Center Cut Mower

Necessity is the mother of invention, as they say, and old used things aren’t necessarily cliché. That was my epiphany when I ended my search for a center-cut horse-drawn sickle-mower.
My foray into animal-powered agriculture began with a bred heifer and a bit of sentimentality. You see, my first calf ever was a bull, and who wants to send their first calf to the butcher? The solution to this dilema was a bit of education, on both my part and the bull’s, and a yoke. I was on my way to training an ox.
With ox-power on the horizon, I began looking for tasks on the farm suitable for animal power, and one of the most attractive seemed to be mowing. I caught sight of a couple of youtube videos featuring horse powered haymowers, and I was mesmerized by the pleasing hypnotic song of the sickle-bar mower, clipping through the grass to the hoof-beat of biological power. The desire to play this song, myself, led me to purchase an old rusty John Deere mower, and Lynn Miller’s Horse-Drawn Mower book. I learned that, with some work, my new-old mower could cut grass with more elegance than any modern fossil-fuel-powered appliance.
The prospect of clipping pastures and cutting hay with the mower was satisfying, but I wondered how I might take advantage of a sickle mower in my primary crop of grapes. The problem is, my grape rows are about 9 feet apart, and the haymower is well over 10 feet wide. The Horse-Drawn Mower book hinted at the solution; the center-cut haymower, but an internet search quickly proved the obscurity of such machines, and an antique center-cut mower would be hard to find. Surely there must be existing technologies to address my situation. Hours of searching revealed a prototype center-cut mower on the opposite coast, in Oregon, or the slim possibility of adapting a motorized walk-behind mower to ground-drive. With the prospect of lots of trial and error in assembling something nearly from scratch, I decided to reexamine the past, as many of us do in our unconventional agricultural pursuits.
The John Deere and McCormick Deering mowers have served us well through the decades, and proved their durability. Is it possible to adapt this proven technology rather than tinker with untested modern stand-ins? A couple of mental models and a sketch were enough to decide it was worth a try. With a second mower to experiment with, I set off with the task of reversing the bar and guards to lay across the front path of the machine’s wheels. The following is a detailed documentation of how the conversion was completed.
