Introduction
The DODH-F 9009T disk harrow was specially designed to
prepare the soil over long areas, break the clods and level the soil
after the harrowing.
Equipped with bearings bathed in oil, reagreasable roller
bearings and duo-cone seals; they provide a greater durability. The
bearings have protection covers to protect them from the wear.
The transportation of this harrow is done by an efficient double
wheelset system, being one on the central frame and the other on
the lateral. This wheelset system also makes the operation easier
by its quick and precise working depth and facilitates maneuvering
during the job.
It has high-resistance disc blades and also furrow fillers on
the rear gang ends used to reduce furrows and to let the harrowing
uniform.
This instructions manual contains the necessary information
for the best performance of this disk harrow. 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.

trailer during the transport.
• 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 to the truck or trailer. If necessary use banners,
lights and other devices in order to give adequate warning to the other drivers.

Assembly
First of all, put the parts in a clean place to identify them easier. Check the parts using
the list that comes inside the packing box.
Using the set of wrenches
NOTE We recommend wearing gloves, especially while assembling the disc gangs.
Disc gangs assembly
Before starting to assemble the disc gangs, check the correct position of the bearings
and spacer spools, according to the following pages:
Use two box end wrenches (A) to tighten the nuts of the disc gangs, one to hold the
axle nut on one side while the other tight the nut to the other end, thereby preventing the
axle from rotating.
Use a 2.3/8" or 2.3/4" adjustment wrench (B) to tighten the leveling control.
Use a 3/4" L shaped socket wrench (C) to tighten the bearings.
Use a 1" L shaped socket wrench (D) to tighten the disc gang carriers to the frames.
Use the box end wrench (E) to tighten the nuts of the traction set.

IMPORTANT •Check the correct side of the bearings and spacer spools according
to the concavity of the disc blades.
Place the outer lock (A) along with the axle (B).
Then, place the lock nut (C) and nut (D).
Place the disc blades (E), bearings (F) and spacer spools (G), following the instructions
on pages 13 and 14.
Place the bolt (H), along with a spring washer and nut.
Use the wrenches (A) from page 12 to tighten the gangs, as follows:
1) Place one of the wrenches on the outer side of the gangs (locked side), supporting
it on the ground. (as shown on page 16).
2) On the inner side, use the other wrench and tighten the gangs to get maximum
torque.
3) To tighten, the gangs must remain underpinned with a piece of wood or another
object, preventing them from moving. (as shown on page 16).
Lastly, place the inner lock (I), lock nut (C-1) and nut (D-1), fastening with a bolt (H-
1), spring washer and nut.
