5.1.24 Check battery charge: (Electric start units only)
Service Interval: Monthly
Allowing batteries to stand for an extended period of time without recharging
them will result in reduced performance and service life. To preserve optimum
battery performance and life, recharge batteries in storage when the open
circuit voltage drops to 12.4 volts.
Note: To prevent damage due to freezing, battery should be fully charged
before putting away for winter storage.
a) Check the voltage of the battery with a digital voltmeter. Locate the
voltage reading of the battery in the table below and charge the battery for
the recommended time interval to bring the charge up to a full charge of
12.6 volts or greater.
IMPORTANT: Make sure the negative battery cables are disconnected
and the battery charger used for charging the battery has an output of 16
volts and 7 amps or less to avoid damaging the battery (see chart below for
recommended charger settings).

5.2 ADJUSTMENTS
5.2.1 Cutting height and anti-scalp roller adjustment.
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 and wait for all moving parts to stop.
b) Install hairpin clips in the holes for the desired cutting height (See Figure 9).
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 9).
2. The tire pressures are set as directed in Section 5.1.11.
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 ball
joint to the center of the furthest hole (See Figure 9).
