How to Ship a Feller Buncher: Dimensions, Trailers & Permit Requirements

Feller Buncher Size and Weight Ranges

Feller bunchers vary significantly by manufacturer and model. Key transport specifications:

Size Class	Example Models	Operating Weight	Transport Width	Transport Length
Small	Cat 511, Tigercat 720G	24,000–35,000 lbs	8–9 ft	20–25 ft
Medium	Cat 521B, Tigercat 855E	35,000–65,000 lbs	9–11 ft	25–30 ft
Large	Cat 552, Weiler B357	65,000–80,000 lbs	10–12 ft	28–35 ft

The Caterpillar 521B, one of the most commonly shipped feller bunchers, weighs approximately 60,629 lbs with a transport length of 27'6", width of 10'6", and height of 12'4". The Weiler B357 weighs approximately 59,000 lbs with a transport length of 30 feet and width of 10'5". Both machines require oversize permits in virtually every state due to their width and weight.

Felling Head Removal Considerations

The felling head (saw head or disc saw) is the most significant variable in feller buncher transport. Options:

• Head attached: Possible for smaller machines where the head does not push the load over legal width or height limits. The head must be secured in the transport position (typically folded or lowered).
• Head removed: Required for most medium and large feller bunchers where the head would push the load over legal width or height limits. The head ships separately on a flatbed or alongside the machine on a multi-axle trailer. Head removal and reinstallation typically requires a qualified technician.
• Head tilted: Some feller buncher heads can be tilted to reduce transport width. Verify the tilted width before booking transport.

Trailer Selection for Feller Buncher Transport

Feller bunchers almost always require RGN lowboy trailers due to their height and weight:

• RGN Lowboy (standard): Suitable for small and medium feller bunchers up to approximately 60,000 lbs. The low deck height (18–24 inches) is essential for machines with heights of 11 to 13 feet.
• Multi-axle RGN: Required for large feller bunchers exceeding 60,000 lbs. Multi-axle configurations (3 to 5 axles) distribute weight to comply with bridge formula requirements. Also provides additional deck length for long machines.
• Extended RGN: For machines exceeding 30 feet in transport length, an extended RGN or jeep/booster combination may be required to provide adequate deck length.

Permit Requirements for Feller Buncher Shipping

Most feller bunchers require oversize and overweight permits in every state they travel through. Key considerations:

• Width permits: Required in all states for machines exceeding 8'6" wide. Most medium and large feller bunchers are 10 to 12 feet wide, requiring oversize permits and typically escort vehicles.
• Weight permits: Required for machines where the combined trailer and machine GVW exceeds 80,000 lbs. Most medium and large feller bunchers exceed this threshold.
• Escort vehicles: Required for loads over 12 feet wide in most states. Large feller bunchers may require both front and rear escorts.
• Travel restrictions: Many states restrict oversize loads to daylight hours only. Sunday travel is prohibited for oversize loads in some states (notably North Carolina). Holiday travel restrictions apply in most states.

Loading and Securement Requirements

Feller bunchers require careful loading and securement:

• The machine is driven onto the RGN trailer under its own power via the removable gooseneck ramp.
• The felling head must be secured in the transport position — either lowered to the deck or removed and secured separately.
• Primary tie-down chains attach to the machine's designated frame tie-down points — typically four to six points on medium and large machines.
• The boom and arm must be secured to prevent movement during transport.
• Track shoes must be blocked to prevent forward and rearward movement on the trailer deck.
