OPERATION AND ADJUSTMENTS
Blade types
Several blade options are available for GMF Gear drive Wingmower.
–Standard equipment is a flail carrier bar fitted with the swinging flail tip “Gold tips” (Part
No 2365.01 LH cutting top and 2365.02 – RH cutting tip). This offers excellent performance,
lifting the grass to give a clean cut and evenly spread clippings.
–Heavy duty slasher type flails and also mulching type blades are available.
Cutting Height
Cutting height is governed by setting the positions of the rollers and skids. Lowering the
Rollers raises the cutting height and vice versa. The Rollers govern the cutting height of the
whole mower. The wings are able to lift and lower with the undulation of the ground whilst
the PTO is engaged thus providing a float to follow the ground contours. When unfolding
the wings with the hydraulic rams, fully extend the hydraulic rams to their full extent – at
this position, it will allow the wi9ngs to float 100mm below and above the level point in the
float slot located at the end of the hydraulic ram
To adjust the cutting height:
a) Raise the mower on the tractor three-point linkage.
b) Set down the 2 x parking stands ensuring the foot is located on firm ground – engage
the height selector in a hole as required and fasten the lynch pin. Lower the machines
onto the parking stands gently, and ensure the machine is stable.
c)
Start with one roller only. – Loosen the bolts that hold the adjusting quadrant on the
roller and Lift or lower the roller to the required position.
d) Check that both sides of the roller are set to the same height.
e) Tighten all the bolts.
f) Set the other rollers the same as the first one.
g) Replace and tighten all bolts.
Lifting and Lowering the Wings
The wings are designed to float only during operation once the ram has been fully extended
and opened to it extent (giving approx. 100mm of upward and downward float) however
the wings can only be lifted / raised on the hydraulic rams ONLY when the PTO is
disengaged.
