I have a 96" buhler/allied behind a kubota M108 and have had it for a dozen years or more. Works real well. Been through a few shear bolts but that's it.
When feeding it a full swath I still have to clutch some or it drags the engine down.
On a side note if you happen to leave a 16kg bag of cat food next to barn door and it storms over night.... the magpies are extremely happy after you feed that through the blower.
