The newer A frames are intended for long frame tractors and have the mounting rod welded in place. There was no need to keep producing a blade to fit short frame tractors long after they went out of production. They'll still work on the short frame tractors as long as you don't mind an extra 8 or 10 inches of space between the tractor and the blade. Share this post Link to post Share on other sites

So how would you hook it up to the lift arm - seems it would be too far forward to hook it up???? Share this post Link to post Share on other sites
TT-(Moderator) 1,131 #28 Posted January 9, 2010 You would either have to use a lift link that's shaped like a boomerang or install an additional crossmember in the A frame specifically as a lift link attachment point. The 520 models with the forward-swept front axle required a lift point relocation (shown in this picture) to match the rear extension necessary to move the blade forward far enough to clear the front tires when the blade is fully angled. The matching angle lever had a "dog leg" bend to allow the operator to reach it more easily from the seat. Share this post Link to post Share on other sites
