The Hoof Boss Mobile holster accepts a Dewalt brand 20V rechargeable Lithium-Ion battery or a compatible replacement. The battery is NOT INCLUDED with the trimming set. Mobile Hoof Care Set can be used anywhere, due to the innovative use of a holstered battery connected to the tool with a short unobtrusive cord. The Hoof Boss is designed to meet the needs of most meat and milk goat owners who maintain a small number of animals. The battery powered version of the Hoof Boss has the same power as the Electric Plugin version. The Basic Goat Set contains three discs. The 8 Tooth Cdisc is used to cut excess material from the goats’ hoof while easily allowing you to see and control how much hoof you are removing. It is much harder to quick your goats’ hoof with the Hoof Boss than with traditional hand shears. There are also two abrasive discs. The Blue Medium Grit- Disc is used on goats with small hooves or regularly maintained hooves that do not require a lot of work to bring the hoof back to confirmation. The Blue Medium Grit Disc is a great choice when treating a foundered goat. The Silver Coarse Grit Disc is best suited for medium to large goat breeds like Boer Goats or those bucks that have rock hard hooves. Climate conditions also determine your choice of disc. If you live in a hot dry climate or in a cold winter area, the hooves are generally harder, and you may choose the Silver Coarse Grit Disc, or the 8 Tooth Disc may be your preferred choice. While warm wet areas the hooves tend to be softer. The 8 Tooth might still be your preference due to the abrasive discs could easily get excessive hoof material buildup and need to be cleaned more often. The Hoof Boss Trimmer is ergonomically designed to help ease the wrist and hand pain associated with trimming your goats’ hooves with hand shears, and it is easily operated with one hand leaving the other hand to wrestle that goats’ ever moving leg.
