Buying Considerations

Start with application fit: operating weight class, hydraulic performance, attachment compatibility, and transport dimensions for the jobs you actually run. For used equipment, review service records, total hours, and condition in high-wear systems such as hydraulics, powertrain components, and undercarriage or tires. Compare location, seasonality, and expected utilization before deciding whether to buy or rent. If uptime is critical, prioritize units backed by strong parts availability and dealer service support.

Dealer Network

FAQ

What service-history details matter most before buying a used excavator or dozer?

Look for documented hydraulic service intervals, undercarriage replacement history, and any major engine or final-drive work. Confirm hour-meter consistency and check whether pins, bushings, and swing components were measured against wear limits.

How should I compare machines that look similar on price?

Compare total owning cost, not list price alone: remaining component life, tire or undercarriage condition, attachment package value, transport costs, and expected downtime risk. A higher-priced unit with stronger records and lower wear is often the better buy.

Which specs should I validate first for production-focused jobs?

Validate operating weight class, hydraulic flow and pressure, breakout force, and cycle-time performance against your target application. Then confirm attachment compatibility and local service support so the machine can stay productive after delivery.
