The Ezee-On 6000 Series Floating Hitch Multi-Purpose Cultivator is a robust agricultural implement designed for various tillage operations. This owner's manual provides comprehensive information on its operation, maintenance, and safety procedures.
Function Description:
The Ezee-On 6000 Series Cultivator is engineered for multi-purpose tillage, featuring a floating hitch design that allows for optimal ground contour following and consistent depth control. It is equipped with a series of shanks that penetrate the soil, breaking it up and preparing the seedbed. The floating hitch mechanism ensures that the cultivator maintains a uniform working depth across uneven terrain, which is crucial for effective soil preparation and crop establishment. The cultivator can be equipped with different shank trip forces (350 lb or 550 lb) and various shank spacings (8", 10", or 12") to suit different soil conditions and desired tillage intensities. It also incorporates hydraulic lift cylinders for raising and lowering the machine, as well as for adjusting the cutting depth. The design allows for the attachment of additional equipment behind the cultivator, such as air seeders, provided the hitch is properly configured to maintain a balanced line of draft.

- Hydraulic Cylinders:
- Centre Frame: Rephasing, 2 units, 4" x 8" (101.6mm x 203.2mm).

- Outer Wing: Non-Rephasing, 2 units, 4" x 36" (101.6mm x 914.4mm).
- Bolt Torque Specifications:
- Shank Assembly U-Bolt (5/8" x 4"): 150 ft. lbs. (203 N.m).
- Shank Pivot Bolt (3/4"): 265 ft. lbs. (359 N.m).
- Rockshaft Linkage Bolts (1-1/4"): 840 ft. lbs. (1139 N.m).
- Wheel Bolts (9/16"): 130 ft. lbs. (176 N.m).
- Stub Extension U-Bolt (5/8" x 4"): 150 ft. lbs. (203 N.m).
Usage Features:
- Floating Hitch: Ensures consistent cutting depth by allowing the cultivator to follow ground contours independently of the tractor.
- Hydraulic Depth Control: Utilizes a flow valve system to precisely set and adjust the cutting depth. The valve actuator makes contact with a valve piston to stop oil flow, with depth adjusted by the actuator's position.
- Mechanical Depth Control: Achieved by installing segments (1/2" to 2" or 12.7mm to 50.8mm) on the rockshaft cylinder shafts. All cylinders must have the same total length of depth control segments for even depth.
- Wing Lift Cylinders: Allow for raising and lowering of inner and outer wing frames, with adjustments made via cylinder anchor bolts to level the machine.
- Front-to-Rear Leveling: Adjusted by changing the height of the castor wheel at the front of the wing and centre frames, typically by lengthening or shortening the push link assembly.
- Rephasing Rockshaft Cylinders: A procedure to re-synchronize hydraulic lift cylinders on inner and outer wings with the centre frame cylinders, ensuring even cutting depth. This involves fully extending all rockshaft cylinders by holding the hydraulic control lever until oil flows through bypass ports.
- Transport Safety: Includes provisions for installing an SMV (Slow Moving Vehicle) emblem and warning lights, attaching a safety chain to the tractor drawbar, and locking wings in the folded position with transport locks. Hydraulic lockout valves are used to secure the cultivator in a raised position during transport.
- Towing Equipment: The cultivator can tow additional equipment, but the towed equipment's hitch must be attached low enough to create a 5-degree downward slope towards the cultivator for a balanced line of draft.
Maintenance Features:
- Lubrication:
- Grease Points (G-arrows):
- Rockshaft Bearings: Every 20 hours.
- Wheel Bearings: Every 50 hours.
- Castor Wheels (6 pivot points): Every 50 hours.
- Walking Beams (pivot bearings): Every 50 hours.
- Push Arm Assembly (cross tube): Every 100 hours.
- Oil Points (O-arrows):
- Hinge Bolts: Every 100 hours.
- Push Arm Threaded Shaft: Beginning of each season.
- Rockshaft Arm Ball Joints: Beginning of each season.
- Rockshaft Cylinder Pins: Every 50 hours.
- Bolt Tightness Checks: All bolts and nuts, especially 3/4" (19.0mm) shank assembly pivot bolts and 1-1/4" (31.1mm) rockshaft linkage bolts, should be checked periodically for tightness to prevent wear and damage.
- Tire Maintenance: Maintain correct air pressure in all tires and regularly check for nicks, cuts, and abrasions.
- Hydraulic System Care:
- Always relieve pressure in the hydraulic system when not operating or servicing the cultivator.
- Periodically check hydraulic hoses for ruptures and leaks. Use wood or cardboard as a backstop and wear gloves/eye protection when searching for leaks.
- Ensure all hydraulic cylinders are completely filled with fluid to prevent wing free-fall or sudden movement.
- Decal Maintenance: Keep all safety decals clean and legible, replacing any that are destroyed, missing, or illegible.
- Storage: At the end of the season, relieve hydraulic pressure, disconnect and cap hoses, cover cylinders and hoses, coat exposed cylinder shafts with grease, set planks under each wheel, lubricate all grease points, and inspect for worn/damaged parts.
- Troubleshooting Guide: The manual includes a comprehensive troubleshooting section to address common issues such as uneven cutting depth, machine skewing, or hydraulic system malfunctions, providing possible causes and remedies.
