Keep tires properly inflated. Keep irrigation engines serviced and well-tuned. Make sure motors, switches and control panels are clean. Check connections to make sure they are tight, and lubricate moving parts that require it. Irrigate according to a schedule for more efficient fuel and water use.
Safety is always a factor with electric equipment.
Don't take chances with faulty connections, make potentially dangerous repairs, or cut corners that put your safety at risk. If in doubt, contact an electrical contractor for help. The major contributing factor to high heating costs is supply and demand. Supplies of heating fuels leading into the winter of 2000-2001 were unusually low because of mild winters and low demand in the preceding years. This factor, combined with the coldest December 2000 on record and sharply higher demand, resulted in major increases in fossil fuel prices, including home heating fuels.
