54in blade subframe is hit by deck attachment arms?
 

I have a 149 with a 54in blade. I push snow uphill and off camber and it doesnt seem to like it much. The mower lift/drop arms keep hitting the subframe arms unless I go on the outside of the frame witht he subframe arms. I sheared the 5/16 roll pin so I stretched the frame arms to fit on the outside to fit between the footrest and frame. Im thinking about makig improvements to the subframe to the "New Style" perhaps I can "shrink" the subframe arms to clear the deck lift/lower arms. Where do these subframes take the most abuse, I've straightened the front hangers(bent out). This is my first blade for the 149. Any suggestions?

:bigthink:

How about some pictures...???

Well, the reason it's hitting is because you modified it. Put it back the way it was. The arms do not go between the footrest and frame as they do on a NF. I can't remember exactly where they wind up, but it's such that they are inside the lift arms for the deck.

Make sure that you don't have the trip function locked out, or you'll bend something. As long as the blade can trip, you shouldn't have to worry about bending anything.

I had the subframe inside the frame per the manual and thats when they hit and broke the roll pin. In the normal travel it hits the subframe, thats why I placed them on the outside and it no longer hits. but am curious as to why.

Ive also got the blade set to trip and the blade in the free float position.

Your subframe must be bent or something. As Roland says, pictures would do a great deal of help here. If it's not bent and installed in the right place, there is no interference.

It was bent, spent 2 hours with the arbor press to get the rear of the arms to clear the lower arms and be true. Pushed snow with it and it was great. Ill be darned if it didnt spread itself back open. So Im gonna brace it like the 316 is and that should stop it from spreading. I not hitting anything with it. The blade never tripped. So I dont understand. I had it about 7 inches apart and it spread itself back to about 8. anybody have the newer 316 nouynt and can tell me what the measurement is inside to inside for the rear cross brace?
