centre load-sensing main control valve. This ensures that sufficient flow is always available. Ease of operation and maintenance Both the Cat 150 AWD and the SDLG G9290 place greater focus on ease of operation and ease of maintenance, based on the two OEMs’ understanding that these are significant parameters as far as productivity is concerned. With large openable doors at the side and at the rear, the SDLG G9290 motor grader provides greater access to all the main maintenance points. For convenience, all filters are grouped together on the left side of engine. “The new SDLG G9290 motor grader is the embodiment of Reliability in Action,” says Jammoul. “The machine is built to last, while delivering best-in-class grading performance.” With ease of operation in mind, the Cat 150 AWD’s Selectable blade lift modes – Fine, Normal, or Coarse – allow the operator to choose the blade lift modulation mode that best fits your application or operating style. Joystick controls with electronically adjustable control pods reduce hand and

lights to ensure safe operation even in the absence of daylight. “The design of the G9290 provides greater visibility for the operator to the front and the sides of the machine, with large windows to enhance all-round visibility. The sloping front frame provides sound visibility to front objects. Inside the cab, the low efforts control levers are ergonomically laid out with ample adjustment possibilities to fit every operator’s needs. The steering wheel pedestal is also adjustable for optimal comfort,” says Jammoul. To increase operator comfort, the Cat 150 AWD’s control pods can be adjusted electronically, making it easy to set to ideal operating position. The standard Cat Comfort Series suspension seat is fully adjustable. The high-capacity heating, ventilation and air conditioning (HVAC) system dehumidifies and pressurises cab, sealing out dust and helping keep windows clear. With safety in mind, the 150 AWD’s angled cab doors, tapered engine enclosure and sloped rear window make it easy to see moldboard and tyres, as well as behind the machine. The optional rear vision camera enhances sight to rear of machine. b

The 150 AWD’s left joystick controls steering, articulation, return-to-centre, wheel lean, gear selection, left moldboard lift cylinder and float. The right joystick controls drawbar, circle and moldboard functions as well as electronic throttle control and manual differential lock/ unlock. The articulation Return-to-Centre automatically returns machine to a straight frame position from any angle with the touch of a button. As far as serviceability is concerned, the Cat 150 AWD comes with sacrificial brass wear strips between blade mounting group and moldboard, which can be easily adjusted and replaced. The Shimless Moldboard Retention System uses vertical and horizontal adjusting screws to keep moldboard wear strips aligned for reduced blade chatter and precise blade control. Safety and comfort The G9290’s cab is fitted on the front frame of the machine to reduce vibrations and heat from engine and transmission. Entry and exit can safely be made with three-point contact all the way. The cab is fitted with LED work
