4.0 PREPARATION

4.1 Tractor Preparation

4.1.1 Adjusting the Drawbar:

It is recommended that the trac-

tor drawbar be set to the shortest position and be within the
given range (in accordance with ANSI/ASABE AD6489

3) to

maintain the integrity of the drive system. Dimensions are
shown in Figure 4

IMPORTANT

Ensure the driveline remains within operating range under all conditions.

4.1.2 Tire Spacing and Inflation:

Tires should be inflated to the manufacturer

’

s specification. See Sec-

tion 3.3, Traction, for more information. Figure 4

shows the appropriate tire spacing.

A = 3 or 4 * B

B = Row Spacing

C = Tire Width; must be as narrow as possible.

IMPORTANT:

Tires must be narrow enough not to con-

tact beets when driving down rows while still providing
enough traction to pull the harvester.

NOTE

The Front tires must be aligned with the rear

tires.

4.1.3 Three

Point Hitch Position:

Three

point hitches cannot be

connected to the hitch when using an Amity beet harvester. It
must be fully raised or removed.

NOTE:

Amity recommends removing three

point hitches.

CAUTION:

Ensure the receiver and drawbar support arms

clear the PTO driveline under all conditions.
