Yes indeed I have one mounted on a 140 and use it for lawn as well as some tall grass clipping. The entire unit works very well. I consider it an immence improvement over the cub with a 5 ft. mower. The only draw back I've detected is a slight tilt to the cut swath if cutting across a slope instead of up and down the slope. I would certainly recommend one. The 306 mower does a better job of scattering the cut material than the C2 mower on the Cub.
