If your battery is old or low then it may not have the power to run the PTO. It also depend on the size of the object that you are trying to operate off of the PTO shaft and if your engine can take it. Only the rear PTO is live or uses generated electricity. The front one is independent so it probably runs off the battery.

SOURCE: I have a JD 1070 4 wh dr, when running a brush hog

Reading on line, I see your tractor has a PTO clutch. It must be slipping. It either needs adjusted or replaced. A slipping clutch disc will make a bad smell.

SOURCE: JD 6400 tractor, PTO light flashes when engaged

The most likely problem is the pto solenoid valve on the rear of the tractor.It could be the speed sensor but you won't know until you get the codes read by the dealer.I have had to replace the b.c.u. for this problem but it is not common.

SOURCE: JD 420 PTO works fine when cold/newly started.

I used a neighbors 420 while mowing and there were times that I tried to restart the blades after turning them off for a bit. I found, I think, that you had to have the brake depressed to make them turn back on.

SOURCE: the battery is not charging.

Under dash on left side you will see the regulator tucked behind frame. Once located unplug white connector and check the Brown wire for any damage in or around connector. These will tend to melt or turn the area around the Brown wire black do to poor connection. If everything looks good there then replace regulator.

Everything works fine until I engage the PTO for the mower deck. The battery discharge light comes on and eventually the battery goes dead.

The PTO clutch is an electro magnet. There is probably a dead short within the clutch body. Replace the Clutch.

JD X595 4x4 mower - Starts OK, BUT, as soon as the brake is released, the motor cuts out.

I would try bypassing the seat switch and the brake switch. Do this one at a time to determine if the switch is bad. Also buy some Sta-bil fuel stabilizer and gel remover. I recommend this for any seasonal equipment. Often the engine is not getting enough fuel and will stall when the pto is engaged. Sta-bil often rectifies this problem.

Why does the pto on my not turn on?

Electric clutch may not be getting enough power. Check fuse. It may be getting power that is not sufficent from low battery. Check water level in battery, check power by turning lights on and cranking motor. If lights go very low then battery is suspect. If my JD battery gets very low it has to be charged with external charger as the JD charger cannot bring very low battery up and drive clutch too.

My 96 pajero will not start at times

did you try to jumper cable start car?
that is a NO CRANK issue, no car starts (cept mine, its an M.T) with out the starter motor working, (mine can be push started or hill started)
Jumpers fix issue?, so bad/dead /discharged battery.
so is the IMMO light showing IMMO blocking, , you ever read the operators guide and see IMMO rules>
lamp on, lamp off, lamp flashing... all have meanings.
the IMMO cuts fuel, not the starter,
so its not IMMO. Its a bad starter system. (it is a system of parts)

no crank has many causes. the tests are easy with a voltmeter.
a $20 volt meter can save you the cost of a $140 battery.

It can be a free fix. (clean the battery lugs yet>?) ask how.
to start the engines (assume engine is ok and EFI ok, and spark ok)
the start system can fail like this.

1: A dead battery ,bad bat., or only discharged, a voltmeter solves this riddle. (ask how)
if only discharged, then charge it. and find cause of discharge ,1st or it will repeat.
the order here, counts.
2: bad battery to starter cables.
3: bad starter solenoid, or starter. we hot wire IT.(ask)

(fails? , bad starter,assumes battery side is good,first)
hot wire fails.
I hit the starter casing with a hammer bam, it now works.

4: starter cranks hot wired. it's good. (test passes so i then find the bad KEY line. cause,,, we now have problem cut in half.

5: the KEY line is that wire that runs from KEY (ST) to the starter , small wire.
on an A/.T car, (auto/trans) car, the key line passes thru the
PRNDL switch on tranny. so wiggle the gear shift. cranks now>?
try cranking in Neutral. some cars allow this, and
the Neutral side of the switch will like new, and car cranks.

that was the long answer.
here is the short.
Take it in. call the auto club.
guess, i guess,?
1: left head lights on.
2: battery lugs never cleaned.
3: battery died.

I have an older yardpro riding lawnmower with a 18hp kolher when i turn the deck on it starts to discharge & will kill the battery eventally, if i shut the deck off it will charge, looking for ideas to...

Faulty voltage regulator. Insufficiant output to operate the PTO clutch and charge the battery.

If the battery charges without the PTO clutch 'IN', then this proves all the wiring, so this has to be the answer.

I suppose there is a remote possibility that the holding coil in the clutch is partially shorted, but it's unlikely.

Mower will barely turn over. new starter and batt.

not 100% but i have a JD 345 that i just went through the same scenario with, turns out the pto cluch was froze up, take the clutch off (can be a pain, medium size gear puller a plus) and see if it turns over. new clutches are a lot less expensive than a new mower!
