“Farmers face a lot of down time waiting for trucks to come back from grain elevators,” said Walker said at his Saf-T-Cart offices.

The Rol-Hopper is grain harvest’s answer to the cotton module that was designed years ago in west Texas to receive cotton after being picked from the fields and then left covered in the fields.

James Walker Sr., who knows the challenges of netting a profit from agriculture, created the Rol-Hopper, a farm implement designed to expedite grain harvest.
“Farmers face a lot of down time waiting for trucks to come back from grain elevators,” said Walker said at his Saf-T-Cart offices.
The Rol-Hopper is grain harvest’s answer to the cotton module that was designed years ago in west Texas to receive cotton after being picked from the fields and then left covered in the fields.
The Rol-Hopper will hold 1,000 bushels of wheat, corn or soybeans after they are combined. The top is protected by material that is rolled from one end to the other. At the rear of the big container is the hopper to release the grain at an elevator.
His invention will reduce the cost of trucks, labor and fuel, Walker said.
“A farmer has his grain tied up in the fields waiting for the trucks,” he said. “There are drivers waiting in line at the elevators and laborers left idle in the fields.”
Billy Strohm, a lifelong Delta farmer and now vice president of sales for Saf-T-Cart, said that Walker and he put a pencil to some of the cost advantages of the Rol-Hopper.
For example, one truck could take the place of six trucks hauling grain with the Rol-Hopper in place.
Less trucks, less drivers, less fuel and better utilization of all the resources will cut costs and give farmers more net income. In addition, there will be less maintenance costs and reliance on outsourcing, Strohm said.
Equally important is the quality of the grain protected in a Rol-Hopper rather than left standing in the field.
“The crop won’t be left to languish in the field,” the narrator of a Saf-T-Cart DVD stated.
Daniel O’Brien, an agricultural economist for the Kansas State Research and Extension Service, compiled a spatial grain market economics reporting pertaining to handling and transportation of grain, O’Brien included data on the labor, fuel and lubrication, tires, repairs, taxes, insurance and licensing, and depreciation and interest.
His study showed the following:
• Purchase price of a semi-truck, $25,000 used.
• Life expectancy of vehicle 10 years.
• Salvage value of $12,500.
• Ten tires at a cost of $400 for 20,000 miles driven. The cost for tires has risen because tires are made from petroleum
• Fuel, $3 a gallon for a truck with a 5,5 miles-per-gallon consumption haulning grain at 45 miles per hour. That data is out of date with diesel
(See Rol-Hopper on Page 2)
costing more than $4 a gallon.
• License, insurance could run $2,850 per truck.
• Labor figured at $10 an hour.
Walker’s vision dates back nearly 30 years when he took his most welding business to a new level with the start of Saf-T-Cart.
The products, which include metal carts for welding gases and equipment, are marketed worldwide.
