BASIC OPERATION
BASIC OPERATION 8
1. Before beginning your job, walk the mowing area and clear all hidden hazards such
as large rocks, stumps, utility lines and hidden debris like broken glass, bottles and
miscellaneous materials. Projected debris can cause injuries to operators, pedes-
trians, livestock and property.
2. While inspecting your work area for debris, be on the lookout for bees, fire ants,
poison ivy and poison oak. Taking note of potential area hazards will increase your
productivity as well as your safety. Also avoid improper working conditions such as
overly saturated grounds, which can cause slippery conditions.
3. Check your discharge path. Most mowers and brush cutters will have some combi-
nation of material discharge system. Mulching flail mowers and brush cutters are
bi-directional. This allows the utilization of both sides of the blades. Always make
sure you know the discharge direction and discharge flaps are properly secured
and in good working order. Never start the mower if attachments are not securely
fastened to the power unit.
4. Your brush cutter is most efficient when the knives are sharp and turning at full
RPM. 1500-1800 RPM is the recommended speed the cutter shaft should turn.
5. Loading or “lugging down” the cutter excessively will reduce its cutting capacity and
result in increased hydraulic oil temperature. Stay aware of the cutter drum speed
and lift out of the cut until maximum speed is regained before resuming.
6. When cutting larger diameter material, lay the tree down with the blade and plane
the tree from side-to-side. This will result in a finer mulch which is quicker and eas-
ier on the machine than trying to grind a tree of 3” or more diameter from the top
down.
7. Never allow bystanders to within 150 feet of mowing or brush cutting.
8. Do not use this mower as a bucket to dig up roots and spread out piles of dirt.
Damaged caused by such activities will result in expensive repairs which will not be
covered under warranty. This weldment design is strong enough to last for decades
if cared for properly.
9. Frequent and routine maintenance procedures should be followed to insure the
safe and efficient operation of your brush mower
10. Abuse is indicated by drum damage, where the sides of the knives have left inden-
tations on the drum. Abuse is also indicated by premature knife failure across the
whole drum. If cutter abuse is not prevented, ear failure will follow. To prevent
abuse, always reduce cutting load before significant cutter drum speed is lost.
