Maneuverability has become increasingly important as the size of job sites has reduced – the agility of the smaller-size dozer is essential. Applications where he sees continued growth in this category include residential building, commercial construction, landscaping and agriculture. These machines are also ideal for working on job sites where space is limited, and maneuverability is critical," says Dulak. Grading and sloping, backfilling and land clearing are typical applications. "Maxing out at over 41,000 pounds of drawbar pull, CASE dozers in this size category are very versatile, with the ability to move a lot of dirt and perform finesse jobs like fine grading. Applications for small dozers under 25,000 poundsĪs job sites get smaller or harder to access, smaller dozers are seeing growth in a range of applications. The versatility of the small dozer makes it ideal for satisfying many of today's infrastructure jobs, such as road widening, and Joel Fritts, product application specialist for small dozers with Caterpillar, attributes their increase in popularity with not only that road construction work, but also with residential jobs and other types of general construction that are often needing to be done in a shrinking footprint. In this size class customers are asking for machines that are simple to operate with technology to enable operators to stay comfortable and productive." Andrew Earing, senior product manager with Komatsu, agrees, and says that when it comes to features, machine control is seeing steady growth as customers seek more efficient solutions for their work that can increase their profitability. "When we think about challenges our customers face, it's common to hear about the shortage of skilled operators. Machine control and other integrated technologies are going to be a big part of the future." Matt Goedert, solutions marketing manager, roadbuilding, with John Deere Construction & Forestry, agrees that technology is part of the solution as the workforce changes. "Operators need a machine that they can get in and learn fast. The key trends that are driving innovation in the small dozer category are primarily centred around operator experience and efficiency including comfortable cabs, easy-to-use controls and operation settings that maximize production. According to Jeremy Dulak, product and marketing manager, dozers, with CASE Construction Equipment, the small dozer market is the largest size class in the industry and continues to grow. Our panel of industry experts highlights how going smaller, where possible, can yield great results for many applications, such as road widening, brush clearing, and residential and general construction. Like their larger counterparts, smaller-size dozers under 25,000 pounds deliver considerable pushing power and can be outfitted with the latest in machine control technology, but they have some advantages: easier transportation ability to fit into narrower areas, such as the lane of a road and lower operating costs. A total of 26,454 D2's were made over the nineteen years they were in production.As working space has become smaller and efficiency needs have become greater on a range of construction sites, deploying powerful but smaller equipment is a must and can maximize efficiency in a range of jobs. Caterpillar began producing this model (among others) in response to the "New Deal" programs that were initiated by President Franklin Roosevelt to stimulate America's economy. The D2's weight ranges from about 7,420 to 8,536 pounds (3,366 to 3,872 kilograms), depending upon the year it was manufactured. The base frame of this model of tractor is a crawler, and it is equipped with five forward gears and one reverse gear. in their factory in Peoria, Illinois, USA. The Caterpillar D2 was manufactured from 1938 through 1957 by Caterpillar Inc. It was introduced in 1938 and was the smallest diesel powered track-type tractor manufactured by Caterpillar. The Caterpillar D2 is an agricultural tractor manufactured by Caterpillar. Caterpillar D2 compact crawler tractor (built from 1938–1957) at the Belvoir Castle Steam Festival 2007, Belvoir Castle, England.
