KOMATSU PC50 Mini Excavator

The PC50 is Komatsu's most capable compact excavator in its class — 5-ton operating weight, serious digging performance, built for job sites where space is tight and productivity isn't optional.

Most buyers underestimate how much machine they need until they're mid-project. The PC50 eliminates that miscalculation. With a 33.4 hp Komatsu SAA4D95LE-5 engine, 15,763 lb maximum digging force, and a 12'4" maximum dig depth, it handles utility work, landscaping, and light demolition without a second pass.

What separates the PC50 from smaller compact units:

• Engine: 33.4 hp Tier 4 Final / EU Stage V compliant — no regen downtime on most duty cycles
• Operating weight: 11,464 lb — stable enough for serious grading, light enough for transport without a heavy haul permit in most states
• Maximum dig depth: 12'4" — covers the majority of utility and foundation work without switching machines
• Blade: Optional dozer blade for backfill and site prep built into a single machine
• Cab: ROPS/FOPS certified, air-conditioned option available, large-format monitor with rearview camera standard on late-model configurations
• Undercarriage: Rubber or steel track options — rubber preserves hardscape, steel handles abrasive terrain

Komatsu's KOMTRAX telematics system is standard. That means every hour, every fault code, and every location ping is logged — which matters whether you're managing a fleet or verifying a used unit's history before you buy.

The PC50 also runs Komatsu's load-sensing hydraulic system. Bucket, arm, and boom movements draw only the power the task requires. Fuel consumption averages 1.2–1.6 gallons per hour under typical working loads — lower than most competitors in this weight class.

If you're evaluating a used PC50, pull the KOMTRAX report before anything else. Hours without context mean nothing; hours with a full service record and a clean fault history mean everything. A unit showing 3,000 hours with documented Komatsu dealer maintenance is a stronger buy than a 1,500-hour machine with no paper trail.

The PC50 fits a 20-foot enclosed trailer. One truck, one trailer, no specialized transport — that keeps your mobilization costs predictable job to job.

Verify hours, pull the telematics report, inspect the undercarriage wear. Then make the call.
