cleanliness and tightness of the 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 the starting motor or alternator
should be performed by trained technicians only.
Access to Engine and Hydraulic
Pumps
The hydraulic pumps are accessed by lifting the seat
platform. The seat platform is hinged at the front. To raise
it, release seat latch and tilt seat platform up and forward.
The seat platform catch (See Figure 4-4) will prevent the
seat from going all the way over. However, if more access
is desired under the seat platform, the seat platform catch
can be raised allowing the seat to pivot more. Make
certain to place the control arms in the park brake position
and lift the seat arms before raising the seat.

WARNING!
Always wear adequate eye protection when servicing the
hydraulic system and battery.

WARNING!
Hydraulic oil escaping under pressure can penetrate skin.
Hydraulic oil may cause infection in a minor cut or opening in
the skin. If exposed to hydraulic fluid, see a doctor at once.
Before applying pressure to hydraulic system, make sure all
connections are tight and all hoses and lines are in good
condition. To find a leak under pressure, use a piece of
cardboard or wood, never use your hands. Relieve all pressure
in the system before disconnecting or working on hydraulic
lines. To relieve pressure, place control levers in park.
The 1.0 U.S. gallon (3.79 liter) hydraulic reservoir is
located in front of the engine and under the operator’s
platform. See Figure 4-5.
Check oil level in hydraulic system after every 50 hours of
operation or weekly, whichever occurs first. Check more
often if system appears to be leaking or otherwise
malfunctioning.
Fluid level should be 1” from top of reservoir. Use only
SAE 10W40 SG, SF/CC, CD service motor oil.
Change hydraulic system filter element (Land Pride P/N
831-030C) (Fig. 4-5) after first 50 hours of mower
operation, then replace filter and oil in reservoir every 500
hours thereafter. When changing hydraulic oil use 1/2 unit
(approximately 3.5 oz.) of Lubrizol additive (Land Pride
P/N 821-041C). This additive, available from your Land
Pride dealer, will increase the performance life of the
hydraulic system components.
The system filter is located directly in front of the hydraulic
reservoir. A standard oil filter wrench is used to change
filter, threads are right handed. Use an Accu Z approved
filter element only (Land Pride P/N 831-030C).

IMPORTANT: Never use hydraulic or automatic
transmission fluid in this system; use only motor oil as
specified. Remember, dirt is the primary enemy of any
hydraulic system.

IMPORTANT: Pre-fill the filter element with clean oil,
before installing, to prevent drawing air into the system
pump.
