The 5 tines design mechanical grapple is the ideal excavator attachment for handling materials very well, such as land clearance, material sorting, general forestry work, demolition, etc. Switching the support pin position to the 3 holes on the weld on mount could help you adjust the 3 tines parts angle to meet your drive habit. If you need to put the mechanical grapple on a quick coupler, please do show us more details of your machine and you quick coupler, since the different quick coupler design, there might be risk of the supporting rod and the quick coupler interfere with each other. If the risk come out, we have to modify the design to make the mechanical grapple match your machine and quick coupler.
