SCOPE AND PURPOSE
This guide is limited to Ibex TS51C drum mowers (also labeled with the original manufacturer
model name, Galfre FR/G 130). The guide covers models manufactured in 2020 and forward.
This manual is a guide to aid in the assembly only. Consult the Quick Start Guide and User
Manual for instructions on usage and safety.
UNCRATING
Heavier components can be lifted out of the crate, using lift straps or chains, if a lift is
available.
Figure 1 lifting the drum assembly
If no lift is available, the crate will need to be cut open for easier access. Remove the smaller
parts, then slide the drum unit out of the crate onto the ground. The drum mower bottom
skids drag across the ground during use, so it is alright to drag them to the location that you
plan to use for assembly.
Lay out the parts so you can see everything in one place.

Figure 2 parts ready to assemble.
Take the bag of parts and sort them out in like groupings. It makes finding the hardware much
easier during assembly.
Figure 3 hardware sorted out.
Grease the PTO drivelines before assembly. Also grease the plastic fittings on the free rotating
plastic guards. It’s much easier to do before assembly. Consult the driveline manuals that are
attached to the PTO drivelines for instructions on lubrication. Keep the driveline manuals for
future reference.

GUARD INSTALLATION
Install the plastic PTO guards as shown in the images that follow. They are easier to install
before assembling the mower.
The larger guard is installed on the gearbox facing the tractor.
Figure 4 larger guard installed on the gearbox facing the tractor
The smaller guard with a cutout is installed on the 3 point hitch gearbox on the other side,
with the cutout facing the rear. This cutout provides space to allow the PTO shaft to pivot to
90 degrees when the mower is switched to transport mode.
Figure 5 the smaller guard with the cut-out facing the rear (cutout may look different on your machine)
The other small guard without a cutout is installed at the drum unit PTO spline.

THREE POINT HITCH
The 2 lift pins must be secured to the 3 point hitch. Position the three point hitch so the two
arms face up. Find the two lift pins and the 2 smaller roll pins (spring pins) shown below. Oil
the holes in the pins and the hitch then oil the roll pin. Secure the roll pin with locking pliers
and drive through the holes with a hammer. The pins can be installed in a different
configuration than shown, for example if the width of your tractor’s lift arms is narrow, you
may want to install the pins facing inward.
Figure 7 install the pins in the arms as shown on both sides
Move the 3 point hitch assembly over to the back of your tractor. Attach to the tractor lift
arms and install the lynch pins.

Figure 8 attached to lift arms
Lift the 3 point hitch unit up and install the top link pin. Adjust the length of the top link to
make the 3 point hitch close to straight up and down.
Figure 9 level the 3 point hitch unit with the top link
BLADE INSTALLATION
The 6 cutting blades that come with the mower are installed and changed with the blade tool.
The blade tool is stored on the top of the spring arm that connects the 3 point hitch to the
drum unit, shown here fully assembled.

Figure 10 blade tool
Install the blades so that the angled edges are sloped downward. Position the blade tool so
that the two identical prongs are inserted between the two discs of the drum. Then raise the
arm so that the pin of the tool inserts into the slot on the upper disc. Pivot the tool up until
there is sufficient clearance, install the blade, and let the tool arm down.
The drum unit may need to be raised higher in order to have enough clearance to angle the
tool so that the two prongs fit below the upper disc. Once installed, be sure the blade is on the
pin and swings freely.
For safety purposes, never place your hand or fingers inside the opened space between the
discs.

ATTACHING THE DRUM UNIT TO THE 3 POINT HITCH
Place the drum unit so that it is oriented as shown in Figure 12. Be sure the PTO spline shafts
face each other.
Figure 12 move the drum unit over to the three point hitch assembly like this
You will use the swivel tee subassembly shown below to connect two lift arms to the three
point hitch assembly.
