sst steering problem
I have a SST16. Sorry I never posted the fix for my mower, here goes...
I found the problem to my steering was the vacuum line. I had 5 psig of
vacuum at my steering actuators tee & 15 psig vacuum just after the check valve at the engine. After following the line I found 2 sizable holes in it just past the engine compartment. The steering worked like a champ with a new line.
This line leads from the engine back underneath the console on the left side. It is difficult to see (my mower had grass clippings hiding it). I removed the seat deck to follow the line, be sure to unplug the seat safety switch & reconnect when re-installing the seat deck.
