Andrew, perhaps you are referring to one of the canopies that Richard C. built.

I just finished a project that has been on my mind for some time and thought I would share. May eat up some bandwidth so bear with me or delete it if you need too.
Some may remember that last year I built a shade for my 1450, made it to be adjustable, mounted to my receiver hitch for quick removal and used a fiberglass cement mixing tray for the cover.<!-/quote-!><hr size=0></blockquote>

It worked good but this year I decided to build one for my 782 and decided to go a different route. Found out that you really don't need all of the adjustment range as one size just about fits all and you really don't need the quick removal as you leave it on all the time. Also using the reciever hitch mounting tied up the receiver hitch.
For my 782 I wanted it to be solid, not rattle, not tie up the reciever hitch, and not interfear with a Cat O 3 point if I decide to build one. Also I wanted it to look as much like one you would see on one of the older big IH tractors.
I took the standard 782 rear hitch attachment assembly, removed the hitch plate, drilled another hole and welded nuts behind the holes that didn't have them. Built a reciever hitch that bolts with three bolts to the original 782 assembly. I built it long enough to weld on the upper 3 point center hitch assemby if I decide to add it.<!-/quote-!><hr size=0></blockquote>

Here are the 1 x 2 upright posts connected with 4 each 1/4 inch bolts with lock nuts, this is what you need to remove to remove the cab.<!-/quote-!><hr size=0></blockquote>

For the shade part I used a 3 foot by 4 foot .032 gauge piece of alumnium. The hardest part was rolling the sides to get the look I wanted.<!-/quote-!><hr size=0></blockquote>
