Common Mistakes When Buying a Wood Chipper

Buying when you should be hiring, or hiring when you should buy – Guide by expert wood chipper suppliers

Job frequency decides which one actually saves you money, and plenty of buyers skip that maths entirely.

Buy a chipper that sits idle three weeks out of four and you’ve tied up capital in a machine earning you nothing.

The reverse mistake costs just as much. Hire a chipper every fortnight for a running contract and the day rates outstrip a purchase price within a year or two.

Track how many days a month you’d actually use a chipper before you commit either way. Buying wins on cost if the answer is most weeks. Hiring keeps your capital free if it’s a handful of jobs a year.

We sell wood chippers and we hire them out, so we’ve no reason to steer you one way over the other.

If you’re not sure which side of that line you’re on, call us and we’ll talk through your workload instead of quoting a price.

Buying on throat size alone

A 6-inch rating tells you the maximum branch diameter a chipper can take. It says nothing about how well the machine holds that rating under real load.

Two chippers with the same 6-inch throat can perform very differently depending on engine size and horsepower. An underpowered machine with the right throat size still bogs down on larger branches, especially anything knotty or forked that isn’t a clean, straight cut.

The stress control system on better machines adjusts feed speed automatically to stop the engine stalling. A cheaper unit without one will clog the machine repeatedly on timber well within its rated capacity, even branches under 6 inches that a properly powered machine handles easily.

Not knowing disc from drum

These are the two main types of wood chipper on the market, and it’s easy to skip straight past the difference and focus on throat size instead.

Disc chippers use a spinning disc with blades mounted on its face, cutting fast and giving a consistent chip size on straight timber.

Drum chippers use a rotating cylindrical drum instead, and generally cope better with awkward or knotty branches that would catch a disc’s flat blade edge.

Skip this question and you can end up with a disc chipper struggling on forked garden waste, or a drum chipper doing far more than a straightforward hedge-clearance job needs.

Disc and drum aren’t interchangeable in performance, so ask which of the two you’re buying and check it fits your needs before looking at anything else on the spec sheet.

Skipping safety features to save money

Cheaper chippers cut costs on the infeed system first, with fewer feed roller safety interlocks, a smaller intake guard, and a slower emergency stop response. None of that shows up on a spec sheet comparison.

Ear protection and eye protection are your responsibility regardless of the machine. Hearing loss from a chipper running for hours builds up over years of exposure, with no single obvious moment where the damage happens.

Check the safety features built into the machine before anything else. Reversing feed rollers stop a jam from pulling a hand in. Proper guarding keeps flying debris away from your face. A responsive control system stops the feed the instant something’s wrong, rather than a second or two later.

At ILH Groundcare we never compromise on safety.

You can expect quality machines that have safety at the forefront of any operation.

Underestimating the maintenance

A wood chipper that isn’t cleaned and checked after every use wears out faster than the spec sheet or warranty period suggests.

Sharpen the blades after every use, check the oil, and take a few minutes to clean the machine down.

Belts and rollers wear with use too, and a flywheel running dirty puts more strain on the whole drivetrain. That extra strain is easy to miss when you’re comparing purchase prices side by side.

Work out the servicing schedule and rough annual cost before you buy, while you can still weigh it against the sale price.

Skip this and you’ll find out mid-contract, when a blunt blade or a worn belt slows a job down that should have taken half the time.

Taking care of your chipper this way keeps the wood chips and mulch it produces consistent. The machine itself runs longer for it as well.

Buying a used chipper without inspecting it properly

A used chipper can be a good buy, but only with a proper check rather than trust in the listing photos.

What to check on the machine itself

Feed rollers should turn smoothly with no play in the bearings. Belts should show no cracking or glazing.

Run the hydraulic infeed and check the response at both low and high speed, since a sluggish response often means worn hydraulic components that are expensive to replace.

Check the hydraulic fluid too. Open the tank and smell it: burnt-smelling fluid signals overheating that’s already done damage elsewhere in the system.

What to ask the seller

Ask why the current owner is selling. A specific, verifiable reason, moving up to a bigger machine for more work, is a good sign. A vague or reluctant answer is worth pressing on.

If a used chipper’s history is unclear, get someone who actually works on these machines to look at it before you buy.

We service Forst, FSI, Timberwolf, GreenMech, Vermeer, and most other major brands at our Cumbernauld workshop, and we’re happy to talk through what a used machine’s condition is worth.

We also sell used machines.

Buying from a reputable seller means every machine on our yard has already been through this same checklist before it’s offered for sale, serviced, inspected, and priced honestly against its condition rather than what a private seller hopes it’s worth.

Ignoring wet or green wood in the workload

Wet or green wood chips very differently to dry, seasoned timber.

It’s heavier, it clogs the machine more easily, and it puts more strain on the blades and engine for the same branch diameter than dry timber ever does.

A chipper tested only on dry offcuts in a showroom can behave very differently on a site clearing fresh green waste.

If most of your work involves freshly cut timber, ask specifically how the machine handles it wet before you buy.

Choosing power source on price alone

Electric chippers, sometimes sold as garden shredders with an electric start, run quietly, need little upkeep, and suit a small garden well.

Daily trade use is a different, heavy-duty demand entirely, which is why petrol and diesel make up the whole of our range.

Petrol chippers are lighter and simpler, useful if you’re moving between several jobs a day. Diesel costs more upfront but delivers better fuel economy and torque for sustained heavy chipping.

Pick whichever’s cheaper on the day without checking it matches how often and how hard you’ll actually run it, and you’re the one who ends up wishing you’d spent a bit more.

Overlooking parts and after-sales support

How fast can you actually get parts when a blade chips or a belt snaps mid-contract? That question matters more over the life of the machine than the purchase price does, and it’s easy to skip past it while you’re comparing prices on the day.

Some dealers sell machines they don’t service, leaving you to source parts and repairs elsewhere once the sale’s done.

We stock genuine Forst and FSI parts at our Cumbernauld workshop specifically so a breakdown doesn’t turn into a week of downtime waiting on an order.

If clearing the stump alongside the felled timber is part of the job, ask about stump grinders at the same time.

Buying chipper and grinder support from one specialist dealer saves chasing two separate suppliers when something needs fixing.

Getting the decision right the first time with ILH Groundcare

Every mistake above costs less to avoid than to fix once the machine’s already on site.

If you’d rather talk it through with experts than guess, call us on 0141 775 9288 or get in touch online.

We’ve been supplying, hiring, and servicing chippers across Scotland since 2007. We’d rather steer you to the right machine than sell you the wrong one.
