The Feed Assist ball elevating tray for our 10-S Tough Cart is on of the best new products in the last 10 years. 10-S is proud to introduce the Feed Assist for ball carts. Simply attach it to your existing 10-S tough cart and have tennis balls at your finger tips for feeding. No more awkward leaning into your cart to find balls at the bottom of your basket. Have the balls at your finger tips with the Feed Assist. Using engineered elastic long lasting bands the Feed Assist is perfectly weighted to lower and elevate with the weight of tennis balls. It will move up as quickly as you can feed so that balls are never more than 8" deep in the cart. Get ready for fast feed drills, cardio tennis and a back saver with the new Feed Assist.
