Here is one of mine: Implement: Bobcat 5 shank scarifier with depth skids. Problem #1: Not wide enough, 7ft wide machine with 3ft wide rip path. Fix #1: Replace depth skids with shanks and add 1ft to each end and add 2 more shanks for a total of 7 shanks. Performance: 10" spacing between shanks creates furrows because of the firmness of the dirt. Two passes are required, this is not acceptable. Fix #2: Cut 6" of each end, cut new shank holes and fab/weld new mounting tabs between existing holes and tabs. Purchase another scarifier, cut off all the parts not needed, Add 1ft to each end, weld face to face with 4" solid stock between the two. Shank spacing is now on 5" centers. Replace shank bolts with shorten and redrilled hitch pins for quick removal. Perfomance: Perfect 7ft wide swath of deep ripped soil with one pass. I have to deep rip the track about every third weekend. Sorry about the 1/2 ton in the background.
