Hey that's pretty decent they're giving you a new hood.
I know the hoods were a weak link when I got our 2550 so I always babied the hood ...that is I kept a guiding hands on when opening/closing.
Anyways the other day after mowing and before turning off the mower the hood wouldn't open for me. After mowing I
ALWAYS idle down a good minute and open the hood
before turning off the engine since reading about a backfire that started a tractor on fire.
Not that the tractor backfires but it's such an easy precaution to take to prevent a catastrophe that I'm not taking any chances.
As luck would have it seems my hood is starting to go because it was binding between my forefinger and thumb.
I was fortunate to have this paint stir stick laying close by and was able to open it with very little manipulation. I did some mowing with the stick inserted like you see for ease of lifting the hood and it worked fine.
...as an aside a token look under the hood revealed no easily detectable loose fitting that I could tighten up. I'll most likely just use this crude but effective fix until the hood breaks because...
...that's the way I am

and I never liked the way the hood tilts back anyway.
