Do post pictures of it!
And you if you can, of your mowing setup. You seem to have a lot of equipment.
I am currently working on three different projects all with a short deadline. My newest straw baler which is fast coming together. My straw rake which I am modifying to put on the front of my 4 wheeler, and a leaf box on a lawn cart trailer to pull behind my Kubota zero turn.
The leaf box is currently a frame work of light metal that I am going to cover with tin. I took a 6' heavy stovepipe fitting and will use it for a transition piece to hook the hose that runs from the blower on my mower deck to the trailer.
The reason I am building this contraption is I have some properties that have a considerable amount of leaves that have to brought a distance to dump. It is just too much work to use the regular bagger on the mower to do it because I have to dump too often. A comparable unit from Tractor Supply was over $1000 on sale a while back. It of course has a motor pulling the blower on it. I am going to utilize the blower on the deck of my mower I and bought a section of hose to run from the mower to the trailer. If it works as I hope it will, I will be out less than $100 for materials to build it since I am going to utilize things I already have to build it. I am building it so that I can easily remove it from the trailer and reinstall it so that the trailer is not tied up with it from now on.
