# Buying a Used Wood Chipper: The Decision Guide (Price, the Two Failures That Matter, and the Free Tests) > The editorial buying guide the marketplaces do not give you: how to size a used chipper, the feed-system and knife failures that decide the price, the two free pre-purchase tests, and real used price bands by capacity class. Updated: 2026-09-11. Source: Chipper Risk — https://chipperrisk.com/guides/buying-a-used-wood-chipper/ (claims cited to primary sources; see /methodology/). Short version: pick the capacity you actually need, then buy on the condition of the feed system and knives, not the paint. The used-chipper market online is almost all raw marketplace listings and no real buyer guidance. This guide is the decision framework, built from documented failures with the repair quotes attached, and it links to the model-by-model records where every price and failure is sourced. ## Step 1: size it to the work, not the ego Chipper capacity is quoted by the largest branch diameter it swallows, and it maps to price and to how hard the machine has been run: - 6-inch (e.g. Vermeer BC600XL): small towables for light residential and municipal crews. They run hard in rental fleets, so hours matter more than age. - 12-inch (e.g. [Vermeer BC1250](/chippers/vermeer-bc1250/), Bandit 990XP): the tree-service workhorse class. The deepest used market and the widest price spread. - 15-inch (e.g. Bandit 15XP, Rayco RC1522G): bigger drum, more engine, higher caught-in energy, inspect the feed controls hardest here. - 20-inch (e.g. [Vermeer BC2000](/chippers/vermeer-bc2000/)): whole-tree class. Fewer units, larger dollars, and the failures cost the most. Match the class to your real workload. Overbuying means paying for feed-system and engine wear you will not use; underbuying means running a small machine at 100% duty, which is exactly how the feed system gets destroyed. See the [chipper size guide](/guides/chipper-size-guide/) for the trade-offs. ## Step 2: the two failure families that decide the price Nearly every expensive used-chipper surprise comes from one of two systems. Check these before anything else. ### The feed system How a machine grabs and feeds wood is where the money is. Two brand-specific patterns dominate our records: - Bandit, the clutch. Bandit's own troubleshooting guide is blunt: "If not adjusted correctly, the clutch will slip under a load, causing feed problems. A BURNT-UP CLUTCH IS NOT COVERED UNDER WARRANTY!" Owners have reported a Bandit on its third clutch inside 18 months. Test clutch engagement under load. See [clutch vs hydraulic feed](/guides/clutch-vs-hydraulic/). - Vermeer, the AutoFeed electronics. A drifted magnetic-pickup sensor can over-generate signal voltage and damage the main control board (board $850-plus, plus a service call). One live BC2000 listing in our records simply states "auto feed doesn't work." Test that AutoFeed engages and returns feed rollers to neutral under load. See [the AutoFeed electronics guide](/guides/autofeed-electronics/). ### The knives, drum bearing, and feed-pump shaft Knives are a routine replace-on-purchase wear item, a listing advertising "new blades" is telling you the last owner just spent that money. Dull knives raise the power required to chip and increase vibration. The drum/main bearing is a "couple hundred dollars for the part" but the labor and downtime are the real cost, and a Vermeer feed-pump drive shaft that snaps is a $120 shaft the dealer will only sell as a $700 assembly. See [knife and anvil economics](/guides/knife-anvil-economics/) and [drum bearing failures](/guides/drum-bearing-failures/). ## Step 3: the two free tests that catch the expensive failures Both cost nothing and both catch four-figure repairs. Spin the feed wheel by hand (a wheel that spins free can mean a snapped feed-pump shaft), and run the feed system under an actual load to expose a slipping clutch or a dead AutoFeed. Do both before you talk price. ## Step 4: the safety check that is not optional OSHA's data is stark: approximately 78% of fatal chipper incidents involve the worker being drawn into the machine. Before you even inspect, confirm the feed control bar returns the rollers to neutral, the panic bar and the bottom feed stop bar function, and that a disc hood latches closed. A used machine with a defeated or missing feed-stop control is not a bargain, it is a liability. See [chipper safety interlocks](/guides/chipper-safety-interlocks/) and [what the federal safety data says](/guides/what-federal-safety-data-says/). ## Step 5: what used chippers actually cost, by class Real observed used asking prices from our sourced records (every figure links to its listing on the model page): - 12-inch: a [Vermeer BC1250](/chippers/vermeer-bc1250/) ran $5,000 (a 1992 unit) to $17,850 across four comps, with the 1998-2000 cluster at $14,900-$17,850. A newer Bandit 990XP sits around $30,000-$33,000. - 15-inch: a used Bandit 15XP was observed near $62,900; a Rayco RC1522G near $49,900. - 20-inch: a [Vermeer BC2000](/chippers/vermeer-bc2000/) dealer band was $34,900-$54,900 (a bare auction unit went for far less, which tells you condition is everything at this size). Year, hours, and configuration drive the spread far more than brand. A cheap high-hour unit with a tired feed system is not cheaper than a dearer one once you fix it. ## Step 6: check the serial before you wire the money Confirm the serial number decodes to the year and configuration the seller claims, and check it against any recall. The [Bandit serial-number lookup](/guides/bandit-serial-number-lookup/) shows how, and every model record on this site carries its recall status. ## Bottom line Buy the right capacity, then buy on the feed system and knives. The two free tests in Step 3 catch the failures that turn a "good deal" into a five-figure repair. Start from the model records for the machine you are looking at, each one shows the observed price, the documented failure modes, and the recall check, all sourced: browse them from [the brand index](/brands/).
