We have rubber tired , lawn friendly stump “munchers” that will fit through a 36" gate. Sort of like a “rototiller that chews through wood,” they shred the stump into a pile of dirt and woodchips.

Depending on the location, root flare and surface roots, an example price for a 14" diameter stump would be $80 bucks. The more stumps per job, the cheaper the price gets per stump.
