Laying Road Base
Depending on the area to be covered get a bucket of road base (the smaller the area to be covered the less road base required). In first gear slowly crowd the bucket forward until you can hear the road base falling, keep driving forward, tapping the joystick into the dump position as you go (try using the back of your hand).
Laying Road Base in a Decline
It is the same in the decline as a level drive however going down hill, gravity will take over so you may not have to tap the joystick as much.
