The Case 650L crawler dozer delivers 74 net hp through a proven, four-cylinder, 4.5-liter Case Family IV engine. Operating weights range from 16,250 to 17,550 pounds. Low operating height allows the 650L to work around low overhangs, while its lighter weight is ideal for work in soft soil conditions. The short track means easier turning and maneuverability on the job site. The compact size also makes the crawler dozer easy to transport from job to job. 866-54CASE6, casece.com

Caterpillar
Cat_equip spot1.jpg
The D9T is powered by a Cat C18 engine with ACERT Technology, rated at 410 hp with an operating weight of more than 110,000 pounds. A low-effort electronic dozer control handle gives the operator control of all dozer functions with one hand. Operators will enjoy adjustable arm rests, new automatic climate control and the standard Cat Comfort Series Seat now available with optional heat and ventilation. The new Dynamic Inclination Monitor provides readouts of the tractor's pitch angle and side-to-side slope. In addition, a new operator-presence system locks out the power train and hydraulic system to avoid unintentional machine movement when the operator is entering or leaving the cab, assisted by redesigned steps, handles and guardrails. An optional Automatic Ripper Control simplifies the operator's job by keeping drawbar load constant and minimizing track slip. In addition, Automated Blade Assist uses blade-pitch presets to simplify positioning, and an optional Autocarry system automatically adjusts blade load during the carry segment. cat.com/D9T
