I recently acquired a 1988 185 hydro with a 46" deck, from my brother who up dated to a zero turn & this was his back mower to his 277lx so it need some attention.
I set out to get it running replaced the battery and the brake safety switch fresh blades and new hydro fan...oil and filter change.
Well when I was removing the seat pan all went good...but I noticed that a spring was not hooked up on the deck Height knob, (ends seem good).
It is NOT the large lever to raise and lower the deck...Its the smaller knob on the left side as you sit in the seat.
Near as I can figure it is m71614 ...part of spring extension sub m89821 and m71559.
Any help would be appreciated
