Feed that stalls is a blunt knife long before it is a weak engine.
A chipper is the one garden machine where the cutting edge does all the work and gets checked the least.
Replacement parts
The search opens in the shop that delivers to your country, in that shop’s own language. New parts and used or refurbished ones are two different buttons, because they are two different markets.
Repair it, or replace it
The whole machine
Knives and an anvil are the whole machine, and both are replaceable. A bent rotor shaft is not worth straightening. Both new and used open in the shop for your country.
Chippers & shredders: the failures that repeat
Knives dull from one end and the machine starts refusing branches it took last month. Chutes block before the engine complains, so the first sign is a change in sound, not in speed. And the anvil gap closes as the knives are reground.

The other families
Every machine in the section starts from one of these. Back to the garden hub.
Robot mowers
They run alone until they stop alone. Boundary wire, lifted-wheel errors, blade discs.
Open →
Riding mowers & tractors
Deck belts, PTO clutches, safety switches that cut the engine for no visible reason.
Open →
Walk-behind mowers
The machine that sat all winter and will not start in April. Carburettor, fuel, blade.
Open →
Chainsaws
Chain tension, bar wear, two-stroke mix gone stale, a clutch that drags at idle.
Open →
Trimmers & brushcutters
Line that will not feed, heads that unscrew themselves, shafts that stop turning.
Open →
Hedge trimmers
Blades that jam on green wood, gearboxes that run dry, triggers with two safeties.
Open →
Blowers & vacuums
Loss of air, impellers packed with leaves, batteries that fall off under load.
Open →
Generators
No output at the socket, AVR faults, low-oil cut-outs, dual-fuel changeover.
Open →
Pressure washers
Pressure that drops, pumps that pulse, unloader valves and blocked nozzles.
Open →
Multi-tools & pole saws
One powerhead, many attachments — and couplings that wear where they meet.
