Question about Swisher 60" 26 Hp Zero Turn Radius Riding Mower #Zt2660b

1 Answer

Electric clutch wont engage when when switched on even though I can hear a clicking sound at the clutch.

Belt to deck is good. Blades seem to freely turn manually. Sometimes tapping clutch prior to switching blades on seems to free it up momentarily but it will not stay on and the blades do not engage. I think my clutch is just bad. Is it hard to replace?

PTO Clutch will not stay engaged.
There is a very fine one page discussion on evaluating electric clutches at this site:

http://www.messicks.com/Articles/FixingElectricClutch.aspx

My JD tech manual, which covers the entire LA 100 series, agrees with the electrical specifications. It states that the Electric PTO Clutch should show the following:

  • Resistance 3.7 ohms
  • Current Draw 3.25 amps.
It does not give the air gap. It does include a note to check the PTO Clutch Key for damage or if missing. So there is a drive key between the PTO Clutch and the shaft. Additionally, it recommends checking the tightness of the cap screw. That's the screw or bolt that holds the clutch on the shaft.
  • Cap Screw torque 55 lb-ft (75 N.m).

Blades won't engage. I hit something, blades quit turning, check belt, its okay. When you hit button to engage blades, you hear click


When you look under the mower do you see two belts ? Top one goes to the rear axle and lower one goes to mower deck spindle.
Your description sounds like the electric clutch is engaging,so if you are seeing two belts coming off the bottom of the engine maybe the belt bounced off a idler pulley on the deck and is not tight enough.

THE BLADE DOES NOT ENGAGE WHEN I PULL OUT THE KNOB THAT IS SUPPOSE TO ENGAGE THE MOWER BLADE


"I have an Electric Clutch and my Blades will not engage when I operate the PTO switch."
  • Turn the engine off and remove the key.
  • Check for physical damage; anything look bent?
  • Is the deck belt intact?
  • Spin the pulley on the bottom of the clutch. Does it spin freely?
  • There could be mud or grit stuck in the clutch.
  • There is a drive key between the clutch and the shaft. Has this key been sheared?
  • When you pull the PTO switch does the clutch make a "click"?
When you sit in the seat and turn the key, one click from off to run, you will hear a faint click. That faint click is the fuel shut off valve under the carburetor. It is turning on and off when you cycle the key from off to run. Do not confuse this click with the clutch click.

Leave the Key in the Run position, cycle your PTO Switch on and off. You will hear a click. This click will be twice as loud as the fuel switch click. This louder click is the Clutch engaging. If you do not hear this click, the PTO switch may be bad or the Clutch may be bad. This is assuming your battery is good and fully charged and that your Key Switch is functioning correctly.

Why won't the blades engage on my Ariens 911403


Chances are the deck drive belt has been knocked off one of the pulleys or the drive clutch won't engage properly. With the spark plug wire removed, rotate the blades by hand and make sure they both move together. This verifies the blade linking belt is OK. Now engage the blade operating control and feel for resistance as you rotate the blades. If you feel no change in resistance, remove the belt cover and reinstall the drive belt over the pulleys and tensioner/clutch mechanism.

I have a cub cadet RZT 54 that was purchased in the spring of 2009. The mower cranks and runs fine but the blades will not engage. Have looked at electrical connections and everything looks fine.


Do you hear a "clunk" when you engage the PTO switch, but the blades don't turn? If so, then check the mower deck belt - is it properly threaded, and tensioned by the idler pulley? If there's absolutely no sound when you engage the PTO switch, the problem is likely electrical (even though everything looks OK). The PTO switch, PTO clutch, and the reverse lockout switches (near the bottom of the fwd/reverse control arms) should be checked. I don't think there's a separate fuse for the PTO on your mower, but there may be a relay. Even though these parts and connections look OK, they can fail internally. Best bet is to get a multitester and check each of them with the ohmmeter function.

Turn off mower blades the electric clutch spins and the two green


There should be a metal "anchor" that bolts to the chassis or engine. It has a rod that sticks downward, fitting into a notch in the clutch to keep it from turning. It must be missing or broken, or maybe the clutch is the wrong model, and that's why the clutch itself spins and rips out the wires. Good luck! Please rate if you found this helpful, thanks!

My blades wont engage and just hear click sound?


No permanent solution, but you probably can get by once by "riding" the clutch engagement lever - pushing it only part way forward and holding onto it.

Pto willl not engage


Hi mate, Although my trade is repairing turfcare machinery, I have no experience with this model, so I will try my best. Firstly, the clicking you hear will probably be the electric clutch engaging/dissengaging. Firstly, see if you can get the clicking with engine off, keyswitch in first position/on/lights on dash. You may have to place something heavy on the seat and have traction pedal in neutral. MAKE SURE YOU DO NOT ENGAGE THE STARTER MOTOR/START THE ENGINE THROUGHT THIS!

Now have a look under the footwell on top of the deck and try to determine where the clicking is coming from, there will be a clutch there somewhere joining the engine drive pulley to a deck pulley, Also at this point check that both belts are on and with the ENGINE OFF! spin the blade/blades with your hand and ensure that the deck belts are not slipping on the deck pulleys. If they are you will need to establish where the tensioning system is. (Sorry i know pretty vague)

Back to the Clutch, once you establish where it is, engage the blades ENGINE OFF! and you should feel a greater resistance turning the blades as you are now turning the engine as well, beware though, it is theoretically possible to start the engine by doing this, but you will almost certainly not be able to spin the blades that quickly by hand.

If it is clicking to engage but not turning the engine pulley when spinning the blades by hand, then try tapping the clutch lightly as it may not be fully dissengaging.

I would put money on it being either one of the belts coming off/snapping, the blades jamming or the clutch not engaging fully.

If you find that the clicking is not the clutch engaging and its actually getting no power to the clutch then you need to go back to the pto switch and go through all safety switches! (good luck, it usually ends up with me bypassing them or running a new cable to the switch,then, smoke, shouting, swearing etc etc!) Either not advisable.

In doing all this you should have been able to have determined the problem be it one that I have mentioned or another.

Hope this helps,
Chris.
