The RUS was also spec'd to have a pan seat.
As discussed in more recent topics it seemed to be a hodge-podge of parts with all sorts of "options" being installed on the line. RUS is probably the most varied basic tractor on the planet. Frankenstein would have it so good.
Ours is the 1964 bone stock, pan seat, no tach, no fuel gauge and only a 540 PTO
As it sat the day we picked it up.
