So how far apart are you guys setting these adjustable stops?
As it was mentioned before there is now proper distance for all of us. Just a proper distance for the individual owner's preference.
Pull the 3pt lever back very slowly and when the hitch moves at the speed you desire mark the spot and set the stop there. I should also mention that the selected point will work different when the tractor (hydro fluid) is cold or warm. When the whole machine warms up to normal operating temperature the hitch will raise faster at the same set point where it was painfully slow before operating temperature is reached. Later the position of the stops can be fine tuned to your liking.
