WHAT IS THE DIFFERENCE BETWEEN A DIGGING BUCKET AND AGRADING BUCKET?

A digging bucket, also known as a general-purpose bucket, is designed to penetrate and break through soil, clay, gravel and other compact material, making it ideal for general excavation and earthmoving work, as well as digging trenches for utilities, foundations and other similar projects. A grading bucket is typically wider and has a smooth edge, making it ideal for levelling and shaping surfaces, usually after the main digging work has been completed. In simple terms, use a digging or general purpose bucket for excavation, and a grading bucket for finishing and ground levelling.

WILL AN AFTERMARKET BUCKET FIT MY EXCAVATOR?

Yes, an aftermarket excavator bucket can fit your machine, provided the bucket is correctly matched to your excavator’s make, model and pin dimensions. Rhinox excavator buckets are available for a wide range of mini diggers and excavators, but it is important to check your pin diameter, pin centres and dipper gap before ordering to ensure the bucket will fit correctly. If you are unsure which bucket is right for your excavator, check out our machine selection tool or contact us directly for assistance.

WHAT MEASUREMENTS DO I NEED WHEN ORDERING AN EXCAVATOR BUCKET?

When ordering an excavator bucket or attachment, the key measurements you need are the pin diameter, pin centres and dipper gap. Taking accurate measurements before ordering will help you select the correct excavator attachment for your specific make and model. If your excavator has a quick hitch or other coupling system, you will need to know if your quick hitch picks up the pin dimensions of the bucket or attachment you're looking to buy. More information about measuring the pin dimensions of your excavator or quick hitch.

WHEN SHOULD EXCAVATOR BUCKET TEETH BE REPLACED?

Excavator bucket teeth should be replaced when they become worn, rounded or damaged. For standard bolt-on bucket teeth, this means when the serrations have worn away, the tooth has become noticeably rounded, or the tooth has snapped.For CAT-style teeth, replace the tooth when the serrations have worn away, the tooth has become rounded, or a hole becomes visible through the top of the tooth. This is particularly important as it indicates the tooth has worn back far enough to expose the adaptor underneath. If the adaptor begins to wear, it can lead to costly repairs, as it is welded to the bucket and cannot be easily replaced.Worn teeth will reduce digging performance and make it harder for the bucket to penetrate tough ground. Continuing to use excessively worn bucket teeth can also put additional strain on the bucket and excavator. Regularly inspect the teeth during use and replace them when they have lost their original profile or are noticeably affecting digging performance.
