General description

The FTZ Force boom is available in 28, 30, 32, and 36 metre working widths but may also be operated partially

folded if required producing a working width of approximately half it's total length. Other features include 3

dimensional cross section steel construction, remote hydraulic movement control and coil spring suspension, and

a sturdy welded steel boom centre assembly. The boom is equipped with individual wing tilt control, which along

with the raising, lowering, folding and unfolding functions is operated via the tractor's auxiliary hydraulic system.

Outer sections incorporate spring loaded breakaways for impact protection.

Terminology

Terminology used within this manual to describe the various boom sections is as follows:

The hydraulic system for the FTZ Force boom requires a 12 volt power supply to operate the control system plus

one single acting and one double acting hydraulic outlet. The single acting outlet controls boom lift up and down,

whilst the double acting outlet controls wing fold and tilt functions. Oil ﬂ ow of approximately 5.7 litres per minute at

approximately 145 bar (14500 kpa or 2130 psi) pressure is required for correct operation. The constant speed of

hydraulic movements is maintained by an in-line adjustable ﬂ ow regulator.

Warning: Due to variations in tractor hydraulics and capacities, care should be taken when operating

the hydraulic system for the ﬁ rst time. It is advisable to adjust the hydraulic ﬂ ow control (see description

this section) down to the minimum rate before operating the system. Adjust / increase the ﬂ ow rate once

the system is bled of any air and is functioning correctly.

Warning: Ensure hydraulic lines have not been damaged during shipping. Initial connection and testing

of the hydraulic system should be done cautiously. Incorrect connection of hoses or air trapped in the

system can cause unexpected or violent boom movements.

Warning: Always shut the tractor down when connecting, servicing or adjusting boom hydraulics. Never

use your ﬁ ngers to locate a leak in a hydraulic system, use a piece of cardboard. Always wear safety

glasses, gloves and protective clothing. High pressure oil can penetrate skin and cause serious injury.

Note: Ensure all ﬁ ttings are tight and snap couplers are free of moisture and foreign material before

connection. After having operated the boom and the system has ﬁ lled with oil, check the tractor's

hydraulic oil level and top up with the recommended product if necessary.
