My Massey 4250 rear tiller (42" cut) didn't till out my tire tracks after mounting 26x12x12 rear ags, so figured to widen her. Sorry I don't have more pics.....I did, but can't find at the moment. Helping my BIL clear some of his new property, I stumbled on some standard tiller extensions in the fencerow, so the modification started right there. The tiller extensions were the same diameter as my 4250, so just had to weld on tube to them to mate to the tubes on the 4250, which were already drilled to accept extensions. Once extensions were mounted, I had to add thick metal to extend the housing. Got plate steel & just stuck the flat plate through slot in bush hog frame & bent by hand. Then drilled & mounted where OE end caps were bolted, then drilled outers for the end caps. Not made new decals yet, but will before tilling garden this spring. I tested her out before painting & she sure takes out my tracks now! She tills a 53" path.
