Miande did you ever get this issue fully resolved? If you look at my post history i had the same problem stemming from 2021 when I picked up my 1835m hydro. I suspect it might be either a pedal position sensor or an issue with the electronic dial controls for speed and response. (Two dials near the cruise control button). I have around 170 hrs and have just lived with the problem for now. Like yours the problem usually shows up after the unit is warm.

5 bucks says AGCO will force Massey to discontinue the 1800 series and move on to a whole new line...with same hydrostat transmission from the 1800 and 1700 series. Lmao!!
I have an 1835M with similar problems. If I stop on a downhill slope and try to reverse sometimes there is no movement. Nothing. Neither the forward or reverse pedals will do anything. The dealer is on level ground and can't find anything wrong. Yesterday when headed down a slope, it suddenly acted like it had jumped into neutral and started to roll forward, gaining speed. I hit the brakes and finally got it stopped. Neither forward or reverse pedal would work. Steering was also screwed up. Not sure what to do but I have lost confidence in this machine.

Not sure if yours is related to the previous posts other than being same model tractor. Sounds like a fluid level issue. Might be that going down hill you are not getting fluid into the drive pump?
