Hi,

I have a Ferris IS500z that I bought in 2007. The mower was running fine until yesterday when it started to stall when I cranked up the throttle past 50%. I rode it back to my shed and shut it off and now I don't even hear the solenoid click when I turn the key. I'm guessing it's a bad solenoid but I need to diagnose it. I'm also wondering how much time I have left on this machine. The 24 HP Briggs engine has 542 hours on it and is leaking quite a bit of oil which I top off as needed. The engine area is a dirty, oily mess and I'm handy but not handy enough to pull the engine out or do any major work on it. Aside from the engine and the mess created by oil and hydraulic fluid, the machine is in great shape. I'm wondering if it make sense to, at some point, find a reliable service (won't be easy in central NJ) to fix or replace the engine or would that be time to replace the mower? I don't know how much it would cost to fix or replace the engine but a new machine is pricey and it seems wasteful to dump the entire machine if the engine can be replaced.

In short, given the shortage of good local mechanics and the cost of fixing/replacing an engine, when would you declare the machine's life ended?

Lets start with the actual 7 digit model number from the model number tag since there are 17 different models of the IS500Z. And then also get the model number info off of the valve cover.

I suspect the run and or start issue is related to the battery/charging system. Also if it is the engine I am thinking most likely has a leaking sump gasket. And 542 hours with proper care should be about the half life of that engine.

Thanks for the quick reply. The model number is: 5900640

Turns out a fuse was blown in the starter circuit so it runs now. I checked the fuses visually earlier but the fuse that blew wasn't very transparent so I missed the gap. A multi-meter detected it.
