Introduction
The GAPCR-HD 8013 disk harrow is specially designed for
hard-working, either in newly deforested areas or sugar cane
ratoons.It is great for seedbed preparation in large areas after the
crop and stubble incorporation.
The GASPCR-HD 9017 disk harrow is specially designed to
prepare the soil deeply and to harrow newly deforested areas and
extreme conditions in civil construction, like roads and dams.
The GASPCR-EHD 10020 disk harrow is specially designed to
build roads and dams in severe conditions, harrow newly deforested
areas and savannas; as well as to eliminate the ratoons with a
great straw concentration.
All models feature an efficient wheelset with hydraulic activation
to control the depth and transport the equipment safely over long
distances. This wheelset also streamlines the maneuvers during
the service.
This instructions manual contains the necessary information
for the best performance of these harrows. The operator must
carefully read the entire manual before working with the equipment.
Also, read and understand the safety recommendations.
For any further clarification or in the event of technical
problems that may arise during the service, consult your dealer
and the Technical Support department of the factory. They can
ensure the fully functioning of your TATU disk harrow.

on ditch banks, it may cause a serious accident.
• When lifting with a hoist, use the appropriate points to lift.
• Underpin the equipment appropriately.
• Use chock blocks and safety chains to secure the equipment to the truck or
trailer during the transport.
• Make sure the SMV (Slow Moving Vehicle) sign, and all the lights and reflectors
that are required by the local highway and transport autorithies are in place, are
clean and can be seen clearly by all overtaking and oncoming traffic.
• After 8 to 10 km transporting, please inspect the load condition. Repeat this
procedure every 80 to 100 km. Give more attention when transporting the
equipment on rough roads, slopes and other adverse conditions.
• Always be careful with the load height, especially when passing under electrical
power lines, bridges and others.
• Check all laws and regulations regarding the height limits and load width while
transporting the equipment on truck or trailer. If necessary use banners, lights
and other devices in order to give adequate warning to the other drivers.
