Made-It-Myself Sorghum Harvester, Mill
If you've ever watched the labor-intensive process of feeding sorghum stalks through a press, you'll admire Irvin Stephens' self-propelled sorghum mill. Not only does it cut the stalks and feed them through a mill, it pumps the sorghum juice into a tank for later delivery to his cooker. Best of all, Stephens estimates ..........

Made-It-Myself Sorghum Harvester Mill COMBINES Miscellaneous If you ve ever watched the labor-intensive process of feeding sorghum stalks through a press you ll admire Irvin Stephens self-propelled sorghum mill Not only does it cut the stalks and feed them through a mill it pumps the sorghum juice into a tank for later delivery to his cooker Best of all Stephens estimates he has no more than $2 500 invested in the entire machine
I first made a pull-type sorghum harvester using a one-row International corn chopper says Stephens I pulled the chopper blade components off and built a sorghum mill with a ground drive to fit in its place
The mill consisted of three rollers with one at the top turning in one direction and two below it turning in the opposite direction Stalks fed through it are crushed and the juice squeezed out Stephens made his rollers from new pipe that had been scrapped out at a local factory One roller is 12 3/4 in in diameter and the other two are 10 3/4 in He centered a shaft in each with a spacer in the middle He took them to a local machine shop to be trued up before mounting them in position behind the chopper head
Since all three are driven off the same ground drive he had to find a way to reverse one of the rollers Stephens mounted a sprocket and cogwheel on a shaft and connected them to the ground drive A roller chain from the sprocket turns the upper roller A second cogwheel turns against the first reversing the drive direction It was connected to the lower and smaller pair of rollers turning them opposite to the first roller
Stephens made a 15-gal stainless steel catch pan with a stainless screen over the top and a drain in the bottom This was mounted below the rollers to catch the juice
The chopper head worked fine but the slowest ground speed on the tractor was too fast for the mill If rollers on a sorghum mill turn faster than 25 to 28 rpm s it slings the juice out says Stephens
He realized he needed separate speed drives for the chopper head and the mill He had previously seen a mill mounted on a combine but wanted something different When he heard he could pick up an old cotton picker for $1 000 he bought it
Once he had it home Stephens his son and grandson stripped it down to the bare essentials They kept the unit s 130-gal water tank but moved it from behind to alongside the cab
We cut the wheels and drive shafts off the single row unit and modified it with 3-pt hitch mounts recalls Stephens We mounted top link arms to the lift arms on the picker and hung a 3-in pipe between the picker s front wheels with a hydraulic cylinder mounted to it By attaching the arm to the back of the sorghum mill I could adjust the chopper head up or down while raising and lowering the entire unit with the lift arms
Stephens also moved the cab back 31 in so he had a better view of the rollers on the sorghum mill The hydrostatic drive gave Stephens better control over ground speed while hydraulic motors gave him equally good and independent control over the rollers and the chopper head gathering chains A pump mounted to the bottom of the catch pan lets him periodically empty it into the former water tank
Between the hydrostatic transmission and all the hydraulic motors added hydraulic pressure was needed The cotton picker already had two hydraulic pumps on it says Stephens We took the large fan used for picking off and mounted a 28-gpm hydraulic pump there and replaced the smaller hydraulic fluid tank with one that holds 25 to 30 gal
The self-propelled unit with its 107hp diesel engine has more than enough power Stephens says it lets him squeeze enough juice in a few hours to keep him busy cooking all the next day
It takes about 8 gal of juice to make a gallon of sorghum and we process about 300 gal of juice a day he says With the self-propelled mill I can harvest about 100 gal of juice an hour
Stephens expects the sorghum harvester to keep going for at least one more generation He notes his college student grandson is already raising his own sorghum
