Hydra Box™

Ag Storm now has the ultimate solution for on-board rock handling for your tractor!

Entirely constructed of high-strength steel & fully powered by your tractor’s hydraulic system, our new hydraulic on-board rock grapple system has the ability to lift 4,000lb rocks out of the ground in seconds – all controlled from the comfort of the cab by an easy to use remote control. All Hydrabox assemblies are mounted onto the front of your tractor using one of our custom-made brackets that bolt right onto the frame.

Gone are the days of wasting valuable time coming back out to the field with a skid-steer, back-hoe or tractor & wagon to retrieve a rock manually and risk further damage to one’s body; grab it the instant you see it, move on & dump it without even getting out of your seat!
