The old saying "An Ounce a Prevention is worth a Pound of Cure" or "Pay Me Now or Pay Me Later" go hand in hand with Equipment Care & Maintenance. We know tractors work in a tough environment but at the minimum an annual cleaning will help increase the longevity of your investment.
* Dirt, Grime and Residue reduce the ability and performance of your equipment. Engines, Transmissions, and Hydraulic Systems create heat and that heat has to be removed to increase the life of those components. Dirt & Grime covering the housing reduce the effectiveness of the removal of heat from those components. Dirt and Grime act as insulation and help retain heat versus allow for it to be removed. Been Trying to Research the Insulation Value of and have not found a reliable study yet but know it increases or retains heat. And Heat is not good for Engines, Hydraulics or Transmission Systems.
* Retains Resale Value...a clean tractor reduces the damage from moisture and rust and helps retain the Paint Quality...thus retaining the resale value of the equipment or added cost to repaint or replace rusted components.
* Premature Failures: Dirt & Residue build-up can increase the odds of failure of components adding additional maintenance costs.
* Oil Contamination: Keeping the Fill Points Area Clean will reduce the chance for dirt and grime to fall inside the system when adding fluids. At minimum reduces need to change plugged filters.
