FEAUTURES & BENEFITS Harrows are used to repair pugged pastures and carry out relatively light maintenance and can be beneficial all year round. The inedible area around manure can represent from 5% to 30% of the pasture therefore as the cattle do not eat around the border of the manure the grass becomes long and rank. The area of unusable pasture can increase by two to three times in a very short time depending on the weather. Therefore the amount of available feed is noticeably reduced. Harrowing encourages pasture growth. Growth increases profits. And now, with the escalation in the costs of artificial fertilizer, more than ever before, the modern farmer cannot afford to be without a low cost maintenance free Hooper Douglas Chain Harrow. By spreading animal manure, it not only puts the natural nutrients back into the soil, but also assists in the eradication of profit eating parasites. The original Hooper Douglas Chain Harrow design has been proven for over eighty years. It gives overall even ground coverage and prepares fine, level seedbeds. The harrow rejuvenates tired pastures and encourages and stimulates all grass growth. The Hooper Douglas Chain Harrow allows complete coverage of all ground contours by means of round welded rings joined with spiked links- the popular ten foot set has 320 ground contact points, a feature which also minimizes wear as the rings rotate when the harrow is in operation. For general harrowing over cultivated ground, or hitched up behind your disc harrows, the Hooper Douglas Chain Harrow leaves an even, level finish. If extra smoothing is required, the harrow can be turned upside down and used as a levelling matt.
