Bobcat has released its first Tier 4 600 frame-size loaders: the S630 and S650 skid-steer loaders and the T630 and T650 compact track loaders.
The 600-platform loaders were the first Bobcat M-Series loader models introduced, setting the pace for greater productivity due to their enhancements in operator comfort, hydraulic power and easier serviceability. Bobcat says these four 74-hp loaders provide operators with all of the same performance benefits of the previous interim Tier 4 models and meet emissions standards without a diesel particulate filter (DPF).
The Tier 4 Bobcat non-DPF solution was achieved by designing an ultra-low particulate combustion (ULPC) engine. The ULPC is accomplished through a specially designed engine combustion chamber that significantly reduces the amounts of particulate matter created during combustion. Therefore, Tier 4 emissions compliance can be achieved without using a DPF.
In addition to eliminating the need for a DPF, the new engines used in 600 frame-size loaders will have increased torque. This increase in torque is produced over a wide range of engine rpm, allowing operators of all skill levels to better utilize the machines’ maximum performance.
