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.

Types of Chippers

Whole Tree Chippers

A whole tree chipper feeds entire trees — trunk, limbs, and crown — into a chipping mechanism without pre-processing. These machines handle logs 20" to 40"+ in diameter and produce chips at rates of 50 to 200+ tons per hour. They are used in logging operations, biomass fuel production, and land clearing where entire trees need to be reduced to chips on site.

Whole tree chippers come in two main designs:

Drum chippers — a large rotating drum with knives mounted on its surface. The drum spins at high speed and the knives slice material as it passes. Drum chippers handle irregular material well and produce a consistent chip size.
Disc chippers — a large rotating disc with knives mounted on its face. Material feeds into the disc face and the knives shear it into chips. Disc chippers produce a more uniform chip but require straighter feed material.

Common Applications

Biomass fuel production — chip whole trees and logging residuals into fuel chips for power plants
Pulp and paper — produce chips to specification for pulp mills
Land clearing — reduce standing timber and brush to chips on site instead of hauling whole trees
Logging operations — process non-merchantable timber and tops into saleable chips at the landing

What to Check Before You Buy

Inspect the knives for remaining thickness and even wear. Check the drum or disc for cracking and balance. Inspect the feed system — feed wheels, hydraulic rams, and anvil — for wear and proper operation. Review engine hours and check for structural cracking around the bearing housings and infeed area. Verify the chipper produces chips to your specification (length, thickness, and fines content).
