We have changed eveything on our mower as far as maintenance. The one thing it will not do is shut off when you put the throttle to slow and turn off the key. You have to pull out the choke to get it to shutoff and then it either makes a loud noise when it stops or emits blue smoke. What can be the problem.

iFixitI have an older Murray riding lawn mower, whenever I engage the mower the engine dies, otherwise it runs .... My dr feild brush mower ... cuts off when I engage theblades. ... My Huskee only shut off once I put it in drive with the blade engage.
Happened to my Husky..Your mower is equipped with the EPA positive shutoff electrically operated valve on the bottom of the carb..it is designed to stop overflow of gas from the carb when the float sticks.. however when it fails the gas now flows back through the carb and into the cylinders and eventually filling up the crankcase and cylinders.. In stead of to the ground...You can replace it but eventually it will fail...the easiest and best fix is to put a easy to get to shut off valve between your tank and carb..When ever you shut your mower down for ANY reason turn off that valve before shutting it down..put mine on two years ago and hasn't failed me yet...Just need to remember never shut the mower down with out turning the gas flow off....NEVER....it may not fail but when you least expect it WALA oil in the gas...best is to shut the gas off and let it run for 20 seconds or so then shut the mower down..this assures no gas in the carb system cannot get into the oil...hope this helps pass it along to your friends as all newer motors are required to have them...good luck.
hydro-static mowers, you will not be able to push. if it is a gear-driven mower (if you need to put it in 1st, 2nd, 3rd... etc) then you should be able to push it when it is in nuetral. if not, then check the shifter linkage for binding. all riding lawn mowers now have seat switches that will shut the engine down if there isn't anyone in the seat.
Some mowers have a mowing reverse safety switch. That safety will kill the mower if you try to reverse with the deck engaged. Some mowers even have an override button that has to be held while backing up. As for the battery thing, no matter how much you charge a bad battery you will not get it to start a mower if it has a bad cell or two. I would use a multimeter to check battery voltage, but the end result would still be the same, replace the battery.
on most riding lawn tractors you most first disengage the blades before going into reverse moving the tractor stop, put the tractor in a forward gear then re-engage the blades.
if this dose not help please contact me.
Husqvarna uses an electronic clutch to engage the mower deck. When the clutch works itself out of adjustment it will quit working. Sometimes it will blow the 20 fuse and the tractor will continue to run, but the blade won't engage. When you then shut off the tractor it won't crank again until you replace the fuse. When you attempt to engage the blades again, the fuse will blow again.
