Heavy Equipment & Generators
Used Caterpillar 320 Excavator: Sell or Buy at Auction
Caterpillar is the world's largest manufacturer of construction and mining equipment, and a major producer of diesel and gas engines and industrial generators. Cat equipment is the most recognizable heavy equipment brand globally, with unmatched parts availability and dealer network creating extremely liquid used equipment markets.
The Caterpillar 320 is a 20 metric ton class hydraulic excavator, the machine that has arguably defined the mid-size class more than any other on the market. It pairs a Cat diesel in the 150 horsepower class with a standard bucket of roughly 1 to 1.5 cubic yards and a standard-stick digging depth in the 22 foot range, giving crews the reach and breakout force for trenching, mass excavation, grading, and truck loading without the transport hassle of a 30 ton machine. General contractors, utility and pipeline crews, and site development firms buy the 320 for its balance of digging power, reach, and fuel economy, while equipment dealers and exporters bid it up for the parts commonality and resale liquidity few competing platforms can match. Several generations circulate in the used market, from the early 320 and 320L through the 320B, 320C, 320D, and 320D2, the 320E, and the current Next Gen 320 and 320 GC, so serial number, hour meter, and configuration are verified before every sale to make clear exactly which machine a bidder is getting. A well kept 320 with low hours, a tight undercarriage, and documented service history draws fast, competitive bidding through KD Auctions' network of 500,000+ industry contacts, spanning domestic contractors and international dealers and exporters alike.

Frequently Asked Questions
What is my Cat 320 excavator worth at auction?
Auction value for a Cat 320 depends on its age, engine hours, overall condition, undercarriage wear, control configuration, and the attachments it carries, such as buckets, thumbs, and quick couplers, so no single number applies across the model line or even across two machines of the same year. KD Auctions offers a free AMEA-accredited, USPAP-compliant appraisal that reports both orderly liquidation value (OLV) and forced liquidation value (FLV), giving you a documented basis before you decide whether and how to sell.
How does the Cat 320 differ from the larger Cat 336, and how do I sell mine?
The 320 is a 20 metric ton class machine built for general excavation, utility work, trenching, and site development, while the Cat 336 is a larger 36 to 38 metric ton class excavator suited to mass excavation, quarry, and heavy civil work, so the two rarely compete for the same job or the same buyer. To sell a Cat 320, call KD Auctions at 480.455.3910. A cash purchase typically brings an offer within 24 to 72 hours, with funds arriving 3 to 7 days after acceptance and removal handled within 1 to 2 weeks. A managed auction runs 6 to 10 weeks from engagement to payout, with onsite dispatch within 48 to 72 hours. Commission is tailored to the engagement and quoted upfront, and most sellers pay nothing out of pocket.
