What owners like and complain about

Echo CS-620P

  • 3.3 kW with a torque curve owners say out-pulls the MS 362 and 562XP in big wood
  • Magnesium crankcase, decompression valve, and X-Series build are genuinely professional grade
  • Handles bars from 16 to 27 inches — one saw covers bucking through real felling
  • Typically $200+ cheaper than equivalent Stihl/Husqvarna 60cc pro saws
  • 5-year consumer warranty is unheard of on a pro-tier saw
  • Responds dramatically to the well-documented muffler mod and retune
  • A vocal minority of owners report very stubborn cold starts after the saw sits
  • Felt air filter setup is widely disliked compared to Stihl's HD2 filtration
  • Drinks fuel faster than strato-engine rivals
  • 13.7 lb powerhead gives up a little agility to the newer 60cc generation
  • 4.2-star / 61%-recommend retail aggregate trails its own CS-590 sibling

Echo CS-501P

  • 10.6 lb dry powerhead is the lightest 50cc sold in North America — roughly a pound under a Husqvarna 545 Mark II
  • Owners moving from 50-class Stihl and Husqvarna saws consistently report more low-end torque than the displacement suggests
  • Captive bar nuts stay attached to the clutch cover, so they cannot be lost in the field
  • Aluminium handlebar with rubber grip, rim sprocket and magnesium-grade pro internals rather than homeowner plastics
  • Decompression valve and translucent fuel tank make starting and fuel checks genuinely quicker
  • 5-year consumer warranty is unmatched on any competing pro-tier 50cc saw
  • About $670 — roughly $240 more than Echo's own CS-4920, which is only half a pound heavier
  • Standard recoil with no spring-assist or i-30 starter, unlike Echo's cheaper homeowner saws
  • Sold through Echo dealers rather than big-box stores, so there is no retail review aggregate to check
  • Capped at a 20-inch bar — step up to the CS-620P if you need 24 or 27 inches
  • Scattered owner reports of an early cracked clutch cover, though not a documented pattern
