TRACTOR TIRES (6.1)

In general, set the tractor tires (center to center) at 4x

the row spacing (exe. 120" center to center for 30" row

spacing). The minimum row spacing for the Pluribus

Unit is 22". Make certain that the tires are inflated to

the recommended pressure for your conditions.

The majority of Pluribus Strip-Till users run on 30"

centers, and split the previous years rows. This

typically places the tractor tires running over stalks.

You may want to consider an aftermarket tool

designed to flatten the stalks and reduce tire wear. If

you are equipped with high precision guidance, you

may also consider running at an angle to the previous

years rows. The practice of running at an angle can

also have additional performance benefits in some

conditions.

LIFT CAPACITY (6.2)

Due to the low horse power requirements of the

Pluribus unit, many users will opt for a smaller tractor

to pull the implement. One important factor to

consider, however, is the lift capacity of the tractor

hitch. Each Pluribus unit can weigh in excess of 700

lbs.. If you will be using a mounted toolbar, please

ensure that your tractor is capable of easily lifting the

combined weight of the toolbar, the strip-till units and

any additional fertilizer distribution equipment. Should

your lift capacity be adequate, there is still a potential

that you are excessively tail heavy. If you have

difficulty steering in the transport position, you may

have to add weight to the nose of the tractor.

WARNING!: Driving uphill with a tail heavy tractor is

dangerous! Tractors with excessive tail weight are

susceptible to rollovers.

(Note: The procedure for determining lift capacity on a

tractor equipped with a 3-point hitch can be found in ASAE

S349.2)

THREE POINT HITCH (6.3)

If you have a mounted tool bar, you will want to ready

your 3-Point hitch. Hitches that have seen little use

can freeze up. It is recommended that your free up all

your links in preparation for toolbar leveling

adjustments. Additionally, it is recommended that you

install an aftermarket hydraulic upper link so that you

can quickly adjust the toolbar pitch as field conditions

change.

Tractor Preparation

TRACTOR DRAWBAR (6.4)

The industry standard for tractor drawbars is

approximately 17.5" above ground level. Not all

manufacturers adhere to this standard, nonetheless it

is very important that the toolbar be hitched in such a

way that it can be easily leveled fore and aft. If you

are unable to connect your toolbar in such a way that

it can be easily leveled, please contact Dawn for

advice on your particular tractor/toolbar configuration.

Make sure the drawbar has eyelets for safety chains.

Pulling an agricultural implement without safety chains

is dangerous!

TRACTOR HYDRAULIC SYSTEM (6.5)

Understanding your tractor hydraulic system is

critically important, and you should thoroughly

familiarize yourself with the hydraulic system

instructions provided by the tractor's manufacturer.

HYDRAULIC PRESSURE (6.5.a)

Know the maximum operating pressure of each

hydraulic component. Exceeding the recommended

pressure can result in equipment damage or failure.

Pressure recommendations can be found in the users

manual of most agricultural implements. Also ensure

that there is adequate pressure, should you have a

system that employs multiple hydraulically driven

components.

HYDRAULIC VALVES / COUPLERS (6.5.b)

Hydraulic cylinders are susceptible to abrasion due to

impurities in the hydraulic fluid. It is recommended

that you use a clean cloth to remove any abrasive

particulate that may have collected in and around the

valve plug, and the connecting socket. Always keep

dust covers in place when valve is not in use. Test

your hydraulic hoses and couplers. Make sure there

are no leaks.

WARNING!: Hydraulic fluid under pressure is

dangerous! Small holes in hydraulic lines may eject

streams of fluid at high pressure. Hydraulic fluid that

penetrates the skin can cause serious infection that can

lead to amputation. Should oil penetrate your skin, even

if it is relatively painless, seek immediate medical

attention.
