If saving time, hay and money are important to you than our hay tarps are the right choice. Winkler Canvas hay tarps are the easiest and most cost effective way to cover your hay. Developed in conjunction with farmers and manufactured in a wide range of sizes to suit all types of bales and haystack configurations, our high quality polyethylene hay covers are an economical and cost effective solution for covering hay. Our hay tarps are used by some of the largest hay and flax straw companies in the world, including Schweitzer Mauduit Canada.

  • According to the USDA and Statistics Canada, hay production in these two countries exceeds 155 million tons per year
  • Less than 5% of the production is covered with Haystack Covers or Bale Covers
  • Less than 5% of the production is stored in conventional barns
  • Hay tarps could average a cost of less than $2.00 a ton and return $20 -$50 per ton in price improvement for the better quality hay
  • Horses will not eat wet hay and other livestock can either get sick or refuse to eat the hay
