Recently, the deck on my 335E ZTR has collapsed and won't raise. I'm assuming something is up with the lift cables, but I'm unclear how to test this. When I look under the mower and work the lift handle, it pulls and releases a spring that is connected to a rod, but the rid isn't connected to anything else, so I have no idea what it SHOULD look like. Can someone with a working Z335E deck clue me in as to what I should be looking for or how to diagnose this? TIA.
