Knives are good, 3 X 5ft.  Tires are bad.  Low-time machine with 3 good frogs.  Repair or replacement of a damaged frog can cost more than the price of this entire piece of equipment.  It's a low time undercutter with hinges and lifting clevises in excellent shape.  This unit could go to work with 65 horsepower of tractor or be low cost replacement parts.  Weed pickers available for nominal extra money.  You can't go wrong with this unit. You can call or text me at 785 657-zero zero zero seven, anytime. Thanks for looking.
