Hydraulic System Test Ports
Use the h y draulic system test por ts to test the

local T oro distributor for assistance .
Use T est P or t #1 ( Figure 73 ) to assist in
troubleshooting the h y draulic circuit for the front
cutting units and lift cylinders .
Use T est P or t #2 ( Figure 73 ) to assist in
troubleshooting the h y draulic circuit for the rear
cutting units .
Use T est P or t #3 (not sho wn—located on the rear
