A 7-inch chipper and an 18-inch chipper are not one machine in two sizes. Different drivetrains, different consumables, different failure bills. And rated capacity is a ceiling, not a cruising speed. Feed a machine at its rated number all day and you are buying bearings early.
So here is what each class actually costs to buy and to keep, using machines that have documented records behind them rather than a spec chart.
7-inch: the Vermeer BC700XL
The BC700XL is the entry point of Vermeer's BC-XL line, 7-inch capacity, disc-style, hand-fed. It is the smallest machine most tree crews will seriously consider, and the used supply is deep.
Asking prices from an August 2026 sweep, model years 2014 through 2022:
- 2014, 868 hours: $6,900, Spring City, PA. The cheapest and oldest unit in the sample.
- 2015: $9,900 at 1,071 hours in Tampa, FL, up to $15,000 at 102 hours in Los Angeles.
- 2017: $9,750 at 974 hours in Pittsburgh, PA, and $14,900 at 1,059 hours in Fowlerville, MI.
- 2020: three Los Angeles listings at exactly $15,000 despite 1,659, 534 and 694 hours respectively, and $10,900 at 856 hours in El Reno, OK.
- 2022: $15,250 at 872 hours and $15,900 at 256 hours, same dealer in Plainwell, MI.
Most of the market sits between $9,750 and $15,900 whether the machine is a 2014 or a 2022. Two useful things fall out of that.
First, look at the 2017 pair: nearly identical hours, $5,150 apart. Now look at that 2020 Los Angeles dealer, who priced three machines identically across a 1,100-hour spread while a seller in Oklahoma asked $4,100 less at comparable hours. Region and dealer pricing strategy are moving these numbers more than age is. Within one dealer's inventory hours sometimes matter, as with the Plainwell pair. Across dealers, they often do not.
Second, and this is the practical takeaway: when a dealer flat-prices his lot, the lowest-hours machine in that cluster is the better deal by default. Reading the listings carefully is worth about a thousand hours of somebody else's wear.
Consumables on this class are the cheapest you will find anywhere. A dealer quote on BC700XL anvils came in at about $210 for the lower and $190 for the side, so roughly $400 for a full anvil set. That is a known number, so treat it as a scheduled expense rather than a surprise.
12-inch: the Bandit 150XP and the volume market
Twelve inches is where most commercial tree work lives. The Bandit 150XP is the entry XP-series machine in that class, and one arborist described it as "just about the same thing as a Bandit 200," running its feed rollers slower for safer operation and smaller chips.
One buying detail on the 150XP pays for itself the first time you need a part: the 86 hp Cat-badged diesel is a Perkins engine wearing a Cat badge. Sourcing through the Perkins parts network is generally cheaper than going through a Cat dealer for the same component. Ask which engine is actually in the machine before you build a parts budget around the badge.
Current asks are scattered. A 2013 150XP is listed at $42,200 in Annapolis, MD, hours not listed. Two 1995 units in Jamestown, TN sit at $8,950 and $7,950, hours not listed on either, and they may well be the same machine relisted.
You will also find 2013-era forum numbers still circulating: roughly $40,000 new, $22,500 for a 2005 with 110 hours, $12,500 for a 2003 200XP with 2,500 hours, $5,000 for a 1992 Bandit 150 with a rebuilt Perkins. Those are twelve-plus years old. They are history, not comps, and quoting them at a seller in 2026 does nothing for you except mark you as somebody working off old information.
The failure to ask about in this class is the feed hydraulic motor. On a related 200XP-class machine, an owner documented a motor that snapped after the previous one had been replaced only six to eight months, maybe a year, before. Under a year of service life in that one case. That is not a fleet statistic, but it is enough that "when was the feed motor last replaced" belongs on your list.
The other one is debris. On a related Bandit unit, dirt working into the feed-roller bearing housing was called out directly as "what eats the bearings." Same story you will hear on every brand: seals and housings decide bearing life, not the hour meter.
18-inch: the Bandit 1890XP
This is production equipment, not a bigger version of what you already own. The 1890XP is an 18-inch disc machine with a twin-disc clutch and a diesel power unit, a different class of hardware from the hand-fed 150, 200 and 250 XP machines.
A 2011 1890XP is asking $54,900 in Wayne, MI from a trusted seller, hours not listed. A non-XP Bandit 1890 shows at $36,500 in Shinglehouse, PA, but that is a different model designation and should not be comped directly against an XP.
The documented failure cluster is the clutch. A full twin-disc clutch replacement on one of these was filmed start to finish: the owner checked the throwout bearing clearance twice, found it out of spec, and went in. His general note on throwout bearings is that they "will pop" when they go. The pilot bearing comes out as part of the same job, once the clutch housing and belt are off.
What is instructive is what else happened in that same service window. A head gasket job on the diesel power unit got done at the same time. On that individual machine, clutch wear and top-end engine work arrived together. One machine is not a pattern. But if you are inspecting an 18-inch unit, check both systems instead of assuming a fresh clutch means a healthy machine.
No dollar total was captured for that clutch, pilot bearing, and head gasket work. The owner's time estimate for the clutch removal and replacement portion was under a day's work for somebody with the right tools. Price the parts through a dealer before you buy a machine with unknown clutch history.
Above 18 inches
Past 18-inch you are into whole-tree and storm-cleanup machines. We do not have documented failure records or verified price comps in that class yet, and we are not going to invent them to round out a size chart. If that is genuinely your work, buy on a dealer inspection and a service history you can read.
Picking your class
7-inch if you are processing brush and small limbs, running one-person or training crews, and you want the cheapest entry and the cheapest consumables. A working BC700XL lives in the $9,750 to $15,900 band, and a $400 anvil set is the routine expense.
12-inch if you are doing daily commercial tree work with a regular crew. This is the volume class, which means parts flow, comps exist, and you can resell without hunting for a buyer. Ask about the feed motor and the feed-roller bearing housing.
18-inch if you have contracted volume that a 12-inch machine is visibly failing to keep up with. Entry is in the mid-$50Ks for a documented XP unit. The clutch is a production-class component and not a cheap swap, so unknown clutch history on an 18-inch machine is a walk-away or a hard renegotiation.
Before you commit
If you are genuinely torn between two classes, rent the larger one for a week on a real production job and count loads. A week's rental costs less than being wrong by one size class for three years.
Then pull the records for the machines you are actually considering: the Vermeer BC700XL for the 7-inch anvil and pricing detail, and the Bandit 250XP or Vermeer BC1000XL for the 12-inch class, where the feed-system failure modes and repair costs are best documented. Whatever the size, get the seller to name the last service date on the feed system in writing before you agree on a number.
