the collection box is home made to mount on a 4 x 2 Home Depot garden cart, it is made to be pulled or pushed by the pin, and a wooden block which holds the cart to the rear section of the PT thereby allowing the caster wheels at the back to "follow" the PT body either way. the sun cover is simply to allow easier movement for the hose. The body of the finish mower was cut to allow leaf pick-up, or if I wish when mowing to have side discharge, normally keep it blocked for mulching mode. I purchased a Trac Vac turbine with 6 inch adapter.The turbine is powered by the PTO at the same time as the mower, the mower hydraulic feed is adjustable to leave majority of the power for the Trac Vac.
It works.
This year hope to make modsfor improvement.
Lots of luck whoever is trying something, it kept me busy for a while, I have to take it easy at 86.
