TRACTOR REQUIREMENTS
AND PREPA R ATION
The One and Two Bottom Moldboard Plows provide
excellent soil tillage for small and hobby farms. Each
plow has shear-bolt protection to protect the unit from
underground objects.
The “low profile” one bottom 12” plow is designed for
small tractors having low profile configuration and a Cat.
O (20” spacing) or a Cat. I (26” spacing) with 7/8” pull
pins.
Coulters and trashboards are NOT available for this
model.
The one and two bottom 14” plows are for standard
size tractors equipped with a Cat. I (26” spacing) 3 pt.
hitch.
Generally, it requires 1 hp for each 1 inch of moldboard
plow width, ie, 12” plow requires 12 hp, 14” plow requires
14 hp, and a two bottom 14” plow requires 28 hp. Small
compact tractors may need to be larger than this general
rule.
Check the tractor’s 3-point hydraulic lift system. It
should operate up and down smoothly and hold its
position when set. Refer to your tractor owner’s manual
or dealer for any adjustments necessary to put the 3point hydraulic lift system in good working order. (I&T
shop manuals will list most specifications and adjustment
instructions – available from most farm equipment
dealers.)
Check the hydraulic system. Be sure the tractor
hydraulic oil and filter have been serviced according to
the tractor manufacturer’s recommendations.
Smaller size tractors may need front counter weights to
counter-balance the weight of the implement.
It is recommended that the tractor be equipped with a
Rollover Protection System (ROPS) and a seat belt that
is used.
It is important that your tractor be properly prepared to
obtain the best and safest operation from your plow. The
following procedures are recommended. In addition,
review your tractor manual for instructions on adjustments and use of three point hitch control features,
ballast weighting, and tire pressures.
BALLAST WEIGHTING
Mounted plows normally require added weight to the
tractor to maintain proper stability and traction during
operation and transport.
1) An 80% tire fill of ballast fluid is usually enough for the
rear tires. It may be necessary in some cases to add
metal weights to prevent tire slippage.
2) Add front end weights if there is floating action on the
front of the tractor when plowing. Approximately 100 lbs.
of additional front end weight is usually needed for each
plow bottom when working in average soil.
3) To determine proper weighting, check the soil
between the rear tire lug prints. When pulling a full plow
load, the soil should be broken or shifted slightly. Too
much weight will cause sharp, firm tread marks. Slippage
results from insufficient weight, will show up in poorly
defined tread marks.
WHEEL TREAD SETTINGS
Fig. 1 & Table 1 (page 9)
The rear tractor wheel measurements should be made
from center line of tractor to inside wall of tires. The right
tractor wheel should be set to correspond exactly with
the right rear wheel as measured to inside walls of the
tires. See table 1 for correct wheel spacings for number
and size of plow bottoms being used.
TIRE INFLATION
Proper tire inflation can be determined by checking the
tire lugs on a cement surface. The tire is correctly inflated if approximately 90% of the lug makes contact with
the surface when the tractor is fully weighted.
COULTER ATTACHMENT
Rolling coulters are recommended to make plowing
smoother and neater. Coulters also make plowing easier
by reducing drag. (Not available on 12” low profile
model.)
NOTE: Quick hitches cannot be used with these 3 pt.
moldboard plows. They must connect directly to the
tractor lift arms.
INSTRUCTIONS
Be sure your tractor is in good condition and
properly equipped with counter weights. Read all the
safety precautions and make sure all tractor
operators are familiar with the safety rules of tractor
operation.
CAUTION!
