Are you suggesting that it might "tip the 226 over???"
I'm not suggesting anything of the sort. I'm just responding to your clearcut statement "Since the 54 inch was designed for 16HP and up,"
In what book, manual or other piece of literature produced by Colt, Case or Ingersoll do you find any sort of information that the 54" blade was designed for tractors with 16 or more horsepower?
Common sense tells me that if 12 hp or 14 hp will handle it, 16 will also handle it!
Now.... you're backtracking. The statement you made ruled out the use of the 54" blade by tractors with less than 16 horsepower.
The wheel track has nothing to do with it.
When it comes to blades, wheel track has everything to do with it. If you try to use the 44" blade (which is the one designed for the 200 series) on an angle with a 400 series tractor, you will find the wheels of the tractor running over top of the windrow coming off of the blade. Whether you're pushing snow or dirt, such a situation is untenable as it causes the tractor to go on a tilt while compacting the spoil.
The 44" blade was strictly for the 200 series. Case never suggested that it could be used on a 400. On the other hand, Case was in total agreement that the 54" blade could be used on the 222, 224 and 226 as an OPTION.
You have been rather "non judgemental" lately, and it has been pleasant!
