My 420c with a #62 blade is painfully slow to raise the blade. It takes about 30 to 45 seconds to raise from the ground to full height.

It is in good shape as far as I can tell and is a good bit more powerful than I expected. I have 18 acres in east Tennessee and have plans to use the crawler in the woods to clear som...
