摘要： A sod laying machine having front and rear sections articulated together. A boom on the front section has arms extending forwardly, with gripper arms extending downwardly from the boom to grip a roll of sod. A control roller connected to the boom arms drives the sod roll to control its speed of unwinding. The sod roll has its grass side facing outwardly and its top unwinds rearwardly so an operator in a seat at the front of the machine, between the boom arms, has an unobstructed view of the critical area of sod extending in the air from the roll to the ground, to reduce the likelihood of buckles and tears therein. The machine passes over the sod after it is laid, to roll the sod.

摘要： A sod harvester in which sod is cut, conveyed upwardly, and then travels downwardly over a floppy conveyor and falls into a roll forming enclosure formed by a bottom conveyor and a vertical conveyor. The floppy conveyor swings downwardly at the start of roll forming, to reduce the free fall of the sod, and swings upwardly as the roll grows. When the roll is formed, the bottom conveyor is unlatched and tilts downwardly to discharge the roll, at the same time pulling into cocked position a core tube injector arm. When the roll discharges, the bottom conveyor snaps upwardly, releasing the core tube injector arm which injects a fresh core tube into the roll forming enclosure. The sod is rolled with its grass side outwardly to facilitate laying and to protect the grass roots. A tray on a cart at the end of the harvester receives the discharge roll and can convey it to either side of the cart. When the tray reaches either side of the cart, a cam tilts the tray to discharge the roll onto the ground clear of the next pass of the harvester.

摘要： A sod laying machine having front and rear sections articulated together. A boom on the front section has arms extending forwardly, with gripper arms extending downwardly from the boom to grip a roll of sod. A control roller connected to the boom arms drives the sod roll to control its speed of unwinding. The sod roll has its grass side facing outwardly and its top unwinds rearwardly so an operator in a seat at the front of the machine, between the boom arms, has an unobstructed view of the critical area of sod extending in the air from the roll to the ground, to reduce the likelihood of buckles and tears therein. The machine passes over the sod after it is laid, to roll the sod.

摘要翻译： 一种麦田收割机，其中切割了草皮，向上传送，然后向下运送在软盘输送机上并落入由底部输送机和垂直输送机形成的卷筒形成箱中。 软盘输送机在卷成形开始时向下摆动，以减少草皮的自由下落，并随着卷的增长而向上摆动。 当辊形成时，底部输送机被解锁并向下倾斜以排出辊，同时将其拉入定心位置的芯管注射器臂。 当辊排出时，底部输送器向上卡紧，释放芯管注射器臂，其将新鲜的芯管注射到辊成型外壳中。 草皮侧面向外滚动草皮，以方便铺设和保护草根。 在收割机端部的推车上的托盘接收排出的辊并且可以将其传送到推车的任一侧。 当托盘到达推车的任一侧时，凸轮倾斜托盘将卷筒卸下到地面上，不受收割机的下一次通过。
