Wacker Neuson ST37
The Wacker Neuson ST37 is the largest of Wacker Neuson's new uni-body generation of compact track loaders, joining the line in 2024. Built in Menomonee Falls, Wisconsin, it combines a 74 hp no-DPF Kohler diesel, a 3,700 lb rated operating capacity, and just 4.3 psi ground pressure thanks to wide tracks spreading its 9,014 lb operating weight.
Specifications
Features
Pros
- ✓A 3,700 lb rated capacity from a 74 hp machine is excellent work-per-horsepower, and the 7,400 lb tipping load keeps it planted with heavy pallets.
- ✓Ground pressure of 4.3 psi is the best in the ST line, floating over soft turf and mud that ruts standard mid-frames.
- ✓The Kohler KDI's no-DPF, no-DEF Tier 4 solution eliminates regens entirely - a simplicity argument that resonates with high-hour users.
- ✓Kohler's 4-year/4,000-hour engine warranty plus the 2-year/2,000-hour machine warranty leads the class on coverage.
- ✓The uni-body frame and tilt-up cab make daily checks and major service faster than most competitors.
- ✓Standard 23 gpm aux flow is strong for the class, with a 33.1 gpm high-flow option that handles mid-size mulchers.
- ✓Vertical lift and a 128-inch hinge pin height make truck loading a one-motion affair.
- ✓It undercuts comparable Bobcat T76 and Cat 265 configurations on price by a meaningful margin.
Cons
- ✗Dealer coverage is the perennial Wacker Neuson issue - buyers far from a dealer are effectively self-supporting.
- ✗The model launched in 2024, so there's almost no long-term field history at high hours.
- ✗Resale discount versus the majors applies here too, and bigger machines feel it more in dollar terms.
- ✗The same 74 hp engine that feels strong in the ST27 works harder in this 9,000 lb frame, and operators notice on sustained mulching or hills.
- ✗Wide tracks that help flotation make it wider than some site gates allow, and replacement rubber costs more.
- ✗No 100 hp option in the uni-body generation yet, so power-hungry buyers must jump to the older-design ST50.
- ✗Fewer rental units in circulation means limited chances to demo before committing.
- ✗Basic telematics and no factory grade-control integration keep it behind the tech curve for GPS-heavy contractors.
