Question about Mustang Rzt 50" Zero Turn Riding Lawn Mower

2 Answers

The mower deck on our Cub Cadet RZT 50 mower stopped working while mowing. We have cycled the PTO switch several times with no change. The belt is in place and the mower blades rotate freely by hand. The wiring appears to be plugged in on both ends with no problems that I can see. We have owned this mower for 4 or 5 years with no issues.

    Does the PTO engage at all? All of these models are equipped with a seat safety switch that has to have a open circuit to run. The PTO Clutches do go bad...first check the wiring from the clutch to make sure they are connected and not broken....you maybe looking at a new clutch that can be upwards of $400.00. www.nnyparts.com

    No the PTO does not engage at all. I tried a new battery and that had no effect. The seat switch does stop the engine if it is not put in park so I don't think that is the issue. I have checked the wiring that I can get to without disasembling anything and I could find no loose plugs or cracked/broken wires. It is either the PTO switch or the clutch. I am not looking forward to a $250.00 to $400.00 repair bill, on the other hand it has been 5 years of trouble free no expense other than oil and filter changes mowing. So I am probably due for some up keep.

    I had an issue with my Cub Cadet RZT54 with the blades disengaging and I was unable to get the PTO with to work. What I found with my case was that there's a switch at the base of each steering handle that disengages the blades/deck when you put the levers in reverse. It appears that one of my switches got stuck in, making the mower think that it was still in reverse. I was able to spray the push button switches with some WD40 and it's been okay since then. I hope this helps.

You can check the clutch by taking a wire from the ground and a wire from the positive side of the battery and energizing the clutch directly with the belt off to see if thats it. It could simply be a wire loose in the connection on the clutch....their soldered on.

My RZT 50 turns blades on when levers are pulled back instead of shutting of and shuts off when in forward position ? could it be a switch is bad if yes what switch?


Sounds like someone has been working on the wiring, probably trying to bypass the reverse cut out switches . If you follow your steer control lever down under the plastic console covers there will be a switch, one on each steer lever by where it hinges. I don't think the switch is bad because it would not work at all if it was.It is like a door bell switch, when you pull back on the steer control lever it pushes it in and disconects the circuit to the PTO switch and the blades quit until you push them forwards and lets the curent through again. Also check the push pull PTO switch .Every safety switch on the tractor will meet at that switch and plug into it, . That model cub RZT50 has to have the worst switches ever made, but they are available and cheap on ebay. Plunger Switch 430362 430 362 for Cub Cadet Troy Bilt MTD 700 Series 725...

New pto switch stoped working after 4 mowings


Maybe the problem wasn't the PTO switch. My Cub Cadet RZT PTO would disengage when I backed up and then failed to re-engage. I was able to isolate my problem to the safety switches at the base of the steering levers. I sprayed them with WD40 and they've been fine. Just a thought and worth checking. I hope this helps.

Pto blows the fuse everytime i engage it on my rzt 50 cub cadet mower.


Wire harness for the PTO on the RZT's is designed dangerously near the drive pulley. After time, the harness drops and comes in contact with the pulley which grinds through the coating and shorts out the circuit. Repair (tape up) the wiring, relocate the the wire to the opposite side of the crank pulley (may have to zip-tie in place) - shouldn't be a problem anymore.
