A grapple assembly configured to be combined with a prime mover vehicle. The grapple assembly has a first tine configured to rotate relative to a second tine. The first tine is held in a first position by a force limiting device during normal operation. This force limiting device is movable between an operational position and a tripped position, and is biased in the operational position. The force limiting device has a pressure relief valve which opens to allow fluid to flow in a first direction when fluid pressure on the relief valve reaches a predetermined amount. The force limiting device is combined with the first tine so movement of the force limiting device from the operational position to the tripped position causes the first tine to rotate relative from the second tine thereby relieving forces generated by the prime mover's hydraulic system.

A coupler assembly having a hydraulic system configured to move locking pins between an extended position where the locking pins are received by lugs in an implement to secure the coupler assembly to the implement, and a retracted position wherein the locking pins are retracted from the lugs to allow the implement to be removed from the coupler assembly. The coupler assembly includes a proximity sensor configured to determine whether the implement is seated properly with the coupler assembly. The proximity sensor is in communication with the coupler's hydraulic system and only allows the flow of hydraulic fluid through the system toward the locking pins when the implement is determined to be properly seated with the coupler. The coupler assembly further includes an indicator in communication with the coupler's hydraulic system and configured to visually indicate whether the implement meets certain conditions to indicate a proper attachment.

In addition, each cutting-edge section is linearly movable between an extended position and a retracted position wherein the cutting-edge section floats linearly (generally upward) to contour to the ground. The linkage assembly is operatively combined with a biasing member. The biasing member urges the surface engaging assembly toward the operational position and the cutting-edge section toward the extended position.

A mechanical grapple attachment configured to be combined with a prime mover vehicle. The mechanical grapple attachment comprises a grapple assembly having a first tine pivotally combined with a second tine. As the prime mover's arms are tilted forward, the first tine moves toward the second tine. The second tine pivots in the same direction until it contacts the arm of the prime mover vehicle and is prevented from pivoting further. The first tine continues to pivot toward the second tine causing the grapple assembly to compressively grasp a load between the tines. The second tine includes a roller configured to contact the arm of the prime mover vehicle as the first tine is tilted toward the second tine. The roller helps ensure a smooth engagement between the lower tine and the arm with limited friction as the roller contacts and travels along a portion of the arm.
A brush cutter device having a latch assembly for securing a movable cutter guard in a closed position when the brush cutter is tilted beyond a predetermined angle. The guard is combined with a side of the housing and movable between a closed position and an open position. A latch is combined with a portion of the housing and is capable of moving between a retracted position wherein the guard is able to move freely between its open position and its closed position and an engaged position wherein the latch prevents the guard from moving to its open position. Upon tilting the brush cutter beyond a certain angle, gravity acts on the latch causing it to move from its retracted position to its engaged position. The guard would move from its closed position to its open position upon tilting the brush cutter beyond a certain angle, however, the latch is moved beyond its pivot point before the guard moves beyond its pivot point to lock the guard in its closed position.
