Hello all. Steve here. New to Green Tractor Talk. I have developed an issue and was wondering if anyone else has had a similar issue or could shed some light as to how I might be able to repair it. I have a Mid 2000's 4310 E-Hydro. This has been a great machine, I use it for everything around the house and neighborhood. Last week I developed an issue. While mowing I noticed while driving the forward momentum became "jerky" like someone tapping the brakes or an air pocket flowing thru a hydro pump. Initially I began to panic... How much is this going to cost!!! Hahaha!!! So I started my research. I have read of a couple people with similar issues with no concrete fixes. Some suggest it is Hydraulic. Change filters, fluids, check screens, etc. Done all that. No change. Read many posts concerning electrical issues. Foot pedal devices out of calibration, frayed wires, dirty connectors, bad control boards, even entire wiring harnesses, which the thought scares me to death. In my situation I believe my issue is electrical. Here is what I have experienced so far.
As above the first time I was mowing, started jerking, got scared and put it away. The next evening, I got the tractor out to see how it would act. When I got it out, all was fine. So I started putting it thru its paces. After approx 30 minutes the jerking returned. I kept using it in hopes to find some evidence. After further use I noticed a code flashing. Short, Long, Long, Short. Also noticed the Cruise Control stopped working. A fellow Deere fan was kind enough to translate the code for me. The MFWD sensor on the left side of the transmission was malfunctioning, setting the code and deactivating the cruise control. To the Dealership I went. Ordered a new LVA17409 (this replaces its previous model LVA11184), replaced it and out I went for another test ride, mowing again. With the tractor cold, I started out with the MFDF in the "on" position. All was well for the first 15 minutes then the Jerking began. No code this time. So I assume the sensor I replaced was malfunctioning. But the jerking was just the same as before. So while mowing I started trying different things. I turned the MFWD switch to the "off" Position... The jerking completely stopped! I turned the MFWD switch on again and the jerking returned. In my mind, I believe the issue I am having is electrical. So I kept mowing with the MFWD switch in the "On" position. After a while I noticed some really strange things. May be coinsidence, but while driving straight forward the jerking is present, turn right the jerking stays the same or maybe even worse. Turn Left and the jerking is evidently less, not perfect but less. In reverse the same but exactly opposite. Turn right the jerking is evidently less, not perfect but less. Turn left the jerking stays the same or maybe worse. So now I am back to square 1, not knowing were to go from here.
This is my story to date. If anyone has any suggestions or things I could try, I certainly would appreciate any help.
Thank you all in advance!!!
