Why Agriculture Relies on Heavy Haul
American agriculture has always moved equipment. Custom harvest crews follow the wheat and corn harvest northward each summer. Farmers purchase equipment from distant dealers. Co-ops relocate combines and grain handling systems between facilities. Ag dealerships deliver large tractors and planters to buyers across the country. In every case, the equipment is too large, too wide, or too heavy to haul in a standard truck — it requires an oversize load permit, a specialized trailer, and a carrier who understands the specific loading and dimension requirements for agricultural equipment.
R&RM LLC has been providing farm equipment hauling since 2011, serving farms, co-ops, dealers, and custom harvest operations in the Southeast, Midwest, and Plains states. This guide explains how agricultural heavy haul works — what permits are required, which trailers are used, what seasonal factors affect moves, and how to plan a farm equipment shipment efficiently.
What Agricultural Equipment Qualifies as Heavy Haul?
Federal legal limits for highway transport are 80,000 lbs gross vehicle weight, 8 ft 6 in wide, 13 ft 6 in tall, and 53 ft trailer length. Any agricultural equipment exceeding any of these thresholds requires permits and enters heavy haul territory. In practice, a wide range of farm equipment crosses these limits:
Combines and Harvester Headers
Modern large combines are among the widest agricultural equipment moved on highways. A Class 9 combine body in transport position is commonly 12 to 15 feet wide without its header. With the header attached, a wide corn head or large grain header can reach 16 to 20 feet in transport configuration, making combines one of the most frequently permitted ag loads in the country.
Standard practice is to remove headers before road transport. The combine body ships on an RGN trailer; the header ships separately on a flatbed or step deck, sometimes with its own oversize permit for width. This approach typically reduces per-load permit cost and simplifies routing. For short-distance farm-to-farm moves within a region, some states' farm vehicle exemptions allow limited movement without permits, but interstate moves and moves over certain distances always require proper permitting.
Large Row Crop Tractors
High-horsepower four-wheel-drive and articulated tractors — John Deere 9R series, Case IH Steiger, AGCO Challenger — are frequently overweight or overwidth when transported on trailers. A fully ballasted large tractor with wheel weights, fluid-filled tires, and wide-spaced dual tires can weigh 40,000 to 60,000 lbs and measure 10 to 14 feet wide. Tractors with front loader attachments or wide cab configurations may trigger height permits as well.
Planters and Seeding Equipment
Modern row crop planters — particularly 48-row and larger planter units — have folded-transport widths that still exceed legal limits. A 48-row planter folded to its narrowest transport configuration can still be 18 to 20 feet wide, requiring oversize permits and pilot car escorts in every state. Planting season creates a predictable wave of planter transport demand each spring as dealers deliver units and custom operators reposition equipment.
Grain Carts and Handling Equipment
Large grain carts — 1,500 to 2,000+ bushel units — are wide and heavy. A loaded grain cart exceeds the 80,000-lb GVW threshold, and even empty, larger grain carts on wide-flotation tires can be 10 to 12 feet wide. Grain dryers, grain bins, grain augers, and handling towers require oversize and often superload permitting when transported over long distances.
Spray Equipment
Self-propelled sprayers — John Deere R4045 and R4060, Case IH Patriot, AGCO Rogator — are commonly 10 to 14 feet wide in transport configuration and weigh 30,000 to 50,000 lbs loaded. They are typically transported on RGN trailers, with boom sections in folded position. Extended boom configurations on road transport are not permitted — booms must be folded and secured.
Hay and Forage Equipment
Large square balers, round balers, forage harvesters, and mower-conditioners are frequently transported between hay country operations in the Southeast and Plains. Self-propelled forage harvesters — Claas Jaguar, John Deere 8000-series, AGCO Fendt Katana — are wide, heavy machines that require the same oversize permitting and RGN trailer approach used for combines.
Irrigation Equipment
Center pivot irrigation systems, when disassembled for transport, require multiple truck loads and oversize permits for the tower structures, spans, and end gun assemblies. Lateral move systems and large linear pivots require careful transport planning due to the length and width of individual spans.
Permits for Farm Equipment: How They Work
There is no single federal oversize permit for agricultural equipment — like all oversize loads, farm equipment transport requires a permit from every state the load traverses. Each state's DOT issues its own permit, and rules vary between states on thresholds, fees, and escort requirements.
State Agricultural Exemptions
Most states have agricultural vehicle exemptions that allow certain farm equipment to move on state highways without an oversize permit in specific circumstances — often limited to movement within a county, within a set distance of a farm, or on state-designated farm routes. These exemptions apply to farm-registered vehicles and equipment moving under farm plates, not to commercial carriers.
When a commercial heavy haul carrier is hired to move farm equipment, these agricultural exemptions do not apply to the carrier's operation. The move is subject to standard oversize permitting requirements in every state the route crosses. Shippers should not assume that because a neighbor's tractor can move on a road without a permit, a commercial carrier can haul the same tractor without one.
Permit Costs for Agricultural Equipment
Permit fees vary by state and by how far the load exceeds legal limits. A single-state permit for a moderately overwidth ag load typically costs $50–$150. Multi-state permit packages for a combine or large tractor crossing four or five states may total $300–$800 in permit fees. For very wide planter units requiring pilot car escorts in multiple states, total permit and escort costs can approach $1,500–$3,000 for a long-haul move.
Our permit services team handles all state applications, so farmers and dealers work with a single point of contact regardless of how many state lines the route crosses.
Trailers Used for Agricultural Equipment Transport
RGN Trailers for Farm Equipment
RGN (Removable Gooseneck) trailers are the standard for combines, large tractors, sprayers, and forage harvesters. The gooseneck section detaches, the deck angles down to ground level, and the equipment drives on under its own power. This eliminates the need for external lifting equipment at pickup — important when loading in fields, at farm shops, or on dealer lots where crane access may not be available. Standard 3-axle RGN trailers handle loads to approximately 80,000 lbs. Larger configurations are available for very heavy equipment.
Flatbed and Step Deck for Headers and Attachments
Combine headers, planter sections, and smaller attachment pieces that have been removed from the main machine typically ship on flatbed or step deck trailers. For headers, this usually requires oversize permits for width on multi-row corn heads and wide grain platforms. A 40-foot corn head removed for transport is still commonly 10 to 12 feet wide and may require a permit even on its own trailer.
Lowboy Trailers
Fixed-neck lowboys are used for farm equipment that needs the low deck height but cannot drive on (no functioning drive mechanism, or the loading approach prevents it). Some custom harvesters prefer lowboys for specific machines where the low deck height provides a height advantage on routes with low bridge clearances.
Pilot Car Requirements for Farm Equipment
Escort vehicle (pilot car) requirements are set by each state and depend on the load's width and sometimes height or weight:
- No pilot car required: Loads 8 ft 6 in to approximately 12–14 ft wide, depending on state. Many compact tractors and smaller ag machines fall in this range.
- One pilot car (front): Typically required for loads 12–14 ft wide, depending on state. Most combines without headers and many large tractors fall here.
- Two pilot cars (front and rear): Typically required for loads 14–16 ft wide. Wide planters, combines with certain header mounts still attached, and some large grain handling structures require two-car escorts.
- Law enforcement escort: Required by many states for loads over 16 ft wide or over state-defined superload weight thresholds. Very wide planters and large specialty harvest equipment may require a law enforcement escort through certain states.
Escort requirements change at state lines, and the same load crossing four states may encounter four different escort rule sets. Our dispatch team coordinates pilot car arrangements for all moves and briefs each pilot car driver on the route and permit conditions.
Seasonal Planning for Agricultural Equipment Moves
Timing matters significantly in agricultural equipment transport. Understanding seasonal patterns helps shippers book transport efficiently and avoid delays.
Planting Season (March–June)
Planter moves surge in late winter and early spring as dealers deliver equipment ahead of planting. Demand for oversize transport in the Corn Belt — Illinois, Indiana, Iowa, Ohio, Minnesota, Nebraska — peaks from March through May. Spring weight restriction postings (spring thaw postings) in northern states can limit access to secondary roads from approximately late February through April, which affects delivery routing in some farm areas. Planning planter deliveries for February or scheduling flexibility into March–April moves is advisable.
Custom Harvest Season (June–November)
Custom harvest crews follow the harvest north from wheat country in Kansas and Oklahoma in June through July, then into the Corn Belt for corn and soybean harvest from September through November. Combine and harvest equipment transport peaks during this window. Carrier and trailer availability tighten during peak harvest months — September, October, and early November — so booking 2 to 3 weeks ahead is advisable for fall harvest moves.
Post-Harvest Equipment Sales (October–January)
Farm equipment auctions and dealer sales surge following harvest as operations liquidate surplus equipment or upgrade for the next season. This period drives dealer-to-dealer and auction-to-farm deliveries nationwide. Ritchie Bros., Purple Wave, and regional farm auctions produce significant transport demand throughout the fall and into January.
Winter Moves (November–February)
Equipment moves in the southern states — Georgia, the Carolinas, Alabama, Mississippi, Louisiana, Texas — continue through winter with fewer seasonal constraints. Moves in northern states are more complex due to winter road conditions, though most oversize permits remain available year-round on primary highways. Snow and ice on rural secondary roads can limit delivery accessibility at farm destinations during winter months in the North.
Agricultural Equipment Transport by State
Agricultural equipment moves frequently cross multiple states. Some of the highest-volume corridors for farm equipment transport include:
- Southeast to Corn Belt: Georgia, North Carolina, and South Carolina to Indiana, Illinois, and Ohio — dealer deliveries and harvest crew repositioning
- Plains state corridors: Texas, Oklahoma, and Kansas to Nebraska, South Dakota, and Minnesota — custom harvest follows the wheat crop northward
- Midwest to Northeast: Indiana and Ohio to Pennsylvania, New York, and New England — large dairy and cash crop operations in the Northeast purchase equipment from Midwest dealers
- Pacific Northwest ag routes: Oregon and Washington state moves for specialty crop equipment and orchard machinery
R&RM LLC serves all 48 continental states, and our familiarity with the permit requirements along these corridors helps ensure moves proceed without unnecessary delays.
Farm Equipment Transport Safety and Compliance
Equipment Preparation
Proper preparation at the pickup location directly affects loading speed, permit accuracy, and in-transit safety:
- Drain fluids to appropriate levels: Fuel tanks should be at one-quarter or less. Grain tanks should be completely empty. Water-ballasted tires or wheel weights may need to be removed to meet weight limits — discuss this with dispatch before scheduling.
- Fold all extendable sections: Planter wings, spray booms, header lifts, and conveyor arms must be in their transport-locked positions. Anything that can extend must be secured against accidental extension in transit.
- Remove headers and attachments: Combine headers must be removed and shipped separately. Row unit markers, gauge wheels, and accessories that increase width beyond the permitted dimension must come off.
- Verify permits match actual dimensions: Permits are issued based on stated dimensions. If the equipment arrives at pickup in a configuration different from what was quoted — wider, taller, or heavier — the carrier may need to obtain amended permits, which can delay the move.
Load Securement for Farm Equipment
FMCSA regulations under 49 CFR Part 393 govern load securement for all commercial transport. Farm equipment presents specific securement challenges:
- Crawler-tracked equipment (large tractors with tracks, self-propelled harvesters) must be secured with chains rated for the load weight, attached to the machine's frame at designated tie-down points — not to non-structural components.
- Wheeled equipment on RGN trailers must be chocked front and rear and chained at minimum four points.
- Combines with high-profile cab and feeder house assemblies require attention to load height center of gravity on curves and ramps.

Agricultural Equipment Transport vs. Farm Vehicle Self-Transport
Farmers sometimes ask whether it is cheaper or simpler to move equipment themselves using a personally owned trailer rather than hiring a commercial carrier. This is a valid consideration for short moves within a county or region where the farm vehicle exemptions apply. For interstate moves, moves exceeding a few hundred miles, or moves involving equipment exceeding 10,000 lbs, hiring a commercial carrier equipped with an RGN trailer, valid permits, and appropriate insurance coverage is typically the safer and more practical choice. Attempting to move oversize equipment on a farm trailer without proper permits on public highways subjects the owner to significant fines and civil liability.
When hiring a carrier, confirm that the carrier's insurance covers the full value of the equipment in transit and that permits are obtained for the actual route and actual dimensions — not estimated dimensions. R&RM LLC provides itemized permit documentation as part of every move.

Frequently Asked Questions
Does farm equipment require oversize permits?
Yes — most large farm equipment transported by a commercial carrier on public highways requires oversize permits. State agricultural exemptions typically apply to farm-owned vehicles operating locally, not to commercial carriers. A combine moving from Texas to Iowa, for example, requires permits from every state the route crosses.
Can farm equipment be moved year-round?
Yes, though seasonal factors affect routing and scheduling. Spring thaw postings in northern states can limit heavy truck access to secondary roads from February through April. Fall harvest season increases demand for carriers and trailers, so booking earlier during September–November is advisable.
What trailer is used to haul a combine?
Most combines are transported on RGN trailers. Headers are removed and shipped separately on flatbed or step deck trailers. Very large and heavy combines may require multi-axle RGN configurations for weight distribution.
How far in advance should I book farm equipment transport?
For planned moves, 1 to 2 weeks of lead time is standard. During peak fall harvest season, 2 to 3 weeks is advisable. Same-week or emergency moves can often be accommodated — call us to check availability.
