The TTT 1600 Table Top Hand Crank requires no electricity and is perfect for home and off grid trimming. It works like all of Toms Tumblers, with the same rate of trimming at the motorized TTT 1600 Tumbler but allows user control with the hand crank processing. The Hand Crank tumbler includes a clear funnel flow bag, clear removable dust cover so you can watch the trimming process, and one net (1/2 inch mesh for trimming). Optional separating and pollen screens are available to purchase. The TTT 1600 Hand Crank is compact and efficient for trimming volumes of 3/4 -1 pound per 3-5 minute cycle – 6 pounds per hour. The frame is made of durable furniture-grade PVC with food-grade aluminum axle and drums. Includes a heavy-duty motor with speed control, quick release catch bag and dust cover. Mesh nets are machine washable. The only tumbler maintenance is lubrication of the tumbler zippers as needed.
