blizzard."

Gregg Zupancic, John Deere, indicates about half the loaders the company sells go out with a cab option that includes heat/defrost and/or air conditioning. And that number keeps going up, especially in larger models where contractors feel they can better afford to splurge.

"They can operate in all weather conditions," he says. "If it's raining, they can continue to work. The same can be said for working in dusty and snowy environments. Without a cab, they may have to take a day off. Contractors can justify the added expense with more productivity."

Enclosed cabs also offer a cleaner, quieter work environment by minimizing dust and significantly lowering the noise level.

Many manufacturers offer sound-proofing options to further maximize noise reduction. For example, the optional acoustical kit offered by John Deere reduces noise by about 5 dB, which makes it more than 50% quieter than the same skid steer without the kit. The $140 option (list price) includes a better headliner and additional sound reduction materials throughout the cab interior, absorbing noise and more effectively separating the operator from the engine compartment.

In addition to reducing operator stress and fatigue, a quieter cab facilitates use of options such as radios and MP3 players. "Twenty years ago, you didn't need a radio because the machine was too loud to hear it," says Hughes. "Now, technology has progressed to the point where we're able to quiet the machines. Operators want to listen to music. It keeps them going through the day. It goes back to those creature comforts of your home and your car that you want in a loader."
