Craftsman mower 917.255520 low deck problem

Is there any way to raise the deck on this tractor. I have done all the adjustments ,but I'm still only to get the front of the deck up to 2" and cutting the grass too short.

Yes tires are correct, did the manual check before, nothing about raising the front of the deck,can only raise the back and use side adjustment to level the deck which is level. There a ping in the front of the deck for removing the deck but no adjustment to move the pin up. I was thinking of drilling to new holes to raise the deck but don't know if that will cause problems. Any thoughts are appreciated.

Check the parts of the deck that the hangers hook to. They may be cracked at the welds where they mount to the deck and peeling upward, allowing the deck to drop.

Under the front end of the mower where the link for the front of the deck connects to the frame.... is the bracket bend back, or is it sticking straight down?

Doesn't look bent,its straight down. There is a big pin and looks like I can move the deck up a notch but the pin is to big for the second hole, can I drill the holes in the deck frame to make the pin fit?
I don't know how to post a picture on

attaching a photo, this is what I'm looking at deck to frame, i was wondering if I made the next hole bigger this would rise the deck or is there a different pin i should use. Sorry i could not rotate photo.

You'e adjusted the side adjusters up as far as they will go? Show a pic of those and that area. The front looks fine.

Looks like I only have one side adjuster to level the deck, will post a photo later.
Should I have 2side adjusters?

No, just one, I forgot. You level the one side to match the other. It's hard to know why a deck is sitting low without being able to look over the mower, checking for problems with the frame, wheels, brackets, linkages, etc... Something is probably bent.

I know what you are saying by not being able to look the mower over. i have looked myself and nothing seems bent. What do you think about my idea of moving the front pin up by making the hole bigger in the above photo? By making the square hole round and bigger to insert the pin.

here is the side adjustment photo and thank you.

But the front is the highest part already, right? Sounds like you need to figure out how to get the rear of the deck up.

No front is the low end, front at 2 inches rear at 3 1/2 inches at the highest setting.

Oh sorry, I should have gone back and re-read. I guess your idea about drilling the holes is the best one so far. Does it have adjusters at the front, and are they adjusted all the way up?

As you can see in the photo, the deck is at the highest setting using the current pin.
my idea is to drill the square hole(below the current pin hole) big enough to fit the pin in which will raise the deck. Will this cause any problems doing this?

Yeah, I meant at the other end of the front bracket where it attaches under the front end. I looked it up by model number and see that there are no adjustments at the front at all, so I would go the route of drilling the holes and see if that's enough to solve the problem. It certainly won't hurt anything.

Wish I could look at it and figure out what's happening. Around here, 3" is near the high mark for grass. St. Augustine and Centipede is mostly what we have for grass.
