XRD Deck
(Fig. 38)
Your tractor may have been supplied with an XRD
Deck. This deck is primarily used for precision grass
cutting. XRD Decks dispose of grass through a
rear discharge system. For this reason these decks
are ideal for collecting grass with the PGC and net
collector.
Mulching with XRD Decks
A mulcher stiffener plug is available for XRD Decks.
To adapt the deck for mulching attach the mulcher
plug to the deck (fig. 39) and fix in place using
supplied fasteners.
Mulcher to rear discharge conversion
Mulch plugs can be removed when the deck is
installed on the tractor. To switch from a mulch
deck to a rear discharge, lift the deck to its highest
position and undo the two mulch plug fixings at
the rear of the deck. Once undone the mulch plug
assembly is pulled out to make the deck a rear
discharge. In order to convert the rear discharge to
mulch, reverse the procedure so the top stiffener is
back in the deck.
Deck Rotation (fig. 40 & 41)
The XRD Deck is designed to channel grass cuttings
towards the rear of the tractor. In order to function
as intended all deck blades must be installed to
rotate in the correct direction. From the seated
position the deck drive shaft rotates in a clockwise
direction. All blades follow the path laid out by the
internal deck belt and rotate as shown in fig. 40.
Deck blades must be installed to match rotation. fig.
41 shows blade rotation perspective from the base
from under the tractor.
WHEN PERFORMING BLADE MAINTENANCE OR
CHANGING CUTTER BLADES ALWAYS USE A
TORQUE WRENCH TO REPLACE FIXINGS.
BLADES MUST ONLY BE CHANGED BY TRAINED
OPERATORS.
TORQUE VALUES FOR BLADE FIXINGS:
M10 FIXINGS = 50.9 Nm / 37.5 ft.lb
M8 FIXINGS = 25.3 Nm / 18.6 ft.lb
