Operating Instructions

3.5 Settings

The drawbar may be attached to the tractor

rigid drawbar or the pick up hitch. Altering the

length of the drawbar adjuster (C) will raise

or lower the back of the frame to alter the

draught requirements and quality of work. The

drawbar adjuster may also be used to take

account of varying tractor drawbar heights.

Alteration of working depth is effected by

altering the length of the top link on each wheel

unit (A). Both wheel units must be set to exactly

the same length. Remember to check the

wheels for clearance after any adjustment.

The tie bars should NEVER be removed,

therefore should reduced depth still be

required when working at the limit of the tie

bars; the tines will need to be raised in their

clamps.

To adjust working depth proceed as follows: -

Raise the machine and drive forward onto

hard ground. Lower the machine fully to

eliminate pressure in the hydraulic system.

Retain the hydraulic lever in the ‘lower’ or ‘float’

position, then lengthen the adjusters to

decrease depth or shorten to increase depth

as required.

When entering work ensure that the transport

locking units are removed, then lower the

tines to the ground, draw forwards until the

correct operating depth is achieved. In work

the hydraulic cylinders (B) should be in the fully

closed position. To leave work, extend the

hydraulic cylinders so that the tines are clear

of the ground.
