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.
Take the bag of parts and sort them out in like groupings. It makes finding the hardware much
easier during assembly. Refer to Figure 2 and the subsequent list for hardware identification.
Note: Occasionally the manufacturer will pre-install some components and this may result in
your hardware assortment being slightly different than what is shown.

PTO GUARD INSTALLATION
Install the plastic PTO guards. They are easier to install before assembling the mower. Use the
set of 4 screws and washers provided in the hardware bag to install the larger guard on the
gearbox facing the tractor as shown in Figure 3. Note that this guard may appear somewhat
different, and may already be installed on the gearbox.

2022-1.1 IBEX EQUIPMENT CO. 2
Figure 3 larger guard installed on the gearbox facing the tractor
The small guard with a cutout is installed on the 90 degree 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. This guard is normally already installed.
Figure 4 smaller guard with cut-out facing the rear (cutout may look different than picture)
Get the small guard without a cutout and use the set of 3 small screws and washers to install it
at the drum unit PTO connection as shown in Figure 5.

THREE POINT HITCH
Find the two 3 point hitch pins (Figure 2, B) and the 2 smaller roll pins (Figure 2, O). The hitch
pins can be installed facing outward or inward to accommodate different lift arm widths, so
you may want to bring the hitch close to your tractor to see how it lines up before you decide
which position to install the pins.
Position the 3 point hitch so the two arms face up. Oil the holes in the pins and in the hitch,
and then oil the roll pin. Secure the roll pin with locking pliers and drive it through the holes
with a hammer.
Figure 6 install the pins in the arms as shown

Attach the 3 point hitch to your tractor’s lift arms. You will need linchpins to secure them (not
included).
Figure 7 3 point hitch attached to tractor’s lift arms
Lift the 3 point hitch unit up and install the top link pin (Figure 2, A). Adjust the length of the
top link so that the 3 point hitch is plumb (straight up and down).
Figure 8 plumb the 3 point hitch unit using the top link
BLADE INSTALLATION
The six cutting blades that come with the mower are installed and changed with the blade
change tool. The blade change tool is stored on the top of the spring arm that connects the 3
point hitch to the drum unit, shown in Figure 9 fully assembled for identification.

2022-1.1 IBEX EQUIPMENT CO. 5
Figure 9 blade tool
To install a blade, position the blade change tool so that the two identical prongs are inserted
between the two discs of the drum, as seen in Figure 10. 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. Be sure to install the blade so that its angled
edges are sloped downward. Once installed, be sure the blade is on the pin and swings freely.
Note that the drum unit may need to be raised to provide enough clearance to properly angle
the tool.
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 11. Be sure the PTO spline shafts
face each other.
Figure 11 drum unit positioned in relation to the 3-point hitch frame
To connect the 3 point hitch frame to the drum unit, first get the larger lift arm with a swivel
tee attached to it, shown in Figure 12. Remove the cap of the tee and place it on top of the
drum unit with the tee facing the 3 point hitch. Slide the tee into the 3 point hitch frame and
install the cap as shown in Figure 13, threading the nut only until you feel some resistance. The
nut will be removed later when mounting the top arm. Wait to attach the other end of the
lower arm until after the next step.
