Real-World Performance of ASV Track Loaders Across Terrain and Tasks

[MikePhua]

The Rise of ASV and Its Positrack Legacy
ASV (All Season Vehicles), founded in Minnesota in the 1980s, carved its niche by developing rubber-tracked compact loaders with exceptional flotation and traction. Their proprietary Positrack undercarriage system, which uses multiple small wheels and a flexible track design, was engineered to reduce ground pressure and improve ride quality. ASV’s innovations eventually attracted the attention of Caterpillar, leading to a partnership and shared undercarriage designs in models like the CAT 247B2.
The PT series—such as the PT50, PT60, and PT80—represents ASV’s evolution from the earlier RC models. These machines are known for their smooth ride, two-speed travel, and compatibility with turf tracks, making them suitable for landscaping, trail building, and snow removal. ASV’s compact loaders have been widely adopted in North America, especially in regions with soft soils, dense forests, and seasonal snow.
Undercarriage Durability and Terrain Sensitivity
Operators consistently praise ASV’s undercarriage for its comfort and traction, but caution against prolonged exposure to sharp rocky terrain. The rubber rollers and flexible track system are designed for low-impact environments, but aggressive use in gravel or rocky soil can lead to premature wear.
Observed wear patterns include:

• Chipping of outer rollers after 200+ hours in rocky conditions
  
• Grooving in rubber tracks from stump impacts
  
• Track separation in extreme abuse scenarios
  

Recommendations for longevity:

• Rotate inner and outer rollers periodically
  
• Avoid burying the undercarriage in sharp aggregate
  
• Inspect track tension and alignment every 50 hours
  
• Use turf tracks for sensitive surfaces like lawns or golf courses
  

In one case, a forestry operator ran a PT60 over stumps and debris daily. After 2,200 hours, the original track began separating at the Kevlar lining, but the operator considered this acceptable given the abuse.
Cab Comfort and Control Feedback
ASV loaders are often compared to CASE and Bobcat machines in terms of operator comfort. The PT series is described as riding “like a Cadillac,” especially when compared to rigid-framed competitors. However, some users note that the cab could benefit from better sealing and ergonomics.
Cab feedback includes:

• Smooth ride over uneven terrain due to suspended undercarriage
  
• Bucket pins on older models may be undersized (1-inch vs. 1.5-inch)
  
• Newer PT models have upgraded pins and reinforced mounts
  
• Visibility and control layout are generally well-received
  

Operators who grease bucket pins regularly report minimal wear, even on older RC50 units. One user with over 2,000 hours on an RC50 still had original tracks and functional pins, attributing longevity to consistent maintenance.
Speed and Maneuverability in Field Conditions
The two-speed travel feature in PT60 and PT80 models offers impressive mobility. On flat ground, these loaders can reach speeds that rival wheeled machines, making them ideal for snow pushing and trail grading. The SR80, for example, has been used to pile snow the size of vans and climb over them with ease.
Performance highlights:

• Fast travel speed in two-speed mode
  
• Excellent traction in snow and soft ground
  
• Low ground pressure allows operation in wetlands and turf
  
• Turning on pavement causes less wear than expected
  

Contrary to early dealer warnings, ASV tracks wear slowly on pavement when turns are planned and executed smoothly. One operator found that his CAT 247B2 (with ASV-style undercarriage) turned faster and with less friction than his previous Bobcat CTL.
Planetary Gear Maintenance and Repair Considerations
Some older ASV models, such as the Positrack 2810, may develop leaks in the planetary gear housing. While not common, this issue can be addressed with seal kits available from dealers or directly from ASV. DIY repairs are feasible but require attention to torque specs and seal seating.
Repair advice:

• Identify leak source before disassembly
  
• Use OEM seal kits for compatibility
  
• Clean mating surfaces thoroughly
  
• Refill with recommended gear oil and monitor for seepage
  

In one case, a user repaired a planetary leak on a 2810 after 1,200 hours of use. The machine had been used for concrete removal and trail cutting, and the leak was the first major issue encountered.
Conclusion
ASV track loaders, particularly the PT series, offer a compelling mix of ride comfort, terrain adaptability, and speed. Their Positrack undercarriage excels in soft ground and snow, while careful operation can extend component life even in rocky environments. With proper maintenance and terrain awareness, these machines deliver long-term value and versatility. Whether pushing snow, cutting trails, or grading turf, ASV loaders continue to earn respect from operators who demand performance without compromise.
