Harvest Tec’s Preservative

Maximize the number of acres baled per day with a chemically buffered form of propionic acid formulated to prevent spoilage of valuable hay crops. John Deere Green-Gard Hay Preservative is gentle on your baler with a pH of 6.0 that is as neutral as rainwater, yet it is just as effective as straight propionic acid. It works on all types of hay, including alfalfa, grass and other crops susceptible to spoilage at higher moistures.

Benefits of using Harvest Tec’s Preservative:

  • No more waiting on the weather, bale when you’re ready at moistures up to 30%
  • Start working earlier in the day and later in the evening
  • Bale at higher moistures without worry of heating or mold damage
  • Hay treated with Baler’s Choice is greener and higher in feed value
  • When compared to dry preservatives and inoculants, Baler’s Choice is easier to apply, gives more consistent coverage, and won’t clog application equipment
  • Works well on ALL types of hay
  • Non-corrosive buffered formula won’t harm expensive baling equipment, the user, or livestock
  • Baler’s Choice treated hay can be stored for years and will look and feed as well as when it was first baled
  • Baler’s Choice is ok to store outside as it won’t freeze and won’t lose effectiveness over time
