MY YTH 2348 Huseqevarna mower has started "clanking" and losing power in mid-size grass; it also started clanking a little when I first start the engine, with the deck disengaged. When it clanks in the taller grass, I disengage the deck and the mower regains power and the clanking stops. Help!
NOTE: the mower still mows the lower grass without the clank and the loss of power. There are no obstructions in the deck to prevent the blades from turning.
