First in new line of dozers features high-performance hydraulics

The Case 1650L crawler dozer is the first model in the company’s new L Series dozer line. Innovative features include added power and performance, thanks to a 144-net-horsepower (107kW) electronic Tier III certified engine, an electronically controlled variable-displacement dual-path hydrostatic transmission, and an eight-roller undercarriage with a hunting tooth sprocket for precise and easy grading. “The 1650L is a completely new machine from the ground up,” said Jim Hughes, marketing manager, Case Construction Equipment. “In addition to the powerful engine and hydrostatic transmission, it features a new cab design, low-effort electronic blade control and high-performance hydraulics for increased blade speed, superior blade force and precise control.” The hydrostatic drive features electronic straight tracking with counter rotation and selectable settings for shuttle and steering for slow, normal and fast control reaction. There are 10 speed settings with infinitely variable steering for maximum maneuverability with counter rotation. A variable displacement, dual-path, hydrostatic drive makes for high tractive effort. An optional winch drive (hydraulic equipment pump with through shaft) is available.

According to Hughes, the operator can maintain power to both tracks while turning and can push a full load through a turn without losing control of the load, braking or raising the blade. “Our customers find it’s an ideal machine for residential and commercial construction, roads and bridges, and utility applications,” Hughes said.

Operators can also adjust the sensitivity of the steering and the forward/reverse modulation to suit personal preference or application conditions.

To boost productivity, the 1650L provides low-effort electronic blade control for simultaneous, multifunction control. The operator can pitch the blade to match the material being worked. The high-performance blade hydraulics have large cylinders that deliver speed and power for optimum control and blade force.

A narrow, modular dashboard gives the operator a direct line of sight to the blade’s cutting edge, and the tapered hood and cowl on the 1650L allow for excellent visibility so it’s easy to gauge material flow under the blade. The cab is isolation-mounted from the main frame to cushion against noise and vibration, making for a comfortable ride. The deluxe cab features heat and air conditioning for year-round, climate-controlled comfort.

The undercarriage has an eight roller track frame for precise, easy grading. Pinned equalizer beam suspension makes for a smooth ride, maximum traction and positive track alignment. Two track frame-mounted carrier rollers maintain proper track tension. A 49-degree sloping track frame cover, along with ample space between the track and the machine, helps shed material.

Operating weights on the 1650L are 35,203 (15,965 kg) on the XLT, 36,691 pounds (16,640 kg) on the WT and 37,578 pounds (17,042 kg) on the LGP. The XLT is ideal for precision grading. The WT provides extra stability and accommodates wider blades for finish grading or slope work. The LGP maximizes flotation in wet or loose soil conditions.
