3. PTO DRIVESHAFT SAFETY TIPS
Your flail mower is shipped with a PTO driveshaft.
Always ensure that the PTO shaft is no more than 15 degrees of horizontal when
operating.
-The following steps are recommended for safe operation of the driveshaft under field
conditions.
-Test hitch angle to prevent the driveshaft from:
�
Extending beyond the recommended maximum length.
�
Bottoming out
�
Reaching a position that allows joints to lock
�
Exceeding the maximum allowable angle for constant velocity (CV) joints.
-Specify and test telescoping members to allow the lowest possible thrust loads,
considering the expected working conditions.
-Specify and test torque limiters to control excessive shock.
-Where necessary, specify and test overrun clutches to prevent inertial loads from
overpowering the tractor.
-Provide a means to support the drive shaft when it is disconnected from the tractor, to
prevent damage during storage or transportation.
-Provided drive shaft is of shear design using a grade 5 bolt, if replacing this bolt do not
use higher grade as this may cause damage to the PTO driveshaft, Implement, or your
tractor.
-On drive shafts with torque-limiting or overrun devices, be sure to connect the device on
the end of the drive shaft nearest the chipper.
-Provide a proper clearance zone for the operation of the driveshaft, to avoid damage to
the shielding components.
-It is not recommended to use PTO adaptors which may defeat the purpose of the
tractor’s master shield and/or adversely affect the performance of the driveshaft.

4. PROTECTIVE GUARDS AND SHIELDS
Do not allow the flail mower to be operated without the side cover or fender deflector’s
properly in place.
PTO driveshaft should consist of a PTO master shield, integral driveshaft shield, and a
mower input connection shield.
1. Follow all flail mower and tractor instruction labels and manuals. The flail mower
should be used only with the tractor’s PTO master shield in place.
2. Specify and test an integral driveshaft shield with end cones which will overlap, but
not interfere with the PTO master shield or flail mower input connection shield.
3. A flail mower input connection shield should be used in addition to the integral
driveshaft shield, in order to guard the shaft coupling and any torque limiting device
installed on the driveshaft.
4. Check that all routine maintenance of the driveshaft can be done without removal of
the shields.
5. SAFETY INSTRUCTIONS
Do not attempt to operate the flail mower until you have read and understood this manual.
Always keep guards and flail mower shields properly installed while operating the flail
mower.
Keep the decals in place and verify they are understandable. New labels can be ordered
from Betst Power Equipment upon request. If your flail mower is repainted, be sure the
labels and decals remain visible.
Never leave the flail mower running unattended.
Do not attempt alterations, repairs or adjustments while blade rotor is turning. Always
disconnect the PTO and stop the tractor motor, then put keys in your pocket.
Only use tractor of specified HP for your model flail mower as defined in the
specifications.
Keep hands, feet and other extremities out of and away from the blade rotor
area. When checking blades, EXERCISE EXTREME CAUTION! If
accidentally rotated, the blade rotor can contain enough residual energy to
cause serious injury.
Never allow anyone to stand beside or behind mower while operating.
Keep everyone,
especially children and animals, away from the operation area.
Anyone who has not read and understood this manual should not be in the area.

6. OPERATOR PROTECTIVE GEAR
The following protective clothing and gear is recommended when using your flail mower.
EYES -- Wraparound Safety Glasses or Goggles
EARS -- Ear Plugs
HANDS -- Leather Gloves
FEET -- Steel-Toed Boots
LEGS -- Heavy Pants
ARMS -- Long-Sleeved Shirt
NO LOOSE CLOTHING SHOULD BE WORN AROUND THE FLAIL MOWER
7. OPERATION CHECKLIST
CAUTION : Look under flail mower before operating to be sure the blade area is clear.
Make sure that:
�
You have completed all steps of the assembly instructions
�
The PTO shaft doesn’t come apart or bottom out during the normal lifting range.
�
There in no person around mower.
�
Remove Tractor Drawbar
During and after operation, check the grass clippings or mulched limbs for size and
quality of cut. It may be necessary to adjust the cutting height. See adjusting cutting
height.
8. Flail Mower Connection and Operation
Remember that if flail mower blades are blunted they will not cut properly. Dirt, rocks,
nails, or other foreign material will shorten blade life.
Always review the manual before operating the flail mower.
Operate mower in a safe well known area with the rear pointed away from doorways,
sidewalks, or any areas where your view is obstructed or people may approach.
Only use 540 RPM PTO Selection, any other use will void the warranty and may cause
severe damage to the gear box or mower.
Farmer-Helper EFGCH Flail Mower 7 Revision 10-14-17
Connecting to Tractor
Make sure there are no obstructions under the flail mower
Align lower link arms of tractor to hitch clevises on mower, Insert lower hitch pins into
lower ball swivels and attach linch pins.
Attach tractor top link to upper floating hitch on mower with pin supplied. Secure with
lock pin.
Slide driveline end with shear system over the tractor’s splined PTO shaft and secure it
with locking device of driveline
Slide driveline end with twist system over the mower’s splined PTO shaft and secure it
with locking device of driveline.
Driveline should now be moved back and forth to ensure that it is secure on the PTO shaft
of the tractor and mower gearbox.
When raising the mower to the transport position, be sure that driveline does not contact
tractor or mower. Adjust and set the tractor’s 3-point hitch lift height so that the driveline
does not contact mower deck in the fully raised position.
When moving over paved or rock road way be sure mower is lifted off the surface.
To Begin Mowing
Clear the area to be mowed of objects and debris that might be picked up and thrown by
the mower blades.
Grass is best cut when dry. Mowing wet grass can cause plugging resulting in grass
clumps behind the mower.
Grass should be cut frequently as smaller clippings deteriorate faster.
If cutting extremely tall grass, it is best to raise the cutting height and mow the area, then
lower the cutting height and mow a second time at the desired height.
To begin cutting, observe all safety guidelines in the manual.
Always check Gear Oil Level before mowing
.
Farmer-Helper EFGCH Flail Mower 8 Revision 10-14-17
At low engine rpm’s you may experience jerking in the mower, increase the engine rpm until there
is no jerking.
Most cutting is preformed with the 3pt lift system in the float position.
If the blades are touching the surface while in float position, either adjust cutting height or raise
mower with 3pt lift into fixed height position. See cutting height adjustment.
At first begin mowing at a slow forward speed. Mower knives will cut better at a faster blades speed
and slower travel speed.
After mowing 50 feet, stop and check to see that the mower is adjusted properly for the cutting
conditions.
Do Not make sharp turns or attempt to back up while the mower is on the ground.
Do Not engage PTO with mower fully raised off the ground.
Normal mowing speed will be between 2-5 mph and you will need to maintain tractor PTO speed to
produce a clean cut so select a tractor gear and range that will maintain this combination. The
quality of cut or degree of debris pulverization will be better at lower ground speeds and cutting
denser ground cover or heavier brush may create the need to slow down. Remember to look back
often.
7. CUTTING HEIGHT ADJUSTMENT
The flail mower cutting height depends upon the height of roller, height of adjustable skids, and
length of top center link. See pictures at end of manual.
On uneven terrain the roller and skids should both be touching the surface of cutting area.
On even terrain the roller only needs to be touching the cutting surface.
On rough and rocky terrain it is recommend that you cut high with all parts of the mower 3” above
the ground. To achieve lowest cutting height in this type of terrain, raise roller and skids so mower
can be operated with 3 pt in fixed position, remember change in elevation may require you to adjust
cutting height to ensure blades do not make contact with the surface.
To adjust height of roller or skids, remove bolts and nuts that affix them, lift or lower both sides in
equal measurements, replace bolts and re-tighten. See picture at end of manual.
The top center link can also be used to adjust cutting height and aggressiveness of blades. In level
grass areas the top link should be adjust so the mower sits on a slightly lifted horizontal plane. In
dense or rough terrain the mower should sit in a slightly higher horizontal plane.
Farmer-Helper EFGCH Flail Mower 9 Revision 10-14-17
8. BLADE REPLACEMENT
The best way to tell if the blades need replacing is to watch the results of your mowing.
Dull blades cause many problems, including:
�
Loss of cutting power
�
Jamming or Plugging
�
Rough cutting with more vibration than usual
�
Rowing left in cut
To remove the blades, take the PTO shaft out of gear. Shut off the tractor and keep the
keys in your pocket.
The blades are accessed underneath the mower.
Prop up mower with suitable devise to hold the weight of the mower.
Inspect and remove/replace dull or missing blades.
9. BELT TENSION ADJUSTMENT
To adjust belt tension, take the PTO shaft out of gear. Shut off the tractor and keep the
keys in your pocket.
The belts are accessed behind black side cover.
Prop up mower with suitable devise to hold the weight of the mower.
Check the deflection of belts, should be between ¼ ”and ½ ”
To adjust tension, loosen bolts and nuts as shown in picture at end of manual.
Then using support move gearbox and shaft horizontally to adjust tension, then adjust
support bolt and lock nut to the adjusted height, see picture at end of manual.
Tighten all bolts and nuts that were loosed to adjust the tension.
10. LUBRICATION FREQUENCIES AND LOCATIONS
PTO SHAFT – 2 zerks on universal once a day with lithium based multipurpose grease.
ROTOR DRIVESHAFT – There is a zerk on each end of rotor shaft. Add multipurpose
grease before each use. (2-3 Pumps)
GEAR BOX – Check level each time before operating, drain/fill as needed.
HYDRAULIC OFFSET ROD – Apply lithium grease to sliding shafts.
