As I am already on my journey through the Eighties, I purchased my PT422 to make some tasks which were never any problem, a little ( spelled LOT ) easier. I selected forks, and an LM bucket to move things, and a minihoe to dig , and of course the 48 inch finish mower gives me a riding mower.
However, today was one of those times when I had to improvise.
A bundle of shingles is much heavier now, than when I was younger and the PT was about 30 inches short of the mark, to help me place the shingles on to a shed roof.
An inverted saw horse clamped to the forks, and a piece of ply screwed to the horse legs did the trick.
I guess you caould call this an attachment attachment.
Enjoy your PT to the fullest. Bill
