What GPM does a skid steer screening bucket need?

Most skid steer screening buckets require 15 to 30 GPM of auxiliary hydraulic flow. Standard-flow skid steers typically produce 15 to 22 GPM, which is adequate for many screening buckets. High-flow buckets that require 25+ GPM need a high-flow skid steer or a hydraulic upgrade. Always check the bucket manufacturer's specifications against your machine's auxiliary flow rating before purchasing.

Can I use a screening bucket on a Bobcat?

Yes. Most screening buckets use a universal skid steer quick-attach plate that fits Bobcat and other major skid steer brands. The key factor is not the brand of skid steer but the machine's auxiliary hydraulic flow and lift capacity. Check your specific Bobcat model's specs to make sure the screening bucket you are considering is compatible.

How many yards per hour can a skid steer screening bucket process?

Typical throughput ranges from 10 to 25 cubic yards per hour, depending on material type, moisture content, screen opening size, and operator technique. Dry, free-flowing topsoil screens at the higher end of that range. Wet or clay-heavy material drops production significantly.

Is a screening bucket worth it for a small landscaping business?

For many small landscaping operations, a skid steer screening bucket is one of the best equipment investments available. If you already own a skid steer, you add screening capability for $6,000 to $20,000 instead of $50,000+ for a standalone screener. The screened product sells for $15 to $25 more per cubic yard than raw material, so the bucket can pay for itself within a few months of regular use.

What is the difference between a vibrating screening bucket and a rotary screening bucket?

A vibrating screening bucket uses a hydraulic motor to shake a flat mesh screen. Material falls through the mesh openings as it vibrates. This design is simpler, less expensive, and works well with dry, free-flowing material. A rotary screening bucket uses rotating drums, blades, or star discs to tumble and separate material. Rotary designs handle wet, sticky, and clay-heavy material much better because the rotation is self-cleaning. Rotary buckets cost more but offer greater versatility.

When should I upgrade from a screening bucket to a standalone screener?

When your screening volume consistently exceeds 20 to 25 cubic yards per hour, or when you find yourself screening for more than half of your working day, a standalone screener will improve your productivity and product quality. Screening buckets top out at roughly 150 to 200 cubic yards per full working day. A small shaker screen or trommel can double or triple that output with one operator.

Ready Mix Concrete vs On-Site Batch Plant: Which Saves More Money?

Name: Grinder Crusher Screen
Telephone: 770-433-2670

Ready mix concrete costs $125–$195 per cubic yard delivered. Producing your own on-site runs $40–$80 per cubic yard in materials. The math looks obvious.

But the full picture includes equipment cost, permitting, staffing, aggregate sourcing, and minimum viable production volume. There is a clear break-even point. Below it, buying ready mix makes more sense. Above it, owning a plant wins decisively.

This guide walks through the calculation so you can make the right call for your operation.

What Does Ready Mix Concrete Actually Cost?

Current market rates in 2026 vary significantly by location. Standard mixes in rural areas run $130–$165 per cubic yard. Urban markets push that to $165–$195. Specialty mixes or small loads can hit $180–$250.

Those headline numbers hide several costs that add up fast.

Minimum load fees. Most ready mix companies charge a short-load fee of $40–$80 per cubic yard, or a flat surcharge of $50–$150 per delivery, for orders below their minimum load threshold (typically 7–8 yards). If you are ordering small batches frequently, your effective cost per yard climbs well above the stated rate.

Detention time. Most contracts include a set amount of free on-site time before detention charges start. After that, most suppliers charge by the minute. Read your contract before the truck arrives — a slow pour or an access problem can add $100–$300 or more in waiting fees per truck.

Supplier scheduling. You work around their delivery window, not yours. On time-sensitive pours, that constraint creates real operational problems.

Mix design limitations. You get their standard mixes. If your project calls for something specific, you either pay a premium for a custom batch or you make do with what they offer.

What Does It Cost to Produce Concrete On-Site?

The material cost per cubic yard for a standard 4,000 psi mix breaks down like this:

Cement: 6 bags (564 lbs) at approximately $0.07–$0.09/lb (bulk delivered) = $39–$51/yd³. Bulk cement delivered to a batch plant runs $130–$180 per short ton — this is the biggest variable in your cost and the biggest savings driver versus buying ready mix.
Fine aggregate (sand): $8–$15/yd³ of concrete
Coarse aggregate (stone): $10–$18/yd³ of concrete
Water: negligible
Admixtures (air entrainment, water reducer): $2–$8/yd³ typical
Total material cost: $59–$92/yd³ for a standard 4,000 psi mix

That is the raw material number only. It does not include plant ownership cost, power, operator wages, or maintenance.

The gross material savings over buying ready mix runs $35–$115 per cubic yard, depending on your market and cement prices. The wide range reflects real variability: a contractor in a rural area with high delivered concrete prices sees dramatically better economics than one in a competitive urban market.

The Real Break-Even Calculation

Numbers on paper only mean something when you run them against a real scenario.

Scenario 1: Contractor Doing $2 Million Per Year in Concrete Work

Annual ready mix spend: 3,000 yd³ at $175/yd³ = $525,000/year
On-site production cost: materials $75/yd³ + allocated plant cost (operator, power, maintenance) $15/yd³ + aggregate handling $8/yd³ = $98/yd³
Savings per yard: $175 − $98 = $77/yd³
Annual savings at 3,000 yd³: $231,000/year
Used batch plant cost to buy and set up: $150,000
Payback period: $150,000 ÷ $231,000 = approximately 8 months

At 3,000 yards per year, plant ownership pays back in under a year and generates strong annual savings from that point forward.

Scenario 2: Higher Volume Operation at 10,000 yd³/Year

At scale, your aggregate and cement purchasing power improves. Material cost per yard can drop further as you negotiate better bulk pricing and improve plant efficiency.

Annual savings at 10,000 yd³ and $77/yd³ savings: $770,000/year
Plant cost to buy and set up: $200,000
Payback: approximately 3 months
After year 1: $770,000/year in margin from the spread

That is the math that makes plant ownership compelling. Volume changes everything. The plant cost is fixed. The savings per yard compound with every yard you produce.

Beyond Cost: The Non-Financial Case for Owning a Plant

Some of the best arguments for owning a plant do not show up in a cost spreadsheet.

Schedule control. You batch when you want to, not when the ready mix supplier can deliver. On large pours with tight placement windows, this is not a convenience — it is a production requirement.

Mix design control. You specify exactly what goes in every batch. No arguing with a dispatcher about water additions or slump adjustments at the truck. If your QC program calls for a specific water-cement ratio, you control it.

Remote locations. In rural or remote areas, ready mix delivery may not be available at all. When it is, the distance premium can run $50–$100 per cubic yard. Owning a plant eliminates that problem entirely.

Quality certification. Some precast and DOT contracts require the producer to own their batch plant and run a formal QC program. Buying ready mix from a third party does not satisfy that requirement.

Competitive advantage. A contractor who can self-supply concrete can bid work that concrete buyers cannot. When ready mix supply tightens or prices spike, you are insulated.

When Buying Ready Mix Makes More Sense

Plant ownership is the wrong call in several real situations.

Annual volume below 2,000 yd³. At this level, the economics are marginal in most markets. The plant sits idle too much of the year — you are paying carrying costs on equipment that generates savings only part of the time.

Highly variable demand. A plant you cannot keep running becomes a maintenance liability. If your concrete volume swings 50% year to year, the equipment sits idle during down cycles and still needs to be maintained.

No reliable aggregate supply. If you cannot source sand and stone consistently at reasonable prices, the material savings in the model above disappear. Proximity to quality aggregate is a prerequisite, not an afterthought.

No qualified operator. A batch plant needs someone who knows what they are doing. Concrete quality depends on accurate batching, moisture corrections, and mix adjustments. If you cannot staff that role, you cannot run a plant safely or effectively.

Projects that move constantly. If you are never in one place long enough to set up and operate a plant, the logistics of moving equipment constantly eat into any cost advantage. The economics work best when you have a fixed or semi-fixed production site.

The Remote Location Premium

Remote work is where plant ownership economics get genuinely compelling.

Rural ready mix companies often charge $20–$60 per cubic yard more than urban pricing just to cover distance and delivery time. In extremely remote locations — mining sites, mountain projects, island work, or international jobs — ready mix may not be available at any price.

Run the math on a remote project:

Ready mix cost delivered to site: $220/yd³
On-site production cost: $100/yd³ (includes plant cost allocation)
Savings: $120/yd³
At 1,000 yd³: $120,000 saved
Small portable plant cost: $80,000
Payback: under one year, on a single project

This is why remote contractors and mining operations were among the earliest adopters of on-site batching. The numbers make the decision easy.

Ready Mix Producer vs Contractor: Different Calculations

A contractor who owns a plant for self-supply is in a fundamentally different position than a ready mix producer selling concrete to third parties.

For the contractor, the calculation is straightforward: cost per yard to self-produce versus cost per yard to buy. The savings go straight to project margin.

For a ready mix producer, the plant is the core business model. Profitability depends on volume, sales price, market competition, and delivery costs to customers. The question is not whether to own a plant — it is what capacity to build and which market to serve.

For a new ready mix startup entering a market, the volume needed to reach profitability typically runs 15,000–30,000 yd³ per year minimum for a small operation. Below that, fixed costs eat the margin. The business model requires enough volume to spread plant cost, labor, and overhead across a large enough denominator.

Frequently Asked Questions

At what volume does owning a batch plant beat buying ready mix?

At realistic bulk cement prices and typical material costs, plant ownership pays back quickly at even modest volumes. A contractor doing 2,000–3,000 yd³ per year in a standard market typically recoups the plant investment in under 12 months. Below 1,000–1,500 yd³ per year, the math becomes marginal because the plant sits idle too much of the year. The exact break-even depends on your local ready mix prices, aggregate sourcing costs, and what you pay for a plant.

What is the cost to produce one cubic yard of concrete at an on-site plant?

Material cost for a standard 4,000 psi mix runs approximately $59–$92 per cubic yard when buying cement in bulk at current delivered prices ($130–$180/ton). Add $20–$25 per cubic yard for allocated plant ownership cost, operator wages, and power. Total production cost lands at approximately $80–$117 per cubic yard, versus $125–$195 or more for purchased ready mix.

Can a small contractor afford a concrete batch plant?

Used portable plants start around $50,000–$100,000. Add $15,000–$25,000 for setup. A contractor doing 2,000–3,000 yd³ per year can typically justify this cost in most markets. At $75–$80 per yard savings and 2,500 yd³ per year, payback runs under 12 months. Financing is available that keeps monthly cost well below most contractors' monthly concrete spend.

What happens to my plant between projects?

A portable plant is an asset you can sell, store, or keep for the next job. Used plants from known brands hold 50–75% of their value when well-maintained. If you buy a $100,000 plant and can sell it for $65,000 after three years of use, your net equipment cost is $35,000, not $100,000. Treating the plant as a depreciating asset rather than a sunk cost changes the math considerably.
