Minneapolis-Moline RC Cultivator

ASSEMBLY

The RC Cultivator will fit all Model BF tractors and any Model A tractor that is equipped with a pivot type hydraulic unit.

The recommended assembly procedures are outlined on the following pages. If followed closely, the implement can be assembled quickly and easily.

Minneapolis-Moline RC Cultivator

TOOL BAR HOLDER

A tool bar holder (13P512) will be needed to mount the cultivator on the tractor. If there is one already on the tractor a new one will not be needed. This part is not supplied with the cultivator and is to be purchased as extra equipment.

Bolt the tool bar holder under the frame channels by means of the two rear bolts in the steering housing.

Bolt the rear of the tool bar holder to the channel sides with the 5/8” x 2-1/4” machine bolts. The latch on these bolts must be to the outside and should swing freely. (Fig. 1)

On all Model A tractors and some early Model BF tractors these side holes will have to be drilled in the frame channels. In this case attach the tool bar holder to the rear steering housing bolts, and using the tool bar holder as a template drill a 21/32” hole in each frame channel.

GANG HEADS

Loosen the clamps on the under side of the tool bar holder. Install the gang heads by slipping the end of the tool bar with the latch plate into the square hole in the tool bar holder. Engage the latch and tighten the clamps securely. (Fig. 1)

LIFTING RODS

Extend the hydraulic piston and attach the lifting roll extension sleeve on the lifting rod to the lifting roll. The set screw on the sleeve should be down and to the rear. Attach the end of the lifting rod to the lifting arm on the gang head. (Fig. 2)

FENDER ASSEMBLY

Attach the fender assembly arm to the tool bar with a “V” bolt. The arm should point straight down. Bolt the fender assembly lifting arm to the lifting shaft on the gang head. This arm must be at right angles to the gang head lifting arm. Attach the fender assembly lifting chain to the fender assembly lifting arm. (Fig. 3)

BEAMS

Bolt two beams to each gang head. The outer beam should point out and the inner one in. (Fig. 4)

Minneapolis-Moline RC Cultivator

Bolt the sweeps to the standards. Attach the standards to the beams with the standard clamps as shown in Fig. 5. The half sweeps are to be used next to the rows.

REAR SWEEP ATTACHMENT

In order to install a rear sweep it will be necessary to first install a hitch plate on each rear axle housing. These plates are not supplied with the implement and must be purchased as extra equipment. Attach one plate to the inner side of each rear axle housing as shown in Fig. 6.

SIDE BEAMS

Loosen the tail nut in each side beam assembly, and attach them to the hitch plates as shown in Fig. 7. Tighten the tail nuts securely.

Minneapolis-Moline RC Cultivator

CENTER BEAM

Loosen the two tail nuts in the center beam assembly, place the drawbar in the center position and install the assembly as shown in Fig. 8. Make certain the rivets fit in the holes before tightening the tail nuts.

Minneapolis-Moline RC Cultivator

HOBBLE ASSEMBLY

Attach the hobble assembly to the side beams. Install the lifting rod and spring to the center beam and to the hobble. The lock collar on the rod should be on top of the hobble assembly. (Fig. 9)

LIFTING ARMS

Connect the lifting arms to the side beams and to the lifting roll extension. Attach the arms to the lifting roll extension as shown in Fig. 10.

REAR STANDARDS & SWEEPS

Bolt the sweeps to the standards and attach the standards to the beams with the standard clamps. (Fig. 11)

OPERATION

This section of the manual explains the various operating adjustments necessary to meet varying field conditions. The operator should use his own judgment and make only the adjustments necessary to make the implement operate satisfactorily.

SPRING TRIP STANDARDS

If the spring trip foot trips too easily, turn the adjusting bolt out far enough to get the desired action, turning the adjusting bolt out makes the foot harder to trip. If the adjusting bolt should become lost, the foot will not go past center and it will always trip if sufficient pressure is applied. Turning the adjusting bolt in makes the foot trip easier. (Fig. 12)

The spring tension should not be changed to make the foot easier or harder to trip.

SWEEPS

All sweeps should be set as flat as possible and still get the desired penetration. The sweep adjustment is accomplished by turning the sweep adjusting bolt on the spring trip standard in or out. (Fig. 12) Turning the adjusting bolt in tilts the point of the sweep up and turning it out tilts the point down.

ROW WIDTH

Rows from 30 to 44 inches can be cultivated with maximum crop clearance. Rows under 30 inches can be cultivated only if the crops are low such as beets or beans. Tall crops such as corn can not be cultivated in rows less than 30 inches.

Various width rows can be cultivated by moving the gang heads on the tool bar in or out, to do this, loosen the “V” bolts that attach the heads to the tool bar and then move the heads. (Fig. 13)

Retighten the bolts securely. The standards may also be loosened from the beams and moved to the desired position. In some cases it may be necessary to use fewer standards or different size sweeps to properly cultivate the rows.

FENDERS

The fenders can be tilted up or down at the front end by loosening the bolts shown in Fig. 14, tilting the fender and then retightening the bolts, the blades may be spread by the adjustment on the spreader arms. (Fig. 14)

Minneapolis-Moline RC Cultivator

BEAMS

The height of the beams should be the same at both ends, adjustment is made by lengthening or shortening the adjusting link. (Fig. 15)

GANG LIFTING RODS

The springs on the lifting rods should be free when the sweeps are resting on the ground. In operation, the spring will be compressed, depending on the depth of cultivation.

The nuts on the top of the rods are provided to keep the right and left hand sections level and should not be used to increase pressure on the springs.

The set collars on the lower ends of the rods can be used to increase the spring tension. This should only be done in extremely hard soil. (Fig. 15)

HAND LEVERS

These levers are provided for depth control from the operators seat. Either the right or left sections can be raised or lowered independently of each other. This provides an easy way to cultivate point rows or to get additional depth on one side.

The hand levers should be set midway on the quadrants to provide adjustment in either direction.

An adjustment is provided where the rods attach to the gang heads. This is so that both right and left hand gang heads can be kept even with each other.

REAR SWEEP

Both side beams should be even with each other. This adjustment is accomplished by tightening or loosening the tail nuts on each lifting arm. These tail nuts should be adjusted to get the beams even ano so that there is freedom between the ferrule and trunnion when operating. The shovels should raise at the same time as the rest of the implement.

The center beam should be adjusted so that it will raise with the two outer beams. To adjust, move the collar up or down on the lifting rod.

DISC HILLERS

Disc hillers are available as extra equipment. They may be attached in place of a standard as shown in Fig. 16.

TRASH CLEARANCE

In some cases trash may accumulate between the inner rear sweeps. In this case it is recommended that the inner rear standards be staggered on the beams. To accomplish this, loosen the standard clamp bolts and slide the standards along the beam. Fig. 17 shows the sweeps in a staggered position.
