Operator Controlled Discharge Chute Models: OPERATOR’S MANUAL SCZ/STC-OCDC-48V SCZ/STC-OCDC-52V STC-OCDC-61V STT-OCDC-52V SCZ/STT-OCDC-61V SVR-OCDC-48V SVR-OCDC-52V SVR-OCDC-61V This manual contains the operating instructions, assembly instructions and safety information for your Scag accessory. Reading this manual can provide you with assistance in operation and installation procedures to keep your accessory performing to maximum efficiency.
WARNING FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT IN SERIOUS INJURY OR DEATH. • Read this manual completely as well as other manuals that came with your mower. • DO NOT operate on steep slopes. To check a slope, attempt to back up it (with the cutter deck down). If the machine can back up the slope without the wheels slipping, reduce speed and use extreme caution. • Under no circumstances should the machine be operated on slopes greater than 15 degrees (20 degrees for SVR).

Section 1 R GENERAL INFORMATION 1.1 Introduction 1.2 Direction Reference Your OCDC was built to the highest standards in the industry. However, the prolonged life and maximum efficiency of your OCDC depends on you following the installation and operation instructions in this manual. The “Right” and “Left”, “Front” and “Rear” of the machine are referenced from the operator’s right and left when seated in the normal operating position and facing the forward travel direction.
Section 1 R 1.
Section 2 R SAFETY INFORMATION 2.1 Introduction Danger Your mower is only as safe as the operator. Carelessness or operator error may result in serious bodily injury or death. Hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper training of the personnel involved in the operation, transport, maintenance and storage of the equipment. Make sure every operator is properly trained and thoroughly familiar with all of the controls before operating the mower.
Section 2 R 2.4 OCDC Operation 2. When using any attachment, never direct the discharge of material toward bystanders or allow anyone near the machine while in operation. The OCDC (Operator Controlled Discharge Chute) can be raised or lowered to side discharge or block the discharge of grass clippings. Follow the steps below for proper operation of the OCDC. 3.
Section 2 R OPEN POSITION In the open position, the clippings will side discharge. 1. Rotate OCDC control handle outward to lower the side discharge chute. See Figure 2-2. The discharge chute will lower to it's original position for safe sidedischarge operation. Figure 2-2.
