With the coldest months of the year just around the corner, it's time to examine how your backhoe rental fleet will fare and to ask yourself: am I winter-ready?

If your answer is maybe, perhaps memories of winter's worst will inspire you to get going with some basic seasonal preventive maintenance. Here are some tips to help you get started:

* Change the oil and oil filter before cold weather arrives. Use the proper viscosity oil recommended for winter operation.

* Inspect dry element-type filters - clean or replace if clogged with dust or dirt. Inspect for damaged seams and pleats, and replace if necessary.

* If the backhoe will be operated in blowing snow, consider a pre-cleaner on the air-intake system. This attachment prevents blown snow from entering the air-cleaner element, which could result in loss of power, excessive fuel consumption and possible oil consumption.

* Maintaining the proper mixture of antifreeze and water is mandatory for proper cooling system operation in subfreezing temperatures.

* Before cold weather develops, drain the cooling system. Replace cracked, soft or swollen radiator hoses. Check thermostats for proper operation.

* Clean dirt and trash from the radiator fins and inspect the surrounding baffles and fan shroud to see that they are in place and functional.

* Fill cooling system with proper mixture of clean water and permanent antifreeze with an ethylene-glycol base. The solution should be adequate to protect to the lowest temperature expected.

* Inspect belts and replace those showing damage or excessive wear. Check for proper belt tension to ensure proper coolant and air flow.

* Check the condition of batteries and cables. Clean and inspect battery posts and cables ends; clean and tighten terminals on the starter motor.

* Test the engine coolant heater to ensure that it works properly. If unequipped, consider installing one.

* Tighten connections on the cold-weather starting aid, inspect the line for kinks and clean the starting-fluid spray orifice.

Non-engine components Although engines can account for a number of cold- weather woes, other components also should receive your close attention.

* Transmission and hydraulic system components, hoses, lines, and connections should be examined for external leaks or damage.

* Drain and refill oil and filters, using winter-grade oils if required for specific applications.

* Check oil for excessive contamination and metal particles.

* Inspect and clean breathers.

* Check tires and rims for damage. Tires with nicked or bent rims may retain air during warm weather, but often leak in subzero temperatures.

* Replace broken windows and seals around doors. Replace windshield and rear -window wipers.

* Check operation of the heater and defroster.

* Make sure all lights, turn signals and warning lights operate properly - especially if the machine is to be used for snow removal.

Specing new machines If you are adding new backhoes to your fleet, give serious consideration to the many cold-weather options that are available. Spending a little extra money now may make a big difference in utilization. In addition to making your backhoe more winter-weather capable, numerous accessories and attachments can widen its year-round appeal as well.

Many manufacturers offer a cold-weather package that includes engine coolant heater, ether-start aid and dual heavy-duty batteries. These accessories help backhoe engines start easier and with less strain. And they can mean the difference between a machine that doesn't work and one that works.

For icy or muddy conditions, all-wheel drive is a popular and practical option. Not only does it add traction and control on slippery surfaces, but it also enhances productivity in normal working conditions.

When it comes to cold-weather operator comfort, there are several ways to make winter work more tolerable:

* Obviously, a heated cab is the best option. However, short of that, an underseat heater is a welcome addition that will help keep a chill off the operator's feet.

* Cell-phone power ports and weather-band radios are also appreciated extras, especially when the machine is being used for plowing snow.

* Cold-weather attachments such as snow basket loader buckets and narrower backhoe buckets are ideal for a variety of winter uses.

* Changing the teeth on the buckets can also make a difference. Offer frost teeth, as well as couplers, for your bucket attachments.

* An extendible dipperstick can also prove profitable, increasing digging depth, reach and the machine's all-around performance capabilities.

Take time today to ensure that your backhoes are ready, able and willing to face winter's worst, and you will be rewarded with a highly rentable fleet that will be "in season" year-round.
