You need a tilt hitch and a wide bucket to clean up the floor as you go so its nice and smooth, and also another unit to cart material, there's a lot of downtime on the machine waiting and those 325's can move material in the right hands and the job set up properly.
Appreciate the feedback, sounds like you have moved some dirt before., The guy I had doing the work for me usually just takes larger jobs..He just fit me in as a favor. but was fair on the $$$. Needless to say I didn’t get his full arsenal they were on bigger jobs.
This dude does not know about managing time and fuel. Have the truck beside you not directly behind you that way you don't have to swing 180 degrees every scoop. Go ahead you do the math...
