DemoDays 26 in Rehlko’s Own Words

We attended DemoDays 26 at Rehlko’s headquarters in Reggio Emilia, Italy. It was a convergence of the cradle of propulsion technology, the “mature” markets of installers, and the watchful eye of industry journalists. We reported on it HERE in our first report, later delving deeper into the rationale behind the multi-cylinder diesel engines, specifically the KDS and KDI series. While you wait for our full report in the issue of POWERTRAIN being distributed in November at EIMA international, here are some excerpts from their press release.

A Short Comment from the President

“The best way to understand an engine isn’t to read about it—it’s to experience the machine it powers,” said Eric Fontaine, President of Rehlko Engines. “Demo Days reflects the way we work with our OEM partners every day. We engineer engines as part of a complete machine, helping our customers deliver greater productivity, reliability and value to the people who depend on their equipment.”

In our initial overview, we summarized the machines we tested at the test track. Below you’ll find some additional information, listed strictly in alphabetical order.

Cormidi

The Cormidi CMF1500 is a multifunction machine that combines ergonomic design, power and versatility. This machine, powered by a KSD 1403NA, is a perfect combination of advanced technology and innovation: with a load capacity of 1500 kg, it is designed to operate in a variety of work settings, including construction sites and agricultural applications. The machine is tracked, offering extra stability and traction on difficult terrain. The “Quick Attach” system makes the CMF1500 extremely versatile. In fact, this mechanism allows the machine set-up to be changed in less than five minutes, an operation that can be carried out by one person without the need for special tools. This makes the machine ideal for different applications without interrupting workflows.

MDB

MDB’s Green Climber series, here represented with model LV400X powered by KSD 1403TC, includes radio-controlled tool carriers designed to operate in extreme conditions, such as high altitudes and harsh environments. Alongside the Green Climber range, MDB also produces a series of Special Machines, including tracked forklifts and skid steer loaders with telescopic booms, ideal for applications requiring precision and durability. MDB utilizes Rehlko engines in the Green Climber range and just expanded the use of KSD engines in the Special Machines product line. The engine’s electronic configuration, combined with a turbocharger, ensures optimal performance under all conditions, reducing maintenance needs and long-term operating costs.

Palfinger

The FLM 25 combines outstanding operator comfort with exceptional maneuverability and performance. Powered by the Rehlko KSD 1403NA Stage V diesel engine, with a 2,500 kg lifting capacity and a dead weight of less than 2,000 kg, the FLM 25 delivers an outstanding payload-to-weight ratio, ensuring stability and efficiency on rough terrain, steep slopes and confined job sites. Features such as 180° steering, 4- way steering, telescopic forks and ground control further increase versatility, enabling precise handling even in the most challenging operating conditions.

The BM 214, powered by the Rehlko KSD 1403TC Stage V turbo diesel engine, complements the range with a compact design that combines off-road capability, high maneuverability and operator safety. Equipped with permanent all-wheel drive and full radio remote control, it provides excellent visibility and enables operators to position the machine precisely where materials are needed. The BM series is the only range of truck-mounted forklifts featuring full radio remote control. In addition, its box-mounted design lowers the center of gravity, enhancing stability and safety during both transport and operation.

Vermeer

Vermeer offers a broad landscape and tree care lineup built around compact, service-friendly equipment for the work European crews do every day, from stump removal to tight-access trenching and attachment-driven tasks. Within that portfolio, the Vermeer ML100 mini loader, SC552 stump cutter and RTX250 pedestrian trencher represent the Rehlko-powered portion of the lineup. Together the three units cover loading, stump grinding and pedestrian trenching, with Rehlko diesel power on the ML100 and SC552 and a Rehlko EFI gasoline engine on the RTX250.

The ML100 mini loader, powered by a 24.7 hp KSD 1403TC diesel engine, is designed for rental, landscaping and tree care applications requiring versatility in confined spaces. With a 950 lb (430,9 kg) rated operating capacity, it supports a wide range of attachments while offering intuitive controls, operator comfort and simplified maintenance. The Vermeer SC552 stump cutter, equipped with a 56 hp KDI 1903TCR diesel engine, is built for demanding stump removal applications. The RTX250 pedestrian trencher, powered by a 25 hp Rehlko ECH740 EFI gasoline engine, is designed for utility installation, irrigation and landscaping work in confined residential and commercial sites.

Weidemann

Weidemann showcased at DemoDays 26 the 2090T telescopic wheel loader, one of four models in the company’s new generation of 4- and 5-ton wheel loaders. Developed for demanding applications in agriculture, equine operations, municipalities and industry, the 2090T combines compact dimensions with enhanced productivity, operator comfort and efficiency. A key innovation is Dynamic Loading Assistance (DLA), an intelligent assistance package that automates repetitive loading tasks . Combining functions such as Automatic Bucket Return, Tilt-in-Assist, Vibrating Function, Lift Height Limiter and Tele-Retract (exclusive to the telescopic models), DLA shortens loading cycles, optimizes bucket filling and reduces operator fatigue, while minimizing machine wear and maintenance costs. The 2090T is powered by the 50 kW (68 hp) KDI 1903TCR HP (High Power) Stage V diesel engine, equipped with DOC and DPF. Paired with Weidemann’s electronically controlled ecDrive transmission, the engine delivers high torque, responsive performance and excellent fuel efficiency.

Wacker Neuson

WL750 wheel loader is one of the Wacker Neuson’s latest compact loaders in action. With an operating weight of around four tonnes, the WL750 combines compact dimensions, excellent maneuverability and a highly efficient loading system, making it well suited for construction, landscaping and material handling applications. Powering the machine is the KDI 1903 TCR three-cylinder diesel engine, delivering 42 kW (57 hp) and 225 Nm of torque, while meeting Stage V emissions standards. TThe decision to adopt the KDI engine series was based on several key advantages over the predecessor’s engine configuration. The KDI engines are particularly well-suited for transverse installation, which is essential for the machine layout. In addition, they fit seamlessly into the modular design concept of the machine portfolio, ensuring flexibility and compatibility across different models. Another decisive factor was the compact design of the KDI engines, allowing for more efficient use of installation space. Compared to the previous engine generation, the KDI series also provides higher torque while delivering lower fuel consumption and reduced noise emissions.
