B. When steering wheel is released, steering control should return to the
neutral position with no additional turning.
4. If either of these performance tests indicate a steering problem, determine if

A. Park the machine on a level surface with the cutting units lowered, PTO
switch in the disable position, and the parking brake engaged.
B. With the engine running, turn the steering wheel to the left
(counterclockwise) until the steering cylinder rod is fully extended and
turn the engine off.
C. Read Precautions for Hydraulic Testing (page
D. Remove the hydraulic hose from the fitting on the rod end of the steering
cylinder. Plug the end of the hose removed.
E. With the engine off, continue turning the steering wheel to the left
(counterclockwise) with the steering cylinder fully extended. Observe the
open fitting on the steering cylinder as the wheel is turned. If hydraulic
fluid comes out of the fitting while turning the steering wheel to the left, the
steering cylinder has internal leakage and must be repaired or replaced.
F. Remove plug from the hydraulic hose and reconnect the hose.
5. If steering problem exists and steering cylinder passed test, perform the
Steering/Lift/Sidewinder Circuit Testing − Gear Pump (P2) Flow Test (page
5–55) and Steering/Lift/Sidewinder Circuit Testing − Relief Valve Pressure
Test (page 5–58) to make sure that the steering control valve and cylinder
are receiving adequate fluid flow and pressure. Based on the results of these
tests, repair or replace steering control valve as necessary (see
