Bobcat Company released its first Tier 4-compliant 700 frame-size loader. The S740 is powered by an engine that is under 75 horsepower and doesn’t require a diesel particulate filter (DPF), selective catalytic reduction (SCR) or diesel exhaust fluid (DEF).
Bobcat S740 skid-steer loaders use a diesel oxidation catalyst (DOC) to meet Tier 4 emission standards, but without the need for a DPF. The DOC is a special catalyst that reacts with engine exhaust upon contact and transforms combustion byproducts into substances like water and carbon dioxide. The Tier 4-compliant 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, according to the OEM, enabling Tier 4 emissions compliance without using a DPF.
The S740 joins the M-Series line, which includes 11 skid-steer models.
A vertical-lift-path machine, the S740 loader can lift loads higher, making it easier to clear high-sided truck boxes and hoppers.
The hydraulic systems on M-Series loaders also have higher standard flow and pressure, providing for increased attachment performance. An optional high-flow hydraulic option of 30.5 gpm gives S740 operators more attachment power.
Like all M-Series skid-steer loaders, the S740 features a cab-forward design that moves the operator closer to the attachment and provides optimal visibility in all directions. The new loader has a large cab door opening, offering superior visibility to attachments and particularly to the cutting edge and corners of a bucket.
Windows on the sides and rear of the cab are larger in size to provide more visibility to the tires and back of the machine. The larger top window is designed to make it easier and more comfortable for the operator when performing tasks like loading trucks or tall hoppers.
The S740 features a large, pressurized cab with a one-piece seal that goes all the way around the door and fits into a special curved pocket. This minimizes the amount of dirt and dust that might enter the cab, creating more enjoyable working conditions and making it easier to clean the cab.
Operators also have the choice between standard foot pedal hydraulic controls, the Advanced Control System (ACS) or the Selectable Joystick Controls (SJC).
The S740's auxiliary quick couplers are mounted directly to the front plate of the lift arm to provide a solid mounting, and hoses are routed through the loader arms for better protection. A guard bar extends in the front of the coupler for added protection.
Keeping the loader cool when working long hours also helps prolong service life of the machine. The redesigned cooling system on the M-Series S740 allows for increased efficiency, is easy-to-clean and increases machine performance.
