I changed the hydro filters and fluid on my jd 6715. when I restarted it I had no steering and bucket would not lift.

my name is ***** ***** ill see what I can do to help you out

a serial # ***** be useful to me if you have one

why did you change filters? was there an issue or just maintance ?

does this unit have power reverser? power quad or syncroplus?

when you stomp down on the clutch the tractor continues to move??

stand by.....

is this mechanical or electronic shift?

FNR lever is it a mechanical linkage to the trans or is that lever an electrical component

ok so to answer your question about fuses it wouldn't have any effect on that system

well..... being that all your levers and linkages are mechanical.....

as long as you can verify that the reverser cable is correctly attached to the transmission I would say you have an internal issue. I don't think its a major one but the issue here is going to be pressures. its very possible that when the hydraulic pressure was off balance for that short time that it stressed or broke a control valve spring. when you push the clutch to the floor it should divert all engagement oil away from any drive packs. the fact that you push down on the clutch and the machine continues to move tells me something in the control valve is not well at all

attached a picture of the screen (#7)

the trans has its own pump. its all a common sump of oil like all the Deere tractors. screen may be a good check but again the clutch circuit is as simple as move the clutch dump the oil. sorry I couldn't give you better news, hate to see you throw valuable time at this. I assume you have changed the trans filter as well?

if you feel that you want to tackle checking pressures I can send you the info. I worked for a deere dealer for 10 years and I have been on these missions before and they can be an in depth diagnostic. just hate to see you throw unneeded parts at this. let me know if you want the info

it may be the cheaper thing in the long run. Again...not affiliated with any dealership anymore...just want to see you back up and going at the best cost and time

what area are you in?

I only ask because I may have a dealer from the old days that I could refer you to
