no, its a 702 blade made for the 1500-1600-1700 tractors. bolts on the frame using some of the engine bolts and on the front below the hood hinges. i can't find this power beyond website. do you have a link?
found this picture. the one in this picture appears to have a lower mount going back towards the footrests. the one i have came off a tractor was dealer installed. i wonder if the one in this picture is modified.
the one in your second pic uses the same connection points (FEL attachment)as the NH full frame backhoe on my 1720. Wouldn't hurt to run some extra steel to those points if yours doesnt IMO.. that's a great attachment btw
use the search feture on the top, not working for me at the moment, but all the info is on this very site.... (only the best tractor site on the www) TractorByNet.com - Search Forums
