This document is an operator's manual for the Buhler Ezee-On Model 3550 Cultivator and Model 5550 Chisel/Cultivator. It includes assembly, operation, and parts list instructions.
Function Description:
The Buhler Ezee-On Model 3550 Cultivator and Model 5550 Chisel/Cultivator are agricultural implements designed for soil cultivation. The manual outlines their use for preparing fields, with specific instructions for field operation, adjustments, and transportation. The cultivators feature a folding wing design for transport and a rockshaft system for depth control. The Model 3550 is a cultivator, while the Model 5550 is a chisel/cultivator, suggesting different primary tillage capabilities, with the chisel likely designed for deeper soil penetration.

Stroke Control Segments (Table III):
The manual includes a detailed table for stroke control segments (Grip-Rite, for Flat Head Cylinders ONLY), specifying various combinations of segment lengths (e.g., 2", 1-1/2", 1-1/4", 1", 3/4", 5/8") to achieve desired stop lengths ranging from 7-1/8" (181mm) down to 5/8" (15.7mm).
Usage Features:
- Hydraulic System: The implement uses a hydraulic system for lifting and lowering the main and wing frames. It features hydraulic lock-up valves to prevent accidental operation during transport.
- Levelling: Quick levellers are used to adjust wing frames relative to the center section. Castor wheel links allow for front-to-rear levelling.
- Depth Control: Cutting depth is controlled by installing segment collars on the rockshaft cylinder shaft, with various segment combinations available for precise adjustment.
- Shank Trip Assemblies: Springs on the shank trip assemblies are tightened to maintain the ground tool in the desired position, with different tension settings for Model 3550 (8 turns) and Model 5550 (10 turns).
- Transport: The wings fold up for transport and are secured with transport lock pins. An SMV (Slow Moving Vehicle) emblem and warning lights are required for public road transport. A safety chain must be attached between the cultivator hitch and the tractor drawbar.
- Towing Equipment: Instructions are provided for attaching towed equipment, emphasizing proper hitch height to ensure even shank penetration.
Maintenance Features:
- Lubrication:
- Grease Points (G): Rockshaft bearings (every 20 hours), wheel bearings (every 10 hours), castor wheel linkage pivot points (every 100 hours), walking beams pivot bearings (every 50 hours), and push arm assembly pivot points (every 100 hours).
- Oil Points (O): Hinge bolts (when dry), rockshaft link threaded shaft (when dry), rockshaft arm ball joints (at season start/end), push arm threaded shafts (when dry), and rockshaft cylinder pins (every 40 hours).
- Bolt Tightness: All bolts and nuts should be checked periodically for tightness, with special attention to shank trip assembly pivot bolts and ball joint linkage bolts on the rockshaft system.
- Tire Pressure: Check tire pressure every 100 hours and maintain equal pressure in all tires. Inspect tire tread for damage.
- Hydraulic System Maintenance: Always relieve pressure in the hydraulic system before servicing. Periodically check hydraulic hoses for ruptures and leaks. Ensure hydraulic cylinders are completely filled to prevent free-fall of wings.
- Bearing Replacement: Detailed instructions for replacing walking beam bearings, including checking wheel leg plate width and proper installation of cone bearings and machinery bushings.
- Castor Wheel Adjustment: Instructions for adjusting the center frame castor wheel's spring washers to prevent fishtailing during transport.
- Shank and Holder Assembly: Instructions for replacing nylon bushings in the shank and holder assembly if excess side movement occurs.
- Decals and Reflectors: Keep all decals clean and legible, and replace any damaged ones.
- Storage: Relieve hydraulic pressure, disconnect and cap hoses, clean and coat cultivator/shanks with rust preventative, cover cylinders/hoses, grease exposed cylinder shafts, place planks under wheels, lubricate all grease points and ball joint sockets, check for worn parts, and touch up paint.
