[MikePhua]

The ASV RT-120 is a high-horsepower compact track loader designed for demanding forestry, snow removal, dirt moving, and landscaping applications. With a robust Cummins 3.8-liter turbocharged engine delivering 120 horsepower and 488 Nm of torque, the RT-120 offers the power and durability needed to excel in diverse environments.
Key Features and Specifications

• Engine Power: 120 hp (89.5 kW) from a Cummins QSF3.8, a highly reliable and efficient 4-cylinder turbo diesel engine.
  
• Torque: Peak torque rated at 488 Nm, providing excellent pulling power and responsiveness on rough terrain.
  
• Operating Weight: Approximately 5,550 kg (12,225 lbs), ensuring stability while maintaining versatility.
  
• Tipping Load: Around 4,853 kg (10,700 lbs), allowing the machine to handle heavy loads confidently.
  
• Ground Pressure: Low ground pressure of about 4.3 psi, thanks to ASV’s patented Posi-Track® rubber track system, which features suspended wheels and axles for a smooth ride and optimum traction.
  
• Track Dimensions: 20-inch wide rubber tracks with design features that ensure durability and effective operation over muddy, icy, or brush-covered ground.
  
• Max Travel Speed: Approximately 16 km/h, enabling efficient movement around sites without sacrificing control.
  

Durability and Design for Forestry
The RT-120 is engineered with metal guarding around vulnerable components such as lights, the AC condenser, and the rear screen, protecting vital systems from brush and debris common in forestry operations. Optional factory-installed full rear brush guards further enhance longevity. Its durable construction and innovative internal-drive sprockets maximize power transfer to the tracks with minimal friction loss, eliminating planetary drives and reducing maintenance needs.
Operator Comfort and Usability

• Intuitive joystick controls enhance operational ease and reduce operator fatigue.
  
• The cab provides a clean, comfortable environment with heat and air conditioning, crucial during long shifts in harsh conditions.
  
• Easy service access through a three-panel hood and tilting cooler simplifies routine maintenance tasks.
  

Market Perception and Reliability
Users considering the ASV 120 in forestry note its high horsepower suits aggressive mulching and material handling workloads. However, feedback from operators is mixed; some report minor troubles or limited enthusiasm, while others appreciate its task versatility compared to similar machines. The RT-120’s flexibility as a multi-purpose loader stands out, balancing power and adaptability where many higher horsepower machines are specialized for a single task.
Comparison to Alternatives
The Takeuchi TL12, featuring about 110 hp, garners slightly more favorable user feedback for reliability and satisfaction, especially in aftermarket support and dealer service. Prospective buyers weigh the ASV’s raw power advantage against these reputational aspects during decision-making.
Technical Terms Explained

• Posi-Track®: A patented track suspension system offering enhanced ride comfort, speed, and traction by combining suspended wheels and flexible tracks.
  
• Tipping Load: The maximum safe load before the machine risks tipping forward.
  
• Torque: A measure of rotational force crucial for pushing, pulling, and digging capabilities.
  
• Turbocharged Diesel Engine: An engine that uses forced air induction to increase power output and efficiency.
  
• Track Ground Pressure: The pressure exerted by the machine on the ground, influencing soil disruption and flotation.
  

Real-World Reflection
An operator investing around $150,000 CAD in the ASV 120 configured with a mulching head emphasizes the importance of matching machine choice to application needs. Despite mixed reviews, the RT-120’s power and suspension system make it a viable contender for diverse jobs including forestry mulching, snow clearing, and landscaping, provided one sets realistic expectations and prepares for routine maintenance based on operational severity.
Summary
The ASV RT-120 forestry compact track loader offers class-leading horsepower, advanced suspension, and rugged features tailored for challenging environments. While some users report reliability concerns and tempered enthusiasm, its versatility and power make it a strong option for forestry professionals seeking a multi-functional machine. Comparing this with competitive models like the Takeuchi TL12 helps potential buyers make informed decisions balancing performance, reliability, and total ownership costs.
