Scope and Purpose
This guide is limited to Ibex TS51C drum mowers (also labeled as Galfre FR/G 130). The guide covers models
manufactured in 2020 and forward.
This manual is a guide to aid in the assembly and start-up basics only. Consult the operations 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 bag of hardware.
Figure 4 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
The plastic guards for the drivelines are easier to install before assembling the mower.
Figure 5 the large guard installs on the gearbox facing the tractor
Figure 6 the guard with the notched out area is installed on the drum unit as shown (cutout may look different on your machine)
Figure 7 the third guard is installed on the remaining location on the 90 degree gearbox

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 8 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 9 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 10 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 11 blade tool
Find the 6 blades and separate them. Install them with the beveled edges face up. Using the blade tool, pry open
the drums and install the blade by fitting the hole of the blade over the pin inside. For safety purposes, never
place your hand or fingers inside the opened space between the discs. Position the tool, raise the arm, install the
blade, and let the tool arm down. Be sure the blade is on the pin and swings freely.

Attaching the Drum Unit to the Three Point Hitch
Place the drum unit so that it is oriented as shown in Figure 13. Be sure the PTO spline shafts face each other.
Figure 13 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.
Figure 14 swivel tee assembly
Figure 15 the cap and hardware are shown here for the swivel tee
Put the swivel tee through the hole, without the cap, so that the cap goes on top. Install the nut & bolt only until
you feel some resistance – don’t tighten all the way as the bolt will need to come back out to mount the top arm
later. You will need either an adjustable wrench or a 30mm socket to secure the nut.

Next get the shorter of the two swivel pins as seen in Figure 17. It usually has the washer and nut attached.
Figure 17 short swivel pin
Align the two holes on the support arm so that they centered to the bushing. The pin will not go through and the
plastic bushings could be damaged if the holes are not well aligned first. You can use an adjustable height stand
such as a chair to hold up the arm while aligning the holes. Take note of the orientation of features so that it is
installed right side up.
