Pressure washer rolling undercarriage riding mower deck cleaner

I didnt want to spend $45 on one of those rolling undercarriage cleaners to wash under my riding lawnmower deck so I just made this thing to bolt onto a standard right angle lance extension. The bolt hole is 3/8" (10mm) The bolt I used is 5" long (125mm) but it may be different depending on what wheels you use. The wheels I used are 4" (100mm". I only used that size because I already had them. You can use whatever you want. You could probably 3d print some wheels if you dont have any laying around. The axle bolt and nut hold everything together so you will need a sleeve or bearings or something to allow the wheels to spin freely when the nut is tightened down. If that doesnt work for you feel free to open it up in tinkercad and put some bolt holes in it. I ended up making a 2nd version that would sit a little lower or allow you to use taller wheels.
