History and Development of the John Deere No. 9 Sickle Mower
Origins of John Deere Mowing Equipment
John Deere, founded in 1837, quickly established a reputation for manufacturing high-quality farm implements. By the early 1900s, Deere expanded into mowing machinery, aiming to provide farmers with efficient alternatives to manual hay harvesting. The company's first successful mowing machines were reel-type mowers, but as technology advanced, sickle bar mowers became increasingly popular due to their simplicity and effectiveness.
Introduction of the No. 9 Model
The John Deere No. 9 sickle mower was introduced around the 1920s as part of Deere's effort to improve mowing efficiency. It was designed to be mounted on various tractors, making it adaptable for different farm sizes and needs. The No. 9 quickly gained popularity for its sturdy construction, ease of operation, and maintenance-friendly design.
Significance in Agricultural History
The No. 9 represented a significant step forward in mechanical hay harvesting. Its design allowed for more extensive acreage to be mowed in less time, reducing the labor costs and physical strain associated with manual methods. It also contributed to the mechanization of small and medium-sized farms, setting the stage for future innovations in agricultural machinery.

Design and Construction of the John Deere No. 9 Sickle Mower
Overall Structure and Components
The John Deere No. 9 sickle mower comprises several key components that work together to perform efficient mowing:
- Sickle Bar: The central cutting mechanism, featuring a series of reciprocating blades that cut the grass or hay.
- Frame: Robust steel structure supporting all components, designed to withstand tough field conditions.
- Drive Mechanism: Usually powered by the tractor's PTO (Power Take-Off), transmitting power to the sickle bar.
- Guarding and Safety Features: Protective shields and guards to prevent debris from flying out and to ensure operator safety.
- Transport Wheels and Hitch: For maneuvering and attaching the mower securely to a compatible tractor.
Key Design Features
- Sickle Bar Lengths: Typically ranging from 5 to 9 feet, allowing for efficient coverage depending on the model variant.
- Reciprocating Blades: Arranged in a series, these blades move back and forth at high speeds to provide a clean cut.
- Quick-Change Knives: Some models feature blades that can be replaced or sharpened easily, minimizing downtime.
- Adjustable Cutting Height: Enables operators to set the mower for different crop heights and conditions.
Materials Used
The No. 9 was built primarily from durable steels, ensuring longevity and resistance to wear. The blades were often made from hardened steel for sharpness and durability, while the frame components were robust to endure field stresses.

Operation of the John Deere No. 9 Sickle Mower
Preparing the Equipment for Mowing
Before operation, it is essential to:
- Inspect the mower for any damage or loose parts.
- Sharpen or replace blades if necessary.
- Ensure all safety guards are in place.
- Attach the mower securely to the tractor's hitch.
- Connect the drive mechanism to the tractor's PTO shaft.
Mowing Procedure
1. Adjust the Cutting Height: Set the desired height to match crop conditions.
2. Engage the PTO: Start the tractor and engage the PTO to power the sickle bar.
3. Begin Mowing: Move at a steady speed, ensuring consistent coverage.
4. Monitor the Equipment: Watch for any irregularities such as blade jams or uneven cuts.
5. Disengage and Park: After completing the task, disengage the PTO, detach the mower, and perform a post-operation inspection.
Best Practices for Efficient Use
- Maintain a steady, moderate speed to prevent blade damage.
- Regularly check and tighten bolts and connection points.
- Keep blades sharp for clean cuts and reduced strain on the machine.
- Avoid mowing in overly wet or muddy conditions to prevent soil and debris from damaging the blades.
