I just signed a contract for a new MF 1533 8X8 Power Shuttle with FEL 1525 and a Howard R300B-150 tiller from an Oregon dealer. I paid $20600. Will the 8X8 allow the tractor to go slow enough for proper tillage? I just started looking at these post in depth and now I think that I paid to much for this tractor and attachments. Also it looks like I should have gotten the 12x12. Comments please.
