Tire Cultipacker
Minnesota farmer Harry Zimmer, of Raymond, and his son, Randy, used old truck tires to build themselves a 46-ft. wide cultipacker for pulling behind their field cultivator.
"We like to use the packer on our peat ground to pack the soil for a uniform seedbed, and to help conserve moisture," points out Randy.
The rig features a 23-ft. wide main section with two 11 1/2 ft. wings that fold directly behind the main section for transport, using two, 2 by 24-in. hydraulic cylinders.
To make the cultipacker, the Zimmer's used 5610-by-20 truck tires - 14 on each wing and 28 in the center section. They simply slid the tires onto a round, water-tight axle - they aren't fastened to the axle or to each other. Randy says the tires aren't filled with concrete or pressurized. If extra weight is needed, the axle is filled with water.
