METHOD AND APPARATUS FOR REAL-TIME ADJUSTMENT OF THE SIZE AND DRAINAGE TILE CAPACITY OF DRAINAGE TILE SPOOLS AND FOR UTILIZING THE SAME

摘要

A drainage tile stringer system which includes a spool which has an automated hat, which translates along the stinger or shaft of the spool so that the vertical size of the spool is adjustable to accommodate differences in coils of drainage tiles. The system is automated so that a single controller can be utilized to perform all of the hydraulic functions required to load a coil onto the drainage tile stringer system and to adjust the vertical spool dimension.
