How Many Yards Are in an Excavator Bucket?

The capacity of a bucket to complete a task is contingent upon the hourly requirement for production and how dense the materials are; the amount of the bucket will be for a particular kind of material, also known as the “fill factor,” and the time of the cycle. The project manager determines the hourly production requirements. The quantity of product per sq yard is calculated from standard reference tables. The duration of a cycle is the time between when a bucket has been full and is filled up again. So if you’re wondering how many yards are in an excavator bucket, keep reading and we’ll get the answer for you.

What Is The Length Of A 1-Yard Bucket?

Available in 58” (1/2 yard) and 62″ (1 yard) widths. These buckets are designed for landscaping materials that require accurate measurements of the products delivered in a container that permits dumping in the back of pickup trucks, if necessary.

What Is A Bucket Of An Excavator?

Before you can determine how many yards are in an excavator bucket, let’s talk about what an excavator bucket is.

Excavators are attachments for digging that have teeth on the arms of an excavator. The excavator operator operates the buckets through the controls located inside the cabin. Excavator buckets are also utilized to move dirt or load dump trucks to transport them to dump locations.

How Many Yards Can Fit Into The Pickup?

A typical size pickup can contain the equivalent of three cubic yards (a complete load). Two cubic yards is around the body’s level. In the case of soils, sands, or gravel, One cubic yard is the minimum suggested on a pickup truck.

How Do You Calculate Excavator Bucket Capacity

The material used for filling is vital since it affects how much weight is per cubic yard, and the filling factor differs by the manufacturer of the bucket. This is critical for determining how many yards in an excavator bucket.

Step 1

Check the specifications for excavating to identify the nature of the material that will be removed. If the object to be removed is crushed stone, it is recommended to consult the Building Estimator’s Reference Book states that crushed stone weighs 2,500 pounds. (1.25 tons) per cup. Yd. In the case of crushed stone, you can search for “crushed stone” on the Fill Factor Data Sheet that comes in the bucket. Fill factors define in a range the amount to which you can load the bucket with the particular material. If the bucket has to be filled with no more than 85 percent filled with crushed stone, then the Fill Factor is in the bucket.

Step 2

The loading process is timed using an electronic stopwatch. Start counting when the excavator’s bucket starts to “dig into” and stop as the bucket continues to dig. Divide 60 times the cycle time to determine the number of cycles per hour. If the cycle takes .5 minutes, 60/ 0.5 equals 120 cycles per hour.

Step 3

Using a calculator, divide the hourly production requirements by the number of hours per cycle. If the management wants 800 tons of material to be moved in an hour, If the machine and operator run the rate of 120 hours per hour, 800 / 120 equals 6.67 tons moved in a cycle.

Step 4

Divide the payload per cycle (6.67 tonnes) by the density of the material (1.25 tons/cu. yd.) to determine the bucket’s nominal capacity. 6.67 1.25 / 6.67 = 5.28 cu yds. 1.25 = 5.28 cu yds.

Step 5

Divide the capacity of the bucket nominally by the fill percentage to calculate the needed bucket’s capacity. 5.28 • 0.85 is 6.21 cu. Yds.

How to Calculate Backfill

Backfills are used to substitute soil or dirt taken out of the earth. This could include the site of a garden for raised beds or a material to put behind a wall to create a retaining one. Backfill is typically calculated so that the backfill should not contain all large stones or other forms of vegetation.

In addition, backfill should not contain wood debris since the material can decay and create underground gaps. The voids may collapse and cause an opening within the center of the filling. Backfill is usually measured in terms of cubic yards or cubic feet.

Step 1

Calculate the volume of the area that needs to be filled. For example, you can calculate the cubic footage of a backfill space that is eight feet in width, six feet deep, and 50 feet in length.

It is the volume that a rectangular cubed is determined by applying the formula of v = + w + d, in which v is the volume and l represent how long the trench is, w is its width, and d represents the depth. By applying the formula with the numbers (8x 50×6) to find the volume of this particular space is approximately 2400 square feet.

Step 2

Find the cubic yardage for the trench. Backfill is usually sold per yard. Similar to concrete, you must convert it from yards to feet. There are 27 cubic feet within the cubic yard. Consider one as a cube 3 feet wide, three feet long, and the depth is 3 feet. It is dividing 2400 into 27 to produce 88.9 cubic yards.

Step 3

In the next step, you could have to fill in a circular hole 10 feet wide and five feet deep. First, we need to determine the size of the hole in the form of a circle. It is the same as Pi multiplied by the radius square, which is the formula 3.14 x r2. By applying these numbers using the formula 3.14 52 = 3.14 (5^2) or 3.14 25. The surface of the base of the hole will be 78.5 sq. feet. The volume is 78.5 five, which equals 392.5 cubic feet, equivalent to 14.5 yards.

Step 4

Determine the number of truckloads needed to fill the two holes using backfill. Keep in mind, smaller trucks have a 10-yard filling capacity, while larger trucks can range from 15 yards to the 20-yard mark. The capacity of the fill material will determine the quantity of Backfill that can be transported across a street or highway. For the round hole to be filled project described in step 3, one truckload with a capacity of 15 yards should be required.

Step 5

Divide the Backfill in Step 2 to determine the number of truckloads required to fill a 10-yard capacity truck. The result is 8.9 loads, which is the total of nine required loads.


By keeping these measurements in your hands (or noted down in our measurement guide), you should have everything you require to begin your search for a used excavator bucket when you know how many yards can be found in an excavator’s bucket. With that, you’ll be well on your way to finishing up your project.
