rear hydraulics going wonky

[PatriotOutdoors]

so i am pretty sure I left the rear implement in the up position last time I parked the tractor for a week or so. when I got in today I found the lever for 3pt lift all the way forward (which I never do). so I thought that was strange. but I started it up. and immediately found the 3pt lift to shudder when moving both up and down. not every time and definitely depends on how youre working the lever but I've never seen it do what it's doing now. it'll jerk while moving into position.. before it would only jerk it I rapidly moved brush hog upwards.

this is a KIOTI ns4710hst
it has 11 hours on it.

anyone have any ideas? I'm hoping it'll be normal tomorrow.... lol

Check your fluid level.
Make sure you do not have the draft control on.

Might need a filter change - start with the simple easy stuff first

Why would you leave the tractor with the 3pt up? You prob just have air in the system so cycling it should help.
