Engine cutoff when PTO switched to ON is an operator not in seat state. Check operation of seat switch.

Check the solenoid contacts on the starter motor, Poor contacts will cause a no start

flexible wire outer case , bend the case and allow wd-40 to penetrate to the steel wire inside plastic covered allow the wd-40 to dun down the wire all the way throufg replace the cables

Question edited for clarity, Cub Cadet, not 'club cadet', and added 'what it is.Question moved to the correct category.Sounds like you have clutch and drive problems. Take it in for service.https://www.google.com/search?q=i1046+cub+cadet+can%27t+disengage+rear+drive..

The diagram for the LT1045 shows it has a single control terminal solenoid. If you want to use a two control terminal solenoid, simply jumper one of the two terminals to the solenoid frame (mower chassis). The other terminal goes to the start circuit (Org/Wht).

If the machine has a two terminal solenoid then it's not a factory configuration. If your replacing a two terminal with a one terminal, connect the start circuit (Org/Wht) to the singe control terminal. The opposite side of the coil is bonded internally to the solenoid frame (mower chassis).

The contactor side of the solenoid does not change. One contact connects to the starter motor and the other contact connects to battery positive and a smaller gauge power feed.

Surging (governor hunting) at idle is usually a fouled carburetor.

Does it not surge when engine is operated at high speed?

If it is governor hunting at both at high and low speed, then either it has a vacuum leak (unlikely) or contaminated fuel especially when fuel has ethanol. Suggest you drain the fuel from tank(s)and the carburetor fuel bowl. Then try a couple gallons of fresh fuel from a station. Don't use what you may have on hand as it too may be contaminated.

If it only hunts at low speed then less likely it is a fuel problem and the carb low speed circuit has a blockage and will need cleaning.

There is also the possibility of a fault in the safety circuit that kills the engine when PTO enabled but with the governor hunting it's likely a carburetor issue.

There are at least two versions of the RTZ-L50.

From your problem description I believe you have an early version with a SPST seat switch. I further believe your test method fails to accurately simulate the failure.

Have the operator sit in the seat and reproduce the failure. While operator remains in the seat, check switch continuity and I believe you will find the seat switch is not open but closed (an operator not present state).

While seat occupied, the safety relay is energized and opens the seat to PTO switch and Brake switch kill circuits.

Check the operation of the safety relay.

With engine off and key in RUN position you should hear the relay click when you sit in the seat (remove your seat switch bypass and reconnect seat switch).

Service the clutch and trans. Haynes or clymer make a shop manual for ur model. Umust do monthly maintenance

STARTER OR THE SOLENOID . THEY BOTH FAIL OVER TIME

Common for parking brake switch to not be depress enough. CK It.

Likely the belt is loose, burnished, or wore out.

Likely it will need to be loosened, but not necessarily removed. Make note of the position of any belt retainers and return to original position when tightened.

Check the carburetor anti afterfire solenoid is functional. Avoid fuel with more than 10% alcohol.

Cooling fins are blocked.

Kohler SV740This is almost always a combustion issue.Check RC12YC plug gap is 0.030"Running on one cylinder? Disconnect a plug wire and start. Reconnect plug wire and disconnect opposing plug wire. Start.If only running on one cylinder and gap and spark are good then check OHV lash.If missing or poor spark on a cylinder... likely ignition module failure.If starter intermittently stalls (makes 1/2 revolution, pauses, continues), valve lash out of tolerance.Fuel - drain carburetor fuel bowl. Capture fuel and check for water.Check battery voltage while engine running. If less than 13V then charging system failure.If you want to test the PTO when on...remove both spark plugs, switch PTO on. Pull deck belt through but you may not have enough leverage on the PTO pulley, Try rotating the fan side (top) of crank by using both hands flat on the fan, push/pull clockwise. Else a 5/8 socket and bar on the clutch bolt (bottom end of crankshaft) will easily turn the crank/clutch.
