“With the Yanmar-powered RT-40, we are doubling down on the machine’s performance, reliability and comfort, as well as making it easier for our customers to service the engine at ASV dealers,” said Buck Storlie, ASV Holdings product manager. “The RT-40 is already a staple due to its ability to bring more power and productivity to limited-space work that may otherwise have required a fence removal or needed to be done by hand.”
Power and productivity
The repowered RT-40 includes a more powerful new 38.2-hp Tier 4, 3-cylinder Yanmar engine, featuring a 48.3-inch width, an 8.4-foot lift height, a 931 rated operating capacity and a 7.1 mph top speed. The machine also boasts high tractive effort, pushing and digging power with ASV’s Posi-Power system. The RT-40’s quick attach fits a variety of attachments and works with an optional adaptor plate for full-sized or walk-behind/stand-on loader attachments. An idler wheels full-metal-face seal package increases the ROC to 1,008 pounds. In addition, the loader’s compact size allows it to be conveniently towed behind a 1/2-ton pickup truck.
The RT-40 comes standard with variable auxiliary hydraulic flow and can operate efficiently at a high auxiliary circuit flow rate, powered by 13.3-gpm of pump capacity and 3,000 psi of system pressure. Labor-intensive belt servicing is eliminated thanks to ASV’s signature use of a direct drive pump. This and the machine’s large line sizes and hydraulic coolers transfer more flow and pressure directly to the attachment to help prevent power loss.
The RT-40 is tested to operate at full load all of the time in ambient temperatures from -40 up to 118 F, according to the company.
Serviceability and reliability
The RT-40’s Yanmar engine can be serviced at ASV dealers.
Additionally, the machine is designed so operators can spend less time servicing it and more time productively on the jobsite. Its rear-tilting hood offers easy access to maintenance points, including filters, oil and fuel tank reservoirs, hydraulic and water separator drains and the battery.
The loader is built with a heavy-duty frame, drive table and axles. It features new wiring harness routing for additional durability. In addition, the drive hose routing and chassis sealing are designed for reduced rubbing, fewer line breaks and boosted hose longevity. Metal-face seals on the front and back ensure the drive hubs do not require maintenance for the life of the machine. An optional bumper or bumper and limb riser can help protect the machine in tough applications, such as rental applications.
ASV offers a two-year, 2,000-hour warranty, which includes a no-derailment guarantee and covers the tracks for the entire warranty period.
Comfort and ease of operation
Entry and exit are easier and operators have more hip room due to the new single-sided lap bar. Partially adjustable armrests and a tall cab improves comfort for operators of different sizes. The cab is also pressurized. Optional all-weather or cold weather cabs include heat and air conditioning. ASV also offers additional comfort features, including a cup holder, phone mount and DC outlet.
The RT-40’s cab features rollover and falling object protection.
Operation is easy and intuitive with a new 4.3-inch color display and standard hydraulic joystick controls. A new drive transmission allows for more precise control and fine-tuned operation.
The machine also includes visibility improvements over its predecessor. A new frameless front door includes floor-to-ceiling glass area. The cab’s large side and rear windows provide additional lines of sight. The bright rear LED light and adjustable front pedestal lighting. An optional backup camera is available to replace the standard rearview mirror for additional convenience and visibility.
Posi-Track benefits
ASV’s patented Posi-Track RT-40 has a 10.8-inch ground clearance. The unit can easily travel over rocks, logs, stumps and other obstacles.
ASV’s Posi-Track system features a flexible track and an open-rail and internal positive drive-sprocket undercarriage. Posi-Track loaders also have many ground contact points, spreading the machine’s weight evenly. As a result, the RT-40 features a low 3.5 psi ground pressure. Optional smooth turf tracks minimize the risk of damage underfoot even further. The low ground pressure also translates to more flotation and traction on steep, slippery and wet ground, and enhanced control and pushing capabilities.
