Dyna 4 problem

[Floordoor]

Down the road today in top gear all was fine, noticed on the dyna shift screen number 2 was lit up and number 1 was flashing. Pulled up at gateway, went to move off and tractor would not move. Any ideas what that number sequence means? Cheers.

You need to count the number of flashes to give the sequence. What model? I'll guess it is the Bottom of Clutch switch on a 5455?

A model would help, I’m not convinced it would be BOC switch that cones up as a orange diamond on 6200 series but I haven’t a lot of experience of dyna 4 but would be surprised if it didn’t have a similar indication of BOC switch problems.

 

[Floordoor]

Yes it’s a 5455. Left it switched off for half an hour went back and it was all fine worked all day no bother.

Did you go down a range before it stopped moving? Or just dip the clutch ?

Can’t remember exactly probably went down a range.

Mine is a snoopy nose one and does exactly the same but only after road work.... looked up the code in my old training notes and it was a discrepancy between range signal - basically the 4 range switches couldn’t agree what range it was in..... changed the range switches and was no better ..... got a solenoid to try now but not got round to swapping them yet

It will be either a range solenoid or more likely a range switch, and most likely the bottom left switch
If you change the switch make sure there is a sealer washer fitted, as without it it sticks to far in and is permanently pressed

Tractor wouldn’t move from start up this morning, again number 2 lit up and number 1 flashing twice then a pause then 5 times then a pause then really fast a few times.

Try the range switches
Just swap them about, fault code will alter if you move a dodgy switch to another position
If not swap the solenoids over again fault code will alter if you move the dodgy one.
