I have a 2017 john deere 323e ser 1t0323ebjhj322260.The problem is when you lower the bucket solwly it works correctly mash the pedal any farther it lowers very fast.I checked all the linkage and found no problems,Is there and adjustment for the speed it works at.The curl has no issues.
Are you sure you aren’t mashing it into the float position?
Sorry i didnt state when this happens its real fast next thing you know the machines front is lifted into the air.
