The Caterpillar designed and manufactured drive has four heavy-duty rotary axes (concentric, buffered by elastic material Pipes). This extremely durable axes move independently, so that the frame of the drive is isolated, and absorb a large part of the driving shocks in the operation. The customer learns the benefits of drive suspension by a quiet even at high speed ride that through the excellent material retention, increased performance and longer life of the machine and drive components. Two two-stage high performance hydraulic motors drive the planet side-drives of the 259 B 3, and it passed the power on one-piece steel sprockets. The hydraulic pump for the working hydraulics (boom and bucket) and the auxiliary hydraulics (drive by work equipment) 259 B 3 directly from the motor are driven. This guarantees highest efficiency, performance and reliability, because additional transmission belt eliminates the need. The powerful auxiliary hydraulics system offers an oil flow rate of up to 83 l/min (22 gpm) at a pressure of up to 23,000 kPa (psi 3335), yielding a hydraulic rating of 31.9 kW (42.8 HP) is created. Tracked loaders is also equipped with cat ToughGuard XT hydraulic hoses that are particularly resistant to wear and the extra hydraulic lines (with flat HD couplings) are mounted on the lifting arm.

Also an equipment change facility is among the standard equipment and is optional to have a hydraulic quick change facility. The spacious driver’s cab designed for comfort, ease of use and security of the 259 B 3 has smooth, pilot-operated control lever. With the control levers, the auxiliary hydraulic functions can be controlled exactly. Des are further standard equipment hand throttle and accelerator, with which the 259 B of 3 on the operation with fixed speed (for example, to the Grabenziehen or milling) or with adjustable speed (for the loading of trucks or loading and support) can be adjusted. Also a simple maintenance is the new compact tracked loaders: the tailgate can be namely on, thus the motor from both sides as well as all Routine maintenance points are accessible. A unique, high tilting cooling package allows a quick cleaning of engine and oil cooler, and the driver’s cab can be highly tipped, which then all main hydraulic components and cables are accessible.
