Welcome to JUST ANSWER small engines, let me try to help you !! Do you have a voltmeter to check the battery and cables? Electric clutch dropped out from low voltage. Now engine won't crank. Look at the battery and the ignition fuse behind engine, near the starter solenoid.

Engine was running when it stop mowing when I park it and shut it off . when I try to start it it wont
Expert:  Curtis B. replied 2 years ago.

Check fuse and battery!

Customer: replied 2 years ago.
I have check the yellow fuse 20 amp is ok . what about relay it looks like it is connected to switch for clutch
Expert:  Curtis B. replied 2 years ago.
Follow the positive battery cable to the starter solenoid, then use old screwdriver to jump across the solenoids two large terminals to see if the engine will spin. This is quick test of battery. cables and starter. The electric clutch is not going to engage if there is no voltage.

Engine turns over just fine. There is a relay in the clutch circuit just down from switch that puts clutch in gear part # ***** could this be bad?
Expert:  Curtis B. replied 2 years ago.
Sorry, you said it won't start, I thought you meant the engine. You mean only the clutch does not engage. Yes, there is a relay that the pto switch has to close to send battery voltage to the clutch. Do you have voltage to the clutch wires? If you have voltage to the clutch, the clutch may have failed. No voltage, switch or relay problem.
Customer: replied 2 years ago.
When you pull switch out you should be able to hear clutch click I do not hear that. being that I was mowing the grass and the clutch disengaged engine was running until I shut it off. It is acting like I left the clutch engaged when I shut it off
Customer: replied 2 years ago.
I am going to go to John Deere and get relay will get back to you when I replace relay.
Expert:  Curtis B. replied 2 years ago.

OK, thanks.

Customer: replied 2 years ago.
Put new relay work all of 1 min. Engine runs but will not engage clutch
Expert:  Curtis B. replied 2 years ago.

If you have no voltage to the clutch from the new relay, the clutch may be drawing too many amps.

Expert:  Curtis B. replied 2 years ago.

Anything over 5 amps is to much!

Expert:  Curtis B. replied 2 years ago.

Clutch may be bad and have to be replaced.

Customer: replied 2 years ago.
clutch will engage if you hold down the pio switch that the switch that lets you mow in revers.
Expert:  Curtis B. replied 2 years ago.

RIO switch. Locate the reverse switch that cuts out the blades. It may be stuck open, keeping power from getting to the clutch. You bypass it when you use the Rio switch

Customer: replied 2 years ago.
were is that switch located
Expert:  Curtis B. replied 2 years ago.

# ***** switch, looks to be on the side of the frame where the reverse pedal hits it.

OK will be working on it tomorrow.
Expert:  Curtis B. replied 2 years ago.

OK, thanks.

Customer: replied 2 years ago.
spent all day replacing pto switch check all wire connection and got no where seat switch works reverse switch works clutch is only thing I can think that is causing the problem. when you have the ignition switch on the clutch will click some times and sometimes not.I have voltage to clutch.
Expert:  Curtis B. replied 2 years ago.
Wires to the clutch ok? Not damaged or a bad connection? Clutch should click each time switch is flipped. Clutch is a non adjustable model, so there is nothing to change at the clutch.
Customer: replied 2 years ago.
What I do not understand is why the clutch will engage when in reverse and I hold down the pio button as soon you release the button and are still moving in reverse it will disengage if I push the button it will reengage. I have order the clutch but I really do not believe the clutch is bad.
Customer: replied 2 years ago.
Also is there that the old clutch may have a short and damage the new relay
Expert:  Curtis B. replied 2 years ago.

Maybe the rio switch is bad!

Expert:  Curtis B. replied 2 years ago.

Customer: replied 2 years ago.

Rio is a momentary contact switch it test just find
Expert:  Curtis B. replied 2 years ago.

Are the wire connections to the switch good?

Customer: replied 2 years ago.
Expert:  Curtis B. replied 2 years ago.

Did you bypass the rio?

Customer: replied 2 years ago.
that switch is good it is open in its normal position and close when you push it in. I have not work on it today have guest from New Jersey but will be looking at the seat switch it not only kills the engine but I thing it disengage the clutch when you get off the seat
Expert:  Curtis B. replied 2 years ago.

Seat switch will kill engine, but not clutch.

Customer: replied 2 years ago.
As far as I am concerned you did not help me. I am calling John Deere I have replaced everything that you said and the mower still does not work.
Expert:  Curtis B. replied 2 years ago.
Sometimes it is better to leave it to the professionals. I would really like to know the outcome.
