Hello All.
So, I am a few weeks into using my recently acquired 1998 LT155 and am having an issue with the deck vibrating excessively and making a noticeable noise when running. The engine is running smooth with the PTO disengaged and does not surge or miss a beat. When the deck is engaged, I can not only see the PTO level vibrating a lot, but I can also feel the entire mower shaking and there is a "pulsing" hmm coming from under the mower.
When I purchased the mower I replaced the deck spindles, idler, pulley, sheave and belt with genuine OEM parts. I also removed the TriCycler kit and equipped the deck with the the OEM High Lift Blades as I only side discharge on my lawn.
I initially noticed a difference in the vibration the first time that I used the mower with the repairs made, but it seems like it is vibrating more than ever and the humming from the deck is louder as well. The blades are free of damage and are not bent.
I am not used to or very familiar with mechanical PTO's and am wondering what all could be causing this problem? Since there isn't a typical tension spring pulling on the idler arm, could it be a problem with "weak" spindle breaks which I believe to be what applies the tension to the belt?
I appreciate any help or insight that you might provide.
