Rated operating capacity (ROC) refers to the maximum amount of weight a machine, like a Bobcat loader, can lift safely. Tipping load refers to the weight needed to lift a loader's back tires/treads off the ground. A loader's ROC is roughly half its tipping load. Bobcat 553 loaders offer a 950-pound ROC and 1,905-pound tipping load, compared to 2,050 and 4,100 pounds, respectively, for S205 loaders, and 3,000 and 6,000, respectively, for the S300 model.
While fitted with its standard bucket, Bobcat's 553 skid steer loader measures 107.3 by 49.4 by 72.5 inches, and offers a 12.3-inch reach at maximum height, while the S205 is 130.3 by 68 by 76.3 inches, with a 29.6-inch reach at maximum height and the S300 is 142.9 by 74 by 80.9 inches, with a reach at maximum height of 34 inches.
The engines in the Bobcat skid loaders are liquid-cooled and run on diesel fuel. The 553 loader has a 25 horsepower engine, while the S203 and S300 loaders have turbocharged engines that are 61 and 81 horsepower, respectively.
The Bobcat 553 loader features a hydraulic system that pumps at a rate of 11 gallons per minute (GPM). The S205 loader's standard-flow hydraulics pump at 16.3 GPM and its high-flow hydraulics pump fluid at 25.5 GPM. Standard- and high-flow hydraulics on the S300 model pump at rates of 20.7 and 37 GPM, respectively.
The Bobcat 553's operating weight is 3,704 pounds and it has a top speed of 6.4 miles per hour (MPH). Its fuel tank holds 10 gallons of fuel. The operating weight on the S205 is 6,242 pounds. This loader can travel at 7 MPH and features a 24-gallon fuel tank. The S300 loader's operating weight is 8,140 pounds, and its tank can hold 25 gallons of fuel. Two-speed S300 loaders can travel forward at a maximum speed of 12 MPH.
