Check and see if somthing is stuck in the pullys.If not check pully see if you have any bad bearings on them.Could be a bad safety switch.If not transmition or rear end problem.
Turn your blades off.
Your clutch has to be engaged when you start your mower or at least my craftsman mower does. If it dies when you release the clutch pedal, it is due to the engine shutoff relay which is wired to the electric clutch. There are 2 wires on the lower left side of the mower that run along the inside of the frame to the clutch. These wires run just above the mower deck belts and connect to the top of clutch. They are so close that sometimes they get entangled with the deck belts causing them to be torn loose or rub the insulation off and expose the bare wire (which will cause it to ground out if it comes in contact with metal). You need to find and inspect these two wires all the way from the clutch to the point they come up through a hole in the frame floor that the engine is bolted to.
The safety switch to start the motor on a Ranchking riding mower is located in the ignition. If the clutch needs to be depressed several times before the mower will start, there might be a problem with the adjustment of the clutch.
This is most likely a blade clutch problem. Many times they short and have to be replaced.
Pull start only
Nope, i can start my 720 without clutch engaged. Its a 1984 720 with the z24 motor if you were wondering
to start with when you push in on the clutch pedal you are disengaging it. Your description sounds like the clutch has clutched its last clutch What if it is not the clutch?
because it is a worthless piece of junk!
sounds like the clutch switch neeeds replacing or cleaning.
Need to know what is moving primary clutch, secondary clutch, can track be moved by hand.
Check the battery for starters
With the ac off your clutch the outer non belt driven part will not be turning. When it is turned on it will start to spin.
