Abstract: A resource tagging service allows resource tags to be created and associated with computing resources in a service provider network. The resource tags can be utilized to search, collect, filter, organize and otherwise manage computing resources in the service provider network having matching tags, and/or to perform other types of functionality. A resource groups service allows customers and/or other users of the service provider network to view and access collections of computing resources that share common resource tags and/or other attributes. Resource groups can also be evaluated in order to identify computing resources in a service provider network for which certain types of actions or other functionality is to be performed. Membership of resource groups can also be evaluated over time and inferences can be drawn from the membership and from operational information associated with the member computing resources.

Abstract: A vine crop harvester having improved harvesting features for reducing damage to the vine crop and increasing the efficiency of the harvester is provided, wherein a harvesting apparatus attached to a tractor has a digger chain employed to carry the vine crop upwardly from the ground to a pinch roller subassembly, the digger chain forming a shallow angle with the ground surface to reduce slippage on the belt to reduce abrasion and other damage to the crop being harvested. A digger blade is disposed adjacent the lower end of the digger chain, the blade having a base plate, a stainless steel cutting blade at an upper front surface thereof, and a PTFE layer fastened at an upper rear surface thereof, the spacing between the digger blade and the digger chain being adjustable and the angle of the digger blade being adjustable as well.
