Thanks for taking the time to do these videos. I know it's time-consuming, and it takes time away from other things you could be doing, so again, thank you.

Thank you so much! I thought maybe I needed to get a new battery... I mean I'm using a jumpstart to get it going...I know, I know.... Never thought the battery was used for more than starting it. I'm so ignorant when it comes to mechanical devices. So glad we have people like yourself to help us

I had same problem with a Toro Time cutter and I unplugged it and sprayed it with WD40 and it worked. I sprayed it switch button and the connector and all the bears and it worked.

My blades simply slow down in mildly thick grass. Then come right back up. The belts are tight. The mandrels snd pulleys are smooth. Is it likely that the clutch is slipping under load and i should just get a new one? I alread set the gap.

My exmark with 1018hrs is when I first start mowing pto disengages 2 or 3 times push pto switch down pull back up blades come back on and mow 2 to 3 hours and it never happens again, dealer checked battery and said battery is good, so not sure but will try some of these trouble shooting suggestions learned in this video, thank you

@stressmasterbk4294 7 ай бұрын

try adjusting the pto so the gap is smaller between 0.010-0.014 is the most common gapping but look it up for your model

@jdstang89 5 ай бұрын

Great video, getting a new battery tomorrow to hopefully resolve my blades randomly disengaging. If not I’ll follow this like a manual and get a new clutch if it comes to that. Thanks!

I'd recommend checking your mowers charging system is working properly. If your a PTO that is engaged via a switch then it draws power from the battery and if the charging system isn't charging the battery, the pto clutch/ blades will shut off first as the battery gets too weak. Here is a video I did explaining how to check your charging system. kzbin.info/www/bejne/jpuUqGuajN2Upqs

I have a Cub Cadet RZT-S which is a zero turn w/ the steering wheel. I just had an issue where I had to realign my front wheels because one was pointing outward. After I finished making that adjustment, now my mower works fine, turns fine, blades engage, etc. BUT if I turn the steering wheel to the left the blades disengage. It runs fine going straight or if I turn right but I can't turn left of they disengage. Does this sound like a wire is getting pinched or pulled when I turn left or could it be something else. It disengages almost immediately with the slightest wheel turn to the left. Thanks for any help.

Got a cub cadet RZTL. Blades keep shutting off. Replaced the pto switch and clutch, battery is good and motor shows to be charging. Zip tied the "seat switch" and the clutch still disengages. Motor never dies. Do you have any idea what im dealing with??

@Mechanical_Mind 3 ай бұрын

I would carefully inspect the wiring harness for loose or worn connections and/or damaged wires. Check continuity of the harness with a multimeter. You can also use a test light and the clutch and wiggle and shake the harness anywhere you can. That will help find the trouble area. If that's all good next, I'd look at the relays. Some models have all kinda of weird issues that start happening when water gets into the ignition switch. Keep in mind that just because you have the seat safety switch (aka operator presence switch), zip tied doesn't eliminate it from being the problem. Switches like that often work intermittently before they stop working completely.

When my blades are engaged, I can’t tell if the engine wants to shut off or just the clutch but one of those, wants to shut down but then catches itself and goes back to normal, it keeps doing that randomly throughout the day. Any suggestions why?

What if you have a turf tracer.. on steep hills slanted 1 way the blades turf off constantly I turn around and go the other way. It works perfect any ideas

@Mechanical_Mind 9 ай бұрын

My guess would be that the seat safety switch / operator presence switch might not be fully engaged when you're slanted one way. My next thing I would check would be the wiring harness for the pto clutch

My blades quit working on my gravely in middle of mowing. We replaced our battery with a normal riding mower battery. Mowed fine for a whole mow then 2nd mow was mowing high grass and it stopped out of nowhere. When I engage pto I hear a click but blades don't spin. Any advice?

@Mechanical_Mind 7 ай бұрын

I would check the charging system. Those clutch require a constant draw on the battery while engaged. When the charging system doesn't keep the battery charged up enough, the clutch is the first thing that stops working. kzbin.info/www/bejne/jpuUqGuajN2Upqs

@Mechanical_Mind I was mowing. Had to disengage blades to move something in the yard. When I got back on the mower and pulled the knob to engage blades nothing. I drove it back up to the house, and shut it down. Now when I go to try to start it nothing at all as if it's stuck in engage mode without blades moving. Anyone help?

@DavidWeinberg-cm9xd Жыл бұрын

The clutches can get weak when in use, and just disengage the blades? The electromagnetic clutch is using a coil basically, to force the clutch to engage and disengage? Coils can become weak and fail, usually when warm, or under extended use, more so than cold? The clutch mechanism can also become worn and sloppy, creating more room for debris and dirt to hang it up, or bind? The switches will go bad on occasion, but the switch is only doing the low amperage side of the circuit? The switch controls the PTO relay to do the higher amperage control? If the low amp switch did the On/Off operation of the PTO, it would burn up pretty quick?

@Mechanical_Mind 7 ай бұрын

No, it would not hurt it unless the pto was constantly going off and on from voltage dropping too low
