I have a wright stander fixed deck also the deck is 61 inch. ( about 5 years old) today the crew was cutting grass and the mower started to slow down.. the driver shut it off and called me saying he thinks it is low on hydro fluid... I met them at the lot took the cap off and it was low so i added fluid untill full. i started it back up let it run for a little bit and it will not move at all. i called a local dealer they said the pumps and the motors went bad proble but it did not run out of fluid... 1. is there something i have to do when it runs really low? ( leveler to bleed it) 2. the safty switch i spilt a little fluid on it could i have messed it up? anything will help guys thank you.
