I have a T-250 and want to adapt a 3 point 6ft box blade and also a 7ft dozer blade made from an old road grader blade and oil well casing. Both tools will only be welded up in a fixed position with no tilt or angling involved and will be used on the farm for moderate/light duty to make some new waterways for erosion control - not on stumps, roots, etc. I've noticed the plates come in 1/4 through 1/2 inch and some are solid across and some have a pair of mounting plates with a horizontal bar in-between. Would appreciate input from anyone who has made up anything from old 3 point or other farm tools and adapted to quick attach/Bobtach.
