A little hijack here, how do you feel the 465 compares to a 450 and then a 440? Don't they have the same approx. horsepower?As far as what to charge. You will move a dump truck load of dirt in about 2 mins if your also talking on your cell phone. They are thirsty machines, bear that in mind but you can do an unbeleivable amount of work with one, so price accordingly. I am at $80.00 an hour with mininums. What you can charge is very much regional, but you can quickly work yourself out of money with this machine (by working too fast). I try never to work it by the hour if I can avoid it. Always bid and then watch yourself cut your bid time in half with this machine. Thats how I make money with them.
