JD 4400 Tractor won't start

[doc2460]

Ravensroost,

I have a PTO lever on the right side of the seat. I've pulled, pushed, jiggled, cussed and it still won't start.

Here is the wiring bundle for location of neutral tran switch.
The F5 fuse is with the other fuses on the fuse and relay board (previous pic posted). When I find the PTO sw, I'll post

Here is the main wire bundle showing the rear PTO switch relative to the park brake switch.

Here is an image showing the neutral switch (46) bolted to the speed control lever (why?, I don't know).

One more, as this shows that speed control lever and the likelihood that the neutral switch is attached to this (although it is not shown in the diagram). Maybe a visual inspection of this (if possible) will be a clue to a "no start" if the pedals are not in neutral position. Guess one could turn on the key and work the forward and reverse pedals to see if a neutral position can be found. But that sounds to easy.

The PTO mechanism is a huge problem with these tractors. The switch is
on the central gearcase on the upper left side. You need to get in there
and put a jumper on the connector, after pulling it off.

As for the neutral switch, if that is causing a problem, then you need to
put a jumper on the "X2" connector under the left side of the floor board,
as shown in BEENTHERE's diagram.

I have permanently jumpered both of mine.

And...another pic showing the actual neutral control switch. Seems getting at it might mean splitting the tractor.... But maybe not.

Still looking for the PTO rear switch, and am thinking it is on the right side of the tranny, just under the forward/reverse pedals. But no pic to confirm that yet.

If you have a hydro tractor, verify your pedels are not activated - Meaning both are in the stop position.

Hey all,

Just an update. JD was able to get to my tractor sooner than thought. Turned out to be the rear PTO switch. Mechanic said it was a bear to get to...had to pull one of the rear tires and the fender to get to it.

Anyway, it's up and running now. I appreciate everyone's help.

Glad to hear it's running again.:thumbsup:
