As penokee points out, anything is better than nothing.
As for energy to make.. you may want to give it a try.. this was like a 30 minute project.
It was a cheapy 4$ mudflap, cut in half, a 8' piece of that perfed angle iron.. has the pre-drilled holes in it.
A handfull of 1/4 x 3/4 hex head bolts , and a nut and 2 washers per bolt.
A few zip ties, a power drill with a 1/4 drillbit, or 5./16.. and a razor knife.
Cut the flap with the knife.
Cut the perfed metal to make the runner across the front of the hof.. use the scrap as the support bars.
Lay the main bar on the mudflaps placed side by side.. mark the holes about every 6" with chalk.. drill the flaps to match holes in metal.. bolt flaps on.. use a couple zip ties to lace the two halves of the flap together.
On my KK I was lucky.. the lower support for the 3pt aframe had 2 bolts that matched the holes in my perfed metal.. I simply had to ream out the holes to about 1/2 inch from the ?3/8 that they were.. Ran the nuts off my aframe mount.. installed the brackets.. re-nutted with loctite.
Use more 1/4 hardware to attach the main bar/flap to the support bar.. adjust for tire and lift clearance.
I think I spent about 15$ at tsc.. course this was a year or two ago.. might be right at 20$ for the materials now...
