements and escort needs. Contact IronHaul for an accurate quote based on your specific machine and route.
