If you’ve ever spent a Saturday dragging brush to a burn pile, you already know why a wood chipper earns its spot in the yard. Windbreak trimmings, deadfall, storm cleanup, corral poles, orchard prunings — a good chipper turns a fire hazard into mulch you can spread or a tidy pile you can haul. But the machine that clears a shelterbelt on a half-section is not the same machine a market gardener needs for pruning cleanup, and buying the wrong one is an expensive way to learn that.
The three basic camps are PTO-driven units that run off your tractor, towable engine-driven units with their own motor, and self-powered walk-behind or commercial rigs. Each has a spot, and the right pick comes down to what you’re chipping, how big it is, and what iron you already own.
This guide walks through capacity, power matching and safety in plain terms, then points you to farmpages.com/ where you can compare suppliers and get quotes. FarmPages doesn’t stock chippers — it connects you with the dealers and manufacturers who do.
Quick answer: Size a chipper to the thickest branch you cut regularly, knocking 15–20 percent off its rated maximum for green or knotty wood; a 75–125 mm (3–5″) unit covers most farm chipping. If you own a capable tractor and chip near the yard, a PTO wood chipper matched to your PTO horsepower and rpm is best value. Chip often or far away, and a towable engine unit earns its cost.
1 What a Chipper Actually Does (and the Shredder Question)
At its core a chipper feeds branches into a rotating drum or disc fitted with hardened knives, which slice the wood into uniform chips. That’s different from a chipper shredder, which pairs a chipping chute for branches with a shredding hopper and flails for leaves, cornstalks, garden waste and softer material. If your work is mostly brush and limbs, a straight chipper is simpler and holds an edge longer. If you’re processing a mix of woody and leafy debris, a combo chipper shredder saves you a second machine.
The number that matters most is maximum chipping diameter — the thickest branch the machine will reliably take. Manufacturers quote it as a max, and the honest rule is to knock 15 to 20 percent off that figure for real-world green, knotty or forked wood. A unit rated for 100 mm (4″) will happily eat 75 mm poplar all day but may stall or kick back on a gnarly 100 mm elm crotch. Buy for the wood you actually cut, not the biggest number on the spec sheet.
2 The Three Types at a Glance
PTO Chipper
Mounts on the three-point hitch and runs off your tractor’s power take-off. No second engine to maintain, lots of muscle if your tractor has the HP, and it moves anywhere the tractor goes. The catch: it ties up the tractor and needs matching horsepower.
Towable Engine-Driven
Its own gas or diesel engine on a road-legal trailer. Tow it behind a truck or ATV, park it, and chip without a tractor running. Popular with acreage owners and crews who move site to site. More engine hours to service.
Self-Powered / Walk-Behind
Compact units with a small engine, often on wheels you push by hand, up through big commercial towables. Great for tight orchard rows and yards where a tractor won’t fit, but capacity on the smaller ones is limited.
Most working farms in the Prairies already own a tractor, which is why the PTO wood chipper is the default starting point out here. But if your tractor is small, always in use, or you’re clearing far from the yard, an engine-driven unit can be the smarter buy.
3 PTO vs Own-Engine: The Real Trade-Off
PTO Wood Chipper
Lower upfront cost — no engine to pay for. Depending on spec and region, a farm-grade 3-point unit often runs a fraction of a comparable self-powered rig as of 2026.
Uses fuel and hours you’re already running. Simple, few moving systems, long service life. Downside: your tractor is committed to the job, and undersized HP means poor feed and stalling.
Towable / Self-Powered
Total independence — chip anywhere, leave the tractor free for other work. Ideal for custom crews, tree services and scattered acreages.
You pay for the engine up front and maintain it (oil, filters, belts, fuel system). Higher purchase price and one more motor to winterize, but far more portable and often easier for a single operator.
Rule of thumb: if you own a capable tractor and chip near the yard a few times a year, PTO wins on value. If you chip often, far away, or want a machine anyone can wheel out and start, spend the extra on an engine-driven unit.
4 Matching a PTO Wood Chipper to Tractor Horsepower
This is where buyers get burned. A PTO wood chipper is only as good as the tractor turning it. Too little PTO horsepower and the drum bogs down, chips choke the chute and you spend your day clearing jams; too small a tractor behind a big chipper can also lift a wheel on rough ground. Check your tractor’s PTO HP (not engine HP) and the required PTO speed — most run 540 rpm, some larger units 1000 rpm. Match both.
| Max chip diameter | Typical power needed | Best format | Good for |
|---|---|---|---|
| Up to 75 mm (3″) | 18–30 PTO hp, or 6–13 hp engine | Compact PTO or small self-powered | Orchards, yards, light prunings |
| 75–125 mm (3–5″) | 30–55 PTO hp | Mid-size PTO chipper | Shelterbelt trimming, acreages |
| 125–200 mm (5–8″) | 55–90+ PTO hp, or 25–40 hp engine | Heavy PTO or towable engine | Storm cleanup, larger deadfall |
| 200 mm+ (8″+) | 90+ PTO hp, or standalone diesel/gas | Commercial towable / self-powered | Tree services, land clearing |
These are working ranges, not hard limits — figures vary by drum design, knife count and wood species. When in doubt, size up on HP: a chipper running comfortably below its ceiling feeds smoother and lasts longer than one worked flat out. Your dealer can confirm the exact PTO requirement, and you can line up several through the forestry equipment suppliers listed on FarmPages.
5 Safety and Setup — Don’t Skip This
Chippers are among the most dangerous implements on a farm because they’re designed to pull material in fast. Respect them and set up right the first time.
- Confirm the PTO shield and driveline guards are intact before every hookup.
- Feed butt-end first and let go — never push with your hand past the feed opening.
- Wear snug clothing, no loose cuffs, gloves or dangling drawstrings that can grab.
- Eye and hearing protection, always; a chipper is loud and throws debris.
- Keep the emergency stop / feed-reverse bar within reach and know where it is.
- Stand to the side of the feed chute, never directly in line with it.
- Keep spare knives sharp — dull blades cause kickback and jams, the biggest injury source.
Never reach into the hopper or feed rollers to clear a jam with the machine running or the PTO engaged. Shut down, let the drum stop completely, and disengage power first. Most serious chipper injuries happen during jam-clearing, not normal feeding.
6 Buying Smart: New, Used, and Where to Look
Whether you want the best wood chipper for a small orchard or a heavy towable for custom work, the smart-money features are the same: hydraulic feed rollers (they save your arms and steady the feed rate), a reversible feed for jams, a rotating discharge chute, and easily replaceable, double-edged knives. Check knife and belt availability before you buy — a machine you can’t get parts for is scrap the day it breaks.
Plenty of good used iron trades hands out here, especially PTO units that see light annual use. When you shop a used wood chipper for sale, look hard at the knives and drum for cracks, check bearings for play, and run it under load if you can. A tired engine on a self-powered unit can cost more to sort out than the discount is worth.

7 Wood Chipper FAQ
What size wood chipper do I need for a farm?
For yard and shelterbelt maintenance, a unit that handles 75–125 mm (3–5″) covers most farm chipping. Storm cleanup and larger deadfall push you toward 150 mm+ capacity and more power. Match the chipper’s max diameter to the thickest wood you cut regularly, then knock off 15–20 percent for green or knotty limbs.
How much tractor horsepower does a PTO wood chipper need?
It depends on capacity. Small 3″ PTO chippers run happily on 18–30 PTO hp; 5″ units want roughly 30–55, and 6–8″ machines often need 55–90+ PTO hp. Always check PTO horsepower and required rpm (540 vs 1000), not engine horsepower, and size up rather than down.
Is a chipper shredder better than a straight chipper?
A chipper shredder handles both branches and soft debris like leaves and stalks, which is handy for mixed yard and garden waste. A straight chipper is simpler, holds its edge longer, and is the better pick if you’re almost entirely processing woody limbs and brush.
Should I buy PTO, towable or self-powered?
If you own a capable tractor and chip near the yard, a PTO wood chipper gives the most capacity for the money. If you chip often, far from the yard, or want a machine any operator can start on its own, a towable or self-powered engine-driven unit is worth the extra cost.
