Features and benefits

Operator comfort

Bobcat has the best cabs on the market with the largest cab space in the industry, reduced noise and vibrations levels and offering better visibility. The threshold of the cab door has been lowered and the size of the cab door has been increased, making it easier for operators to enter and exit the cab.

Visibility

The new cab offers 30% more visibility all around the loader.
The 5 cm forward positioning of the cab places the operator closer to the attachment. Forward visibility is further enhanced thanks to a 45% larger door and a lower front cross-member on the cab.  Also contributing to improved visibility is a 50% increase in the output (total wattage) of the front work lights. There are two bulbs instead of one as in the past.

Performance & Applications

Traction on the new generation loaders has been increased by 15 to 20% to provide greater pushing and digging power. The ratios in the transmission were changed.

The standard flow hydraulic efficiency has been increased by over 30%, providing better attachment performance. Hydraulic flow has been increased by 11% or 9 l/min. At the same time, the pressure of the pumps has been increased by almost 14 bar. In addition, the back pressure of the hydraulic system has been reduced by 7 bar.

Reliability / Durability

The new generation loaders are built to work long hours on demanding jobsites.
The hydraulic quick couplers are mounted directly to the front plate of the lift arm. A guard bar extends out in front of the couplers for added protection.

Serviceability

For an easy daily maintenance, the swing-open tailgate and the transverse mounted engine provide one-sided serviceability. Cab tilt provides easy access to the hydraulics. All result in unmatched access to routine and long term maintenance points.
