Attach cutter to the tractor that will be pulling thecutter and position tractor and cutter on level ground.2. Raise both wings up and lock into position withtransport locks to keep wings from falling. See“Transport Locks” on page 27.3. Using hydraulic lift, adjust center deck height so thatthe front skids (#7) in Figure 2-2 are 2 to 3 inchesabove ground.4. Shut tractor down properly before dismounting. Referto “Tractor Shutdown Procedure” on page 12.5. On both sides of the center deck are hinge rods (#2).Measure from ground to bottom of hinge rods at thefront and back. The hinge rods should be 1" closer tothe ground at the front than they are at the back.If continuous hinges are too high at the front:a. Loosen jam nuts (#3) several turns.b. Unscrew adjusting nuts (#4) clockwise an equalamount to lower front of cutter until both hingerods are inclined from front to back by 1" with thefront closer to the ground than the back.If continuous hinges are too low at the front:a. Loosen jam nuts (#3).b. Tighten adjusting nuts (#4) counterclockwise anequal amount to raise front of cutter until bothhinge rods are inclined from front to back by 1"with the front closer to the ground than the back.6. Raise center deck up to make accessing jam nuts(#3) and adjusting nuts (#4) easier with wrenches.37530NOTE: Lengthen leveling rods to lower front ofcutter; shorten leveling rods to raise front of cutter.Park Jack Angle AlignmentFigure 2-1Park Jack Angle AlignmentRefer to Figure 2-1:The jack mount angle should be adjusted to position thepark jack vertical while supporting the cutter hitch. Thisangle will vary depending on the number and size ofstroke control spacers placed on the lift cylinder rod.1. With cutter hitched to a tractor, lower cutter to storageheight.2.
