You've got a much newer version! Very nice!
If my understanding is correct, Paladin bought the the Harley Rake line from Glenmac about 2005 and mine is a Glenmac built, yours is newer and updated, made by Paladin.
Only mentioning this, as I've seen older Glenmac built units for sale which need a bit of TLC.
For mine, I had to replace a critical bearing assembly holding one end of the bottom roller. Even though they didn't build the original rake, Paladin was able to machine the new replacement part in about a week which bolted right up (but the part was not cheap!)
