From Silage Packer
Driving will compress the air out and pack down the crop. It is an incessant process of direct point pressure which causes a highly dense and level result. The Spanjer Impact Silage Packer, packs down firmly, with variable weight according to your tractor and type of crop. The raking action of the rims does a complete job on the suface, resulting in less air under the tarp and a more stable driving surface. When there is 500 to 1000 hp in the field, The Spajer Impact Silage Packer is the decisive tool on the pile. Just move over 4 to 6 inches each run and repeat until you like the compaction.
