Jackson Baileys Horse-Powered Hay Baling Crew

 

Great-granddad’s horse-powered hay baling crew using a machine known as a mule-power press or a sweep baler.

My theory about Grandma driving the buggy with lunch is incredibly likely—women frequently drove lighter buggy teams to the fields to bring the massive "threshing and baling dinners" to the workers.

Here is exactly what is happening in these three photos and how that unique lever machine worked:

1. The Machine: The Sweep Power Press

The machine with the swinging lever arm is a horse-powered hay press.

• How it worked: Instead of an engine, this machine used the physical walking power of the horses. One team of draft horses was hitched to a long wooden sweep arm (the lever arm you see).
• The Circle: The horses walked in a continuous, tight circle around the machine. As they walked, the arm rotated, turning gears that operated a heavy mechanical plunger inside the baler's chamber.
• The Compression: Men on foot would use pitchforks to pitch loose hay from that massive pile into the hopper. Every time the horses completed a rotation, the plunger slammed forward, compressing the loose hay into a tight block.

2. The Idle Team: "Switching the Power"

Seeing one pair of draft horses standing idle explains how the crew kept the operation moving all day.

• Walking in a tight, repetitive circle while pulling a heavy mechanical load was incredibly exhausting for horses. It could make them dizzy and worn out quickly.
• To prevent injury and exhaustion, baling crews kept a second team standing by in the shade or resting. Every hour or two, they would unhitch the working team and swap in the fresh, idle team.

3. Tying the Bales: A Two-Man Job

Just out of view or deep in the mechanics of your photo, two men were likely working right at the mouth of that machine:

• As the machine compressed the hay, blocks of wood called "blocks" were dropped in to separate the bales.
• Wooden or metal wires were threaded through grooves in the blocks. Two workers (often younger boys or family members) had to quickly thread the wire by hand and tie it off to lock the bale together before the machine pushed it out.

4. Hay vs. Wheat: The Big Difference

The realization that this is hay baling and not wheat threshing is a great catch.

• Threshing wheat required a massive, loud machine to separate grain seeds from straw.
• Baling hay was about preserving food for the very horses you see in the photo. Loose hay took up too much room in a barn and rotted easily. Compressing it into tight bales allowed the farmers of Texas Ridge to stack it cleanly and store it to feed their draft teams through the long Idaho winter.
