Just bought a used Gravely PM34Z. Built tough and very fast. I've seen several units sell on E-Bay up north at a discount. Winter is coming! New in this area they are $4499. Shop around by phone and see if any of your area dealers are ready to clear stock. Just like car sales.. no one wants to be holding last years model come winter. I'm mowing 1.3 acres in about an hour. I have 30+ big oaks and numerous smaller obstacles. Unit is very easy to operate and only problem I'm having is getting to where I don't spin the tires on fast manuevers. I only have 2+ hours experience mowing with this unit. I just get done too quickly.
