Not even using the 3 pt. hitch. Dealer said to replace sensor, we did but light is still flashing. Talked to dealer today. doesn't know what is wrong. Didn't think it would hurt tractor. But why does it flash, if it shouldn't be.

I would suggest you find a JD dealer and buy a manual if you want to do the maintenance yourself. You can also do a Google search and find manuals.
I would also suggest you completely drain the old hydraulic fluid and replace it with new fluid and a new filter if it has not been serviced any time in the recent past.
The symptoms you describe can be low fluid and/or a clogged filter. If you or anyone else has run the tractor too long and it has low fluids and/or a clogged filter, you can damage the hydraulic pump and that can get costly.

We will be testing for voltage to the points, coil, engine to tractor wiring harness, ignition switch
Tools needed:
volt meter to read 12 volts, or test light
1) with the points open: is there voltage at the connection wire at the points
If yes; adjust points to .020" and try to crank engine and check for spark
*** you may want to determine if condensor is connected to this wire also
if no
2) check point side (neg or - ) of coil for voltage
if yes, engine should start
if no
3) check for voltage at the + side of coil
If yes, coil is bad
if no
4) check wire connector from engine to frame wiring harness
if yes; engine should start
if no
5) check wiring on the back of ignition switch
if yes; engine should start
if no
6) check that ignition switch RED or BATTERY supply wire has voltage
if yes; switch is bad
if no
7) check supply wire and circuit breaker connected to the battery side of the solenoid
if yes; engine should start
if no; circuit breaker could be at fault or wire connector at battery supply

SOURCE: I have a john deere 6400 that wont start from cold
i had the same problem, it is most likely that your fuel lines are leaking and fuel pump in tank is weak
when the tractor sits for a while the fuel drains back into the tank, thus your injection pump has no fuel in it.i solved it by replacing all the lines and i added electric fuel pump on outside of tank and connected the power to key,when i start the tractor i turn key on for a minuet or so than start the engine ,it solved the problem.
