just sprayed wires from fuse panel,was all caked with dry mud,cleaned all out followed wire back from seat down top of back diff ,3 wires come out of the back differential that join and head back up to fuse panel and then to front battery!! so I tried starting tractor no probs,no error 15 till I hit forward/reverse pedals it came on right away,then pulled out pto switch and killed engine.So back at it tomorrow for further involvement after I go for my air/oil filters /oil at local JD dealership in SOO,MICHIGAN and have a chat with their head JD mechanic as well!hoping its just a bad wire or connection.like you say its all electronic.Its just funny how it happened,just pulled in my neighbours yard and then it would not move after moving snow and driving down the road?has to be a bad wire like you say.Here I thought because I was low on oil in the back differential cause it all runs on oil pressure also.

Make sure reverse pedal not partially stuck down same with forward

they never are Dusty,almost like hydraulic steel pedals have to force them down with foot pressure for forward and reverse,and that's when I get the code error 15 ,no movement at all,asking you could have I damaged anything with the fluid being so low in back differential?when theres no fluid it wont move=no fluid pressure right?

How low was the fluid, how much did you have to add to top it off?

I had this very same issue on a 4410. No forward or reverse and the engine would die when the pto switch was engaged. It was the plug for the seat switch. It had been jammed in somewhere I don't remember exactly the whole picture but once I straightened out the plug and made sure all the wires were pushed in the issue went away.

wow reallys??just finished unplugging the seatplug and cleaned it out lubed it,mine has to be the wiring like dusty says once I trace it all back where they all go ,something is shorting out with the pto load when turned on,and no forward or reverse either asd well.

guzzman, how much fluid did you have to add?

 

[guzzman007]

2-3 gallons

Dusty still having issues ,turn key on and error 15 comes up when I push down on forward/reverse pedals,and when I push both down code 1 comes up?so I jacked one side up to bleed the air out as well with rear diff fluid cap off,been under tractor all afternoon,theres a plastic cover under the f/r pedals and is all full of crap dry mud ,just cant seem to get the plugs out to get the cover off,its gotta be the problem in there,where the wires run to,so I sprade a cleaner/lube in the hole where I can see the wires from foot pedals.any thoughts
