Loader Bucket Teeth Replacement

Bucket teeth take the abuse so the bucket does not have to. Replacing them before they wear down protects the bucket and makes digging easier.

Key points

Replace teeth when they are rounded, cracked or exposing the adapter.
Bolt-on teeth suit home shops; weld-on adapters call for a skilled welder.
Bring the old tooth to the supplier and buy matching hardware.
Use new bolts, tighten to the maker's spec and recheck after use.
Lower the bucket, shut down and remove the key before working.

When should you replace bucket teeth?

Worn teeth lose their points and become rounded, which makes the bucket push instead of dig. Replace teeth when they are cracked, bent, badly rounded or worn to the point the adapter beneath is showing. Waiting too long damages the adapter or the bucket lip.

Digging in rocky or hard soil wears teeth faster than loading loose gravel or manure. Inspect them after each heavy-use season or whenever the bucket seems to dig poorly.

What types of bucket teeth are there?

Bolt-on teeth attach to the bucket lip with bolts and are easy to swap. Weld-on adapters are welded to the lip, and a pin-on or clip-on tooth slides over the adapter and locks with a retainer. Some buckets have a straight edge with no teeth at all.

The right type depends on your bucket and the work. Check the bucket maker's information and ask your dealer or a bucket supplier which teeth fit your model.

Bolt-on teeth: simplest to change at home
Weld-on adapter with slip-on tooth: stronger, needs welding for the adapter
Pin or clip retained teeth: quick to replace
Straight edge: no teeth, good for scraping

How do you choose replacement teeth?

Match the tooth to the adapter or bolt pattern, the bucket size and the kind of digging you do. Bring the old tooth to the supplier so they can match it. Buy the matching bolts, washers and retainers at the same time.

Use quality parts. A cheap tooth that snaps in rock is a nuisance and can fly into the cab area if it breaks. Ask the supplier what material and hardness the tooth has and follow the maker's guidance on fasteners.

What is the safe way to replace bolt-on teeth?

Park on level ground, lower the bucket flat to the ground, shut down the tractor, set the brake and take out the key. Wear gloves and eye protection. Remove the old bolts, which may be rusted tight, and clean the mounting surface.

Fit the new tooth, install new hardware and tighten to the maker's specification, which is in their instructions. Recheck tightness after the first hours of use because bolts can loosen as parts seat.

Keep a small box with a spare tooth, a set of bolts and washers, gloves, eye protection and penetrating oil. When a tooth breaks mid-job on a rocky pasture, you can replace it in minutes instead of working with a damaged adapter.

Wear gloves and eye protection
Clean the lip and adapter surface
Use new bolts and washers
Retighten after the first hours of work

What about weld-on adapters?

Weld-on adapters need the right welding procedure, material and preheat. A poor weld can fail, and a cracked weld can damage the bucket. If you are not a skilled welder with experience on bucket lips, hire a qualified welder or take the bucket to a shop.

Do not weld on a bucket with fluid-filled parts or attached hoses without the right precautions. Disconnect batteries and grounds as the manual advises before welding on or near a tractor.

How do you make teeth last longer?

Avoid prying with the teeth, using them as a hammer and driving into solid rock. Dig with a smooth, even motion and tilt the bucket so the tooth edges do the cutting. Keep the bucket cleaned off to spot problems early.

Rotate or replace teeth in sets if the maker allows it so wear stays even. Keep a spare tooth and a set of bolts in the shop.

When is it time to replace the whole bucket?

If the lip is cracked, the sidewalls are torn or the adapters are worn into the bucket, repair may cost more than replacement. Ask a dealer or welding shop for an opinion on structural damage.

Your accountant can tell you how repairs and replacements are treated for your operation.

When to get help: Hire a qualified welder for weld-on adapters or lip repairs, and call the dealer service department about bucket structural damage. Your accountant can explain how repairs are handled in your books.
