摘要： A self propelled forklift vehicle having a frame formed by two spaced parallel longitudinal frame members and a rear transverse frame member. The fork carriage is movable forwardly and rearwardly on the longitudinal frame members, along the path of the machine, and carries a fork tower and forks. The forks can be forced below the vehicle to raise the vehicle up beneath the rear of a trailer for transport. The vehicle's rear wheels, which steer and drive the vehicle, are closely spaced and tiltable from side to side to allow for rough terrain, with the operator seat and motor on opposite sides thereof to balance each other. A manually operated split pulley drive allows creeping of the vehicle at a closely controlled low speed. The fork tines include erectable rollers to support part of the vehicle weight when the forks carry a forwardly extended load, to prevent tipping. A front gate causes discharge of the contents of a pallet onto the ground when the fork carriage is retracted. An automatic centering mechanism returns the rear driving wheels to either front driving or rear driving position as selected by the operator.

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 gang mower having a main frame and a number of individual mower units connected to the main frame. Each mower unit has a pulley driven by a drive belt which extends to a pulley on the main frame, to drive the mower unit reel. A telescopic arm is rigidly connected to the mower unit, extends between the flights of the belts, and is pivotally connected to the main frame between the pulleys. A support strut extends from the telescopic arm to the outer end of the mower unit frame to help align the mower unit. A rear support arm extends laterally from the rear of the mower unit to the main frame to guide the rear end of the mower unit while allowing it to rise and fall. A bias spring exerts downward pressure on the rear support arm to counteract the lifting torque of the drive belt, thereby ensuring that the mower unit will cut at the same height at each of its sides.
摘要翻译：具有连接到主框架的主框架和多个单独割草机单元的组合割草机。每个割草机单元具有由驱动带驱动的带轮，该驱动带延伸到主框架上的带轮上，以驱动割草机单元卷轴。伸缩臂刚性地连接到割草机单元，在带的间隙之间延伸，并且在滑轮之间枢转地连接到主框架。支撑支柱从伸缩臂延伸到割草机单元框架的外端，以帮助对准割草机单元。后支撑臂从割草机单元的后部横向延伸到主框架以引导割草机单元的后端，同时允许其上升和下降。偏置弹簧在后支撑臂上施加向下的压力以抵消驱动带的提升扭矩，从而确保割草机单元在其每侧的相同高度处切割。

摘要： An undercutting knife for a sod cutting machine. The knife has an undercutting blade having a front portion and an upwardly bent rear portion. Connected to the rear portion are two support and guide members, one at each edge of the blade. Each support and guide member extends rearwardly from the blade and has a rear portion projecting laterally of the blade. Mounting arms are connected to the laterally extending portions. The mounting arms, which are connected to mechanism for supporting and reciprocating the knife, are clear of the ground and are spaced laterally of cut sod moving over the knife, so as not to tear the edges of the sod. A guide strip extends rearwardly from the blade between the support and guide members. The support and guide members and the guide strip can be three discrete members or a single integral unit.

摘要： A forklift vehicle has hooks mounted on the forks for preventing removal of a loaded pallet from the forks and a gate for ejecting the contents of the pallet as the forks are withdrawn. The hooks are normally biased out of engagement with the pallet but a cam mechanism moves the hooks into pallet engaging position when the forks are moved to a selected unloading height. The gate is mounted on the rear of the forks and is biased there by two pairs of extensible links. During unloading the forks are moved forwardly and downwardly to bring the gate in front of a pair of stops. The forks are then moved rearwardly, withdrawing the pallet while the gate ejects the pallet contents. The forks are then raised above the stops, allowing the biased links to return the gate to its rear position.
摘要翻译：叉车具有安装在叉上的钩子，用于防止从货叉卸载装载的托盘，并且当叉子被取出时，用于弹出托盘的内容物的门。钩通常偏离与托盘的接合，但是当叉移动到选定的卸载高度时，凸轮机构将钩移动到托盘接合位置。门安装在叉子的后部，并被两对可延伸的链接偏置在那里。在卸载期间，叉子向前和向下移动，以使门在一对停靠站前面。然后叉子向后移动，当门打开托盘内容物时，取出托盘。然后将叉子抬起在止动件上方，允许偏置的连接件将门返回到其后部位置。

摘要： A gang mower typically having five or seven gangs which are raised and lowered by a single piston and cylinder. Lifting arms are fixed to an actuating shaft at each side of the machine and the piston and cylinder are connected between opposed lifting arms to rotate them in opposite directions. An equalizer link connected by cranks to the actuating shafts ensures that the shafts always rotate to equal extents in opposite directions. Chains are connected from the lifting arms to the mowers, the chains and lifting arms being dimensioned so that lifting occurs sequentially, with some of the mowers being lifted before others. The sequential lifting spreads the load more evenly throughout the lifting sequence, thereby permitting a single piston and cylinder to lift all of the mowers.

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 mower having a frame consisting of a top plate and downwardly extending side plates. Reel adjustment members are pivotably connected to the side plates and carry the ends of the reel shaft to adjust the reel position. A bed knife behind the reel is carried by two side arms which extend upwardly and forwardly to the front and top of the mower. The side arms are pivoted at their rear to the frame side plates and are joined at their tops by a transverse bar. The transverse bar is adjustably connected to the frame top plate by an adjustment device to adjust the bed knife position. The rear roller is carried by further side arms also pivoted to the frame side plates and connected at their tops by a second transverse bar which is connected by an adjustment device to the frame top plate. The mower is suspended at its center and drive is applied through a shaft extending over the mower generally parallel to the reel axis, to prevent torque changes from varying the height of an end of the mower.

摘要： A sod harvesting machine travels forwardly along a path of travel and has a sod cutting head pivotally connected to a fixed rear frame by a horizontal front pivot shaft having its axis aligned along the path of travel and located close to the ground, and by a pair of rear pivots. The rear pivots are formed by a pair of curved tracks and rollers at the rear of the cutting head, well above the ground, allowing the front of a conveyor to be brought near the ground and close behind the sod cutting knife. The curved tracks have a common center of curvature located on the axis of the front pivot shaft so that they have the same effect as a horizontal rear pivot shaft located close to the ground and aligned with the front pivot shaft.
