Specifications include, but are not limited to: 1. The hose reel system shall be constructed of tubular steel and all moving parts shielded. 2. The unit shall be mounted on three wheels, two wheels on a rear axle and a steerable front wheel. The unit must be towable without requiring the towing vehicle to carry a significant amount of weight when the unit is full of water. It shall be designed so that it can be moved short distances and positioned by hand. 3. The unit shall be equipped with fold-down stabilizer legs designed to penetrate the ground aggressively by weight transfer when the load of retracting the hose is present and to relieve penetration when the hose is fully retracted. The stabilizer legs must not pose a hazard to personnel when handling the equipment. 4. The unit must be equipped with a positive level-winding mechanism to assure proper layering of the irrigation hose.
