This is the Arena Rascal Pro made by ABI Equine. It's a 6.5' drag. It has the ripping teeth to break up compaction and also the profile blade that provides a smooth base underneath the footing. Easy for anybody to operate. It also allows you to work up close the the arena fence without worrying about clipping a panel. I could tell in my own horses this drag is beneficial for both of us. They pay more attention to cues from your legs and feet when they aren't  worried about tripping over big dirt clods and unevenness throughout the arena. ABI recommends a 600cc ATV or bigger to pull this. I pulled this one with a Polaris 850 Sportsman. In low gear with that four wheeler you can go about 10 mph and you don't even know it's back there. You can work a 140'x240' arena in less than 10 minutes an it does and awesome job. The reason I'm selling this one is because I purchased a bigger one. The drag is also a handy tool for conditioning rock driveways and brings the rocks back to the surface. The Arena Rascal Pro costs $2795 new. All parts are replaceable through ABI. The ripping teeth and profile blade show no wear except for some paint missing and will last for a long time.  To learn more vist abiattachments.com.
