JD 455 PTO question

[lonewolf5413]

We own a mid 90's model 455 which has been a great machine however this past week the front PTO failed to operate and the PTO light for the front ( mower deck ) pto did not come on when the switch was raised in the on position. The rear PTO was on and working. However, this evening while I was poking around trying to figure things out I noticed that the rear PTO light does not come on nor does the PTO spin.

I assume this is an electrically related problem and am just trying to fighure out where to start first.......any help is apprrciated.

WELCOME to LMF...

Is the 455 Rear PTO not an Independent hydraulic clutch PTO? :smile:KennyV

If you mean similar to a farm tractor where you must engage the PTO....the answer is no. Both PTO's are triggered by a switch on the instrument panel. You pull up to engage and push in to disengage. Three days ago I had the rear PTO still coming on but after unplugging the switch, checking wires etc.. it does not come on now. ( I did not leave anything open....basicaly one switch and tracing wires).

That is why i assume it is an electrical issue such as a circuit board, wire, switch something along those lines.

There is a hydraulic clutch pack in the transaxle...
A solenoid on top towards the rear, Metal thing with a plastic nut and one wire on it... Check that wire for 12 volts when you have the PTO on (with someone in the seat)....
