Power Gravity Box Unloads Anything
"It'll unload most anything, including high moisture corn or other grains ¨ even sticky silage or ground feed," says Drew Pattee, president of Derco Mfg., Waupun, Wis., manufacturer of a gravity box equipped with a pto-powered cross conveyor.
"Some of my customers use the box to haul high moisture ear or shelled corn from the field for direct unloading into a grinder or drier. I haven't had any complaints whatsoever about corn bridging in the wagon¨regardless of moisture content. Some farmers use the wagon to feed silage, unloading directly into the feed bunk. I've even heard of some farmers using the wagon for hauling wood shavings," notes Pattee.
The 225 bu. capacity box can be fitted with 18 in. side extensions, increasing its capacity to 300 bu.
The bottom cross conveyor is 19 1/2 in. wide and has slanted paddles to prevent cracking or breaking of corn kernels. The standard model is powered by the tractop's 540 rpm pto (an electric motor drive is optional). Conveyor speed is controlled by a hand operated, variable speed slip clutch. The control lever for the clutch extends out to the side of the unloading gate and, when released, automatically shuts the apron off.
Pattee says the apron will run as fast as you want, or at just a crawl.
Made of 12 ga. steel, the wagon has 37? sloped sides and is braced with 3 in. channel iron. Weighs 1,536 lbs. and is 7 ft. wide by 10 ft. long.
A wagon box (not including the running gear) with the pto-powered apron sells for $1,488, with the option of having the hand operated clutch on either the left or right side of the door. Wagons that empty on the left side are also available.
