ASSEMBLING INSTRUCTIONS

Right or left side is determined when facing the same direction the drill is to travel.

Sort all parts shown in Plate No. 1, and assemble according to directions given under that plate number. All parts shown in each plate are numbered and should be assembled in that rotation. Each part number corresponds with each paragraph of the same number. These numbers are also followed through on each illustration showing that particular part installed: i.e., pick out part number (1) shown in Plate No. 1 and look for the same number on an illustration referred to as a Fig. Number which will show that particular part installed.

After all parts shown in Plate No. 1 have been assembled, follow the same procedure as outlined under Plate No. 2 and so on until the assembly of the drill has been completed.

NOTE: Drills equipped with power lift, and/or grass seed attachment require that the drive sprocket be assembled on the axles before bolting them in place. See power lift instructions, or grass seeder instructions.

A series of cutoff gates, one for each feeder foot or star wheel, is located to the rear of the back plates or sheds. These gates are controlled by the dial lever on the outside of the hopper for the purpose of opening and closing the throat of the feed through which the fertilizer is forced by the revolving of the feeder fingers in the bottom of the hopper.

NOTE: The amount of fertilizer sown will vary in quantities depending on the moisture content and quality of the fertilizer.

CARE OF FERTILIZER FEEDS

When sowing damp fertilizer, do not start the drill after it has been permitted to stand for a few hours without first stirring the fertilizer clear to the bottom so that the fertilizer feeder feet are not stuck because of the cementing action of the fertilizer.

Minneapolis-Moline Monitor Drills

Do not leave fertilizer in the hopper when the drill is not in use, as it will cause corrosion and damage to the working parts.

Feeder feet force the fertilizer out of the gate and into the conductor tubes leading to the soil. They revolve continuously to the right and therefore force some of unsown material to the left end of the hopper. This action sometimes gives one the impression that the right-hand end of the drill is sowing more than the left, which is not correct as all feeds sow evenly.

SAFETY BREAK PIN

The soft break pin in the end of the feeder foot wheel drive stem is a safety pin that shears when stone or hard substances block the feeder feet or when parts become badly caked with fertilizer, thus preventing gear breakage or other damage.

When a pin breaks, drive out the remaining pieces and replace with a new pin. Do not use a nail or hard wire for this purpose.

Minneapolis-Moline Monitor Drills

CLEANING FERTILIZER FEEDS

Always clean the fertilizer feeding mechanism thoroughly.

Remove the shed plate, gate, and knocker. Turn the feeding finger wheel 1/8 turn to the left and lift out. Hard and caked fertilizer can easily be removed by saturating parts with kerosene and chipping off with chisel or putty knife. Wipe kerosene from parts before filling box with fertilizer.

ROW CROP PLANTING

For row crop planting, it will be necessary to cover the grain and fertilizer feeds not used with feed stops to obtain width of rows desired. Stops are furnished from company stock as repair parts extras.

LUBRICATION

The life of any machine depends largely on the care given it, particularly lubrication. This drill is equipped with high-pressure fittings to make lubrication positive and easy. We recommend the use of SAE-160 oil for lubricating all working parts. The use of heavy grease should be avoided.

Each fitting should be lubricated twice each day or after 25 to 30 acres of work, depending upon field condition and the rate of travel.

OPERATING INSTRUCTIONS

PREPARE FOR STARTING

Before starting the drill in the field, be sure all bolts, nuts, and pins are tight, and that all cotter keys are spread.

Examine all grain feeds for nuts, bolts, and other material which may have been dropped into the feed cups while assembly was being made. Serious damage may result if neglected.

PROPER HITCH (TRACTOR DRAWN)

The drill should be hitched to the tractor so that the hopper is level or tilted slightly forward. This is accomplished by adjusting the clevis on the drill hitch bar.

If the tractor has a high drawbar, the drill hitch bar can be placed on top of the drill hitch instead of under it, as usually is the case.

Keep the tractor drawbar pinned in one position to prevent swinging of the drill.

Hitching the drill so the hopper is level will result in uniform distribution of seed, even depth of planting and covering in well prepared, clean seed beds.

When drilling in hard or trashy seed bed, hitch the drill so the box is tilted slightly forward to secure better penetration and trash clearance.

Hitching the drill so it is tilted too far forward causes the disc furrow openers to swing too far back and up, allowing the boot opening to be up above the ground line, requiring deep disc penetration to cover the seed in the furrows.

Hitching the drill so it is tilted too far back causes the disc furrow openers to swing too far forward, allowing the seed to be planted too deep, and sometimes results in the discs not turning properly. A drill hitched in this position will not handle trash as well as it should.

DISC SCRAPER-SINGLE DISK

“T” scrapers are only used when drilling in sticky soil that sticks to the disk. Do not use them except when necessary. They may be pressed against the spring and pulled back when not in use. See Fig. 52.

Minneapolis-Moline Monitor Drills

DISK SCRAPER-DOUBLE DISKS

Examine scrapers before using: occasionally they are damaged in transit and require adjusting. Inside and outside scrapers are adjustable and should be adjusted as light as possible to prevent unnecessary wear. Outside scrapers are adjusted by means of the coil springs, turning the spring in either direction until the desired pressure has been reached. See Fig. 53. Outside scrapers should be used only when drilling in heavy sticky soil.

PRESSURE ROD SPRING ADJUSTMENT

When pressure is applied to the furrow openers, it should be uniform. Lifting levers must always be in the same notch in the ratchets, as must the depth regulating levers on the power lift attachments. The spring pressure on each furrow opener should be the same and may be increased or decreased by raising or lowering the adjusting washer on the pressure rod according to ground conditions.

SETTING THE HAND DIAL FOR SEEDING

Set the hand dial so that the turned back edge engages the dial plate at the notch representing the amount of seed wanted sown per acre as shown on the seed table. Move the hand dial past the required setting, then move it back to the predetermined notch on the dial. This will insure that all the slack has been taken out of the feed parts and that all feeds will sow uniformly. See Fig. 54.

CAUTION: Never attempt to reduce appreciably the amount of grain to be sown while the feed cups are full of grain and the seed shaft is not being rotated.

CHANGING GRAIN SEEDING SPEEDS

Tests on wheat and coarser grains have shown that a high speed gear, resulting in a faster revolving feed shaft, and with the fluted feed cylinder partially closed, will produce a more even and continuous flow of seed than a low speed gear setting with the cylinder opened sufficiently far to sow the same amount of seed. This is true unless the seeds are so dry or so large that a narrow opening of the fluted cylinder would cause them to crack.

The use of high or low speed gears depends greatly on what is being sown, the amount per acre, and the condition of the seed.

Generally speaking, use the high-speed gears when sowing one or more bushels of ordinary quality wheat or other coarse grains per acre, and use the low speed gears when sowing less. If, for any reason, there is evidence of injury to the seed, change the gears to low speed and reset the dial to correspond with the amount to be sown with the low speed gear setting.

CAUTION: Always be sure that both right and left-hand gears are set at the same speed; otherwise, different quantities of seed will be sown from the two sides of the hopper.

Minneapolis-Moline Monitor Drills

TO CHANGE GEARS TRACTOR DRAWN

For low speed, the intermediate gears are meshed with the smaller gear on the axle and the larger gear on the feed shaft as shown in Fig. 55. They are bolted to the bracket through holes numbered “1” to “1”.

Minneapolis-Moline Monitor Drills

For high speed, the intermediate gears are meshed with the larger gear on the axle and the smaller one on the feed shaft as shown in Fig. 56. They are bolted to the bracket through holes numbered “2” to “2”.

Minneapolis-Moline Monitor Drills

TO RESET FEED CUPS

It is quite improbable that it will ever become necessary to make any adjustments on the feed mechanism. The drill may be tested by moving the hand dials until all the cups should be completely closed. If any of the cups are left partly open, loosen the bolts with which they are attached to the hopper and move the cups on the feed shaft until they are all closed. The bolt holes in the bottom of the hopper are slotted for this purpose then tighten the bolts again. See Fig. 57.

Minneapolis-Moline Monitor Drills

TO CHANGE GEARS HORSE DRAWN

For low speed, the intermediate gears are meshed with the smaller gear on the axle and the larger gear on the feed shaft as shown in Fig. 58. They are bolted to the bracket through holes numbered “4” to “4”.

Minneapolis-Moline Monitor Drills

For high speed, the intermediate gears are meshed with the larger gear on the axle and the smaller gear on the feed shaft as shown in Fig. 59. They are bolted to the bracket through holes numbered “3” to “3”.

IMPORTANCE OF TESTING SEEDS

The weight and amount of seed sown per acre will vary considerably at any given dial setting, depending on the quality and condition of the seed to be sown.

Damp weather affects the flow of grain to the extent that the quantity sown will not always agree with the amount indicated on the sowing table which has been made up from actual runs of average dry seeds.

Seeds, which are not uniform as to size, quality, or weight, will produce the same results.

For the above reasons you should test your drill before each seeding in the following manner.

  1. Jack up one end of the drill.
  2. Put a canvas or container of some sort under the grain feeds.
  3. Set the hand on the dial at the notch indicating the number of pounds to be sown per acre as shown on the sowing table.

NOTE: When setting the dial, move the hand beyond the notch you want to use, then return it to the required notch for operation.

  1. Put a quantity of seed in the hopper. The hopper capacity is one bushel per foot of length.
  2. Revolve the wheel the required number of revolutions indicated on the following table according to the size of your drill.

SIZE OF DRILL REVOLUTIONS PER ACRE
12-6 605
16-6 454
20-6 363
22-6 330
24-6 301
28-6 259
10-7 620
13-7 477
16-7 387
18-7 344
12-8 452
16-8 339
20-8 271
12-10 362
16-10 271

  1. Weigh the seed that has been run through the drill and check it for any variation.

NOTE: By turning one wheel only, you are using but half of the drill; consequently, the seed run through the drill will be but one-half of that shown on the sowing table. Instead of the total revolutions shown on the table, you may turn the wheel any fractional number of revolutions and check the seed with sowing tables or published weights accordingly.

Remember that the feed mechanism measures quantity and not weight, and that most sowing tables were recorded from average quality of dry seed.

NOTE: The land measure registers the number of acres or fractions thereof according to the number of revolutions of the wheels when the drill is in actual operation.

Minneapolis-Moline Monitor Drills

TO RESET LAND MEASURE:

  1. To release land measure from worm on axle, pull out on the bottom.
  2. Turn bottom worm wheel until the bottom indicator points to zero.
  3. Turn indicator on center circle with pliers or wrench on square post until it points to zero.
  4. Turn upper indicator with pliers or wrench on square post until it points to the largest number.

IMPORTANT: Land measure worm on axle must be kept free from packing with dirt by using kerosene frequently.

ROW CROP PLANTING

For row crop planting, it will be necessary to cover the grain feeds not used with feed stops to obtain width of rows desired. Stops are furnished from company stocks as repair parts extras.

MAINTENANCE

Minneapolis-Moline Monitor Drills

SINGLE DISK OPENERS

Very little maintenance is required for the single disk openers other than regular lubrication with heavy oil, such as SAE-160. The use of heavy grease is not recommended.

At periodic intervals, examine the rubber dust seals (4), Fig. 62. If they show signs of deterioration, they can be replaced at very small expense. Keeping this seal in good condition is very important as it keeps the oil in and the dust out of the bearing resulting in long life and free revolving disks.

Minneapolis-Moline Monitor Drills

DOUBLE DISK OPENERS

Double disks are mounted on spindles and hardened iron bearings held in place by spring tension which automatically takes up any slight wear.

The bearing is prevented from turning by a cotter key through the slot in the outer end and a hole in the disk spindle.

If a bearing becomes worn from lack of lubrication or long use, and the disks begin to wobble or spread apart at point of contact, unscrew the hub cap, remove the cotter key, and turn the bearing (5), Fig. 63, half over, and replace the key and hub cap.

After the bearings have been reversed once, the old bearings can be replaced with new ones.

Never remove the center scraper, but keep it adjusted so that it will not press tightly against the disks and prevent them from turning.

AXLE AND GEAR ASSEMBLY

It if should ever become necessary to disassemble the axle and gear assembly, Fig. 64 shows the sequence in which the parts must be reassembled.

The axle bearings must be kept in such adjustment that there will be no end play in the axle.

Remove the pin from the inside collar “A”, Fig. 64, of the inner axle bearing. Turn the collar and replace pin through slots in collar, which are not as deep as the original setting. If the pin will not go through the axle, file the slot slightly until the pin can be replaced and thus take up the end play in the axle.

Minneapolis-Moline Monitor Drills

PRESS WHEEL ATTACHMENT

Press wheels are equipped with removable bushings and axles which may be replaced when excessive wear occurs. Always replace the bushing before it has worn to the extent that the axle cuts through and ruins the press wheel so a new bushing cannot be installed.

Minneapolis-Moline Monitor Drills

DEEP FURROW LISTER DRILLS, 14-INCH SPACING, 16-INCH DISKS

The deep furrow lister drills have all disks facing in the same direction. The balance of the installation procedure is the same as for single disk assemblies, as outlined in Paragraph 2, Single Disk, Pressure Springs, and Conductor Tubes.

Minneapolis-Moline Monitor Drills

When a change-over is made from a 7-inch spaced drill to a 14-inch deep furrow lister drill, on the 18-7 and 24-7 drills it will be necessary to cover the grain feeds not used with feed stops C-249, which can be furnished from company stock as extras. See Fig. 67. If the drill is equipped with a fertilizer attachment, it will be necessary to cover fertilizer feeds not used.

CARE OF DRILL

  1. Don’t start the drill without examining the feed mechanism to see that the parts have not become rusted tight.
  2. Do not use lubricating oil in the grain feed cups. If they have become rusted, free them up with kerosene.
  3. Grain should not be left in the feed cups after the season is over.
  4. Always grease the disk blades after the drilling season is over to prevent rust.
  5. Never leave fertilizer in the hopper over night. Many kinds of fertilizer will cake in a few hours, resulting in damage to the mechanism if not loosened up before starting drill. If the mechanism has become rusted, free up with kerosene.
