4.
Recharge the battery before returning to
service. Although the tractor may start,
the engine charging system may not
fully recharge the battery.
Removing the Battery
1.
Flip the seat all the way forward.
2.
Unhook the strap (a) holding the battery in
place. See Figure 4-5.

(c)
Figure 4-5
3.
Remove the hex cap screw and sems nut
securing the negative cable grouping (b)
to the negative battery post (marked NEG).
Move the cable grouping away from the
negative battery post. See Figure 4-5.
4.
Remove the hex cap screw and sems nut
securing the positive cable grouping (c)
to the positive battery post (marked POS).
See Figure 4-5.
5.
Carefully lift the battery out of the tractor.
6.
Install the battery by repeating the
above steps in the reverse order.
Note: Place the thickest cable closest to
the battery terminal.
Using the Transmission Bypass Rods
If for any reason the tractor will not drive or you
wish to move the tractor, the two hydrostatic
transmissions are equipped with a bypass
rod that will allow you to manually move the
tractor short distances.
WARNING
Do not tow the tractor, even with the bypass rod engaged.
Serious transmission damage will result from doing so.
1.
Engage the transmission bypass valves
by pulling the bypass lever (a) upward
and all the way back. See Figure 4-6.

To release the bypass lever (a), push the

Hydrostatic Transmission (500 Series)
The hydrostatic transmission on the 500 series
is equipped with a filter and dipstick.
To check the transmission oil, locate the
dipstick on both the LH and RH transmission
assemblies. See Figure 4-7.
Full Hot
(b)
Full Cold
1/8" up dipstick
Remove the dipstick and check the oil level.
When cold, the level should be no higher
than 1/8" up on the dipstick. When hot the
level should not exceed the "H" mark on the
dipstick. Exceeding these levels could cause
the oil to overflow when hot. See Figure 4-7.
To change the transmission oil:
1.
Remove the dipstick.
2.
Place a suitable container under the
drain plug (a) on the transmission.
Remove the drain plug (a) and allow the
transmission oil to drain. See Figure 4-8.
3.
Using a pair of needle-nose pliers or a
magnet remove the filter.
4.
Replace the filter and drain plug
(torque to 115-135 in-lbs) and fill the
transmission assembly to 1/8" up on
the dipstick.
5.
Replace the dipstick.
Note: Make sure the dipstick is fully
tightened. If the dipstick is not fully
tightened, transmission oil could leak
and cause damage to the transmission
due to insufficient oil.

Hydrostatic Transmission (700 & 900 Series)
The 700 and 900 series are equipped with dual
integrated hydrostatic pumps/transaxles that
are equipped with a transmission oil expansion
reservoir. Under normal operating conditions,
the oil level in the expansion reservoir does
not need to be checked and no additional oil
is needed. If checking the reservoir oil level,
proceed as follows:
WARNING
Check the oil level ONLY before starting the tractor
when the transmission oil is fully cooled.
1.
Pivot the operator's seat forward and
clean the reservoir cap and the area
around the cap to prevent debris from
contaminating the transmission oil. See
Figure 4-9.
Figure 4-9
2.
Turn the reservoir cap counter-clockwise
to remove, then check the oil level in
the reservoir. Oil should be visible at the
bottom of the cup, but the oil level must
NOT be above the "FULL COLD" line. See
Figure 4-9. DO NOT FILL THE RESERVOIR.
3.
If necessary to add oil because of some
type of leakage, add only enough oil to
bring the level to the "FULL COLD" line.
Reinstall the cap and fully tighten.
Note: Prior to the initial operation of the
tractor, the oil level in the reservoir may
be slightly higher than the maximum
due to air in the oil lines. Operation of
the tractor will eventually purge the air
from the lines and the oil level will settle
to the maximum.
To change the transmission oil:
1.
Remove the cap from the transmission
oil expansion reservoir.
2.
Place a suitable container under the
drain plug (a) on the transmission.
Remove the drain plug (a) and allow the
transmission oil to drain. See Figure 4-10.
