I picked up this garden/orchard sprayer years ago as an attachment for a Gravely tractor, but it should fit any similar machine with a front PTO takeoff. It was briefly used, but I soon sold the tractor and this has been in storage since. The sprayer was made by Amerind-MacKissic in nearby Parkersford, PA, as part of their "Mighty Mac" line of high-quality outdoor equipment. It runs off the front PTO of your tractor with the extension shaft that you see underneath in the picture.
I haven't run this in some years, but it did work fine before being put away. The only flaw I see is that the plastic cap on the tank top is broken (likely weakened from UV exposure), but a PVC plumbing cap should make an easy replacement. The boom measures 65" and has 4 nozzles, There's also a separate hand wand for spraying individual items.
Please do not email me to ask whether the item is still for sale. If it is still listed, then the answer is yes
