Don’t let their size fool you—compact TLBs deliver impressive performance for their class. They excel at tasks like sidewalk installation, residential excavation, and small-scale demolition work. Their reduced weight also minimizes ground disturbance, making them perfect for working on finished surfaces.
Mid-Size TLBs: The Sweet Spot for Most Applications
Mid-size TLBs represent the most popular category, offering an optimal balance of power, versatility, and maneuverability. With engines ranging from 90 to 100 horsepower, these machines handle the majority of construction and landscaping tasks with ease.
These versatile machines excel at commercial construction projects, road maintenance, utility installation, and agricultural applications. Their lifting capacities and digging depths make them suitable for everything from foundation work to large-scale landscaping projects.
Heavy-Duty TLBs: Maximum Power for Demanding Jobs
Heavy-duty TLBs feature the largest engines (100+ horsepower) and highest lifting capacities in the category. These machines are built for demanding applications like large-scale excavation, heavy construction, and industrial projects.
The increased power comes with enhanced hydraulic systems that provide faster cycle times and greater breakout forces. Heavy-duty TLBs also feature reinforced frames and components designed to withstand the rigors of continuous heavy-duty operation.
Maintenance Tips for Longevity
Daily Maintenance Routines That Pay Off
Successful TLB ownership starts with consistent daily maintenance routines. Begin each workday by checking engine oil levels, hydraulic fluid levels, and coolant levels. Inspect all hydraulic lines for signs of wear or leakage, and ensure all grease points are properly lubricated.
Your daily routine should also include checking tire pressure and inspecting bucket cutting edges for wear. These simple steps take just minutes but can prevent costly breakdowns and extend your machine’s operational life significantly.
Weekly Maintenance: Deeper Inspections
Weekly maintenance routines should include more thorough inspections of critical systems. Check air filter condition and replace if necessary, as dirty filters reduce engine performance and increase fuel consumption. Inspect all pins and bushings for excessive wear, paying particular attention to high-wear areas like loader and backhoe pivot points.
Don’t forget to check battery terminals for corrosion and ensure all lights and safety systems are functioning properly. These weekly checks help identify potential issues before they become expensive problems.
Seasonal Maintenance: Preparing for Peak Performance
Seasonal maintenance is crucial for maintaining peak TLB performance throughout the year. Before winter operations, switch to appropriate hydraulic fluid viscosities and check heating systems. Spring preparation should include comprehensive inspections of all systems after winter storage.
Summer maintenance focuses on cooling system performance and air conditioning functionality. Fall preparation involves checking all systems before potential winter storage and addressing any issues discovered during the operating season.
Safety Guidelines for Operating TLBs 
Pre-Operation Safety Checks
Safety must be your top priority when operating any TLB. Before starting operations, conduct a thorough walk-around inspection to identify potential hazards. Check for hydraulic leaks, damaged components, and ensure all safety devices are functioning properly.
Always verify that your work area is clear of underground utilities before beginning excavation work. Contact local utility location services and use appropriate detection equipment to prevent dangerous and costly utility strikes.
Operating Safety Protocols
Proper operator training is essential for safe TLB operation. Ensure all operators understand machine capabilities and limitations, and never exceed rated lifting capacities or operating parameters. Maintain three-point contact when entering or exiting the operator cab, and always use appropriate personal protective equipment.
When operating near traffic or in populated areas, establish proper safety zones and use spotters when visibility is limited. Never allow personnel to work under raised loads, and always lower attachments to ground level when parking or performing maintenance.
