Disc Blades
1. The Tilloll is equipped with full concavity disc blades.
These blades measure 20" in diameter and have 2"
of concavity. The very outside blade on both sides of
machine is a 20" diameter coulter blade.
2. The use of other concavity blades can give
unpredictable results and is not recommended.
Disc Gang Assembly
1. The disc gangs are assembled using 1-1/2" diameter
gang shaft. Spring-loaded end collars are used on
each end of the disc gangs to maintain clamping
force of the gang shaft. Slotted hex nuts are installed
at both ends of the disc gangs to allow service from
either end.
2. When disassembling a disc gang, note the locations
of the bearings and tapered blades. Remove the 3/8
cotter pin from the end of the gang shaft and clean
any remaining soil or debris from the gang shaft
threads. Closed-end gang shaft wrenches are
provided on the center frame to fit the gang nuts. An
additional extension or cheater pipe may be required
to loosen the gang shaft.
3. When reassembling the disc gang, remove any soil
or mud from the disc blades and spools to ensure a
clean surface when tightening the gang.Clean the
gang threads and install the gang nut. Torque the
disc gang shaft to a minimum of 1200 ft-lbs
Figure

Disc blades are extremely sharp. Exercise
extreme care when working on or near disc
blades. Do not allow discs to roll over or fall onto
any bodily part. Do not allow wrenches to slip
when working near disc blades. Never push
wrenches toward disc blades. Do not climb over
machine above disc blades. Failure to stay clear
of disc blade edges can cause serious personal
injury or death.
