A chipper truck is a specialized work truck built to collect and haul wood chips produced by a wood chipper. It pairs a standard truck chassis with an enclosed dump-style container engineered to receive chipped debris directly from a chipper’s discharge chute. Tree-trimming companies, land-clearing crews, and municipal forestry departments rely on these trucks as an essential part of their daily operations.
How a Chipper Truck Works
When a tree crew fells or trims a tree, they’re left with heavy, awkward branches and trunk sections scattered across the ground. A separate wood chipper (usually towed behind the truck or positioned nearby) grinds that debris into small pieces and shoots them through a discharge chute directly into the chipper truck’s bin. The truck then hauls the load to a disposal site, composting facility, or mulch yard.
A typical chipper truck bin holds roughly 18 cubic yards of material, enough to keep a crew working for hours before anyone needs to leave the jobsite to dump a load. Once at the dump location, a hydraulic hoist tilts the entire bin rearward so the chips slide out, similar to how a dump truck operates. These hoists run on the truck’s own power take-off (PTO) system or an electric-over-hydraulic setup, so no separate engine is needed for unloading.
Main Components Beyond the Bin
Chipper trucks carry far more than just wood chips. The body is outfitted with built-in toolboxes, commonly arranged in an L-shaped configuration along the sides and behind the cab to maximize storage without eating into bin capacity. Chainsaws, ropes, climbing harnesses, wedges, fuel cans, and safety gear all need to ride along to every job, and these compartments keep everything organized and accessible.
Other common features include a roof rack with side-access ladders for securing longer equipment, a rear hitch plate or receiver for towing the chipper itself, and underbody toolboxes for items the crew needs to grab quickly. Higher-end configurations add an aerial bucket lift mounted between the cab and the chip body, turning the truck into a combination bucket truck and chip hauler. With the lift installed, workers can reach high limbs without climbing, then chip the debris and load it into the same vehicle.
Body Styles and Configurations
Not all chipper trucks look the same. The two broad categories are standard rear-mount bodies and convertible designs.
- Standard chip body: A fixed, enclosed bin with tall sides and a rear tailgate. This is the most common setup for dedicated tree crews. The bin is purpose-built to contain lightweight, high-volume material like wood chips without spilling during transport.
- Removable roof chip body: A more versatile design where the roof panel detaches, converting the truck from a chip hauler into a flat-bed dump truck. This “two-in-one” approach lets a contractor haul chips one day and bulk materials or equipment the next, which is especially useful for smaller operations that can’t justify owning multiple trucks.
The truck chassis underneath is typically a medium-duty commercial truck from manufacturers like Ford, Freightliner, International, or Peterbilt. Crews choose the chassis based on the payload they need and whether they want to stay below the CDL (commercial driver’s license) threshold.
Sizing and License Requirements
Chipper trucks span a range of sizes. Smaller units sit on Class 4 or 5 chassis with gross vehicle weight ratings (GVWR) under 26,000 pounds, which means most states allow them to be driven with a standard driver’s license. Larger units push above that 26,000-pound line and require a CDL, adding cost and limiting who on the crew can drive.
For context, the federal resource-typing system used by wildfire agencies classifies chippers themselves by the diameter of wood they can handle: Type 1 units process logs 18 inches or wider, Type 2 handles 13 to 17 inches, and Type 3 maxes out at 9 to 12 inches. The chipper size dictates how fast debris gets processed and, by extension, how quickly the truck fills up. A crew running a large Type 1 chipper generally needs a bigger truck body and a heavier chassis to match.
Who Uses Chipper Trucks
The primary users are commercial tree-care companies. A tree service without a chipper truck has no efficient way to clean up and remove debris, which is why the industry treats these vehicles as non-negotiable equipment. Beyond private arborists, municipal public works departments use them for roadside tree maintenance, utility companies deploy them to clear vegetation from power lines, and land-clearing contractors use them during site preparation for construction.
Wildfire agencies also use chipper trucks to create firebreaks and clear hazardous fuel loads from forested areas. In that setting, the truck often operates alongside hand crews cutting brush and feeding it directly into a towed chipper.
Electric and Heavy-Duty Models
At the smaller end, chipper trucks are everyday work vehicles you’ll see in suburban neighborhoods. At the industrial end, they scale up dramatically. A Swedish forestry research project called TREE is currently testing what may be the world’s heaviest electric truck operating on public roads: a Scania-built wood chip hauler stretching 33.5 meters long and weighing 94 tonnes fully loaded. It carries 36 percent more chips per trip than a conventional truck, cutting the number of trips needed and reducing fuel costs.
The TREE project, running from 2024 through 2026, has set an ambitious goal: by 2030, half of all newly purchased trucks in the Scandinavian forest industry will be electric. While that kind of heavy-transport electrification is still limited to pilot programs, it signals where the industry is heading for large-scale chip hauling.
Chipper Truck vs. Wood Chipper
One common point of confusion: a chipper truck is not the machine that chips the wood. The wood chipper is a separate piece of equipment with its own engine, feed rollers, and cutting mechanism. The chipper truck is the vehicle that catches and transports the output. Some people use “chipper truck” loosely to describe the whole setup (truck, body, and towed chipper working together), but in the industry, the terms refer to distinct pieces of equipment. The truck hauls; the chipper grinds.
