Hi Everyone, I love my grasshoppers am looking to add another machine this spring. Currently running a 2012 329b and a 2011 729b (both 29hp Briggs Big Block). I am looking at the 325D and was looking for some firsthand accounts of fuel usage on both machines. I am wondering if the diesel will pay for its self just in fuel savings compared to my Big Blocks. Also is the rear frame behind the wheels longer on the 325? I have to go up the gate on my Isuzu diagonally with the 329 to keep from bottoming out on the ground.
