How to Transport a Stump Grinder: Trailer Weight Ratings and Ramp Requirements

"Stump grinder" covers a lot of machines. It might mean a walk-behind unit a couple of people can wrestle onto a trailer, a self-propelled machine that needs a ramp, or a track grinder that weighs as much as a small car. Because the weight range is so wide, the two things that decide whether you haul one safely are the trailer's weight rating and the ramps, and both change with the machine. Here's how to figure out which trailer you need, meet the ramp requirements and tie the grinder down so it arrives where you are working and not in the ditch behind you.

Know the machine first

Before you think about a trailer, pin down what you're actually hauling, because the category tells you almost everything.

A walk-behind or handlebar grinder is the light end, often somewhere between 120 and 400 pounds, compact enough to fit through a standard gate and to ride on a small utility trailer or even in a truck bed. A self-propelled grinder is a big step up, frequently 500 to 1,000 pounds or more, and it needs a real trailer with a ramp. Larger track grinders run into the thousands of pounds, sometimes several tons, and belong on an equipment trailer with a real ramp or a tilt deck.

Some grinders are tow-behind units, which are their own trailer: you hitch them to the truck and tow them directly, no separate trailer required. And you'll also see stump grinder attachments that mount on a skid steer or a mini excavator, in which case hauling the grinder really means hauling the host machine, sized and secured to that. Sort out which of these you've got first, because it decides the entire plan. It's worth asking the rental which type they carry, too, since many stump grinder rentals are compact walk-behind or tow-behind units chosen precisely because they're easy to move.

Rate the trailer to the grinder

Once you know the machine, rating the trailer is the same math as any equipment haul. Match the grinder's operating weight to the trailer's payload, which is its rating minus its own weight, and leave margin. Pull the real weight from the machine's spec plate rather than guessing off its size, since a compact-looking self-propelled unit can weigh far more than it appears.

Then check the loaded weight, grinder plus trailer, against your tow vehicle's rating, and make sure the deck is long enough with rated anchor points to chain to. A walk-behind rides fine on a utility trailer, while a heavy self-propelled or track machine wants an equipment trailer built for it.

If yours is a tow-behind grinder, the numbers you match are on that unit: its coupler, its connector, its brakes and its loaded weight against your truck, the same as any trailer. It's the least hassle to move, since there's nothing to load, but it still has to be roadworthy and matched to your vehicle. Either way, don't take a small footprint as a sign the machine is light, since stump grinders are built heavy and dense for the stability they need while they cut.

Ramp requirements

Ramps are where stump grinders catch people out, because a lot of them sit low and heavy. The ramps have to be rated for the machine's full weight, first of all, and the load angle has to be gentle enough that a low machine doesn't high-center where the ramp meets the deck.

A longer ramp or a lower deck flattens that angle, and a tilt deck takes most of the transition out of it entirely, which is worth seeking out for a low, heavy grinder. Watch the belly clearance, and load straight, slow and centered every time, since a grinder cocked at an angle on a ramp is halfway to sliding off it.

How the machine goes up depends on the machine. A self-propelled grinder drives up under its own power; a walk-behind or a non-powered unit gets winched or carefully guided up, not muscled. Wet or muddy tires on a steel ramp are a bad mix, so clean them and lay traction if things are slick, because a heavy grinder that starts to slide on a ramp isn't something you stop with your hands. Keep hands and feet clear, and use a spotter. Unloading deserves the same care in reverse, since it's just as easy to lose a machine coming down a ramp as going up, so ease it down under control rather than letting it roll.

Chain it down

With the grinder on the deck, position it over or just ahead of the axles for proper tongue weight, then secure it so it can't move in any direction.

For a heavy self-propelled or track machine, that means the same standard as any heavy equipment: a minimum of four tie-downs, restrained in every direction, using rated chain and binders anchored to the machine's frame points and the trailer's rated points. The cutting wheel is the business end and the heaviest concentrated part, so make sure it's lowered and can't rotate or swing in transit, and secure any guard too. Re-check the chains after the first few miles once the load has settled. Read more about how to chain down heavy equipment, and how to load and secure equipment on an equipment trailer.

A light walk-behind can ride on rated straps rather than chains, but the rule doesn't change: it has to be locked down so it can't shift, tip or roll. Chock the wheels or tracks while you're at it, and don't lean on the machine's own parking brake to hold it, since the tie-downs are what keep it put, not the brake.

Match it to the work

Rent the trailer for the biggest grinder you actually run, and if you're hauling a grinder along with a chip truck, saws and the rest of the crew's gear, plan the whole rig rather than just the one machine.

A trailer that carries the weight but can't load the machine cleanly is still the wrong trailer, so check the ramps and the deck with the same care you give the payload. And weigh delivery for a heavy self-propelled or track grinder, since letting the rental handle the haul keeps your crew cutting instead of loading.

What about insurance and damage protection?

Before towing a rented trailer, contact your auto insurance provider to ask whether your policy covers liability and towing-related damage claims.

Eligible rentals booked through Big Rentals also include Basic Rental Protection at checkout. This added protection can help limit your financial responsibility for certain damage or theft events during the rental period.

For full details on how Basic Rental Protection works, including deductibles, exclusions, and renter responsibilities, review our FAQ and platform terms.

The Short Version

• Figure out the machine first: walk-behind (roughly 120 to 400 pounds), self-propelled (often 500 to 1,000-plus), track (into the thousands), or a tow-behind that's its own trailer
• Match the grinder's operating weight to the trailer's payload, with margin, and the loaded weight to your tow rating
• Use ramps rated for the machine, with a gentle enough angle that a low, heavy grinder doesn't high-center; a tilt deck helps
• Drive a self-propelled machine up, winch a non-powered one, keep the ramp clean, and always use a spotter
• Chain a heavy grinder with at least four tie-downs to the frame, cutting wheel down and secured; a light walk-behind can ride on rated straps
• Rent for the biggest machine you run, and check the ramps and deck, not just the payload
