How Do I Choose The Right Ground Engaging Tool?

To get the most out of your machine and excavator bucket, it’s important to choose the right digging tool (GET) for the application. Here are 4 key factors in choosing the right bucket teeth.

Manufacturing

  • The construction and material of bucket teeth and adapters is a major criterion, as this will directly determine their wear life and strength, but so is the shape and design.
  • Due to cost and pollution reasons, teeth are now mainly cast in foundries in third world countries. The material used in the casting process and the type of mold used will determine the life, breakage and installation time of the tooth. In addition, the heat treatment process will affect the hardness and thus the wear life.

Wear life

  • The wear life of bucket teeth is affected differently by the material used. Sand is extremely abrasive, and the rocks, dirt and other materials being excavated or loaded will affect their wear life depending on their quartz content. The larger the wear surface, the longer the teeth will last before they are replaced.
  • These bucket teeth are best suited for loading and material handling applications, not for excavation or trenching where high penetration and impact forces are required. Large wear surface areas tend to be less efficient when penetrating hard, compacted ground.
  • Penetration force
  • The size of the surface area in contact with the ground during penetration determines the efficiency of the teeth. If the teeth are wide, blunt or have a “spherical” surface area, the bucket will require additional power to penetrate the material, thus using more fuel and putting more stress on all parts of the machine.
  • The ideal design is one that automatically sharpens the saw teeth, i.e., one that continues to sharpen as it wears.
  • To penetrate dense, rocky or frozen ground, you may need sharp “V” shaped teeth, called “double tigers”. These teeth are great for digging and trenching because they allow the bucket to pass through the material easily, but they have a shorter life due to less material and do not smooth the bottom of the hole or trench.
  • Impact resistance
  • Bucket teeth with high impact resistance can withstand penetrating impacts and high breakage forces. These bucket teeth are best suited for excavation and trenching applications with buckets, backhoes or other machines with high digging forces, especially in rocky environments or quarries.
  • The fit of the teeth to the adapter is very important as an improper fit can cause pressure to return to the pin, which can create weak points or the pin may even fall out under pressure.

Our line of bucket teeth and adapters maximize bucket power, minimize power loss, improve performance, and reduce completion time and fuel consumption. We understand the importance of equipping your bucket with the right Ground Engagement Tool (GET) to get the job done, minimize maintenance costs, extend equipment life, and improve performance.
