I have a 2003 Husqvarna YTH1848XP with a 18hp Kawasaki twin. I'm having a severe power drain when the mowing deck is engaged (via. electric clutch). It only recovers about 75% power and will not mow uphill or around tight corners.
I've replaced the primary drive belt (to rear hydra-stat drive), new fuel, new spark plugs, new battery. I thought it was bearings in the electric clutch, but that's not the case. All blade spindles spin with minimal resistance (normal?)
I took apart all the electrical connections and blew them out. I'm running out of sources of the problem. Any help would be appreciated.
