Before You Start
Review these instructions, and make sure you
understand which existing system components are re-
used, and where they are located. The new components,
and the existing components to be re-used or discarded,
are located on the tongue of the drill, near the hitch.
Inventory the contents per “New Parts: Kit 194-122A”
on page 9.
Tools Required
• basic hand tools
• a tractor with two hydraulic circuits and suitable hitch
• liquid thread sealant
(for NPT fittings only - do not use PTFE tape)
• buckets for recovery of hydraulic oil from open hoses
These instructions presume a drill that has seen some
use, and may have pressure in the hydraulic system. The
installation may be done with the drill folded or unfolded.
Pre-Assembly Preparation
Inspect the Mounting Site
Refer to Figure 2
1. Examine the mounting site on the tongue. See if a
valve is already on the valve mount , and if any
hoses are under the clamps just aft of the mount.
2. Make sure the clamp hardware ( or ) is present.
It may be one of two different styles, depending on
the drill vintage. If there are no hoses under the
clamp, remove and save any: bolts, lock washers,
flat washers, clamp hold-downs, clamps and hose
guards.
If the drill does not have markers installed, a valve
mount welded on the tongue is available. The Two-
Outlet selector valve mounts there, and includes a
bracket to provide a second mount point for another
valve.
If the drill already has markers installed, the valve mount
welded on the tongue already will already have a valve
mounted on it. You can mount the Two-Outlet selector
valve above it, or exchange their positions, using the
bracket in this kit.
Negative Tongue Weight Hazard:
If unfolded, the drill must be hitched to a tractor during
Opener Lift, to avoid negative tongue weight. Hitch loads can
range between +4000 pounds (folded) and -1000 pounds
(unfolded), depending on drill model and configuration.
