Before attempting any diagnosis of electrical system,
use a test light or voltmeter to check battery voltage. If
battery voltage is satisfactory, check cleanliness and
tightness of terminals and ground connections. A
general understanding of electrical servicing and use of
basic test equipment is necessary for troubleshooting
and repair.
Major overhaul or repair of starting motor or alternator
should be performed by trained technicians only.

Transaxle Oil and Filter Change
The mower has two independent hydrostatic transaxle
systems. Each system will require separate oil and oil
filter changes. It is best to change oil soon after using the
mower while dirt particles are still suspended in the oil.
See page 43 for transaxle oil specifications.
Initially, change oil and oil filters after the first 25 to 50
hours of operation. Thereafter, change oil and filters
every 200 hours or every year whichever comes first.
Two filters are required with each oil change. They may
be purchased from your nearest Land Pride dealer. Ask
for filter Part No. 831-060C.
1. Park unit on a flat level surface. Stop engine and
remove ignition key. Make sure blade engagement
switch is in the down (OFF) position. Spread
control levers fully apart.
Refer to Figure 5-6 & Figure 5-7 on page 34:
2. Begin on the left side by placing an oil pan (12" or
more in diameter with approximately 8 qt. capacity)
beneath the transaxle oil filter.
3. Remove screws (#7) and filter guard (#6).
4. Remove hair pin cotter (#4), flat washer (#3) and
clevis pin (#1).
