**Verdict:** insufficient-data

Hobart D300: documented failure points, real repair-part prices, and used-market pricing for buyers and owners.

**Observed used price:** $1,249.99–$4,250

**Documented failure risks:**
- Planetary center bolt / seal: Parts Town's Hobart mixer troubleshooting guide identifies a loose planetary center bolt as a common cause of squeaking/grinding noise, requiring the bolt to be re-tightened and the planetary lifted back into position; a dried-out planetary seal is the other common noise source.
