This factory-installed upgrade is an order modification request that will switch the four standard pneumatic wheels and tires with Flat Proof Wheels during production of a new mower. This upgrade will be instead of the stock wheels, two front and two rear.
This item is only sold with a new Kunz tow behind mower. This is a Wheel Upgrade so your new mower comes with Flat Proof Wheels instead of standard tires. This is not a set of Replacement Wheels.
