CHAPTER 2 SPECIFICATIONS
TRACTOR SPECIFICATIONS
CAUTION: Do not operate mower with a tractor that does not
comply with the following requirements:
Ⅰ.Horsepower-27(minimum)Ⅱ.Counter balance weight :It
may be necessary to add weight to the front end and/or left rear wheel of your
tractor to maintain adequate tractor stability and weight of your tractor and the
conditions in which you are operating your tractor. Front tractor wheels must
remain firmly on the ground at all times. Contact between front, wheels and
ground must be firm enough to provide good steering control.
CAUTION: Regardless of tractor weight and size, it in
always necessary to exercise reasonable care during tractor
operation to avoid tractor rollover and/or loss of steering
control.

CHAPTER 3 OPERATING INSTRUCTIONS
PREPARING YOUR MOWER FOR FIELD OPERATION
1. Check to be sure there are three blades on each drum. These blades
should be new or showing approximate equal wear.
2. A damaged or worn-out blade should be replaced immediately.
3. Damaged or worn out blade holders should be replaced immediately.
4. Be certain that PTO speed does not exceed 450rpm.
NOTE: It is very important that the machine be balanced. The high speed
of the drums (1720rpm) makes it imperative that the drums are equally
heavy on all sides so they are in balance. Both the drums and saucers
have been dynamically balanced at the factory and this balance should
6
not be disturbed when the mower is operating. Imbalance may cause
excessive vibration, which in turn may cause damage to the machine.
If you notice abnormal vibration in the machine or a change in the noise
that the machine produces, stop immediately and inspect the machine.
CAUTION: Disengage PTO, stop tractor engine, set park brake and wait
for blade rotation to stop before working on blades, drums or saucers.
5. Be sure all bolts and nuts are tight, especially the bolts securing the
gearbox lid.
6. Use original joints. For example, after a repair job, a new rubber joint
should be fitted between the gearbox and lid. This joint should be glued
in the lid its exactly the same location as the old one.
NOTE: The gearbox is subject to heavy strain when the mower is operating;
consequently, the lid is rigid and fitted with several bolts, these bolts must be
kept tight at all times. The joint that is glued to the interior of the lid should be
replaced carefully so that a metal contact is made between the lid and the box.
SAFETY BREAKAWAY
This machine is equipped with an automatic safety breakaway device. If the
drums meet an obstruction, the mower automatically swings back. Disengage
power take—off, when mower stops check the PTO for profile tube alignment.
To re—engage mower into mowing position, you simply back up the tractor,
while the mower is contacting the ground, until the mower swings back into
mowing position and the breakaway has reset. Do not operate the mower in
the tripped position.
Figure A
If for any reason, the breakaway device releases without the mower
encountering an obstruction, the adjusting nut #1, Figure A on the breakaway
should be tightened.
7. In case of wear to the bottom skirts of the drums above the blades, it is
possible to rotate the drum 40 degrees in relation to the blade holders by
7
removing the saucers and the blade holder. Figure B (40 degrees).
Figure B
8. Tighten Allen screws of saucers securely and recheck after a few working
hours.
9. The PTO drive shaft may have to be shortened to fit your particular tractor.
The shaft should be shortened a minimum amount only. A freewheeling
clutch must be fitted PTO shaft if the tractor does not have an internal
freewheeling clutch. Always use stabilizers or sway bars when attaching
the machine to the tractor to prevent side movement of the machine. To
put the mower into mowing position after transport, the transport tube is
placed in the upper position and the safety break away is fitted to the
upper pin of the hitch frame. Depending on the length of the top link, either
the front or the near holes in the hitch frames can be used. If the machine
leans too far forward when lifting in working position, use lower top link
pinhole.
8
10. Be sure protective curtains and shields are in place and in good condition.
Adjust the lower arms of the tractor 3-point in such a way that the mower
will be raised horizontally in mowing position.
CUTTING HEIGHT ADJUSTMENT
The cutting height may be adjusted slightly be means of the top link. Best
results are obtained by tilting the mower slightly backward in rocky conditions.
In order to prevent the re-cutting of the stubble, the mower should never be
tilted backwards beyond 5 degrees. In rocky conditions tilting backwards
extends blade life but not mowing quality.
INSTRUCTIONS FOR MOWING
1. Start the tractor and build up to correct drum speed (1720 rpm
--PTO 540rpm) before entering the crop.
2. Select the gear that allows your tractor to run easily. This will depend
on the crop the ground conditions.
3. Always use sharp blades since these will be more economical than
blunt ones.
4. The sub-frame has to be positioned horizontally; this enables the
machine to follow and ground contour correctly.
TENSION OF DRIVE BELTS
During the first few working hours, the drive belts may shows some stretch. A
spring attached to the belt tension device will maintain the correct tension of
the belts. Instructions for tightening the drive belts;
FIGURE C
1．Loosen lock nut 1, Figure C, of the tension belt .
2．Tighten the nut #2 ，until the spring tension indicator #3 ,just
9
touches the stop #4.
3．Relock the nut #1. Tensioning of the V belts is only necessary if belts are
slipping. Maximum tension in when the indicator is about 1/8” clearance
from the bottom.
If a V belt breaks or comes off, the whole set of belts should be replaced.
NOTE: If the V belts are over tensioned, damage will occur to the
gearbox input shaft bearings and main drive shaft bearings. If the V belts
slip, check the V belt tension. If this is correct and the belts still slip, you
should reduce the forward speed of the tractor.
CAUTION: Never tighten the nut so far that the compression spring
becomes in operative.
CHAPTER4 MAINTENANCE AND LUBRICATION INSTRUCTIONS
●=Grease
■=Oil every 5 hours of work
Figure G
The gearbox is filled with EP—0 mulligan grease. Refilling is only necessary
after repair; Grease level should come to the lower side of the horizontal shaft.

CHAPTER5 PARTS LIST
The DM135 mower is a two—drum mower. Each drum has three knives, which
can be changed quickly with a simple tool. The hay cut by the knives is carried
between the drums and put in a loosely laid swath. Three V—belts transmit
power to the input gear shaft, then to the main drive shaft, which in turn drives
the drums through the bevel gears.
A breakaway device is incorporated on this machine, which automatically
operates when the mower hits an obstruction. This protects the drums from
damage.
A complete part list section is also contained in the manual for easy reference
to parts. The use of this section will provide a fast, accurate way to order parts.
We recommend that this manual be readily available for reference at all times.
Manufacturing Company reserves the right to make changes in engineering,
design, and specifications; add improvements, or discontinue manufacture at
any time without notice or obligation.
