Tooth Holders: Weight Range 2.5-8.5 kg

Component Specifications

Definition

Tooth holders are structural components in agricultural scarifiers designed to rigidly hold and align cutting teeth at optimal angles for soil penetration and fragmentation. They provide mechanical interface between the scarifier frame and replaceable teeth, ensuring consistent depth control and operational stability during tillage operations.

Working Principle

Tooth holders function by providing a rigid mounting platform that transfers mechanical forces from the scarifier frame to individual teeth. They maintain precise tooth orientation (typically 15-25 degrees from vertical) to optimize soil cutting action while distributing impact loads across the holder structure to prevent premature failure.

Materials

Medium-carbon steel (AISI 1045/1050, about 0.45-0.50% C) or alloy steel (AISI 4140) with hardness 40-45 HRC; Optional wear-resistant coatings: tungsten carbide overlay or hard chrome plating (0.05-0.10mm thickness).

Frequently Asked Questions

How often should tooth holders be inspected?

Inspect tooth holders every 50 operating hours for cracks, wear, or deformation, and replace if wear exceeds 20% of original dimensions.

Can tooth holders be repaired?

Minor wear can be built up with hardfacing, but cracked or severely deformed holders must be replaced to maintain structural integrity.
