Pushing some  snow around this afternoon,  and    just as I dumped  the bucket,  the  amber  warning light came on and I lost all  hydraulics and  transmission.

Got the code   '4431'   which is    "Park Brake"  -   Switch Plausibility Check      So I'm guessing it's   either the    switch, or it's circuit.        My other  skid is a Bobcat,  and  PARK  goes  'clunk'  as  a  pawl  or some mechanical   device  engages  to hold the machine.     This Case  park   is  silent, so   is it a friction brake, or  is it a positive  engagement of  some sort?

So,    left it in the snow bank for now.     I was lucky the arms were high enough to open the door.  Last time I was   'trapped' in a  skid loader,   I bailed out the   emergency  hatch..  not fun  to  do,  nor to put the  glass back in the   molding.  I just hope the arms don't settle  during the night!!!

I'm  about  1/4 mile  from the  shed...  And  according to the  OM,      'moving a disabled machine'  is  possible,  but not recommended.   which for  their sake,  is easy to print.  

I figure to   snag the  rear  hooks,  then  back up to it with a  mfwd.  and tow it  SLOWLY on the snow packed road.   If the park  holds the tracks,     I should be able to  just skid it  along.   The treads  should  pack full of  snow,  and  become fairly  smooth and   slick.   

Oh,  BTW,  the replacement turbo  seems to be working  fine.
