How to Ship a Combine Harvester: Complete Transport Guide

Combine Harvester Size and Weight Ranges

Modern combines span a wide range of sizes. The header is almost always removed for transport and shipped separately, so dimensions below reflect the combine body only:

Header Removal: Always Required for Transport

The combine header (the wide cutting attachment at the front) is almost always removed before transport. Headers can be 20–45 ft wide — far exceeding any legal transport width. The header is shipped separately, typically on a flatbed or step deck trailer, and may require its own oversize permit if it exceeds 8.5 ft in width when folded or disassembled.

Header removal is typically performed by the operator or a dealer technician before the carrier arrives. The header is placed on a header trailer or transport cart for separate shipment. Confirm header removal logistics with your carrier when booking — some carriers can arrange header transport as a second load.

Trailer Selection for Combine Transport

Even without the header, most combines require specialized trailers due to their height and weight:

• Step Deck: Suitable for smaller combines (under 35,000 lbs) that can be transported within height limits on a lower deck. The step deck's lower rear section (typically 34–36 inches off the ground) provides additional height clearance compared to a standard flatbed.
• Lowboy / RGN: The preferred trailer for most large combines. The lowboy's deck height of 18–24 inches provides maximum height clearance, which is critical for combines that stand 13–15 ft tall. The RGN's removable gooseneck allows the combine to drive directly onto the deck.
• Double-Drop / Lowboy with Outriggers: For extra-large combines that are both tall and wide, specialized configurations with outrigger axles may be required to distribute weight and maintain legal axle loads.

Oversize Permit Requirements

Combines almost universally require oversize permits because they exceed standard width (8.5 ft) and often height (13.5 ft) limits even with the header removed. Key permit considerations:

• Width permits: Required in every state for combines over 8.5 ft wide. Most large combines are 12–16 ft wide at the body, requiring one or two pilot cars depending on state rules.
• Height permits: Required for combines over 13.5 ft tall. Many large combines are 13–15 ft tall, requiring height permits and route surveys for bridge clearances.
• Daylight travel restrictions: Most states restrict oversize load movement to daylight hours. This is particularly important for harvest-season moves when scheduling is time-sensitive.
• Holiday and weekend restrictions: Many states prohibit oversize load movement on major holidays and some weekends. Plan accordingly during peak harvest season (September–November).

Preparing a Combine for Transport

• Remove the header: Always remove and arrange separate transport for the header before the carrier arrives.
• Fold or remove the unloading auger: The grain unloading auger extends significantly beyond the combine body. Fold it to the transport position or remove it if it cannot be folded within legal dimensions.
• Measure in transport configuration: Take final height, width, and length measurements with the header removed and auger folded. These measurements are required for accurate permit applications.
• Drain excess grain: Ensure the grain tank is empty before transport. Grain adds significant weight and can shift during transit.
• Disconnect the battery: Disconnect the battery to prevent electrical shorts during transport.
• Secure cab accessories: Remove or secure loose items in the cab, including GPS monitors, mirrors, and any accessories that could shift or fall during transport.

Seasonal Timing Considerations

Combine transport demand surges during and after harvest season (September–November in most of the US). During this period, carrier availability tightens and scheduling lead times increase. Key timing considerations:

• Pre-harvest moves: Moving a combine before harvest season (July–August) typically offers better carrier availability and pricing.
• Post-harvest moves: After harvest (November–December), combines often move from farm to dealer or auction. This is a peak period for agricultural equipment transport.
• Auction moves: Combines purchased at fall auctions (Ritchie Bros, Purple Wave, IronPlanet) need to be moved quickly. Book transport as soon as the auction closes to secure carrier availability.
