YTH21K46 Loud Clunking Sound When Deck Engaged
I just recently bought a Husqvarna YTH21K46 mower. This mower is great, it cuts and runs like a dream. The only negative I have is when I put the cutting deck in gear or push the throttle open quickly, there is a knocking noise that sounds like the motor is loose on the frame.
I just changed out the blades and while I had the deck off, I tried opening the throttle and it still made the knocking noise. I know it isn't the transmission as I had the brake set. It isn't a rod knock as the engine runs great, no knock at all. Just when I start the deck fast or open the throttle quickly.
I can open the throttle slowly or put the deck in gear slowly and it won't make that noise. Anyone have any suggestions what it may be. I will check the motor tomorrow to see if it is loose.
