Whatever I want that exists (tree spade, aerator, blade, hoe, FEL, chipper, box blade, auger, tiller, cement mixer) I have, and they work fine. What I don't have are two attachments that don't exist.
1. A swale-cutter that will dig a gentle channel to direct runoff. Picture a rear scoop. Instead of a flat biting edge, it's a shallow "V" to cut the swale. Instead of two side-walls and a rear wall to hold the scrapings for relocation, the inside shape flows the scrapings over and out the two sides. It should have provisions for holding weights, as most rear hitches don't have power-down. One pass and the swale is done. (Could be accomplished with a box-blade set at an angle, but even that would require two passes and a lot of adjustments.)
2. Leaf vacuum. Picture a Billy-Goat-type vacuum driven by the PTO and mounted on the rear hitch. A flex tube carries the debris up and forward to a fixed frame over the front bucket. Curtain-screens on the frame release the outflow air while the debris falls into the bucket. You drive forward or rearward, adjusting the intake height with the hitch, sucking up the leaves. When the bucket is full, you drive to the pile, lower the bucket to clear the curtain frame, and dump.
