Crop Topper

"Simple Cover to Protect Your Valuable Crop"

A cost effective alternative in plastic covered hoop structures, developed from the Budget Span, this model removes the crop support option to give a clear 23 feet (7 meters) span. The Crop Topper has been engineered so that the strength is in the heavy duty posts, allowing a post height of up to 6 feet 10 inch (2.1 meters) ideal for fitting windbreak or shade cloth to the sides. The centre of the house rises up to an impressive 12 feet 5 inch (3.8 meters) giving plenty of air over your valuable crop.

Harford's patented unique modular system allows the bay to grow lengthways in multiples of 9 feet 10 inch (3 meters) and widthways in 23 feet (7 meters) spans.

Crop Toppers are fabricated from galvanised high tensile steel with the one-piece hoop design offering superior strength. Harford's only use premier covering materials 200 micron thick, wide one-piece rolls and AVA polymers to ensure long life and the best growing conditions.
