DEF-free compact track loaders help contractors reduce DEF-related downtime, simplify maintenance and keep attachments working. With the new DEVELON DTL26 and DTL30, crews can spend less time managing fluids and more time moving material.
Picture starting your workday without checking DEF levels, topping off secondary tanks or managing extra fluid inventory on-site. You simply start the machine and start moving material.
Maximum jobsite productivity relies on equipment that is ready to perform in any season. Midsize construction equipment without DEF, like the new DEVELON DTL26 and DTL30 compact track loaders, transforms daily operations. By cutting out a fluid that freezes in cold weather and breaks down in hot weather, you can streamline daily maintenance and maximize jobsite uptime.
Why Do Diesel Engines Need DEF?
To meet EPA emission standards, equipment manufacturers traditionally rely on selective catalytic reduction (SCR) systems in engines 75 horsepower and higher.
An SCR system injects DEF, which is a colorless solution of 67.5% deionized water and 32.5% pure urea, into the exhaust stream. This causes a chemical reaction that converts harmful nitrogen oxides into harmless nitrogen gas and water vapor. While effective for reducing emissions, DEF’s high water content makes it vulnerable to challenging jobsite conditions.
Here are a few reasons why:
- Strict temperature limits: DEF freezes at 12°F and degrades when stored consistently above 86°F.
- Storage and sunlight risks: Direct sunlight breaks down the urea, while unsealed containers can allow dirt and dust to contaminate the fluid.
- Specialized handling: Protecting fluid quality requires heated totes, insulated jugs and shaded storage, which can all add extra costs to the jobsite.
Since SCR systems rely on interconnected components, contamination from dust, dirt or degraded fluid can trigger a fault code on the machine. A technician would need to flush the system and clear the codes in order for the machine to get back to work.
How Do DEF-Free Compact Track Loaders Improve Uptime?
DEF-free compact track loaders improve uptime by removing the need to store, inspect, refill or troubleshoot diesel exhaust fluid.
For contractors working in hot, cold, dusty or remote conditions, machines like the DEVELON DTL26 and DTL30 compact track loaders can reduce daily maintenance steps, eliminate DEF-related downtime and lower the risk of fluid-quality or SCR system issues.
Machines built without DEF simplify daily routines and safeguard your bottom line by:
- Streamlining pre-shift checks, such as inspecting grease points, oil levels and air filters.
- Reducing the number of failure points and other issues that lead to forced engine slowdowns.
- Lowering operating costs by eliminating the need for climate-controlled storage, extra filters, diagnostic scans and ongoing fluid purchases.
How Do DEVELON CTLs Deliver Power Without DEF?
The DEVELON DTL26 and DTL30 use an optimized D24 diesel engine. DEVELON designed this engine to deliver heavy-duty power while keeping it under the 74-horsepower limit, so these machines do not need an SCR system.
However, staying under 74 horsepower doesn't mean sacrificing productivity. The DTL26 delivers a rated operating capacity (ROC) of 2,600 pounds, while the DTL30 boasts a heavy-duty ROC of 3,000 pounds (at 35% tipping load).
How Does Operator Comfort Drive Productivity in DEF-Free Loaders?
Eliminating DEF removes daily fluid chores and fault code distractions from the operator's workday. The newest DEVELON CTLs pair that engine reliability with an ergonomic cab layout designed to handle long, demanding shifts. These machines have:
- A wider cab interior, slim corner pillars and a standard rearview camera to make it easier to see around the machine and reduce physical strain.
- High-performing heating and air conditioning to keep the cab comfortable during sub-zero winter days or 100-degree heat.
- Smart controls: An 8-inch touchscreen puts critical machine info at your fingertips, while Smart Assist features like auto self-leveling, return to dig, and bucket shake help newer operators work with speed and accuracy.
Anthony Amato of Amato Excavation had the opportunity to operate the DTL26 compact track loader at a jobsite near Boston.
“The new DTL26 delivers an incredibly smooth and comfortable ride,” he says. “The cab is spacious, the air conditioning keeps up well, and the visibility to the front and sides is exceptional. It provides a premium environment for the operator.”
Can You Maximize Attachment ROI Without DEF?
DEVELON built the DTL26 and DTL30 to power high-demand attachments with full hydraulic force, giving you maximum versatility without DEF-related downtime. That means staying under the 74-horsepower mark without giving up hydraulic muscle.
With the available hydraulic quick coupler, operators can swap between buckets, forks and powered tools in seconds without stepping outside the cab. When jobs call for extra flow, an optional 27 gpm high-flow auxiliary system delivers the power needed to run demanding tools like cold planers, brush cutters and snowblowers.
For tasks like trenching or milling, creep speed control lets operators set a slow, precise travel speed while maintaining full hydraulic power to the attachment.
DEVELON also pairs performance with enhanced site safety, offering an optional 270-degree around view monitor (AVM) camera system and proximity sensors to protect those working in tight spaces.
“The AVM system is a nice feature to be able to see around you and your blind spots,” says Dalton Rasch of Rasch Construction, who operated the DTL30 at a DEVELON training and testing facility.
DEF-free compact track loaders give contractors a practical way to reduce fluid-related downtime, simplify maintenance and keep attachments working across demanding jobsites. By pairing a DEF-free engine design with strong hydraulic performance, operator-focused cab features and jobsite visibility options, the DEVELON DTL26 and DTL30 help crews stay productive in changing weather and tough working conditions.
