DRILLING FLUID SYSTEM
The Ditch Witch FM 13 Drilling Fluid System is the largest of three stand-alone, modular fluid systems for mixing drilling fluid additives with water and delivering the slurry to directional drilling units for drilling, backreaming and product pullback. Powered by a 13-hp gasoline engine, the constant-grease seal pump moves 42-viscosity slurry at a rate of 200 gpm. Maximum flow rate is 300 gpm of 26-viscosity fluid. The system is available with either a 500- or 1,000-gallon tank. It is equipped with two hoppers: one for dry fluid additives and the other for liquid mixtures and enhancers. Ditch Witch

Stens' new line of mulching blades, called Raptor blades, have an aerodynamic design enabling them to move more air with less horsepower. Raptor blades feature reverse-lift mulching and a longer cutting edge to aid in the re-cutting of clippings for quicker decomposing. The blades hold a cutting edge that is longer than standard blades. They fit a variety of applications, including John Deere, Bobcat and Snapper. Ariens Company

The 7×7-inch book with spiral binding includes 17 field guidelines, two methods for evaluating stem decay, listings of common defects and a “how-to-prune” diagram. The book also includes 29 color photographs and 38 illustrations. Safetrees.com
