Do bigger jobs always require larger or multiple machines? What if you could get the same amount of work done with a mid-sized dozer that allows you to push large loads while also giving you the ability to get to finish grade? How much savings in time, owning and operating costs would that give you?
“These are considerations you should take into account when approaching every project,” said Jon Jennings, Komatsu Product Marketing Manager. “Choosing the right machinery makes a significant difference in production, efficiency and profitability. A single dozer that can push, side cut, finish and work in soft ground gives you a real advantage.”
Jennings added that technology such as GPS systems can make the dozer and the operator even more effective at moving dirt productively and efficiently. These systems decrease the time it takes to get to grade, which reduces staking and surveying costs, and virtually eliminate overcutting and the need for expensive fill.
“GPS systems and additional technologies continue to reduce owning and operating costs,” stated Jennings. “They are also helping new operators become productive faster. With a shortage of skilled operators, that’s a tremendous help.”
Manufacturers such as Komatsu are factoring in all of these needs as they design and build new machines, according to Jennings. Komatsu introduced its first intelligent Machine Control (iMC) dozer with factory-integrated GPS about eight years ago and has developed several new models with additional technology since. This includes their new iMC 2.0 models with added satellite systems to improve satellite coverage – which gives operators the ability to work in more challenging areas, such as near woods or on urban job sites.
The newest iMC 2.0 D71EXi-24, D71PXi-24 and D71PXi-24 Wide dozers combine several features designed to further increase production. Among them are:

The new D71i-24 intelligent Machine Control 2.0 dozers feature the super slant nose design that offers outstanding visibility to the cutting edges. “Seeing the front of the machine with reduced blind spots increases awareness of the job site,” said Jon Jennings, Komatsu Product Marketing Manager.
Jennings said visibility plays an important role in operator productivity. Being able to see the blade’s cutting edges increases production, especially during fine grading work near curbs. The D71i-24 is now the largest of Komatsu’s hydrostatic dozers, and it maintains the unique super slant nose design.
“Seeing the front of the machine with reduced blind spots increases awareness of the job site,” said Jennings. “That’s important when running a large machine such as the D71, which has the biggest standard blade in its class size. It increases operator confidence and, in turn, their ability to be more productive.”
In addition to the iMC 2.0 D71i-24 models, base D71-24 dozers are also available. EX dozers have a ground pressure of 6.3 psi. With a ground pressure of 5.8 psi, the PX models work well in soft conditions; and for highly sensitive areas, PX Wide models with a ground pressure of 5 psi are available.
“With the D71-24s, we specifically matched the track shoes’ width to the blade length to ensure optimal performance,” said Jennings. “Additional new performance features include improved steering response and maneuverability. In the new Fast Mode during turns, the outside track speeds up while the inside track slows down.”
“From golf course construction to highway projects, the D71-24s are all-around crawler dozers,” said Jennings. “Equally adept at both precise, high-speed grading and at rough dozing, they are designed to provide outstanding wearability and functionality with a high-capacity, wear-resistant dozer blade. We encourage anyone looking for a solid mid-sized dozer with the versatility to perform on practically any job site, to contact their distributor to set up a demonstration.”
New technology combined with integrated intelligent Machine Control allows automatic grade control from rough cut to finish grade on a wide range of job sites. “Choosing the right machinery makes a significant difference in production, efficiency and profitability. A single dozer that can push, side cut, finish and work in soft ground gives you a real advantage," notes Jon Jennings, Komatsu Product Marketing Manager.
