Finishing up my Masters in Turfgrass Management as we speak, and mow a few high end lawns on the side. All of my residential hybrid Bermuda lawns are at 0.325"- I'm a turf nerd to the fullest extent!
What height are you mowing the Celebration at, and at what frequency? Depending on the number on blades in the reel (I have a McLane commercial that has 11 blades for putting greens), if you wait too long between mowings it will clog. I would venture to guess you're trying to cut too much off at one time. Celebration should ideally be cut below 1" and at least twice per week if you don't have any growth regulator on it. Remember the 1/3 rule- you only want to cut off less than 1/3 of the blade during each mow, so mow more often if the grass is kept shorter. My McLane is at least 20 years old and still cuts really well, but the belt will slip over time. These mowers weren't made to slog through 2-3" grass weekly, so the strain of trying to cut through all of that grass puts more of a load on it.
We bought a used Jacobsen Eclipse 122 with the floating head and it's a fun machine to run. Cuts really well, stripes like a dream, and the reel speed matches the roller speed so your clip rate never changes. Definitely a Cadillac for a homeowner, but if you're serious about it then a professional greens mower is the only way to go. We got ours from Luber Brothers in Grand Prairie- I think it ran about $1,800 for the refurbed unit. If you're looking for something between the Sears model and the professional models, take a look at Tru-cut.
