Section 6 R ADJUSTMENTS 6.1 Parking Brake Adjustment - NOTE If this procedure does not achieve proper brake adjustment, please contact your authorized Scag dealer. WARNING LOOSEN HERE Do not operate the mower if the parking brake is not operable. Possible severe injury could result. The parking brake linkage should be adjusted whenever the parking brake lever is placed in the “ENGAGE” position and the parking brake will allow the mower to move.
Section 6 R 6.2 Travel Adjustments LOOSEN HERE Neutral or tracking adjustments will need to be made if: A. The steering control levers are in the neutral position and the machine creeps forward or backward. See Neutral Adjustment on page 25 (next procedure). B. The steering control levers are in the full forward position and the mower pulls to one side or the other when traveling in a forward direction. See Tracking Adjustment on page 26. ADJUST HERE Neutral Adjustment STT99RHCRA Figure 6-3.
Section 6 R - NOTE - 6. Actuate the steering control levers forward and reverse several times and return them to the neutral position. If after making the adjustment as outlined in step 1A, the machine creeps forward or backward, perform the neutral adjustment. See Neutral Adjustment on page 25. 7. Check that the drive wheels remained in neutral and readjust if necessary. 8. Check that the steering control levers hit the stop before the pumps reach full stroke. Adjust as needed. 2.
Section 6 R 6.5 Belt Alignment 2. Loosen the two (2) elastic stop nuts. Adjust the bolt up or down on the adjustment bracket to adjust the cutter deck until the distance from the bottom of the cutter deck to the floor is the same as the measurement on the RH side of the machine. Belt alignment is important for proper performance of your Scag mower. If you experience frequent belt wear or breakage, see your authorized Scag service center for belt adjustment. 3.
Section 6 R - NOTE To prevent the cutter deck from teetering, all four (4) cutter deck hanging chains must have tension on them. If all four chains do not have tension on them and the deck teeters, you must readjust the cutter deck as outlined in the procedures above. All measurements should be taken from the top edge of the deck as the Velocity Plus decks have an uneven bottom edge.
Section 6 R C. 4-3/4" or 5-1/4" Position - (See Figure 6-9). Placing the baffle in either the 4-3/4" or 5-1/4" setting will enhance fall cutting (leaf pickup) and reduce cutter deck "blowout". To adjust the Custom-Cut Baffle height: 1. Place the cutter deck in the transport position. 2. Remove the hardware securing the Custom-Cut Baffle to the cutter deck. - NOTE Hardware location used in the illustrations are for reference only. Location of hardware may vary depending on cutter deck size. 3.
Section 6 R 6.8 electric clutch adjustment ADJUSTMENT NUTS The electric clutch serves two functions in the operation of the mower. In addition to starting and stopping the power flow to the cutter blades, the clutch also acts as a brake to assist in stopping blade rotation when the PTO is switched off or the operator presence circuit is interrupted. When the clutch is disengaged, the air gap between the armature and rotor must be adjusted to fifteen thousandths of an inch, 0.015, for proper operation.
