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 charging
system should be performed by trained technicians only.
Hydrostatic Drive System
!
DANGER
Hydraulic fluid under pressure can penetrate skin. Wear
protective gloves and safety glasses or goggles when working
with hydraulic systems. Use a piece of cardboard or wood
rather than hands when searching for hydraulic leaks. If
hydraulic fluid is injected into the skin, it must be treated by a
doctor within a few hours or gangrene may result.
!
WARNING
Always wear adequate eye protection when servicing the
hydraulic system.
The Accu-Z is equipped with two completely
independent hydrostatic drive systems with each system
consisting of a reservoir, pump and motor.
Access the hydrostatic drive units by lifting the seat
platform which is hinged at the front. To raise the seat,
pull on the seat release latch at the back and tilt the seat
platform up and forward.
Repairs to the hydraulic pumps and motors should be
performed by trained technicians only.
The hydrostatic drive pumps are equipped with bypass
valves that must be opened before moving the mower with
a stalled engine. Refer to “Moving Mower with Stalled
Engine” on page 18 for more information.

IMPORTANT: Do not use a high pressure washer
on or around the hydraulic pumps and motors. Water
intrusion will result and void the warranty.
Hydraulic Oil Level Check
Refer to Figure 5-8:
Hot oil expands, therefore, check hydraulic oil level only
when it is cold. The left side is independent from the right
side. Make sure you check and fill oil as needed on both
sides. Oil level should be between the two cold arrows
located on the reservoirs. Add hydraulic oil to the
reservoir if below the bottom arrow. Do not fill above the
top arrow. See page 52 for hydraulic oil specifications.

Hydraulic Oil and Filter Change
Refer to Figure 5-11 on page 40:
Each hydraulic pump has its own independent oil
system. Therefore, each pump will require new hydraulic
oil and oil filter. It is best to change oil soon after using
the mower while dirt particles are still suspended in the
oil. See page 52 for hydraulic oil specifications.
Initially, change hydraulic oil and oil filters after the first
25 to 50 hours of operation. Thereafter, change hydraulic
oil and filters every 500 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. 810-590C.
Refer to Figure 5-9, Figure 5-10 & Figure 5-11:
1. Place an oil pan beneath drain plug (#1) on the left
side and remove drain plug.
2. Remove fill cap (#5) from the left oil expansion tank.
Allow all oil to be drained from expansion tank before
proceeding to step 10.
3. To facilitate drainage, remove the left reservoir cover
(#2) and fill plug (#3).
4. Remove the left side oil filter (#6) and properly
discard.
