Three material handling options in one package. The base can be used as a log grapple, or used with the tines accessory sporting 6 tines each side, or the clamshell bucket. The base is a GRA-R 21 log grapple. It can open up to 50 inches and closed down to 4 inches. It can handle logs with precision. The heavy duty tines are well suited for handing unusual load materials such as brush or firewood cuts. The clamshell can then be used as a material handling bucket. It can shovel up shavings or moving mulch and dirt. Changing between the two accessories is easy with the built in catches for the base arms and cotter pins at the end of the stays. Overall this is a very versatile system.
