Anyone have any opinions on an older Gravely Promaster 50? Remember, before ztrs? They had two mid-mount drivewheels and a steering wheel(tire) in the rear, front mount deck? I'm considering grabbing an older one as a backup machine, and to do cleanups. It caught my eye b/c it's got a 16 bushel Peco vacuum on back. I just don't want to pick up a headache too. Any thoughts appreciated!
