Prepare New Hitch Hoses
Two circuits (Transport Lift and Opener Lift), which were
intended for direct connection to tractor remote ports, are
reconnected to the new selector valve starting at step 19.
Any Quick Disconnects (QDs) or hose handles on those
hoses are transferred or replaced.
The kit includes two new hitch hoses to the tractor. For
newer drills (with hose handles), continue at “2012+

(without hose handles), continue at “2011- Remove/Add
Quick Disconnects” on page 6.
