Hydraulic lift question
 

Should the cylinder have some fine adjust to lift and lower or just full lift and full drop. Sorry used to hydraulics on a farm tractor. Any adjustments I can make? Really jumpy control hard to do small increment lift while running scrape blade. Jumps way up immediately.

Assuming you are talking about your 1650, there is an optional lock out pin for the lift assembly that gets installed to more or less cancel the built in float to prevent scalping when mowing over uneven ground. Part #9

Or you could add some weight to the blade proper.
