When I turn the key on my riding mower the starter acts as if it needs more juice. The first rotation of the engine is slow and then it acts normal. Starter, solenoid, or what. Battery is fine.
Clean and check all your battery connections , your starter may be getting old and worn if all connections are good - not the Solenoid if it's kicking the starter over or the ignition switch

Unless you have sealed off the battery cables to prevent water ingression then all of that pressure washing ( which is the most destructive thing you can do to a mower ) has probably caused the battery leads to corrode under the insulation .
Mowers should be blown down not washed down as grass clipping adsorb water and compact when hit with a pressure washer
Unless the mower is stone cold then water will sit on bearings then get sucked in as they cool and the air inside contracts .
