“I’d say to anyone looking for a nimble, powerful machine that’s easy to transport and a breeze to operate, this is the dozer for you,” said Jonathan Tolomeo, Komatsu product manager.

“Residential and commercial development, highways, golf courses – the D39EX/PX-24 gets it done on any of these light-to-medium dozing and fine grading applications and more,” Tolomeo said.
