Wacker Neuson ST27: A Compact Track Loader with Big Ambitions

[MikePhua]

       

Overview of the ST27 Compact Track Loader
The ST27 represents Wacker Neuson’s entrance into the compact-medium CTL (compact track loader) market. Launched in 2023 and manufactured in the U.S., it challenges larger competitors while remaining easily towable at 7,350 lb operating weight with a rated operating capacity (ROC) of 1,890 lb at 35% tipping load . Powered by a 74-hp Kohler KDI 2504 turbocharged engine, the ST27 achieves an impressive power-to-weight ratio in its class .
Compact Dimensions & Visibility
Boasting just 60 in width and under 80 in in height, the ST27 excels in tight or low-clearance environments . A new unibody design allows the loader arms to hug close to the tracks, improving both side visibility and operator awareness. Rear linkage is aligned with cab rails for unobstructed rearline view .
Lift Geometry & Reach Capabilities
The vertical lift linkage enables:

• 119.9 in hinge pin height
  
• 94.3 in dump height
  
• 36.5 in reach at dump height – facilitating safer, more efficient dumping into trailers or boxes .
  

These specs allow the ST27 to perform like machines that weigh significantly more.
Transmission, Travel Speed & Auto-Shift
Equipped with a standard two-speed drive, the ST27 reaches up to 9.1 mph, with automatic shifting enabled based on joystick input. This auto-shifting feature reduces operator workload and ensures smoother transitions—operators may disable it if desired .
Operator Comfort and Control Options
The cab delivers industry-renowned comfort:

• Spacious layout with wide entry door and grab handles
  
• 5.7‑inch color display with programmable joystick sensitivity and travel response
  
• EH joystick is standard, offering selectable ISO or H‑pattern configuration via in-cab switch
  

Ergonomics include angled footrest, adjustable armrests and seat, plus overhead switch layouts that reduce fatigue on long shifts.
Maintenance Accessibility and Engine Cleanliness
A forward-tilting cab and swing-up cooling package allow easy access to hydraulic and engine components—designed to simplify daily checks and repairs . Air intake is protected by a cyclonic pre‑cleaner that improves filter life. A variable-speed cooling fan aids in cold starts and reduces noise when full fan speed isn't required .
Performance Benefits and Field Feedback
Though peer-reviewed feedback is limited due to its recent release, preliminary observations suggest the ST27 compares favorably to ASV-type units of similar weight. Its low weight makes it viable for smaller trailers and tight transport routes. Users note excellent flotation on soft or wet terrain, thanks to the balanced track-frame design and moderate ground pressure (5.5 psi) .
Chalkboard Comparison: ST27 vs peers
Features listed as bullet points for clarity:

• Operating Weight: 7,350 lb
  
• Rated Operating Capacity: 1,890 lb (35% tip)
  
• Engine: 74 hp Kohler turbo diesel
  
• Travel Speed: 6.4 mph (low), 9.1 mph (high)
  
• Lift Height: 119.9 in hinge pin
  
• Dump Height: 94.3 in
  
• Reach at Dump Height: 36.5 in
  
• Tracks: 12.6 in width
  
• Fuel Capacity: 27.2 gal
  

Real‑World Use & Anecdotes
Contractors report that the ST27 can haul easily behind a 10-k trailer. In one case, a landscape crew deployed the machine for early spring drainage work on soggy turf. It handled mud well with minimal skidding and the auto two-speed drive cut cycle times significantly.
At trade shows, dealers have praised the pivot from legacy skid steer to unibody CTL on the ST27 frame for its modern structural rigidity. Service techs have said the swing-up cooling package is appreciated when troubleshooting engine or hydraulic issues—especially when field conditions make annual maintenance a challenge.
Technical Glossary & Notes

• Rated Operating Capacity (ROC): The safe load at 35% of tipping load.
  
• Hinge Pin Height: Vertical height of loader arm pivot at full lift.
  
• Vertical Lift: A linkage design prioritizing lift height and reach rather than arc motion.
  
• EH Joystick: Electro-hydraulic joystick system allowing electronic control versus mechanical foot-lever systems.
  
• Unibody Frame: Chassis design integrating undercarriage and loader structure for rigidity and visibility.
  

Conclusion: A Solid Choice for Tight Job Sites
The ST27 may be Wacker Neuson’s smallest CTL, but it doesn’t perform small. With a high lift geometry, auto-shifting drivetrain, top-tier operator ergonomics, and exceptional service access, it punches above its weight. For landscapers, site developers, utility contractors—and anyone operating in compact sites—the ST27 offers a compelling modern alternative to heavier machines. And though user reviews remain in early stages, initial feedback underlines a machine that’s durable, productive, and intuitive—worth watching for broader adoption.
