Spearhead Trident 4000/5000/6000
13
With Hoses Only (No Valve)
Connect each hose to a different external spool on the tractor, ensuring the mower
will rise when lever is operated backwards and float when forward.
Fully charge hydraulic rams before removing the transport strap and store safely.
Note: If isolating taps are mounted on wing rams, these should be set fully
open before operating the tractor spool.
Push each control lever forward to lower the mower bodies onto the ground. Once in
work position, set the tractor controls in float, allowing the mower to follow ground
contours.
Setting Up
Height Adjustment
To achieve major adjustment of cutting height; reposition the two side plates carrying
the rear rollers. Ensure the rear roller plates are fixed parallel using the same bolt
holes in all three mower bodies. (Fig. 3).
Finer adjustment to cutting height can be achieved by lengthening or shortening the 2
threaded links onto the drawbar or top link from machine to tractor for the wings, and
the top link to the rear deck
Note: On trailed machines do not over-adjust the front tie bars placing the
drawbar at an acute angle to the tractor. This will cause premature wear
on the towing eye. Always compensate by altering the position of the
rear rollers.
