Exmark Lazer Z Bogging down with pto engaged

Hey Everyone,

I have a 2005 Exmark Lazer Z that runs fine with the pto but bogs down with the pto engaged. Any suggestions on where to look first?

Thank You in advance,
Calvin

Make SURE the engine is running on both cylinders, At idle remove each plug wire one at a time with rubber handled pliers. It should run on one cylinder, If it dies removing one the other side isn't firing......

So bad news it is only running on one cylinder. What would be the first thing to look at to get it running on both again?

Remove both plug wires and spark plugs, Re-install the plug into the wire on the side that's not running. Hold the metal part of the plug to a good ground point on the engine then crank it over, Does a blue spark jump across the spark plug electrode ?

Also..... Houza bout post'n engine model and spec number ?

I'll check on that in the morning and report back. The engine is a 25hp kohler, I'll have to get a spec number for you as well.

Well good news. I got the engine to quit bogging down when the pto is engaged. It needed new spark plugs as one side was really carboned up. Now on to the intermit park brake problem, the mower dies as soon as you disengage the parking brake, only randomly though. Any thoughts?

Read this post; http://www.lawnsite.com/showpost.php...74&postcount=8

You may have to catch it acting up to get a good test or just replace it and see if the problem goes away......

I replaced that switch already as it seemed like the most logical thing to go bad. I looked over wiring but didn't see any cuts or anything broken.

Did you check/replace the seat switch ?

That's the only other one that would make it shut down, Seat switch is little over 10 bux..... The interlock module is closer to 80 bux......
