You must want to use the scoop commercially.... I have a 3pl scoop here ... it probably holds about a decent wheelbarrow full of dirt/sand/gravel. similar to this:

It's a tip bucket. fiddly to use, but it beats the **** out of shovelling into a barrow. It does work, but I couldn't imagine using it for anything other than "hobby farm" type use. You see, even using it for 20minutes ... your bloody neck is killing you from looking over you shoulder... The trip mechanism is a PITA to use.... My tractor is just a ****ty old IH434 ... it rated lifting capacity of the 3PL is about 1.3tons.... The bucket is quite a bit further out from the back of the tractor ... so say 50% of this ... then you will have the front wheels of the tractor off the ground trying to move it ... and no steering ....
I woldn't even consider it ... You need a FEL !!
