Page 48: General Information
ASSEMBLY GENERAL INFORMATION The FX-520 Mower can only be used with tractors that have 1000 RPM PTO. Check oil level in all gearboxes before operation. Refer to the Lubrication section of this manual for recommended oil type and viscosity. Lubricate all grease fittings. Refer to the grease schedule in this manual.
Page 49: Phasing System
The result of this stepping down of cylinder diameters is that all cylinders move at the same rate resulting in a ‘level lift’. The phasing system hoses are marked in yellow at the tractor connection. FX-520 06/16 Assembly Section 3-3 © 2016 Alamo Group Inc.
Page 50: Rephasing Groove
During normal operation small amounts of oil may leak past piston seals causing cylinders to fall out of synchronization. Synchronization can be restored by fully extending cylinders and holding the circuit open for period of time. FX-520 06/16 Assembly Section 3-4 © 2016 Alamo Group Inc.

NEVER USE YOUR HANDS TO STEADY THE HITCH BLOCK WHILE THE TRACTOR IS BEING BACKED INTO THE HITCH. NEVER STAND BETWEEN THE TRACTOR AND THE ROTARY CUTTER WHILE THE TRACTOR IS BEING BACKED INTO THE HITCH. FX-520 06/16 Assembly Section 3-5 © 2016 Alamo Group Inc.
Page 52: Wheel Standards
Tire Spacing For Row Crop The FX-520 has adjustable wheel standards so it can accommodate a variety of row spacing. Before adjusting any wheel arms ensure the cutter is safely blocked up so that the weight is off the wheel arm you intend to adjust.
