The Bush Disc Harrows are designed for garden preparation, game food plots, firebreaks or
orchard-vineyard use. Be sure to remove any sizable tree limbs, rocks, or debris from this
area. Do not attempt to disc wet or mucky soil and all areas should be well drained and
capable of being walked on without having the soil stick to your shoes.
Discing action will commence as soon as you lower the disc from transport position, the unit
touches the ground, and tractor horsepower, Never try to disc in reverse and when you
reach the end of a pass, raise the unit up into transport before turning. Trying to turn sharply
with the unit in the ground will cause extreme side loading on the discs and may cause
damage. Making disc gang adjustments is relatively easy by raising the disc off of the
ground, pulling the locking pin, making the required gang angle adjustment, and then
reverse the process till your back in action. It is extremely important that the disc harrow
operates level at all times. This will minimize the horsepower requirements and allow the
best flow of soil and residue through the machine.
Ground conditions and the finish you require will determine how you position the angles of your front and rear
disc gangs. Both of the front and rear disc gangs have the angle adjustment positions. The best ground finish
will usually be achieved when the rear gang is set at a slightly lesser angle than the front gang. The more
aggressive you set the angle of the gangs, the more aggressive the cutting action in the soil profile will be.The
more aggressive the cutting action is, the more horsepower will be required to pull you unit. Achieving the
desired effect may require a little experimentation in your given conditions. If the soil is building up on or
sticking to our discs then the soil is too wet and discing operations should be discontinued until the ground is
dry and more workable. Optional disc scrapers are recommended and will significantly improve overall
performance in conditions where soil continually tends to buildup or stick to discs.
