Looking for advice for choosing a PTO HYDRAULIC PUMP

[aczlan]

Aaron or anyone,

Please educate me. My calculations figuring 100' x 200' arena is 20,000sf. A tandem dump truck carries 18 yards of sand = 162 cubic feet of sand. At 4" depth is 486sf and at 8" is 243sf. What I'm coming up with is 41 tandem truck loads at 4 inches and 82 tandem truck loads for 8 inches for an average arena. Am I making a mistake here. I ask because the price point I'm shooting for is more than 41 but much less than 82 truck loads.

I get:
100'X200'=20,000SF
20,000SF*.3 feet (4" depth) = 6000CF/27 (CF/CYD)= ~223CYD/18 Yards/truck= ~13 truckloads
20,000SF*.5 feet (6" depth) = 10,000CF/27 (CF/CYD)= ~370CYD/18 Yards/truck= ~20 truckloads
Personally, I would find someone with a semi dump trailer, or triaxle truck to get more sand per trip

Does the Fingerlakes region have issues with rocks being pushed up from ice lens like here in Wisconsin. Y'all have really good wines over there BTW. The rocks being pushed up here average between 1" to 2" vertical a year and rock picking is time/money expensive. To the point of having the ability to go at 12 inch depth is to be a multiple purpose tool also capable of de-rocking crop fields to include root crops. I believe there's a guy they call Arena Rock Doc that gets booked frequently in the Fingerlakes region, when they can get him, and at 6 inches of screening treatment lasts about 7 years when properly groomed on a schedule.

Around here, most of the bigger farms run something like this to pick their fields (using a 60-200HP tractor to run it depending on the size):

Degelman | Signature Rock Picker
We dont have anywhere near that much movement in untilled soil. Most arenas that I have seen have a packed clay base (I assume with stone dust or similar mixed into it) with sand on top.
Looking at what ArenaDoc uses, I suspect that he is running ~50HP tractors and the key is chewing everything up with the ripper first so that he is working in tilled soil vs packed soil (so he can run 50HP tractors vs 200HP tractors).

Aaron,

Thank you for the kind response. I am designing for my needs, being a gourmet garlic farm, and getting rid of rocks in field really helps with harvesting by reducing labor and machine breakage. So far, I have been lucky and the machines I've invented have worked from the get go. I will be marketing to the small farm community, but also owning horses and having a professional calf roper friend dealing with rocks in the arena, I was hoping to find another market as well. It seems to be a definite maybe??? Again, thanks to all for the input.
