TROUBLE

1. Loss of ear corn in the field.

2. Plugging.

3. ExcesSive shelling.

4. Beater not taking t r ash a way fast enough.

CAUSE

(a) Gathe ring unit not centered on row s.

(b) Ground speed too fast or too slow.

(c) Not picking planter rows.

(d) Gathering unit being operated too high.

(e) Corn head not operating at proper R.P.M.'s to match harvesting conditions.

(f) Gathering chains not timed properly .

(g) Thin stand of corn

(a) Gathering unit not centered on rows.

(b) Ground speed too fast or too slow.

(c) Corn head not operating at proper R.P.M.'s to match harvesting conditions.

(d)Stripper plates not adjusted properly.

(e) Snapping rolls not adjusted properly.

(f) Gathering chains not adjusted prop­erly (in or out) causing them to clip off stalks.

(g) Knives below snapping rolls not ad­justed pro per I y causing rolls to wrap.

(h) Shear plates and roll plates worn excessively.

(a) Stripper plates set too wide allowing ears to get into the snapping rolls.

(b) Ground speed too fast.

(c) Gathering unit raised too high.

(a)Excessive amount of trash being processed.

TROUBLE SHOOTING

CORRECTION

(a) Keep the machine centered on the rows to avoid missing ears.

(b) Operate at a speed to match the yield and ground conditions.

(c) Pick rows as they were planted.

(d) Lower the gathering unit. Floating shoes should just touch the ground. Readjust shoes. See Page 6, Fig. 2.

(e) Speed up or slow down unit to match h a r v est i n g conditions. See Page 11, Fig. 15.

(f) "Finger Links" must be halfway between each other. See Page 7, Figs. 3, 4 & 4A.

(g) Install rubber ear savers at lower end of rolls. See Page 16, Fig. 32 .

(a) Keep the machine centered on the rows to avoid stalk breakage.

(b) Slow down machine to meet crop conditions.

(c) Speed up or slow down unit to match h a r v est i n g conditions. See Page 11, Fig. 15.

(d) Readjust stripper plates. See Page 8, Figs. 5, 6 & 7.

(e) Readjust snapping rolls. See Page 9, Figs. 8 & 9.

(f) Readjust gathering chains. See Page 7, Figs. 3, 4 & 4A.

(g) Readjust knives. See Page 9, Fig. 10.

(h) Replace shear plates and roll plates. See Page 9, Fig. 10.

(a) Readjust the stripper plates. See Page 8, Figs. 5, 6 & 7.

(b) Slow down unit to match crop and har­vesting conditions.

(c) Gathering unit should be operated well below ear height.

(a) Install extra claws or rubber paddles on beater to process material faster. See Page 11, Fig. 16.

OPERATING AND ADJUSTING (CON'T)

Gathering Chains

Figure 3

Figs. 3, 4 & 4A -

Finger Link Spacing The gathering chains must be operated with finger links "A" (Fig. 3) staggered haliway between each other.

Chain Adjustment (In & Out)

Various crop conditions require the gathering chains to be moved in or out. In normal conditions the chains should be adjusted soto have 3/4" between the galvan­ized sheet metal and the edge of the chain slide as in­dicated in Fig. 3. The chains should be set to most effectively move the stalks into the rolls. Moving the chains closer together will make them more aggres­sive. However, in severe conditions of down and rot­ten stalks, they should be adjusted so they do not clip off the stalks. To adjust the chains, the slides will have to be moved, place a 3/4" socket wrench on bolts "B" (Figs. 3 & 4 - top and bottom) and adjust the slides as desired. NOTE: After making this adjustment, make sure to

readjust the pressure springs to the 3-9/16" dimension indicated in Figure 4.

Chain Speed See Page 11, Fig. 15.

Figure 4

Figure 4A

Spring Pressure The gathering chains are spring loaded through the sliding idler assemblies "C" (Fig. 4). A constant spring pressure should be maintained at all times. The 3-9/16" spring dimension indicated in Fig. 4 is the way they are shipped from the factory. This di­mension should be maintained. NOTE: Make sure to check this dimension when adjust­

ing the chains in and out.

Gathering Chain Drive Sprocket Alignment

The gathering chain drive sprockets "D" (Fig. 4A) must be kept in perfect alignment with clutch sprocket "E". Should the chain, sprockets or the gear box ever be removed, check to see that they are aligned prop­erly. To align them, add or remove washers on the back side of the sprockets.

OPERATING AND ADJUSTING (CON'T)

Feeder House Conveyor Chain and Scraper

Figure 11

Conveyor Adjustment

Figs. 11 & 12 -

The conveyor is equipped with a spring loaded hold down device shown at "A" (Fig. 11 - both sides). Its purpose is to keep the material moving evenly. It is adjusted at the factory and no further adjustment is required. To adjust the conveyor, adjust nuts "B" (both sides) to the point where the flights just clear the bottom of the feeder house.

Figure 12

Scraper Adjustment Scraper "C" (Fig. 12) must be adjusted as close to the upper shaft as possible to prevent wrappage. Loosen the bolts attaching the bottom pan and the mounting bolts on both ends of scraper to adjust it.

Protective Devices-Slip Clutches and Shear Bolt for Snapping Rolls

Figure 13

Slip Clutches Figs. 13 & 14 -

Clutch "D" (Fig. 14-one per row) protects each set of gathering chains.

Clutch nE" (Fig. 13) protects the auger and beater. Clutch "F" (Fig. 13) protects the feeder house conveyor.

Shear Bolt for Snapping Rolls

Shear bolt "G" (Fig. 14) protects the snapping rolls. When replacing it, use a 5/16x 1-3/4" special hardened Grade 5 machine bolt.

ASSEMBLY PROCEDURE (CONT'D)

Removing crating from back side of unit, installing cylinder bell and trash deflectors.

Figure 20

(I Figs. 20 & 21 - NEVER UNDER ANY CON­• ~e DITION SHOULD YOU TRY TO LOWER

THIS UNIT WITHOUT USING A LOADER e. OR HOIST. REMEMBER: "SAFETY IS NO

. ACCIDENT".

After attaching a loader or hoist to the upper end of the unit, remove the crating from the back side of it. Install R.H. cylinder bell "G" (Fig. 20) using a 3/4 x

Snapping Roll and Stripper Plate Control Levers

Figure 22

Fig. 22 - Position the snapping roll and stripper plate control levers onto the lever sectors as shown. Secure in place using a 3/4" LD., x 1-1/2" O.D., x 2-15/16" long pipe spacer at "C" and 1/8 x 7/8" cotter pins at "D" (both sides). Secure rods to levers at "E" using 1/8 x 1" cotter pins.

Figure 21

4-3/16" drilled pin with 3/16 x 1-1/4" cotter pins. Attach trash deflectors (3) to studs on brackets at "G" (Fig. 21) using 3/8" lockwashers and nuts. Use 3/8 x 3/4" machine bolts at "H" (both sides) with 13/32" LD. x 13/16" O.D., x 1/16" washers.

Reposition jacks "A" (Fig. 20) to the park position as shown.

Lower the unit onto the jacks.

Nos. 701, 702 & 702 D Power Unit Cylinder Position

Figure 23 Fig. 23 - The cylinders on the power unit must be positioned as indicated prior to mounting the stripper plate corn head. However, if the power unit being mounted is a lot US-2 machine, the R.H. cylinder anchor brackets will have to be added to the power unit frame. The instructions to attach these brackets will be found with them.
