RT-75 Posi-Track compact track loader offers versatility with its high ground clearance, low ground pressure and superior traction for a variety of conditions, from fragile turf, mud and wet ground to slopes, ice and snow.
ASV LLC, a manufacturer of all-purpose and all-season compact track loaders and skid steers, introduces the large-frame, radial-lift Posi-Track RT-75 compact track loader. The RT-75 features highly efficient hydraulics and a high capacity cooling system while delivering superior serviceability. ASV's Posi-Track undercarriage provides high ground clearance, low ground pressure, best traction and longest track life. These features make the compact track loader the ideal machine for applications from construction, landscaping and agriculture to forestry, snow removal and more, according to the manufacturer.
“ASV is on a mission to revolutionize the compact track loader market,” said Jim DiBiagio, ASV general manager. “When ASV launched our new lineup of compact track loaders the goal was simple: maximum performance — no compromises. The RT-75 was designed to be the most reliable, highest all-around performing machine in the large frame class — 75 to 95 horsepower machines. We use high-quality components from well-known suppliers — Cummins engines, Bosch drive pumps and motors, and Interstate batteries, to name a few. When you couple high-quality components with over 25 years of experience designing compact track loaders, you get a machine that delivers on our promise of maximum performance with no compromises.”
The RT-75 is a new compact track loader ASV built from the ground up, starting with the undercarriage. The machine features ASV's Posi-Track rubber track suspension. Well known for its smooth ride, the dual-level suspension of the RT-75 features both suspended wheels and axles, allowing it to manage every type of terrain and at faster speeds. The suspended wheels and fully-flexible track conform to the ground assuring maximum traction in the roughest conditions. In addition, the multiple wheel contact points and triple-guide lugs — compared to many machines with only one or two guide lugs — achieve maximum performance on steep slopes.
The RT-75 comes standard with 18-in. (45.7 cm) wide tracks, resulting in a ground pressure of only 3.6 psi. Optional 20-in. (51 cm) tracks lower ground pressures to 3.2 psi. The features, combined with the RT-75's nearly 15 in. (38 cm) of ground clearance, allow the unit to work in more places, on more days and more comfortably than other machines, according to the manufacturer.
The ASV undercarriage has undergone a complete transformation from a closed design — similar to those used on steel-embedded undercarriages — to an open-rail and drive-sprocket design. The change increases sprocket and bogie life and makes the undercarriage easier and faster to clean. ASV manufactures all rollers with mechanical face seals that don't require maintenance for the life of the machine. The tracks contain embedded co-polymer cords for extra strength and are produced using a single-cure process, eliminating cure-point weaknesses in the track that can lead to premature breakage. The result is a 1,500- to 2,000-hour track life — 30 percent more than steel-embedded track units. ASV backs that up with a two-year, 1,500-hour track warranty.
The RT-75 features a Cummins 2.8-L turbocharged diesel engine. The 75-hp engine produces 221 ft.-lbs. of torque — 13 percent more than the machine's 80-hp predecessor, the PT-80. The torque is transferred to the ground through direct-drive hydraulic motors. There is no need for servicing because the RT-75 does not use planetary drives, and the highly efficient motors transfer maximum power to the patented internal-drive sprockets. With internal rollers preventing friction loss in the undercarriage, all power is transferred to the track regardless of drive speed.
The RT-75 achieves Tier IV Final compliance using a diesel oxidation catalyst that requires no regeneration, no sensors, no diesel exhaust fluid, less wiring and no additional maintenance. ASV designed the machine with serviceability in mind, giving operators easy access to the reliable Cummins engine through a three-panel hood and tilting cooler arrangement. The design, paired with sight gauges for both hydraulic oil and coolant, simplify routine inspections of filters, oil and normal service items. The rearward tilting cab provides easy accessibility when further service is required.
ASV built the RT-75's auxiliary hydraulic system to be highly efficient, including 35.7 gpm (135 Lpm) high flow and 3,300 psi. Because the machine includes larger line sizes, hydraulic coolers and direct-drive pumps — rather than belt-driven pumps, preventing power loss — more flow and pressure is transferred directly to the attachment. This allows operators to run attachments, such as brush cutters and mulching heads, more efficiently than higher-horsepower machines from other manufacturers. As a result of belt-driven pumps and restrictions in their hydraulic systems, many competitive machines lose as much as 30 percent of the horsepower that is shown on their spec sheets. Conversely, the RT-75 achieves 22 percent more actual hydraulic horsepower than the 80-hp machine it replaces, according to the manufacturer.
The RT-75 features a rated operating capacity of 2,650 lbs. and a tipping load of 7,571 lbs. It is 70 in. (178 cm) wide and has a 126-in. (320 cm) lift height. Standard joystick controls make operation easy and intuitive. It comes with an optional all-weather cab that includes heat and air-conditioning and is pressurized for a clean operator environment.
The RT-75 also is available in a heavy-duty customization package that includes guarding around areas such as lights, the AC condenser and the rear screen. The RT-75 Heavy-Duty uses a hydraulically driven, auto-reversing cooling fan, similar to the fan used on the RT-120 Forestry, to blow debris out of the engine compartment screens. A full rear brush guard also is available as a factory installed option. The unit can be paired with all standard attachments, such as backhoes, buckets, snow blades, brush cutters and pallet forks.
“Our goal at ASV is to provide our customers versatile equipment they can use for everything, regardless of the time of year, to achieve a high return on investment,” said Bill Wake, ASV director of product development. “The RT-75 lets our customers work longer days, tackle more applications and reduce maintenance. That's a winning combination. We really focus on maximum performance with no compromises and the RT-75 delivers.”
