Operational advice
Insufficient Depth Obtained
(a)
adjust depth control equipement
(b)
insufficient power : use lower tractor gear
(c)
chaincase on hard soil. Further passes required
(d)
blades “trowelling” (rolling over ground), use lower tractor gear
(e)
blades incorrectly mounted
Tilth too fine
(a)
use a faster tractor gear
(b)
raise levelling board
Tilth too coarse
(a)
use lower tractor gear
(b)
wait until soil is drier if sticks
(c)
lower the levelling board
Blades “Ballinq up” with soil
(a)
ground too sticky for working
(b)
raise levelling board
(c)
decrease tractor speed
Excessive Blade Wear
(a)
reduce rotor speed
(b)
replace loose or bent blades
Machine “Bumping” on Ground
(a)
obstacles entangled in blades
(b)
blades incorrectly mounted with no scroll effect or blades fitted with blunt edge leading or broken
blades
Obvious Points
(a)
Machine not level - cutting too deep on right side. Shorten right hand tractor lift rod or adjust
depth control wheel (b) Not overlapping - drive closer to last run
(c)
Working on hillsides. Work up the slope if possible. If lateral work cannot be avoided, work from
the top to the bottom in order to limit any terracing effect.
Advice
1.
When operating the machine the most suitable practice is to work in “lands”
2.
The worked ground should always be to the right of the driver.
3.
Working on the field headlands should not be carried out until the “lands” have been completed.
4.
Always raise the machine before turning.
THE MACHINE SHOULD NEVER BE
LOWERED WHILST THE TRACTOR IS TURNING.
