Skid steer hydraulic breakers come in multiple models, each designed for a specific carrier weight class, hydraulic flow range, and application. Understanding the differences between breaker models helps contractors and equipment buyers select the right breaker for their skid steer, ensuring optimal performance, longevity, and productivity.
What Determines the Correct Breaker Model
Several factors determine the correct breaker model for a given application. First, the skid steer's operating weight and carrier class is the primary determinant, as the breaker must be matched to the machine's size and stability. A breaker that is too large for a small machine can cause instability, excessive wear on the loader arms, and reduced maneuverability. A breaker that is too small for a large machine wastes the machine's capacity and may be inefficient for heavy breaking tasks.
Second, the auxiliary hydraulic flow and pressure must match the breaker's requirements. Each breaker model has a specific flow range (20-100 L/min / 5.3-26.4 gpm) and pressure range (90-160 bar / 1305-2320 psi) that must be compatible with the skid steer's hydraulic system. Third, the typical application and material type determine the required impact energy (150-1000+ J / 111-738+ ft-lb) and tool diameter (40-75 mm / 1.57-2.95 in). Fourth, the operating environment and conditions, including noise restrictions, space constraints, and duty cycle, may influence model selection. Always consult the breaker manufacturer's specifications and the skid steer's operator manual when selecting a breaker model.
Breaker Size Classes and Carrier Matching
TGEC offers five breaker models, each matched to a specific carrier weight class. Understanding these size classes helps buyers quickly narrow down the appropriate model for their machine.

It is built for industrial demolition, quarry work, and heavy reinforced concrete. Suggested machines include the Bobcat S770, Caterpillar 272D3, and Case SV340.
Hydraulic Specifications by Model
Hydraulic flow and pressure are critical specifications that determine breaker performance and compatibility. Each breaker model has specific hydraulic requirements that must match the skid steer's auxiliary hydraulic system.
The SB280 requires 20-30 L/min (5.3-7.9 gpm) flow at 90-110 bar (1305-1595 psi), making it compatible with mini skid steers and compact loaders with low-flow auxiliary hydraulics. The SB380 requires 30-50 L/min (7.9-13.2 gpm) at 100-120 bar (1450-1740 psi), suitable for small skid steers with standard auxiliary hydraulics.
The SB680 requires 45-75 L/min (11.9-19.8 gpm) at 120-140 bar (1740-2030 psi), compatible with most standard-flow medium skid steers. The SB880 requires 60-90 L/min (15.9-23.8 gpm) at 130-150 bar (1885-2175 psi), requiring a medium-large skid steer with adequate hydraulic flow. The SB980 requires 70-100 L/min (18.5-26.4 gpm) at 140-160 bar (2030-2320 psi), typically requiring a high-flow large skid steer for optimal performance.
When comparing breaker models, always verify that your skid steer's auxiliary hydraulic flow and pressure fall within the breaker's specified range. Insufficient flow reduces blow frequency and productivity, while excessive flow can cause overheating and component damage. Insufficient pressure reduces impact energy, while excessive pressure can cause seal failure. If your skid steer's hydraulic specifications fall between two breaker models, choose the model whose range best matches your machine's typical operating flow and pressure.

Impact Energy and Blow Rate Differences
Impact energy and blow rate are key performance differences between breaker models. Impact energy, measured in joules (J) or foot-pounds (ft-lb), is the force delivered per blow and determines the breaker's ability to fracture hard or thick materials. Blow rate, measured in blows per minute (bpm), is the frequency of impacts and determines breaking speed for softer materials.
The SB280 delivers 150 J (111 ft-lb) at 1300-1500 bpm, providing high-frequency, low-force impacts ideal for thin concrete and asphalt. The SB380 delivers 250 J (184 ft-lb) at 1100-1400 bpm, balancing impact energy and blow rate for small to medium concrete work. The SB680 delivers 500 J (369 ft-lb) at 1000-1200 bpm, providing medium-high impact energy for reinforced concrete and medium rock.
The SB880 delivers 750 J (553 ft-lb) at 1000-1100 bpm, providing high impact energy for thick concrete and hard rock. The SB980 delivers 1000+ J (738+ ft-lb) at 900-1000 bpm, delivering maximum impact energy for the heaviest demolition and rock breaking applications.
There is an inverse relationship between impact energy and blow rate across the model range: larger breakers deliver more force per blow but at a lower frequency, while smaller breakers deliver less force but at a higher frequency. For hard, thick materials, higher impact energy is more important than blow rate. For softer, thinner materials, a higher blow rate with lower impact energy provides faster, more efficient breaking. Consider your typical material hardness and thickness when balancing these two performance specifications.
Tool Configuration and Diameter by Model
Each breaker model accepts a specific tool diameter, with different tool types available for various applications. Tool diameter ranges from 40 mm (1.57 in) for the SB280 to 75 mm (2.95 in) for the SB980, with larger diameter tools providing greater durability for heavy breaking but less precision for detailed work.
Common tool types include moil points (conical tips) for general-purpose breaking, chisels or flat tools for concrete cutting and precision demolition, blunt or wedge tools for rock breaking, and pyramidal or cross-cut tools for aggressive hard rock breaking. The SB280 and SB380 typically use 40-45 mm (1.57-1.77 in) tools, suitable for light to medium concrete and asphalt work. The SB680 uses 60 mm (2.36 in) tools, the most versatile size for general demolition and site prep. The SB880 uses 68 mm (2.68 in) tools for heavy demolition and road work. The SB980 uses 75 mm (2.95 in) tools for industrial demolition and quarry applications.
When selecting a tool for your breaker model, consider the primary material and application. For general contractor work, a moil point is the best all-around choice. For concrete demolition specialists, a chisel tool provides cleaner cuts. For rock work, a blunt or wedge tool delivers optimal fracturing performance. Always use tools rated for your breaker model's impact energy, and inspect tools regularly for wear, cracks, or mushrooming. ｒｅｐｌａｃｅ worn tools promptly to maintain performance and prevent damage to the breaker's tool bushing and internal components.
Mini Skid Steer Breaker Compatibility
Mini skid steers and compact loaders can use hydraulic breakers, but they are limited to lighter models due to their smaller size, lower hydraulic capacity, and reduced stability. The SB280 is specifically designed for mini skid steers weighing 0.8-1.5 tons (1760-3300 lb), including the Bobcat S70 and Case SR130. The SB380 may also be compatible with larger mini skid steers weighing 1.5-2.5 tons (3300-5500 lb), including the Bobcat S450 and Case SR160.
Mini skid steer breakers require lower hydraulic flow (20-50 L/min / 5.3-13.2 gpm) and provide lower impact energy (150-250 J / 111-184 ft-lb), making them suitable for indoor demolition, backyard-access jobs, confined-space breaking, light concrete and asphalt work, and small landscaping projects. The lightweight design of these breakers ensures stability on smaller machines and allows operation in areas where full-size skid steers cannot access.
When using a breaker on a mini skid steer, always verify the machine's hydraulic flow and pressure, rated operating capacity, and mounting compatibility. Ensure the operator has clear visibility of the breaker and tool, and follow proper operating techniques including avoiding blank firing, maintaining consistent downward pressure, and limiting continuous operation to prevent overheating. Mini skid steer breakers are not suitable for heavy demolition, thick reinforced concrete, or hard rock breaking, as these applications require larger breakers with higher impact energy and more hydraulic capacity.
