Use the Happy Horse Handy Shaker for application of diatomaceous earth, salt, fertilizer, seeds, ice melter and more. The shaker uses a thicker grade of plastic than others on the market for increased durability. The top is adjustable, with a total of 12 holes that can be adjusted in size to ensure that just the right amount of product is being spread. Different units of measurement are included on both sizes (L and KG) so you know exactly how much product is being used. Finally, the included scoop makes filling the bottle very easy and reduces mess.
