Construction details.
After I decided to do the project,I researched some front tine tillers that would be suitable for mounting.The Ardisam Earthquake with a square box frame looked the best,so I found one used and purchased a new one that is a close match.Used 1/4" by 2-3/8" bar stock for the side rails and bolted end brackets on each end.The brackets are 3/8" bar stock bent in a u-shape and slid 3" in and bolted.6" lengths of square tube welded to brackets that slide onto the 2" tool bar and tightened with (3) 3/8" set bolts.I already had a ball mount/drawbar adapter made up for the sleeve hitch,so they welded the tool bar to it,flipped upside down.
For the tiller clutch control,I used a pipe floor flange,pipe,and an un-used lift arm from the front blade project.To keep the tillers engaged I used a pipe hanger and a discarded winch handle that flips over the control handle to keep it down.
The two shields are made from some extra conveyor belting I had lying around.Works good as no dirt was thrown in front of the tillers.
I also cut the two end tines off and slid the tillers closer together as the extra width was not needed to cut the wheeltracks out.The tine shields are overlapped about an inch and a half and bolted together.
Fairly simple project overall.I probably spent more time tearing everything apart for the paint process and reassembly.Total cost around 750 for everything.A lot less than a new pull behind Sears or DR Roto-Hog,and besides,I had fun building it
