Safety Tow Chain
If the mower is towed on a public roadway, a safety chain with tensile strength equal to or greater than the
gross weight of the mower must be connected between the tractor and mower. This will help control the
implement in the event the tongue becomes disconnected from the drawbar. Make sure the chain is attached
to a secure location on the tractor and not to an intermediate support. After connecting both ends of the safety
chain, drive the tractor to the right and left to check for proper chain length. Adjust length as necessary and
allow only enough slack in the chain to make a maximum turn in both directions. When not in use, store the
safety chain to protect it from mud or standing water by wrapping the chain around the tongue. Replace the
safety chain if one or more links or end fittings are broken, stretched or otherwise damaged or deformed.
4.2 Connecting Mower Hydraulic Lines to the Tractor
With the tractor shut down and secured in position, relieve hydraulic pressure from the tractor by moving the
control levers back and forth several times or placing the levers in the float position.
When connecting the mower hydraulic lines, keep hoses, quick couplers, and swivels free of contamination.
Never leave a disconnected hose end open and cap the tractor hydraulic outlet ports when not in use. If the
tractor ports or mower hydraulic hose ends become contaminated, wipe clean with a rag before connecting.
Operating Mower Hydraulics with Three Tractor Hydraulic Ports
Connect one hose into each hydraulic port. Connect lines to correspond with position of hydraulic control
levers.
Operating Mower Hydraulics with Two Tractor Hydraulic Ports
The lines that operate the wings must be plumbed together and will be controlled using one hydraulic control
valve and the center section with the remaining control valve. Ensure that the operator is aware that each wing
cannot be controlled independently nor will they raise and lower simultaneously.
