I have a TB110 that's only 2 years old. Only complaint is that when mowing tall damp grass, the grass builds up under the deck to the point that it sounds like the engine is coming apart. Blade is not loose. If I shut the mower off a lot of the grass will fall out and it"ll be ok for awhile. I also installed a washout port which helps a lot. I know I should mow the grass more often and when it's completely dry but in the spring that's not always possible. The grass grows fast and it rains often so I have to cut it when I can. I wanted to try a Gator blade but they don't make one for this mower. I liked this mower when I first bought it so I bought one for my son. He complains of the same thing.
