Interesting that you bring up this topic...as I've spoken directly to David, the owner of Stinger, and expressed to him the need to build a ride on slit seeder along with a greater capacity than 40-50lbs grass seed. He didn't give me specifics, but alluded to the fact that it's in the works. He did sell Lawn Solutions...worked for Exmark under a non-compete agreement for a few years, helped design the ride on sprayer for Toro/Exmark, and them bolted to start Stinger. I own the Exmark slit seeder and Billy Goat hydro slit seeder. The Stinger slit seeder tops them both and the blades are cheaper to replace.
