    X738 mower deck lift and lower problem

    I bought a 2016 x738 last fall and used the mower once last fall before taking the deck off to install the snow blade. After removing the snow blade and installing the mower deck I started to mow last weekend. I noticed raising and lowering the mower deck works intermittent. If it stops working I stand on the mower deck while raising and lowering to get it working again. I'm wondering if it is low on hydraulic oil? Is there a way to check the oil level?
    It only has 5 hours on the tractor.

    You check the hydro oil with the screw out dip stick under the seat.

    No owners manual?

    Did you completely open the bypass valve when you took the blade off & put the mower deck back on? The valve is behind the quick connectors on the tractor.

    The dip stick to check the transmission fluid level is under the front of the seat suspension. Check the fluid level when it is cool. Slide the seat all of the way back. Clean dirt off of the dip stick. Unscrew the dipstick. Wipe fluid off it. Reinsert the dipstick back in the tube. Just let the threaded part set on top of the tube. remove the dipstick & read the fluid level. Add fluid if it is low.

    If you used it for snowblowing the valve thing is likely your problem.

    Hy-Gard is cheap compared to drive train repairs caused by inferior oils that may not meet specs.
    I have more ideas than ambition.

    Yes, the valve is open all the way. The oil level reads low on the dip stick. It shows 3mm on the bottom of the dip stick. I know I lost some oil when removing the snow blade since some of the oil stayed in the snow blade lines and cylinders.
    I guess I will make a trip to the JD dealer for some hy-gard.
