SOURCE: Electric Clutch want engage the mower deck on my l120 john deere

They wear out. How old is the mower? Mine just gave out this week in the peak of hay season. (my grass) The wire can be unhooked from the PTO clutch and a 12 volt jumper can test it, if it jumps, it is good, if not, it is shorted out, they are expensive, I found 3 of them all the wrong size for mine. Try to find the same one. Ebay has a couple on there right now. Check it out.

SOURCE: Eletric PTO is not working

The PTO draws a pretty good current, so a weak or loose contact in the switch, or in the connections on the back of the switch, could cause this overheating. But it could also happen if the PTO clutch itself or the wiring to it has a short. If the mower's still under warranty, get the dealer to diagnose and fix it. If not, then I'd measure the resistance of the PTO clutch - should be about 2 ohms - and make sure the wiring to it isn't shorted. If all that is OK, then just replace the PTO switch and any melted connectors and wiring. Good luck!

Park brake switch is the most likely culprit,any other would cause the tractor to not turn over in the crank position.

F525. Updated mower switch by John Deere is not engaging mower


The John Deere F525, a front cutting machine, has 3 fuses.
20 Amp
15 Amp
10 Amp

Check the 15 amp fuse. I believe this supports the PTO clutch. If you replace the fuse and it blows again, check the electric clutch. You will likely find burnt or melted wires. The bearings do go out on these clutches causing them to run hot and eventually burn up.

PTO Clutch will not engage: 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).

If the fuse blows, I recommend you check the resistance of the clutch. If the clutch is shorting to ground it will show zero resistance when you ohms the connector wire to a ground position. In which case, you will have to replace the clutch.

Fixing Electric Clutches

Other possibilities.
On the F525 there is a cut-off switch in the hydraulic system. It is a low pressure cut off. If you were running the mower and deck and then it suddenly stopped, it may be low pressure in the hydraulics. It will not automatically reset as you are using the same volume for the drive pumps. Once the oil gets low enough it cuts out the deck drive 1st, then the drive pumps.

Why mower blades will not engage when buttom is pulled


I believe this one has an electric clutch. Check to see that the switch is operating properly, that the wiring is good to the clutch, and that the clutch is good. Use a volt meter to check that there is voltage to the clutch when the switch is operated.

Mower blades will not engage on my STX38


Turn the key switch to the on position. Pull the blade engagement switch on.Look under the engine and find the electric clutch. Disconnect the wire connection there and while using an ohm meter, check and see if there is 12 volts on one of the wires. If so, then the clutch may be your problem. If not, then you need to trace back the wire from the clutch connection and find out why there is no voltage

Hi, check that you have 12 volts to the pto when the switch is on. It sounds like your pto is fried as the switch is functioning correctly. Regards Phil.

Mower will not engage when switch for electric electric clutch is pulled up into on position


could be safety switches faulty or sticking,usally 1 under seat, and 1 by the catcher, pto toggle switch maybe faulty, if battery is low there won't be enough power for the clutch to engage. I would jump the clutch to make sure that hasn't died first cause that is the costly part.

I have a John Deere l130 and the mower blades engage when I start the engine even when the PTO switch is off. Any suggestions?


sounds like you have feed going directly from switch as soon as you turn ingition to start mode ?

check wiring back from electric clutch to main switch

possible 2 wires have been placed on main switch instead of pto switch ?

or you have a crossed circuit somewhere (that is feed from another live circuit) not directly connected and its ended up at electric clutch as soon as you liven main circuit


a wiring diagram may help

check with www.johndeere.com
or www.jdparts and enter their site load your model and type
and go to electrical system and print out a copy of wiring diagarm

you may need to supply and user name and apply for password from john deere via their site apply on line

its a good site for info and parts diagrams


cheers hope it helps

Pto spis all the time on my 1989 john deere 420


Are the blades turning? If they are not, this is normal. The PTO is an electro magnetic clutch that engages when you apply electricity via the PTO switch. When it is disengaged, the bearings and top portion of the clutch will turn because it is coupled to the engine. If the blades ARE turning then you have a bad clutch and will need to repair or replace it
