ALL WHEEL DRIVE.ALL WHEEL PERFORThe Cat ® 140M, including theindustry-leading All WheelDrive system, delivers greatermachine versatility, utilisationand performance.Around Australia, there are now onethousand Cat ® M Series Motor Gradersbeing put to work. We’re proud of thismilestone but remain focused on continuingto deliver technology innovations that makeoperators more comfortable, worksites moreproductive and businesses more profitable.M SERIES. 1000 AT WORK.All Wheel Drive (AWD) is a must havefeature for those who work in traction-limitedconditions such as mud, sand, gravel, or snow.An AWD system can also be beneficial onside slope applications, where the additionaltractive effort can help keep the grader fromsliding off the intended line of travel.AWD can boost performance with addedversatility, stability, and an overall increase inpower and torque. The Cat AWD variable frontdrive motors powered by separate dedicatedleft and right hydraulic pumps provide theproper match between torque and speed, sowhen operating in the lower working gears,you will have over 50% more torque than theprevious Cat H Series. If working in a highspeed, loaded condition, you will still havethe necessary pull to power through heavyunderfoot and/or hilly terrain, due to the infinitevariable ratio between torque and speedthroughout the forward and reverse gear range.The Cat AWD infinitely variable pumpsand motors maximise torque in each gearand deliver maximum power to the ground,increasing productivity.
