My driveway is over 1/2 mile long & pretty steep in 2 areas. Got some loads of crusher run yesterday & was talking to the delivery driver & he said I should rake as little as possible since it allows the fines to go through the rake tines & that a rear blade is better b/c it moves all the aggregate & doesn't separate. Once separated the it doesn't pack as well & the fines can was off easier, especially on the hilly parts. I've only had this place a little over a year now so I'm still new to DW maintenance, does this sound right?
