Do you use water to clean your XT3? If so stop & use a leaf blower & clean by hand. Purchase a spray can of CRC Electronic Cleaner & a tube of Dielectric Grease. Unplug connections one at a time using cleaner & Dielectric Grease at all electrical connections including battery. Grease by hand all moving parts between tractor & deck & operate
deck switch after throttling up. I use neoprene gloves when greasing joints on tractor.
Let us know how it goes, thanks Mark
