3.3.3 Protective Coatings
There are no special requirements for protective coatings on the hydraulic systems of a Toomey
Scraper. The only consideration is to keep the steel hydraulic lines free from dirt and debris for
extended periods of time as the moisture in the dirt and debris can promote accelerated
corrosion of hydraulic lines.
If the hydraulic lines develop a red oxide layer as opposed to the white zinc
oxide then the zinc layer has been eroded and the steel of the hydraulic line
has been compromised. The hydraulic line affected must be replaced.
3.4 Tractor Specifications
The tractor manufacturer defines the maximum drawbar weight and permissible load on the
tractor. Consult your tractor dealer to select the ideal tractor for your scraper which does not
exceed the limits set by the tractor manufacturer. The information listed above can be used to
check that the tractor is not overloaded and potentially void any warranties of the tractor. Also
check that the tractor pulling capacity does not exceed the limits of the Scraper as this could void
the warranty of the Scraper against structural defects and damage.
