2. ROLLER SPACING. This depends upon the type of grain to be rolled. Different grain varies in
size, shape, toughness and moisture content. This is also true of the same kind of grain from
different localities. For this reason, it is impossible for us to tell you how to set the rolls. Do not
over-roll hard or dry grains, as this will cause dusting. Remember, proper adjustment keeps dust
at a minimum, even when rolling the driest grain.
The closest roll setting is preset at the factory and as a rule and should not require additional
adjustment. However, for certain types or conditions of rolling, some “ne tuning” may be required.
IMPORTANT - Check to make sure the roll teeth do not come in contact with each other by turning
the mill by hand after each adjustment.
DON’T OVERCROWD THE ROLLS - keep a ribbon of grain going between the rolls, and you’ll do a
better job of rolling. This is especially true of oats and barley. It is not necessary to completely atten
the kernel. The grain becomes easy to digest when the hard coat or hull is broken open, exposing the
nutrients to the digestive juices.
ON PTO UNITS - Grade 5 shear bolts should be used at all times in the shear plate of the PTO
assembly.
ALWAYS - ease the PTO in slowly with tractor idling, then increase RPM gradually to full throttle,
900 to 1,000 RPM. Always maintain full tractor throttle and PTO speed while operating mill. NEVER
OPERATE WITH PTO SPEED IN EXCESS OF 1,000 RPM.
TRACTOR HITCH (see illustration below) - The hitch of the roller mill is designed to attach to any
SAE-ASAE standardized tractor draw bar. Adjust the draw bar so that it is 13” - 20” above the
ground. Extend or shorten the tractor draw bar so that the horizontal distance from the end of the
tractor power take-off shaft to the center of the hitch pin hole is 16” for 1,000 RPM. Lock the draw bar
in its crossbar, parallel with the center line of the tractor. Place locking pins on each side of the draw
bar. If the tractor has an offset draw bar, the offset should be down for PTO work.
THE TRACTOR HITCH POINT MUST BE PROPERLY
ADJUSTED. AN IMPROPERLY LOCATED HITCH
POINT MAY CAUSE DAMAGE TO THE POWER
TAKE-OFF WHICH MAY LEAD TO PERSONAL
INJURY.
NEVER ATTEMPT TO LUBRICATE, ADJUST OR OTHERWISE
SERVICE THIS MACHINE UNTIL THE PTO HAS BEEN
DISENGAGED, THE TRACTOR ENGINE HAS BEEN
TURNED OFF AND ALL MOTION HAS BEEN
STOPPED. LISTEN, AS WELL AS LOOK,
FOR MOTION BEFORE PROCEEDING
BEARINGS - All pillow block and cast ange bearings are sealed and as a general rule, require no
lubrication. However, the bearing manufacturer does furnish grease zerks and recommends the
bearings be regreased before one-third (1/3) of the bearings’ calculated life elapses. Usually just a
pump or two of grease per bearing before start up each harvest or after the unit has not been used for
a month or more will be sufcient.
IMPORTANT - DO NOT OVER GREASE. Over greasing can cause damage to the bearing seal.
WHEEL BEARINGS - Trailer wheel bearings should be cleaned and repacked with grease on a yearly
basis.
PTO Cross bearings should be greased daily. Telescoping sections of the PTO should be greased
yearly.
