Key takeaways
- Inspect jaw wear, hydraulic condition, rotor bearing play, and frame cracks before buying any used skid steer crusher bucket.
- Many crusher buckets need 20-30 gpm at 3,000+ psi, which puts them beyond standard-flow skid steers supplying around 15-20 gpm.
- Budget jaw replacement as a line item on day one, since worn jaws are the biggest swing factor in used pricing.
- A bucket running 60-plus hours a year typically pays back within a season or two versus rental, while single jobs favor renting.
- Get hour counts, serial plate photos, and service records in writing, and read auction terms for as-is sales and buyer's premiums.
A used skid steer crusher bucket is worth buying when its jaws, bearings, and hydraulics check out against your machine's flow rating, and a bad one can cost more than new once you budget jaw sets. This guide walks the inspection, pricing math, and compatibility checks that decide which side of that line you land on.
What should you inspect before buying a used skid steer crusher bucket?
A used crusher bucket lives or dies on four things: jaw wear, hydraulic condition, rotor and bearing play, and frame cracks. Check all four before money moves, because a bucket that's 70% through its jaw life can cost more to bring back than the discount you saved.
Jaw plates and crushing chamber wear
Jaw plates are your biggest wear item. Measure remaining thickness against the manufacturer's minimum spec, and look for uneven wear, which usually means the previous operator ran material too hard or misaligned the chamber. Ask when the jaws were last flipped or replaced; some models allow rotating them for a second cutting edge.
Hydraulic motor, hoses, and case drain checks
Run the bucket before you buy. The hydraulic motor should spin up under load without whining or dragging. Check every hose for weeping at the crimps, and confirm the case drain line isn't plugged, because a blocked drain blows motor seals. Manufacturer spec sheets for skid steer crusher buckets state required hydraulic flow (GPM), pressure, and operating weight, so pull the sheet for your specific model before you test. If the seller can't produce one, that tells you something.
Rotor or eccentric shaft and bearing play
Grab the rotor or eccentric shaft and check for play by hand. Any visible movement in the bearings means a rebuild. Spin it and listen for grinding.
Frame cracks from shock loading
Inspect the frame welds and mount plate for cracks, especially around the bucket ears. Crushing generates shock loads, and a repaired crack is a crack that will come back. Listings on Crushers Equipment for Sale | BigEquipCo rarely include photos of the mount plate, so ask for them specifically.
How much does a used skid steer crusher bucket cost compared to new?
A new skid steer crusher bucket typically runs well into five figures, while a used unit can land at a fraction of that depending on hours, jaw condition, and carrier compatibility. No single published price list covers every make, so treat the numbers below as illustrative bands, not quotes. Check current historical sales data to see what similar units actually sold for before you make an offer.
What drives the used price up or down
Jaw wear is the biggest swing factor. Jaws close to replacement tolerance push the price toward the bottom of any band, because the buyer inherits a wear-parts bill on day one. Hours on the unit, whether the hydraulic motor and drive have been pressure-tested, and whether the bucket matches common carrier classes all move price too. A bucket set up for a high-flow skid steer with a quick-attach plate sells easier than one needing custom plumbing.
Illustrative price bands, labeled as such
| Condition | Illustrative used band | Notes |
|---|---|---|
| Worn jaws, high hours | Low band | Budget full jaw replacement |
| Mid-life jaws, tested hydraulics | Mid band | Best value for active dealers |
| Low hours, recent jaw set | High band | Approaches a meaningful share of new pricing |
New units hold their price because demand from contractors without used-market patience stays steady. Used pricing moves faster and discounts harder, which is where a dealer flipping yellow iron finds margin.
Will a used crusher bucket fit your skid steer's hydraulic flow and lift capacity?
Compatibility kills more deals than price does. A crusher bucket that ran fine on a high-flow 100 hp machine will stall or overheat on a standard-flow skid steer, and the listing almost never says which.
Flow and pressure requirements to confirm with the seller
Ask the seller for three numbers: required gpm, required system pressure, and whether the unit needs a high-flow circuit. Many crusher buckets want 20–30 gpm or more at 3,000+ psi, which puts them out of reach for standard-flow machines around 15–20 gpm. If the seller cannot produce the spec sheet, walk.
Operating weight versus rated lift capacity
Weigh the bucket itself before you buy. A 48-inch crusher bucket can run 2,000–3,000 lb, and that sits on the front of the machine before you add material. Your skid steer's rated operating capacity, published by the manufacturer, has to cover the attachment plus payload with margin. A 2,500 lb bucket on a 2,200 lb-class machine is a tip hazard.
Coupler and electrical hookups
Confirm the coupler matches yours, whether a universal plate is included, and whether the unit needs a 12V line for gate or magnet controls. If you also move feller bunchers and other attachments, the same coupler check applies across your inventory (Feller Bunchers Equipment for Sale | BigEquipCo).
What wear parts (jaws, teeth, bearings) should you budget to replace on a used unit?
A used crusher bucket almost always needs jaw work before it earns money, so treat wear parts as a line item, not a surprise. Start by measuring the jaw faces: if the profiling teeth are worn past the hardfacing or the jaw plates are thin at the pivot edge, you are buying a rebuild, not a bucket.
Jaw sets and turnaround time
Jaw sets are the biggest single wear cost, and turnaround matters as much as price. Ask the seller which jaw profile is installed, whether spacers or shims for tooth adjustment are included, and how long a replacement set takes to ship. If the seller cannot name the jaw part number, assume a wait. Before you commit, price the jaw set against the asking price and check what a comparable unit sold for on our historical listing records so you know whether the rebuild still leaves margin.
Bearings, seals, and hoses
Bearings and seals fail from hours and contamination, and neither shows up in photos. Ask for hour counts on the rotor or drum, listen for play at the shaft, and check hydraulic hoses for chafe and weeping fittings. Budget for a hose-and-seal refresh on anything with unknown hours; a dealer with rotating inventory should price that into the buy before listing it back out.
Where are used crusher buckets actually listed for sale right now?
Marketplace comparison, including where BigEquipCo falls short
Crusher buckets surface in three places: legacy listing sites, auction channels, and dealer directories. MachineryTrader carries the deepest attachment inventory, though dealers on the forums note pricing there often sits at or above retail. Craigslist and Facebook Marketplace turn up private-seller units cheap, but with no hours verification and no hydraulic-spec confirmation.
BigEquipCo's dealer directory lists rotating yellow-iron inventory from regional dealers, and attachment listings appear alongside carriers so you can check carrier weight against the bucket in one place. The honest shortfall: crusher buckets are a niche within a niche, so active listings on BigEquipCo are thinner than on MachineryTrader. If you need a specific jaw configuration this week, search the legacy sites too.
Auction channels and what they hide
IronPlanet and Ritchie Bros. move attachments fast, and one forum dealer reports never finding relevant inventory locally, so check listings before writing off auctions. What they hide: wear condition. Auction photos rarely show jaw wear or bearing play, so treat every auction unit as a jaws-and-teeth replacement budget until inspected in person.
Is a used crusher bucket a better buy than renting or buying new?
When utilization justifies buying
Run the math on hours, not sticker price. If your skid steer will crush for 60-plus hours a year across demolition, driveway, or aggregate jobs, a used bucket typically pays back inside the first season or two versus rental rates that stack up on every job. The used market also discounts hard for wear: completed auction sales on IronPlanet show attachment pricing tracking closely to jaw condition and recorded hours, so a unit with fresh jaws can land well below a comparable new bucket (past IronPlanet attachment auction results). For a dealer carrying rotating inventory, a clean used unit also resells without the new-unit depreciation hit.
When rental wins
If you need a crusher for one demolition job or a single batch of material, rent. A rental costs a fraction of even a used purchase, includes no jaw-replacement risk, and you hand back the wear. Renting also lets you test hydraulic-flow compatibility on your own carrier before you commit to buying a unit that may not match your machine.
What paperwork and seller questions protect you in a private or auction sale?
Hours, service records, and serial verification
Ask for the hour meter reading in writing and whether it matches the machine's wear: a bucket showing low hours with heavily worn jaws and scored bearings is telling you something. Request photos of the serial plate and confirm it hasn't been ground off or restamped. Ask what the bucket last crushed, since rebar-laden concrete chews jaws faster than plain rock. Get any service records for bearing or shaft replacements, and the original purchase invoice if the seller has it.
Auction terms to read before bidding
Ritchie Bros. Auctioneers and IronPlanet sell attachments as-is, where-is, with no warranty and buyer's premiums on top of your bid. Read the lot's condition report, note whether inspection days are offered, and confirm removal deadlines and storage fees before you bid. On private deals, get the bill of sale to state "sold as-is, no warranty" and the serial number, so the paper trail matches the iron.
FAQ
Can any skid steer run a crusher bucket, or do I need a high-flow machine?
Most crusher buckets need more hydraulic flow than a standard-flow skid steer delivers. Many units want 20-30 gpm or more at 3,000+ psi, while standard-flow machines typically supply around 15-20 gpm. Ask the seller for required gpm, required pressure, and whether a high-flow circuit is mandatory. If the seller can't produce the spec sheet for your model, walk away from the deal.
How many hours is too many on a used crusher bucket?
There's no universal cutoff, because hours matter less than wear. A high-hour unit with fresh jaw plates and quiet bearings can outlast a low-hour bucket with scored shafts. The red flag is a mismatch: low hours paired with heavily worn jaws or bearing play suggests abuse or a rolled-back meter. Get the hour count in writing and weigh it against measured wear.
Do crusher buckets fit standard quick-attach couplers?
Many are built for the universal skid steer quick-attach plate, but not all, so confirm before buying. Ask the seller whether the unit includes a universal plate or was plumbed for a specific carrier. Also check whether it needs a 12V line for gate or magnet controls. A bucket needing custom plumbing sells harder and costs you shop time to adapt.
What size material can a skid steer crusher bucket actually crush?
These buckets are built for reducing material like concrete, brick, and rock into smaller, usable output, not for primary demolition of massive slabs. Output size is set by jaw spacing and tooth adjustment, so ask which jaw profile is installed and whether shims or spacers are included. Feed material matters too: rebar-laden concrete chews jaws far faster than plain rock, which affects your wear-parts budget.
Are crusher bucket jaw plates interchangeable between brands?
Generally no. Jaw profiles, mounting patterns, and part numbering are manufacturer-specific, so a set from one brand rarely fits another's chamber. Before buying used, ask the seller to name the installed jaw part number; if they can't, assume a wait for replacements. Price the correct replacement set against the asking price, since a unit with worn jaws plus an unobtainable jaw profile is a rebuild trap.
