Going High Tech


Hay slings laid out in the loft for evaluation.
It's been hot this week... mid 80's with humidity to match. It makes my t-shirt stick to my skin and ride up up under my overalls like an unfortunate halter top. Daily rain is nice for the orchard and garden, not so nice for the weeds which can't be knocked back without a little drying time. The animals all retreat to the barn as soon as the sun is up, where they spend the day avoiding the biting flies whose populations seem to rise exponentially with the temperature. The horses stomp constantly to keep the flies off, and the cows all stand sweating and panting like dogs. The still barn air feels about 10 degrees hotter than the air outside, and reeks of ammonia. The stone foundation is dripping with condensation. Horseflies cover the windows, apparently regretting their decision to follow the animals inside the darkened retreat.

The barn that seemed so well maintained suddenly feels impossible, as the animals deposit all the end products of their night-time grazing indoors on expensive bedding. Keeping up with them feels like mopping up underneath a waterfall. I'm scooping out four heaping wheelbarrow loads a day, but it probably needs to be closer to eight (if there were no backlog, that is).

Weather like this always makes me think of moving back to a cool maritime climate. This year I'm dreaming of Sitka, where this week's highs look to be right around 60 degrees. Last year it was Waldron Island in the San Juans, and the year before that it was Lopez Island. Though wonderfully cool by comparison to our Michigan summer, each location seems to be somewhat lacking in gainful employment opportunities and affordable land. Suffice it to say that I'm really hoping things cool down in time for our second cutting of hay in mid July.

With the construction of our new barn, putting up hay has become a little easier. It would've been considered high tech, circa 1910 -- as evidenced by the patent date on the hay trolley. In the absence of diesel, it will again be high-tech. As far as I'm concerned, it's the best way to put up hay without the direct use of fossil fuels, bar none.

The high technology of our new operation revolves around the use of hay slings, rather than the grapple forks used in our original barn. Hay slings look much like hammocks, which are laid out on the wagon as the hay is loaded, typically three of them sandwiched into the layers on a full load.

For unloading the hay from the wagon, we lower the hay rope with its two hooks on pulleys, each of which attach to a ring at opposite ends of the slings. The horses then pull the rope, which rolls up the hay (each load looks like a large round bale) and raises it to the roof peak. Control lines are rigged to pull the trolley to either mow, where a release cord is pulled, allowing the sling to split in two and release the hay.

What's so good about slings? The biggest advantage is that the wagon can be unloaded in three "bites" rather than the 5 or 6 it typically takes with grapple forks. It's also much easier to attach the slings to the hay rope than it is to set the grapple forks for each bite.  For us, the design of the new barn, with its drive-through center aisle, is easier to use than the bank barn we've been using. The bank barn forced us to park the horses, unhitch the wagon, and roll it in (and out) by hand.

The down side?  Hay slings will load the barn's hay trolley system quite a bit more than other methods, which is why our old barn only gets to use grapple forks. They're also a little more trouble to arrange and keep organized out in the field, as we need to pause to set up the second and third slings partway through each load.

So while the new barn isn't quite finished (it still needs a floor, gutters, stalls, and some paint), we're already making good use of it. Now we just need to get it ready for the animals that will eat the hay.
