Those little ditches aren't like those "little mountains" you have around that area, are they? I went up to Harrison to pick up a bandsaw and missed the exit for Hwy 65 out of Conway, so I just kept going and took Hwy 7 out of Russellville. Sure glad it was daylight and I was empty cause that is one winding road with no room for error.
Back to the topic at hand.
I have a Steiner with the smaller of the two blowers offered and it will move pretty much any item that a large backpack type of leaf blower will move, except I get to sit down while doing it. ( allowing for more ground to be covered comfortably)I have seen but never used the larger pto blowers for tractors and figured one of them would move as much or more air than my Steiner (however RPM is lower on the tractor model). Might be worth investigating. If the volume of air is there, but not the pressure to move the gravel, a simple slit type of reduction nosecone would probably "aim" the air and allow for it to move larger rocks and such.
I know there are some pretty good sized rocks out there, which is the reason for my concern, as my Steiner moves everything in it's path here.
