Hello, I have a Z-Force 50 about 3 years old 275 hours. Its well maintained. Today I went to get the last mow of the season in and when I take off the brake she stops. I suspect the seat switch, I unplugged and jumpered it but it acted the same way. Is there a diode in the switch where that isnt a valid test? Is there a way to disable that for certain so I can determine if its the switch? I am familiar with the mower and am pretty mechanical. Procedurally, open the sticks, brake on, engine fires. Take in sticks and engine stops or take off brake engine stops. Looks like a good technical group here so I expect someones seen this. Mower serial 2G145Z00070 Thanks!
