I was looking to build a larger cart, something like my PRONOVOST P503 TANDEM AXLE with walking tandem, hyd lift, and rear tailgate opens top or bottom, box is 18" deep with sideboards, 50" wide 70" long, dumps a heaped load of crushed rock with my 982's auxiliary remote hyd outlets, a TOTALLY heaped load of dirt needs a little Jerk to get started. I really wanted to build one with a 2 or 3 stage cylinder but found this lightly used Pronovost for a good price. KING KUTTER makes an identical cart for twice what I paid for mine. It's exactly the right size to pull with my 982. I moved about 15,000# of dirt one afternoon in about 3 hours. Loaded cart with the loader on my SH FARMALL. I had around 60,000-70,000# of crushed granite piled in my driveway one fall I hauled with the Pronovoat cart. The was 10-12 loads in the neighbor's one ton dually dump truck, The cart is rated 3000# and I've probably exceeded that a bit a couple times. SON and I took the sides off and moved a 2000# slab of concrete like it was nothing. It's kinda hard on the tires on the cart turning short on my concrete driveway but all tandem trailers have that.
