I have a NH 488 that I bought new in 1990 , and I use the regular guards, and I can cut anything. The knife sections need to be in good shape, but just as important is that the section makes close contact to the guard. Mowers cut just like scissors do, if the gap between the knife section and the guard is too wide, the grass will not cut off , it will pull through the guard, and plug the knife. Old mowers had replaceable ledger plates on the guards, modern guards just wear out and need to be replaced. When I used a mower many years ago, I recall sharpening the knife, and replacing hold downs to keep the knife done firm against the cutter bar, and also to make certain the guard tops were hammered down to keep the knife sections running through the guards with the minimum clearance possible. I dint you need to switch to stub guards, just find someone that understands how the machine should work, and set it up properly.
