WARNING
POTENTIAL HAZARD
♦ When the two front support rod hairpins are removed
from the mower deck, the weight of the tractor section
may cause the front frame to rise suddenly
WHAT CAN HAPPEN
♦ If the unit rises suddenly, injury may occur.
HOW TO AVOID THE HAZARD
♦ Securely hold down the front of the unit when the front
support rod hairpins are removed.
a) Stop engine, wait for all moving parts to stop, and remove key or spark plug
wire(s).
b) Install hairpin clips in the holes shown on sketch below for the desired cutting
height (See Figure 13).
IMPORTANT: To maintain correct cutting height and rake, check the
following for proper adjustment.
1. The front and rear hairpins are in the same holes with the proper spacers
under the hair pins (See Figure 12).
2. The tire pressures are set as directed in Section 5.1.10.
3. The length of the rear deck support link assemblies should average 6.89”
(approximately 6 7/8”) (17.5 cm) from the center of the balljoint to the
center of the furthest hole (See Figure 12).
NOTE: All (4) pins must equally support the weight of the deck. Adjustment
in the length of the rear deck support assemblies may be necessary. If one
side of the frame is longer than 6.89” (17.5 cm), than the opposite side must
be shorter by the same amount.
