JD 7X30 COUGAR Operation Section 3-7
OPERATION
MOWER OPERATION
When rotating parts are in motion, serious injury may occur if caution is
not used or danger is not recognized. Never allow bystanders within
300
feet of the machine when in operation. Extreme care should be taken
when operating near loose objects – such as gravel, rocks and debris.
These conditions should be avoided.
The rotating parts in this machine have been designed and tested for rugged use.
However, they could fail upon impact with heavy solid objects – such as steel guard
rails, concrete abutments, etc., causing them to be thrown at a very high velocity. Never
allow cutter head to contact such objects. Inspecting the cutting area for such objects
and removing them prior to mowing can help eliminate these potential hazards.
Once on location, lower the mower deck slightly above the material to be cut, so
the mower does not have to start under a load. With the tractor at an idle, engage
mower. Bring tractor R.P.M. up to 1900 – 2200 R.P.M. and
slowly lower deck to ground
level.
A flail mower deck should be carried so that part of the deck weight is carried by the
boom and part carried by the ground roller, when mowing on the ground. When the flail
mower is carried this way, the ground roller follows the contour of the ground more
easily during mowing operations.
The rotary mower deck should always be carried rather than dragged on the skid
shoes when mowing on the ground. Dragging the rotary mower deck increases the
side loads on the boom, decreases the horsepower available to the cutter head, and
reduces the ability of the accumulator the carry part of the weight of the boom during
mowing operations.
During mower operation, the hand throttle must be used to maintain engine speed
at1900 – 2200 R.P.M. This prevents radical changes in mower spindle speeds, reducing
the possibility of cutter assembly damage.
The horizontal positioning action of the boom is designed to position the cutting
head and provide a limited pressure relief when excessive pressure is applied to the
boom. Do not force the cutting head into heavy branches or stumps. Damage to the
unit may result.
When using the rotary cutting head for trimming trees and shrubs, let the
mower saw into them. Do not lower the mower head down directly onto a
tree or stump. The mower blades are designed to cut with the end, and
misuse can cause damage to the blade and a hazardous situation for the
operator.
Powering the boom down, forcing mower deck onto ground may damage
mower deck and it’s attachment to the boom, creating a potentially
hazardous situation.
