LEFT SIDE CONNECTION
Connect the 'Hog to the LEFT side Lower Link first. Use three point hitch hydraulics to set 'Hog connection level with left Lower Link eye, or just a tad lower. You can lift the Lower Links a bit manually to get the 'Hog connection point onto the left Lower Link eye. Secure connection with a lynch pin.
(LEFT side is
without manual up/down adjustability via the three point hitch Lifting Rod on the right side.)
RIGHT SIDE CONNECTION
To connect RIGHT Lower Link, adjust RIGHT Lower Link up/down via manual
Lifting Rod on RIGHT side of three point hitch. Hopefully, after making this adjustment the right side of the 'Hog will connect to the right Lower Link eye.
If it is off just an infuriating smidge, connect the Top Link and adjust the Top Link in/out a small amount and that will usually tilt the 'Hog enough to allow the right side of the 'Hog to connect to the RIGHT Lower Link eye.
Secure connection with a lynch pin.
Lift the connected 'Hog with three point hitch hydraulics about 6" and snug your sway stabilizers.
KEY: The LEFT Lower Link can only be adjusted up/down via three point hitch hydraulics.
The only
manual adjustment of the Lower Links is to the individual RIGHT Lower Link, via the manual Lifting Rod.
For virtually all implements the connection sequence is left, right, top, PTO.
Connecting implements is mostly technique. You will acquire the technique over time.
If you make a similar post in the future tell us what tractor is involved and what brand of Rotary Cutter. We can provide better tailored directions. Use standard tractor nomenclature from your Operator's Manual or you introduce confusion. (Not Lift Arms; Lower Links)
