Gregg Tvetene - Billings MT, 59101
International Classification:
A01B 7900
US Classification:
172 1, 172 19
Abstract:
A method the method of transferring a roll of sod while inhibiting an unwinding of the roll of sod comprising the steps of: (a) rolling a slab of sod into a first sod roll; (b) forcing the first sod roll onto a sod roll handling mechanism containing a second sod roll with the first sod roll forming pressure contact with the second sod roll on the sod roll handling mechanism; and (c) advancing the sod roll handling mechanism with the second sod roll while maintaining the first sod roll and the second sod roll in pressure contact to thereby inhibit the unwinding of the first sod roll as the first sod roll is transferred to the handling mechanism and an sod harvester guidance system for maintaining a full cut.
