gangs are set 3 degrees higher than the
rear disc gang angles
Disc Harrow does not penetrate
soil properly.
Disc gangs are not set at enough angle.

loose or are bending.
Disc components are not sliding on axle
giving a false sense of tightness
Check fit-up of all disc components. Make

Especially check to make sure end
washers and disc blades are on correct.
Foreign objects that become clamped
between disc components and fall out
through use.
Completely disassembly disc gang
components and clean thoroughly before
reassembling. Check spacers for uneven
edges that will not allow a tight seal
between disc blade and spacer.
Solid obstructions in the soil such as rocks
and stumps.
Remove solid obstructions, raise disc up
above solid objects or go around. Travel 3
mph or slower over small obstructions.
Bearing problems
Bent gang axle causing bearing to wobble.
Replace gang axle and damaged
bearings.
Foreign objects and/or dirt caught
between spacer and disc blades causing
bearing to wobble. Completely disassembly disc gang
components and clean thoroughly before
reassembling. Replace damaged bearings.
Abrasive material such as wire rubbing
against the bearing and destroying its
seals.
Remove abrasive material right away.
Replace damaged bearings.
Contaminated bearings caused by not
cleaning the grease zerks before adding
grease to the bearings. Always clean grease zerks before pumping
grease into the bearings. Replace
damaged bearings.
Pumping grease into the bearing too fast in
cold weather will pop off bearing seals.
Pump grease into the bearings slower
especially in cold weather. Replace all
damaged bearings.
