The three units are connected to the frame by a double pivot setup. The first pivot point

attaching the mowers to the frame. This articulating free floating system would not be
possible without the complete release of all hydraulic pressure as you will see with the

Telescopic Arms
The two wing mowers are connected to the frame with two adjustable telescopic arms

each. This unique feature, available only on our mower, allows the wing decks to
telescope in and out for additional overlap. Holes are provided for this purpose (see #1,
fig. 8). With the holes provided, you are able to adjust the cut overlap by up to 6” per
side. This is done by removing the retaining bolt and sliding the wing frame in or out to
the desired position (see fig. 8). You may choose to drill holes for additional adjustment
positions.
As the wing units, the central unit is also assembled to the frame with telescopic arms
that are adjustable in several positions (see fig. 10 & 11).
Important: Always check
PTO length when adjusting the deck overlap.

The second pivot point is where the telescopic arms connect to the mowers. Each deck
has two pins, one in the front and one in the rear, nested between two stamped plates
with large slots. The plates are attached to each of the frame arms with three bolts. As
