Auger Tooth 40/50 | Pengo Attachments By Paladin

Overview

These Pengo auger teeth — the Auger Tooth 40/50, part number 134501 — are a bolt-on replacement tooth for Pengo Aggressor augers, weighing 0.5 lb and rated by Pengo for soil conditions 1 – 2 – 3 — dirt, sand and silt. Like every tooth in the 40/50 family it can be fitted at either a 40° or 50° attack angle, so the same tooth is tuned to the ground by how it is mounted rather than by buying a different part.

Key Features of the Pengo Auger Tooth 40/50

• Pengo standard-grade 40/50 tooth, the baseline tooth for the Aggressor auger family.
• Pengo soil rating 1 – 2 – 3 — dirt, sand and silt, so selection is matched to ground rather than guessed.
• Fits at 40° or 50°, giving two attack angles from one part depending on drilling condition.
• 0.5 lb per tooth — a bolt on auger teeth design using standard carriage bolt (1872) and hex nut lock (134527), so no welding is needed.
• Genuine Pengo auger teeth for Aggressor augers, not an aftermarket substitute.
• Suits skid steer auger teeth replacement as well as mini excavator and backhoe auger drives running Pengo Aggressor heads.

Choosing Auger Teeth: Why Grade Must Match Your Ground

• Wrong grade wears out fast. A standard tooth in abrasive ground is consumed quickly; a carbide tooth in soft dirt is money spent on wear resistance you never use.
• Downtime costs more than teeth. Changing teeth mid-job is lost drilling time, so the right grade first time is cheaper than the cheaper tooth.
• Two angles from one part. Because the 40/50 fits at either angle, attack can be adjusted on site without another order.
• Pengo publishes a soil rating. Most tooth suppliers do not — that rating is what makes matching grade to ground a decision rather than a guess.
• Routine auger teeth replacement is a field job. Because these bolt on, a worn set is swapped on site rather than back at the yard.

Which 40/50 Auger Tooth Grade Do You Need?

Pengo builds the 40/50 tooth in three grades, and the difference is the ground each is rated for. All three share the same mounting and the same 40°/50° angle options, so this is purely a wear decision.

Grade Part number Weight Pengo soil rating Best in 40/50 standard 134501 0.5 lb 1 – 2 – 3 Dirt, sand, silt 40/50HFF hardface 134802 0.5 lb 2 – 3 – 4 Sand, silt, clay 40/50C carbide 134519 0.65 lb 4 – 5 Clay, gravel

If your ground is harder than silt, step up a grade: the 40/50HFF hardface tooth covers sand through clay, and the 40/50C carbide tooth handles clay and gravel. All three bolt to the same auger head.

Which Augers Fit the Pengo 40/50 Tooth?

This tooth fits Pengo Aggressor augers, which mount to skid steer loaders, mini excavators and backhoes through a Pengo auger drive. It is a bolt-on replacement using a standard carriage bolt and hex nut lock, so no welding or special tooling is required to fit it. The same part covers post hole auger teeth duty and general drilling — the auger head decides fitment, not the application.
