As I was looking these over it would appear that they are the same except for the addition of the hydraulic clamping system to the 620. Am I correct? Do both of them have the ability to move the base in and out to center it on the grinding stone as it wears (or is you use a slightly different diameter grinding wheel)? It looks like it from the pictures but I would love to confirm that with someone who owns a 520. As much as I like the idea of auto clamping it is not worth an additional $170+ to me.
Also the Oregon grinders are the only ones that have this feature, correct?
Thanks in advance for the help!
