Page 42 INTRODUCTION We are pleased to have you as an Schulte customer. Your Rotary Cutter has been carefully designed with care and built with quality materials by skilled workers to give maximum service with minimum down time. This manual is provided to give you the necessary operating and maintenance instructions for keeping your rotary cutter in top operating condition.
Page 43: Equipment Specifications
INTRODUCTION The GX-150 general duty rotary Cutter is designed primarily for weeds, grass, and brush to 4” diameter. The side skirts are 13-5/8” deep. This additional room under the deck, along with high blade tip speeds allows for a better cut and better material flow. The one piece center shield allows for easy and full access to drivelines, clutches and gearboxes on the center section.
Page 44: Key Operation Points
ALWAYS OPERATE WITH THE WING HYDRAULIC CYLINDER CONTROL VALVES IN A FLOAT POSITION. • For maximum performance and service life, Always use Genuine Schulte replacement parts. Operating Noise Level/Sound Pressure The sound levels at the operator's ear from the attached machine (rotary cutter) are at least 10 dB(A) below the levels from typical Agricultural tractors used to power and transport this machine.
Page 45 GENERAL STATEMENT AFFECTING ALL SCHULTE WARRANTY Schulte Industries Ltd. warrants to the original purchaser only, that in the event of any defect in material or workmanship in the product sold by Schulte Industries, the subject of this warranty (“the goods”) during the warranty period mentioned below the manufacturer will provide the coverage specified below.
Page 46 • The Dealer must keep the failed part until the claim is processed, to allow Schulte Industries the option of further examination of the part. Further examination may mean that pictures are sent, or that the part be returned to Schulte.
Page 48: General Assembly
Chain Guards The GX-150 comes standard with single or double chain guards. Use the Parts Manual for chain guard locations on the rotary cutter. If your machine is equipped with single safety chains insert the first link of the 5 link chain into the first slot of the chain rail.
Page 49: Hydraulic Circuits
Refer to the Parts Manual for a complete list of fittings and hydraulic hose part numbers. NEVER FORCE THE WING LIFT LOCK PINS OUT OF THEIR LOCK POSITION AS THE WINGS MAY SUDDENLY DROP CAUSING INJURY OR EVEN DEATH GX-150 03/21 Assembly Section 3-3 © 2021 Alamo Group Inc.

The shields must be regularly greased and checked that they rotate freely on the driveline. Refer to the Lubrication section for greasing intervals. GX-150 03/21 Assembly Section 3-4 © 2021 Alamo Group Inc.
Page 51: Pro Level
If the rotary cutter obscures the tractor warning or tail lights, the rotary cutter MUST be equipped with a transport light kit. Check local highway regulations concerning moving machinery on highways. GX-150 03/21 Assembly Section 3-5 © 2021 Alamo Group Inc.
Page 52: Installation Of Lights
Test the circuit. The lights should operate in unison with your tractor lights. If the turning lamps are opposite to the tractor, reverse the output to extension harness connections. If the lights do not work at all, check all connections are snug. GX-150 03/21 Assembly Section 3-6 © 2021 Alamo Group Inc.
Page 53: Assembly From Truck Shipment
ASSEMBLY Assembly from Truck Shipment The following are instructions to set up a GX-150 cutter that has been delivered on a truck. When the cutter is received the hitch will be flipped back onto the cutter as shown on Figure AsmP-R- 0465.
Page 54: Shipping Strap
A shipping strap was installed on the unit prior to leaving the factory (shown circled to the right). The shipping strap must be removed before the cutter can be used.
