# Carlton 1712 Used Price & Common Problems | Chipper Risk

> Carlton 1712: one used listing at $36,000. Documented problems: feed-wheel drive gear and disc / main bearing. What to inspect before you buy.

**Verdict:** inspect

One observed used comp: 2022, ~400 hrs, $36,000 (new-unit reference $75,420). Carlton-specific failure data is scarce, so the risk profile leans on disc-chipper class analogs, honestly labeled. Held as research pending more comps.

**Observed used price:** $36,000–$36,000

**Documented failure risks:**
- Feed-wheel drive gear: Disc-chipper class analog: on an Altec disc chipper a stripped feed-wheel drive gear caused chute jams and was replaced twice in a week. Not Carlton-confirmed, verify the feed-wheel drive engages smoothly under load.
- Disc / main bearing: Class-level cost analog: a new disc bearing part runs "a couple hundred dollars," but labor and downtime are the real cost. Inspect for disc runout and bearing noise.
- Chipper knives / anvil: Disc chippers throw poor chip quality and load spikes when knives dull, inspect knife edges and anvil clearance.
