how hay is made


How hay is made!


  • Hay is made very carefully. There’s a surprising amount of science and engineering that goes into making hay, and now that I live in hay-making country I thought it prudent to learn more about how hay is made.

Of course, many factors contribute to the quality of hay.


  • You have the type of hay, the soil it’s grown in, how “weedy” the fields are, how much rain happens (or not), and how it’s turned from grass into bales of hay. When all of the stars align, your horse can munch down on some amazing hay.


First things first – the cutting of hay.


  • Basically, the hayfield is mowed using a mower-conditioner. The best time is when the grass is mature, but not old. The mowing needs to happen when there is a window of three to five days AFTER when the hay can dry. Wet hay is a mold party waiting to happen.


  • When the hay is cut, the mower conditioner cuts the grass, which then goes through the conditioner to crimp the hay. This makes the drying process a little faster. Most mower conditioners will crimp the hay every 4 inches, but some super mower conditioners crimp the hay at smaller increments to speed up drying.

Windrows of drying hay.


The mower-conditioner machine also creates those rows of cut grass in the fields.


  • These are called windrows, and the mower conditioner determines how wide the windrows are.


  • If you need to, you can then come over the windrows with a tedder. This handy machine spreads out the windrows. To speed up the grass drying process. Must outrun the rain!


  • A few more steps – if the windrows have been spread out by the tedder, then the rake can come along and put them back into windrows. Alternatively, the rake can turn over the windrows if they were not spread out by the tedder.

Now it’s finally time to bale the hay.


  • The baler sucks up the windrows, and creates bales or round bales.


  • Different balers create different sizes of bales. It may be a two-string, a three-string, or a baby-sized round bale, or a monster round bale.

There’s quite a lot of land, equipment, and dodging weather for this to happen. And, it can just as easily be ruined with the wrong timing or busted equipment.
