So i recently had no issues with my lawn tractor (5 years old) model number 917.28861 54"deck.
Did a full tune up on the mower.. ran great but then i engaged the blades and there was a lot of knocking and vibration coming from the deck
Finally i realized one of the blades wasnt in the star pattern enough and stripped the mandrel, So i replaced the mandrel recently and put the new blades on.
Engaged the deck and same still a ton of vibration. Checked all the pulleys everything checked out.. i replaced the 5 year old belt figured there was not enough tension.
Engaged the deck.. same vibration.. just maybe a tad less.. Took off the blades.. Engaged the deck.. Vibration.. I honestly cant figure it out? im going under the tractor
again today after spending 12 hours on it yesterday.. to check the main pulley under the motor? maybe that has something to do with it.. im just checking for looseness...
Any help would be great..?
