Bobcat M Series Skid-Steer Loaders

August 2009 Vol. 64 No. 8
The Bobcat S360

Since inventing the skid steer loader more than 50 years ago, Bobcat has constantly improved loader design to make operators more productive and comfortable.

New Bobcat M Series skid steer and compact track loaders feature the most significant design changes undertaken by the company. This new design enables the operator to accomplish more work through performance and durability enhancements that provide more power and keep the loader working longer, while increasing operator comfort through improved visibility and a more spacious and comfortable cab.

The first M Series models are the S630 skid steer loader and the T630 compact track loader. The S650 and the T650 will be available in August and additional models will be available in the future.

The S630 has a rated operating capacity (ROC) of 2,180 pounds and an operating weight of 7,707 pounds. The S650 has a ROC of 2,690 pounds and an operating weight of 8,327 pounds. The T630 has a ROC of 2,230 pounds and an operating weight of 9,015 pounds. Finally, the T650 has a ROC of 2,570 pounds and an operating weight of 9,440 pounds.

The hydraulic systems on M Series loaders have been engineered for higher standard flow and pressure that give attachments more power to work more quickly. Hydraulic horsepower has been increased more than 15 percent and the standard auxiliary hydraulic flow is now 23 gpm at 3,500 pound per square inch and an optional high flow reaches 30.5 gpm for maximum attachment performance.

A removable hydraulic hose guide makes changing attachments easier and correctly routes the hoses, preventing wear. The guide slides onto attachment hoses and is easily attached to the loader during attachment hook up. The operator does not have to twist or bend hoses. Attachments approved for use on M Series loaders have a post for the removable hose guide that keeps the hose secure, clean and protected when the attachment is not in use.

More power
Other performance enhancements include an increase of the tractive effort of M Series loaders by 15 to 20 percent to provide exceptional pushing and digging power; holes for frame mounted counterweights that increase lifting performance with certain attachments; and a larger fuel capacity that allows the loader to work longer between fueling.

The hydraulic quick couplers are now mounted directly to the front plate of the lift arm. A guard bar extends out in front of the coupler for added protection.
