Hi I have an exmark 60" lazer z diesel engine. the problem is when i release the parking brake or pull handles up it cuts off i replaced 4 of the safety switches
but still doing the same, checked hydro fluid its full ? kinda short on cash at beginning of season so i hate to take it in. any clue on :confused:this one? thank you

You replaced the switches, but did you adjust them right ? Are there any more safety switches, because that sounds like the problem. Make sure they are adjusted right.

On my Groundsmaster 7210, The control levers have to be in the neutral position before you disengage the brake and vice versa. If one lever is not engaging the switch it will shut down when you engage the brake. They are all in sync

which swtiches did you replace? What is the serial number of the unit? If its a few years old, it may have a mercury tilt switch mounted near the battery tray and those are know to cause the unit to die as soon as the brake is released. Now they have stopped using those and dont even supply them as a repl part because of the epa mercury regulations, so they tell you to just hot wire around it and work solely off the seat switch.

Other than that being a possibility, if you have replaced and set all the other switches (seat, brake, 2-control levers) correctly, it may be a bad kill relay or safety delay control module (the brain that ties everything together)

Post the year/hrs/model and serial numbers. Also, the switches that you have replaced. That circuit is a large loop (end at the control module whitch you have to find), and not that complicated if you isolate it. First thing you should do is bypass the seat switch and see if that's it. If it's an older unit and it has the suspension seat, sometimes the foam will get hard and wont activate the switch correctly. To be honest, the switches themselves are very reliable. The wiring and actuators/adjustments are usually the problem.

Ok after working crazy on this and your suggestion it turned out to be a switch located behind the pto switch $14 item week of going crazy never knew there was a switch up under there. anyway back up and running thanks guys
