Nah! Those fenders were kit-bashed from a set of trailer fenders like what you would get from Tractor Supply. They're wider and I needed to raise the fender tray (platform that connects them together under the seat) with some washers to give them enough clearance with the larger tires. They work okay, and give the tractor a nice "feel", plus they'd probably help keep some mud from slinging if it would ever find a way to go fast enough!
Here's a shot from the back as we were fitting the new tires/wheels.
