Install the Weight Plates
All units SN 599,999 and Lower and Liquid
Cooled XS units SN 600,000 and Higher only.
Weight plates not required for air cooled units
SN 600,000 and Higher.
1. The four weight plates (Item 33) must be installed
under the front panel of the floor pan. These
weights give proper balance to the machine when
the removable portions of the bagger are
removed.
Units below SN 600,000 with the 2 post foldable
ROPS installed require additional mounting plates
(Item 42) and a front weight (Item 41) to be
installed. The front weight is removable and
retained by using hairpins (Item 43).
Units SN 439,999 and Lower:
2. Locate the position of the mounting holes. Clamp a
weight plate to the front of the floor pan (See Figure
17). The ears on the weight plate should be
towards the bottom (upside down from the actual
Drill holes here
mounted position). Align the bottom edge of the
weight plate with the bottom edge of the floor
pan front panel. Center the weight plate side to
side. Mark the position of all four holes using a
center punch.
3. Drill 3/8 inch holes at the points marked.
For units 439,999 and Lower without a ROPS
installed:
4. Install the four weight plates behind the front
panel using the 5/16-18 x 1.50 screws, 5/16
washers and 5/16-18 whizlock nuts (Items 34,
35, and 36). The weight plates will only fit
with the ears located near the bend in the floor
pan (See Figure 18). The decal on the
outside of the floor pan will still be visible with
the weight plates mounted.
