4. COMPL Y with local lighting, marking and maximum wid th regulations when transporting on highways.

WARNING

IMPORTANT INFORMATION ON 16 & 20 FT. HITCH MACHINES

WITH NEGATIVE HITCH WEIGHT

Because of the large wing size of certain Summers Culti-Harrows and because of the added weight on all Summers Superweeders and Superharrows, the hitch on these machines often becomes “light” in transport position. This means that there is no downward weight on the hitch and as a result, the hitch will rise if unhitched. In these cases, special precautions must be taken as discussed below. This condition can exist even if the hitch is equipped with a spray or granular attachment.

NEVER unhitch a machine that has been opened up into field position and has not been completely lowered to the ground. If the machine has been completely lowered to the ground and parked in a level area, it may be unhitched with ordinary care. NEVER unhitch a machine in transport position from a tractor, pickup, truck or other towing unit unless the following precautions are taken.

1. Determine if the hitch has a positive or negative weight. Insure that there is no side pressure on the hitch pin before determining positive or negative tongue weight. If the Culti-Harrow, Superweeder and Superharrow’ s hitch piece or clevis is resting on the towing unit’s hitch and cannot be lifted off, positive tongue weight exists. The machine can be unhitched by lowering the hitch jack, stabilizing with one wing tube jack and following steps 2 and

4. If positive tongue weight does not exist, follow steps 2 through 4.

2. Park the machine on a level area and block the hitch tires and wing transport tires so the machine cannot roll forward or backward. This is very important even if the machine is parked on level ground, strong winds often move unblocked machines.

3. Lower the wing tube jacks until enough weight is transferred to the hitch to keep it from rising. Check this by observing the machine hitch. With the hitch pin installed but not binding with the machine hitch, check that the machine hitch no longer has a tendency to rise.

4. Disconnect all hydraulic lines. Again check that the hitch pin is free. There should be no side force on the pin and it should turn freely . If free, st and of f to the left side of the hitch and remove the hitch pin. Carefully drive ahead.

IMPORT ANT : The positioning of the transport wheel assemblies on the wing tubes of the machine is very critical in determining hitch weight. Moving transport wheel assemblies forward will increase hitch weight and moving them rearward will decrease hitch weight.

SECTION 2 – SET-UP INSTRUCTIONS — CULTI-HARROW

Fig. 1

The machine should be placed in an area that allows ample room for assembly in field position (See Fig. 1).

CAUTION: For safety purposes, block equipment while working on it.

Refer to illustrations and parts listing on pages 8-2 through 8-20 and follow these steps when assembling.

16’ HITCH ASSEMBLY

HITCH, HUBS AND WHEELS

Mount axle plates with spindles down for 1 1L tires and with spindles up for 14L tires. Mount hitch wheels and tires and install hitch jack.

CENTER WING DRAWBAR TUBES FOR 16’ HITCH

Attach center tube to hitch using (2) 1-3/16” x 7-1/4” pins and secure with 7/16” x 3” bolts and locknuts. Attach wing tubes to center tube knuckles using 1-1/4” x 7” pins. When in field position, the locking collar is on top. Insert a 7/16” x 3” bolts through locking collar and hole in top of each pin, secure with locknut. Secure pin with 1” flat washer and 1” NC lock jam nut.

IMPORT ANT: Be sure to install wing tube spindles with spindle down when in field position.

Mount support wheels and tires. Do not mount transport wheel assemblies until lift arms are positioned.

SECTION 2 – SET-UP INSTRUCTIONS — CULTI-HARROW

Fig. 2

20’ HITCH ASSEMBL Y

Bolt the two A-frame sections of the hitch together, using eight 7/8” bolts and locknuts. NOTE: Since these larger pieces have a tendency to warp when welded, it may be necessary to pull the legs of the hitch

together to match the center tube brackets.

Mount axle plates with spindles down for 1 1L tires and with spindles up for 14L tires. Mount hitch wheels and tires and install hitch jack.

CENTER WING DRAWBAR TUBES FOR 16’ HITCH

Attach center tube to hitch using (2) 1-3/16” x 9-1/2” pins. Secure with 7/16” x 3” bolts and locknuts. Att ach inside section of hinged-wing with 1-1/4” x 7” pin and secure with 7/16” x 3” bolt and locknut. Secure pins with 1” flat washer and 1” NC lock jam nut.

Attach outside wing and secure with 1-3/4” x 9-3/4” pin, 7/16” x 3-1/2” bolt and lock nut. Mount wing tube spindles with spindle down in field position. Do not install transport wheel assemblies until lift arms are positioned.

SECTION 2 – SET-UP INSTRUCTIONS — CULTI-HARROW

LIFT ARMS

Attach the lift arms to the wing tubes using 7/16” x 7-1/4” bolts. Start at machine center and measure outward using the following guide.

All measurements are to the center of the lift arms. The end lift arm on each wing should be close to the end wheel so the section harrows out the wheel track.

In cases where both 5-1/2’ and 7’ sections are used on the wings, the 7’ sections are used on the ends.

SECTIONS:

Assemble 5 bar section linkage as shown in figure 4. The sections are attached as shown in figure 3. Connect the 8-

link pull chain to the middle hole of the lift arm using a clevis pin and hair pin. Connect the 6-link pull chain to the bottom hole of the lift arm using a 1/2” x 2” bolt, lockwasher and nut. Position harrow section as shown and secure using a 1/2” x 2” carriage bolt, flat washer and lock nut to attach one chain on each side of bracket.

Attach the 9-link lift chain to the lift arm with a 7/16” x 2” bolt. Attach the lift chain to the section with a 1/2” x 1-1/2” carriage bolt inserted in the front hole.

OPTIONAL SPRING PRESSURE

To assemble the optional spring pressure to the lift arms, first insert an eye-bolt through the lift arm with the eye toward the outside of the harrow section (See figure 5). Attach other end to the harrow section with a 1/2” x 2-1/4” bolt, lock washer and nut. Install a bushing between the eye-bolt and section as illustrated. Repeat for the other side of the section.

TRANSPORT WHEELS

Install the transport wheel as shown in Fig. 1. Place the transport wheel assembly over the end section on units up to 56 ft. On sizes over 56 ft., install over the second section or between end sections. On the 84 ft. model, install wheel between the two end sections. On the 98 ft. model, install wheel over the second section from the end. On the 112 f t. model, install wheel between the second and third sections from the end.

Secure with two 5/8” x 5-1/2” bolts, lock washers and nuts.

NOTE: Transport wheel brackets are made for left and right and are not interchangeable.

IMPORT ANT: The positioning of the transport wheel assemblies on the wing tubes of the machines is very critical in determining hitch weight. Moving transport wheel assemblies forward will increase hitch weight and moving rearward will decrease hitch weight. See the “Warning Regarding Machines With Negative Hitch Weight” on page 1-2 for

more information.

WING TUBE JACK BRACKET

Harrows without sprayers on hitch may require the transport wheel assemblies to be positioned further ahead to provide a better balance on the hitch. A wing tube jack bracket is provided with all machines and allows for mounting the hitch jack on the wing tube for added stability . (See Fig. 6).

CABLES

Install cable brackets and cable assemblies as shown in figures 1, 2 and 7. Secure brackets using 3/4” U-bolts, lock washers and nuts. T wo cables are required for each wing on the hinged wing models.

T o prevent outside cable from catching on transport tire on 1 12’ Culti-Harrows, install cable guides directly behind transport tire as shown on page 8-10.

NOTE: Adjust cables so wings slightly lead center when standing in field position.

IMPORTANT: On machines with two cables per wing, the cables must be adjusted to have equal tension.

HYDRAULIC SYSTEMS FOR MACHINES WITH 16 OR 20 FT. HITCHES

Mount lift cylinders and assemble hose lines as shown in figures 19 and 20.

NOTE: The hydraulic line leading from the rod-end of

the lift cylinders requires a restrictor valve on the tractor end. Thread this valve on with the arrow pointing back towards the cylinders as illustrated.
