2. Remove Filler Cap. Remove Filler cap only when ready to fill hydraulic Tank with Oil. Do Not leave the Cap off and the system Open, always keep system closed when possible. Avoid any oil contamination. (See Figure 29) 3. Avoid Hydraulic Contamination by filtering the Hydraulic Oil while filling the Hydraulic Tank. Filter bug- gies or carts are commercially available for Hydraulic system cleanup and Oil transfer. These consist of high capacity filter, a Circulating Pump, a Drive Motor and hoses for connecting to the units hydraulic system. When adding Oil always use Clean new Oil from a sealed container, If you suspect the Oil of being contaminated don't use it. (See Figure 30 & 31). It is best to always use a filter system when adding even new oil. 4. When adding Oil in the field keeping it clean is critical, do not use dirty funnels or hoses. Do Not open Hydraulic tank or any containers unless the openings have been cleaned first. The outside of the containers must be clean. If a windy dusty day do not fill and allow dirt to blow into oil. Always add Oil using a pump system with at least a 10 Micron filter system. (See Figure 32) Figure 29 Figure 31 Figure 32 Figure 30 Fill Hydraulic Tank Fill Hydraulic Tank with Oil: 1. DO NOT START TRACTOR until you have filled Hydraulic Oil Tank to a level as shown in Sight Glass gauge and fill the Suction Hose to Pump with Oil. 2. Remove Filler Cap.

Fill Hydraulic Tank Fill Hydraulic Tank with Oil: 5. Fill Tank. Fill the Hydraulic Tank (See Figure 35) Fill tank till the Oil is visible in the sight Gauge (See Figure 33 & 34). This will fill tank for the start but it will have to filled again later. Read Step 6 a must. 6. Fill Suction Hose with Oil. This is an important step that must be done. Remove the Suction Hose at the Tank (See Figure 6) and fill the hose with clean oil, THIS IS A MUST DO. The Suction Hose must be filled with Oil to prevent Dry start up of Pump. Dry start up of PUMP can damage the Pump. After filling suction Hose reinstall it and tighten down Hose Clamp.

MOTOR - PUMP ELECTRICAL CIRCUIT Electrical Circuit: RH Wing Mower The electrical circuit is a pre-assembled wire harness that will control the motor functions. The harness will be used with a push pull off/on switch that prevents the tractor from being started when motor is engaged. The wire harness uses a three position toggle switch that is used to reverse the knife bar direction of travel. These switches are not part of the wire harness assembly, These switches must be connected correctly to operate correctly (See Figure 1). There is a motor control valve mounted on top of the hydraulic tank that will have two electrical solenoids connected to it. The wire harness has two plugs on one end that connects to the solenoids, one plug will have longer wire (also has White Wire) than the other and will connect to the solenoid further most from the cutter bar mount. The other plug with the shorter wire (has Yellow Wire) will connect to the first solenoid closet to the operator. IMPORTANT NOTICE, READ: The Starter solenoid wires and the 12V power supply wire must be connected to tractor wiring, The power source wire must be connected to a pow...
