This has been covered before, by memory. The 620 has a more advanced or at least different cylinder. The 590 has a non metallic front handle and a spur sprocket. A rim drive seems at this time only an Echo part and is around $70. They all have spring anti vibe. There is probably more but I do not recall. The guide bar likely is in the more list. None of them have a stuffed crank. The parts sheets or ipl can be accessed from their website. The bore and stroke do not seem in the manual.Ok now I'm confused. Three Echo saws. CS-590, 600, and 620. Price points in the $400, $550, and $650.
What do you get for the additional bucks per model? Seems like the 620 is the one in the market place dollar wise that matches up with a 562...how do they compare head to head?
Due to the price in the title here going into 60cc comparison mode is a diversion.
Stihl in my limited experience (I am not a municipality or such entity) might discount enough to negate the sales tax. Husqvarna the consumer has more choice show specials, black Friday 20%, mail order we will match.... or at least give us the opportunity to quote you.
