I bought a HLA mod#2000 7' front plow with hydraulics last season. It has a central pivot and a single 3" dia. piston and crossover valve, to save from damage to the loader's structure, especially the arms. It has adjustable feet and a reversible cutting edge.It's got large trip springs too. It's designed for the application of front, tractor mounted plow, and has distinct advantages over a truck plow mounted on a FEL. I used rear chains, and loaded tires too, with open station. I like it. It's not a cheap rig, but I bought for the long haul, and it does all I ask it to without a wimper.
