• • • • Disengage the PTO, stop the engine and wait until the tiller comes to a complete stop before making any repairs, adjustments, or removing any rocks or debris. Use extra caution when loading or unloading the machine into a trailer or truck. A tractor with a tiller attachment should not be driven up or down a ramp onto a trailer or truck under power, the unit could tip over causing serious personal injury. The unit must be pushed manually to load or unload properly.
• • • • • • • Never remove gas cap or add fuel while the engine is hot or running. Allow engine to cool at least two minutes before refueling. Never over fill fuel tank. Fill tank to no more than ½ inch below bottom of filler neck to provide space for fuel expansion. Replace gasoline cap and tighten securely. If gasoline is spilled, wipe it off the engine and equipment. Move unit to another area. Wait 5 minutes before starting the engine.
SECTION 2: SLOPE GAUGE 10° FOLD ON A POWER POLE A CORNER OF A BUILDING OR A FENCE POST PE SIGHT AND HOLD THIS LEVEL WITH A VERTICAL TREE DOTT E D LIN E , R E PRES ENT I N G A 10° SL O WARNING Do not use the tiller attachment and tractor on inclines with a slope in excess of 10 degrees (a rise of approximately 2 feet every 10 feet). A riding mower could overturn and cause serious injury. Operate RIDING mowers up and down slopes, never across the face of slopes.
SECTION 3: TO THE OWNER Model OEM-190-825 hydraulic tiller attachment is designed for use on FastAttach compatible Garden Tractors only. It will NOT fit nor operate properly or safely on ANY other tractor. It will NOT fit nor operate properly or safely on FastAttach compatible Lawn Tractors. The use of OEM-190-825 hydraulic tiller attachment on FastAttach compatible Lawn Tractors will void the tractor’s warranty as to resulting damages.
SECTION 5: ASSEMBLING THE TILLER Attaching the Hydraulic Hoses Small Diameter Hose Fitting Two hydraulic hoses are packaged separately in the carton. Both hoses have female connectors on either end and will attach to male connectors on both the hydraulic pump assembly (found on the underside of the undercarriage assembly) and the tiller assembly itself.
SECTION 6: PREPARING THE TRACTOR NOTE: References to LEFT and RIGHT indicate the left and right sides of the tractor and/or the tiller attachment from the operator’s position in the tractor’s seat. WARNING: Before beginning installation, place the tractor on a firm and level surface. Place the PTO in the disengaged (OFF) position, stop the tractor engine and set the parking brake. IMPORTANT: The use of this tiller attachment requires the use of the weight bracket and three 45 lb.
Tiller Tiller Assembly Tiller Stand Large Diameter Hydraulic Hose Hairpin Clips IMPORTANT: If your tractor is equipped with an electric PTO, remove this keeper pin prior to mounting the undercarriage assembly.
• Repeat the previous step on the rear of the undercarriage assembly. Tiller Assembly Note how the electric sleeve hitch cylinder shaft is attached to the sleeve hitch U-bracket (refer to Figure 7 & Figure 8) before proceeding on to the first step below. Upon completing the following steps, the tiller assembly will be attached to the sleeve hitch cylinder shaft in the exact same manner.
IMPORTANT:Before proceeding to the next step, make certain that both the large diameter hose and the small diameter hose are routed to the INSIDE of both hitch latches as illustrated in Figure 10 & Figure 11. Failure to properly route the hoses may cause the tractor tire coming in constant contact with a hydraulic hose, resulting in premature wear.
SECTION 8: KNOW THE TILLER Dipstick/Reservoir Cap Hydraulic Reservoir Tine Direction Lever Hydraulic Filter Drain Plug Hydraulic Control Valve Tiller Stand (Lowered Position) Hydraulic Motor Tiller Tines Figure 13 Tine Direction Lever The tine direction lever is located on the top of the tiller attachment on the right side of the unit. See Figure 13. This lever is used to control which direction the tines turn.
Hydraulic Reservoir • The hydraulic reservoir is a part of the tiller frame and can be filled by removing the dipstick/reservoir cap located directly on top of the tiller in the center. The dipstick/reservoir cap is vented to allow for expansion of the hydraulic fluid as it heats up during normal use. Pull the hairpin clip which secures the clevis pin to the tiller stand. See Figure 15. Hairpin Clip IMPORTANT: Always maintain the correct level of fluid in the reservoir.
• • • • • Tilling Depth Apply the tractor’s parking brake to stabilize your position. Make certain the tiller stand is in the fully raised (Operating) position. See Figure 13 and Figure 15. Place the tractor’s throttle in the FAST (Rabbit) position) Place the tiller attachment’s tine direction lever in either the Forward or Reverse position. Place the tractor’s PTO in the engaged (ON) position.
Operating Tips • • Stop the tractor’s forward motion. Raise the tiller out of the ground using the toggle switch installed as part of OEM-190-824. • Place the tine direction lever in position so that the tines will spin in the opposite direction that they were spinning when the tilling motion stopped (i.e. If the tiller was in the forward (F) position when it stopped, shift into the reverse (R) position). • Place the tractor’s PTO in the engaged (ON) position.
• • • The entire area around both the hitch latches. The entire area around both the upper support rod and lower support rod on the electric lift cylinder. All clevis pins and hairpin clips on both the tiller attachment and the electric sleeve hitch attachment. • Thread the dipstick/reservoir cap back onto the hydraulic reservoir before removing it again to check the level of the fluid level on the dipstick. Add hydraulic fluid as necessary. See Figure 17.
• • Reinstall the drain plug and tighten securely. Place the tiller attachment back to a level position and lower the tiller stand to support it. • Remove the dipstick/reservoir cap from the hydraulic fluid reservoir and carefully pour in four gallons of hydraulic fluid.
