How to Transport a Motor Grader: Trailers, Specs, and Prep

You won the motor grader at auction. The county road project needs a Cat 140, John Deere 672, or Komatsu GD655 on the grade by Monday. Or the dealer just texted — your Case, Volvo, or Champion is ready for pickup. However the iron landed on your calendar, the next question is the same: how to transport a motor grader without guessing a flatbed that stacks over-width with the moldboard still shifted out, leaving the scarifier or ripper hanging past the deck, or watching a driver refuse soft ground under a loaded RGN.

Motor graders are their own problem set: long articulated frames, wide moldboards, circle/sideshift geometry, tall cabs/ROPS, and — on many mid-size and larger units — a scarifier or rear ripper that changes length and securement before brochure weight ever does. That geometry changes the trailer call faster than a spec sheet. This Guide covers trailer choice, the legal envelope, travel measurements, hotshot vs flatbed vs step deck vs RGN, a securement-aware prep checklist under 49 CFR 393.130, site access, and what to send for a real quote. It complements our motor grader transport service page — trailer/prep for a grader quote, not a thin rewrite — and our heavy equipment transport coverage.

Why trailer choice matters for motor graders

A compact utility grader on a hotshot is a different job than a production road grader with the moldboard still sideshifted, the circle unlocked, and soft ground at pickup. A blade left out tips you into over-width. An unlocked articulated frame can fold on the deck. A scarifier or rear ripper left down adds length and a securement point you did not plan. No drive-on plan for a non-runner means renting a forklift or winch you did not price. Auction yards add another wrinkle: per Ritchie Bros. loadout policies, the buyer arranges loading, self-propelled equipment is not loaded by the yard, and load-out is daylight hours only. After the sale, transportation is on you — see also best heavy equipment auctions.

That is why Logi starts with travel dimensions, moldboard/blade position, articulation lock, scarifier/ripper status, cab/ROPS height, and whether the unit can drive onto the deck — then matches flatbed, step deck, RGN, or hotshot — not the other way around. For planning ranges (not a bid), see our 2026 heavy equipment transport cost Guide.

The legal envelope (FHWA + state height)

Federal rules do not pick your trailer. They set the Interstate and National Network envelope your loaded combination has to live inside — or you buy permits.

Per the FHWA commercial vehicle size and weight program and 23 CFR 658.17, Interstate maximums include:

• 80,000 pounds gross vehicle weight
• 20,000 pounds on a single axle
• 34,000 pounds on a tandem
• 102 inches of width on the National Network

There is no federal height limit. FHWA notes that state standards generally range from about 13.6 to 14.6 feet. Florida — our home base in Sebastian — caps legal height at 13 feet 6 inches inclusive of load under Florida Statute 316.515. Width on Florida public roads is also generally capped at 102 inches exclusive of certain safety devices under the same statute.

Simple math: deck height + motor grader height in travel position = total loaded height. A moldboard not centered and stowed, or a tall cab, can push height; blade sideshift or wings often trip the 102-inch National Network width even when height is fine. When the combination sits outside legal size or weight, you are in oversize load transport territory — we coordinate permits as part of the move.

Measure in travel position (blade, moldboard, scarifier, articulation)

Guessing dimensions is how a “cheap” flatbed quote becomes an over-width step-deck or RGN motor grader job on load day. Measure the machine as it will sit on the deck:

1. Operating weight — Plate or known operating weight, including fluids, counterweights, moldboard, scarifier, and any still-mounted ripper. Feeds axle loading against the federal 80,000 lb GVW ceiling.
2. Height — Moldboard in the OEM travel/stow position (typically centered, raised, and parallel as specified), cab/ROPS as shipped, mirrors and lights folded if that is your plan. A blade left “almost in” is a common height or width surprise on graders.
3. Width — Widest point with the moldboard centered and sideshift retracted (or removed), plus any lights, mirrors, steps, or wing attachments past the tires. Production moldboards are a frequent 102-inch trip-up when not fully stowed.
4. Length — Tip of the front scarifier (or plow frame) to the rear of the ripper or counterweight with the machine articulated straight for travel. Note any rear hitch, ripper beam, or moldboard extension that adds inches.
5. Attachments inventory — What stays on vs. what you remove: moldboard, scarifier teeth, rear ripper, snow wing, push block, and any circle/blade accessories.

Year, make, model, and serial help at auction yards and dealer lots. Same discipline as our how to prepare heavy equipment for transport checklist — motor grader twists are moldboard/blade travel position, articulation lock, and scarifier/ripper status.

Which deck: hotshot, flatbed, step deck, or RGN?

Deck height bands below are industry-typical planning figures, not FHWA standards. Exact decks vary by manufacturer and axle package — always measure your motor grader and confirm with the carrier. Full comparison lives in RGN vs step deck vs flatbed.

Compact graders often land on hotshot or flatbed when travel height and moldboard width stay legal. Mid-size units with tall cabs frequently need a step deck; heavier production machines often earn an RGN for clearance and drive-on loading. Blade geometry and ripper length push borderline graders up a deck class.

Prep checklist + cargo securement (49 CFR 393.130)

Prep protects the machine and keeps the quote honest. For wheeled or tracked equipment that weighs 10,000 lb or more — and 49 CFR 393.130 covers heavy machinery such as motor graders in that class — accessory equipment must be completely lowered and secured, articulated machines must be restrained against articulation, and the machine restrained against lateral, forward, rearward, and vertical movement with a minimum of four tiedowns near the front and rear (or designated mount points). Lighter compact graders may follow the same section or §§ 393.100–393.114.

• Fluids and leaks — Fix active drips. Fuel at a safe low operating level (enough to drive on if it runs). Follow the OEM transport chapter for battery disconnects and parking brake / travel lock.
• Moldboard and circle — Center, raise, and stow the moldboard per OEM transport instructions. Retract sideshift. Pin or lock the circle so the blade cannot swing on the deck. Do not leave the blade free to sideshift in transit.
• Scarifier and ripper — Raise and pin front scarifier teeth and rear ripper. Accessory equipment must be completely lowered/secured under 393.130 — for graders that means travel-stowed and restrained, not dangling.
• Articulation — Lock the articulated frame straight (or per OEM transport pins). An unlocked hinge can fold under braking and damages the machine and the deck.
• Remove wide or tall accessories when it helps — Oversized moldboards, snow wings, or mirrors that force oversize. Sometimes a second legal piece beats one permitted combination.
• Tires and undercarriage — Note tire condition, duals vs singles, and any loose covers or steps. Soft ground at pickup is a loading risk for heavy wheeled graders.
• Photos — Four sides plus close-ups of scrapes, glass, moldboard edges, articulation pins, scarifier/ripper, tires, and serial plates. Walk the same set at delivery before you sign.
• Runs vs non-running — Say it in writing. Running units can often drive onto a flatbed or RGN; non-runners need winch, forklift, or crane. Undisclosed dead batteries get pickups refused.

At auction yards, have the release ticket and bill of lading plan ready before the driver arrives — Ritchie Bros. will not release unpaid equipment, and the yard will not load self-propelled units for you.

Site access: jobsites, mud, and auction yards

A perfect prep checklist fails if the semi cannot reach the motor grader. Before pickup and delivery, confirm:

• Gate width and swing — a motor grader on a step deck or RGN needs more room than a pickup and gooseneck
• Overhead wires, low tree limbs, and scaffold on the approach (cab/moldboard height still matters even in travel position)
• Firm ground for a heavy tractor-trailer (jobsite mud, soft sand, and steep pads stop RGNs and loaded flatbeds)
• Room to stage ramps or drop a removable gooseneck without blocking the county road
• Load-out hours at auction yards and dealer lots (daylight-only at many auction sites)
• A contact with a cell phone who can unlock gates and move other equipment out of the way

If the motor grader is deep in a pad with no truck access, say so early — we may need a local float or staging on pavement.

What to send for a motor grader transport quote

Send this and we will tell you flatbed, step deck, RGN, or hotshot before you pay for the wrong deck:

1. Year, make, model (e.g., Cat, John Deere, Komatsu, Case, Volvo, Champion), and whether it runs
2. Operating weight and travel length / width / height (moldboard stowed, articulation straight, scarifier/ripper raised)
3. What stays attached vs. ships separately (moldboard, scarifier, ripper, snow wing)
4. Full pickup and delivery addresses, gate width, and ground conditions
5. Date flexibility (and auction lot / release status if applicable)

Ask for all-in pricing: linehaul, fuel, and any permits if oversize. Planning ranges live in our cost 2026 Guide. More on the broker: why Logi.
