Tips for Best Performance
Locking the Wheel Differential
In rough or wet terrain, or on moderate
slopes, you can lock the wheel differential,
so both wheels turn together with improved
traction.
To lock the wheel differential, move the
lever between the lower handlebars to the
right (Figure 4).
Note: When mowing with the wheel
differential locked you may find it more
difficult to turn and maneuver.
Slopes
· We do not recommend using the DR
FIELD and BRUSH MOWER continuously on slopes greater than 25 degrees. Doing so could
deprive the engine of oil and cause it to overheat.
®
Figure 4
· When moving across moderate slopes, in
ditches, etc., locking the differential will
improve traction (Figure 6).
· Note that the mowing deck pivots from side
to side (12 degrees in either direction),
which helps avoid scalping, and keeps the
weight balanced over the drive wheels when
operating on uneven terrain (Figure 5).
· Please read the safety information beginning
on page 1.
Figure 5Figure 6
DR® FIELD and BRUSH MOWER Safety & Operating Instructions9
If the machine gets hung up...
· Disengage the blade. Do not try to free
the machine from stumps or debris while
the blade is engaged.
· Try putting the machine in reverse and
backing away from the obstacle.
· Try pushing down on the handlebars to lift
the mowing deck over the obstacle
(Figure 7).
· If you need to leave the operating position,
first put the machine in "N" (neutral), turn
the engine off and disconnect the spark
plug wire.
Caution: DO NOT touch the exhaust
areas when reaching for the spark plug—they are very hot.
Cutting Brush & Saplings
· When cutting woody material, small
saplings, etc., allow the machine to ride
up and over material slowly. Adjust
your forward speed to varying conditions
(Figure 8).
Figure 7
· After cutting brush, etc., you may want
to mow over it again to remove any
remaining branches. It works best to
mow from the trunk end toward the top
as brush lies on the ground.
Reverse
Figure 8
· Be very careful of your footing when
operating the machine in reverse. Know
what's behind you and take your time.
· The blade will engage in reverse, however, we don't recommend continuous mowing in reverse.
Mow in the forward gears, using reverse for maneuvering.
· If you find it difficult to shift into reverse, lightly "feather" the clutch lever as you pull the shift
lever into reverse, then quickly release the clutch lever.
Cutting in Wet & Heavy Growth
· Be very careful of your footing when mowing in wet conditions. Avoid steep slopes and other
slippery areas.
· Use a lower, slower speed.

General Maintenance
For Engine Maintenance, Please Refer to the Engine
Manufacturer's Owner's Manual.
IMPORTANT: Because of the demanding conditions the DR® ALL-TERRAIN™ FIELD
and BRUSH MOWER is used in, air filters and oil should be changed more frequently
than is recommended in your Engine Manufacturer's Owner's Manual. Please follow
these recommendations:
Paper Air Filter:Should be replaced every 25 hours of operation.
Oil: Should be drained and replaced every 25 hours of operation.
Regular maintenance ensures the best performance from your machine. Follow these
instructions as well as the recommendations in the Engine Manufacturer's Owner's Manual
to keep your DR® FIELD and BRUSH MOWER in top condition. Use the daily checklist on
the back cover of this manual whenever you operate your mower.
!
WARNING: Some of the following procedures require access to the underside of the
machine. Before you tip the machine on its side with the discharge chute facing up, you must
drain the oil and gas, and remove the air filters.
Lubrication
Your DR® FIELD & BRUSH MOWER is greased at the factory. You do not need to lubricate it for
the first 25 hours of use.
Tools Needed:
· flexible hose grease gun
· Lithium grease
· FLUID FILM
!
WARNING: Always remove the spark
plug wire before servicing your machine.
®
or WD-40® lubricant
Grease Fittings
1. There are three grease fittings below the
black belt guard that need maintenance:
· The mower pivot tube (Figure 9)
should have 1-2 pumps of grease every
25 operating hours.
· The belt idler arm (Figure 9) should
have 1-2 pumps of grease every 25
operating hours.
Figure 9
DR® FIELD and BRUSH MOWER Safety & Operating Instructions11
· The mower spindle (Figure 10) should
have 3-4 pumps every 100 operating
hours.
Note: Over greasing will cause grease
to leak out of the seals onto the mower
drive belt. Unless instructed otherwise,
pump only until you feel slight
resistance (1-2 pumps).
Figure 10
2. The following areas should be lubricated with FLUID FILM® or comparable lubricant every 10 to
20 operating hours—more often if the machine is operated in extremely dusty conditions:
· The differential fork at both ends (Figure 11).
· The axle above the hub where the spring is (Figure 11).
· The drive chainand the chain adjuster slide plate (Figure 12).

Battery
Electric-Starting Models
Proper care can lengthen the life of a battery. Follow these recommendations to ensure your
battery's best performance and long life:
· Do not allow the battery charge to get too low. If the machine is not used, the battery should be
charged every 4 – 6 weeks.
· Store an unused battery in a dry area that does not freeze.
· Do not charge an already charged battery. In theory, our battery can not be overcharged with a
trickle charger; however, when a battery is fully charged and the charger is still on, it generates
heat that could be harmful to the battery. A fully charged battery will read 12V-13.2V with a
voltmeter.
· Do not continue to crank your engine with a low battery.
Charging the Battery
If the battery loses its charge, you'll need to use a trickle charger (like the DR® Battery Charger) to
recharge it. The charger should have an output of 12 volts at no more than 6-8 amps.
· At 1 amp the battery may need to be charged for as much as 48 hours.
· At 2 amps the battery may need to be charged for as much as 24 hours.
· At 6-8 amps the battery will be charged in 2 to 3 hours.
Caution: At 6-8 amps a battery can overcharge.
Note: Using the recoil starter (ATM10E Briggs & Stratton model only) and then running the engine
will not recharge a dead battery.

· Change the oil.
· Remove the spark plug and pour about 1 ounce of motor oil into the cylinder hole. Replace the
plug and pull the recoil starter rope until you feel strong resistance. This will coat the piston and
seat the valves to prevent moisture buildup.
· Clean/replace the air filters.
· Clean dirt and debris from the cylinder head cooling fins, blower housing, debris screen and
muffler area of the engine.
· If your engine has a fuel filter, replace it.
· If your DR
using a gas stabilizer. This will prevent the carburetor from gumming up. If there is dirt or
moisture in the gas, remove it by draining the tank. Completely fill the tank with fresh, unleaded
gas and add the appropriate amount of stabilizer or gasoline additive. Run the engine for a short
time to allow the additive to circulate. Close the gas shut-off valve to prevent carburetor
overflow and leakage.
