Lights and a SMV emblem must be equipped directly on implements if the visibility of the tractor warning signals are obscured. Maintain all manufacturer equipped safety shields and guards. Always replace shields and guards that were removed for access to connect, service, or repair the tractor or implement. Never operate the tractor PTO with the PTO master shield missing or in the raised position. OPS-U- 0004 OPERATION ©2008 Alamo Group Inc. OPERATION A60/A72 01/08 Operation Section 4-6 4. Tractor Horsepower The horsepower required to operate the mower depends on several operating factors including the vegetation to be cut, terrain condition, operator experience, condition of the mower and tractor, and others. For most mowing conditions, the A60 mower requires a tractor with a minimum of 30 HP and the A72 mower requires a tractor with a minimum of 40 HP. Operating the mower with a tractor that does not have adequate power may damage the tractor engine. Exceeding 75 HP may cause mower damage by overpowering the unit in heavy cutting conditions. 4.1 3-Point Hitch The tractor 3-point hitch must be rated to lift at least 850 lbs. if attaching an A60 and 1050 lbs. if attaching an A72 mower.. A60/72 mowers can attach to tractor’s with either a CAT I or II hitch. Refer to the tractor operator’s manual for the category of the tractor used. If the hitch does not conform to ASAE Cat I or II dimensions, the mower may not fit or raise properly. Consult an authorized dealer for possible modification procedures to mount nonconforming hitches. Use the correct hitch pins for the hitch category being used. For a Cat I hitch, 7/8” lower and 3/4” upper diameter hitch pins are used and Cat II hitches require 1-1/8” lower and 1” upper diameter hitch pins.

Front end weight is critical to maintain steering control and to prevent the tractor from rearing up while driving. If the front end is too light, add weight until a minimum of 20% total weight is reached on the front tires. Front weights and weight carriers can be purchased through an authorized tractor dealership. OPS-U- 0005 OPERATION ©2008 Alamo Group Inc. OPERATION A60/A72 01/08 Operation Section 4-7 4.3 Power Take Off (PTO) Depending on the unit, the mower is designed to operate at a PTO speed of 540 or 1000 RPM. Most tractors operate at either 540, or a combination of 540 and 1000 RPM PTO speeds. The operating speed of the mower and tractor can be determined by the number of splines on the driveline yoke and PTO output shaft. Those operating at 540 RPM will have a 6-spline shaft and those operating at 1000 RPM will have a 21-spline shaft or a 1-3/4” 20 spline shaft. Refer to the tractor owner’s manual for instructions to change PTO speeds on models that operate at more than one speed. If operating an older model tractor where the tractor’s transmission and PTO utilize one master clutch, an over-running clutch must be used between the PTO output shaft and the driveline of the mower. An authorized tractor dealer can provide the over-running clutch and its installation if needed. OPS-U- 0006 DO NOT use a PTO adapter to attach a non-matching Implement driveline to a Tractor PTO. Use of an adapter can double the operating speed of the Implement resulting in excessive vibration, thrown objects, and blade and implement failure. Adapter use will also change the working length of the driveline exposing unshielded driveline areas. Serious bodily injury and/or equipment failure can result from using a PTO adapter. Consult an authorized dealer for assistance if the Implement driveline does not match the Tractor PTO. (S3PT-14) Never operate the Tractor and Mower if the Implement input driveline is directly connected to the Tractor transmission. Tractor braking distances can be substantially increased by the momentum of the rotating Mower blades driving the Tractor transmission even though the Tractor clutch has been disengaged. Install an over running clutch between the Tractor PTO and the Mower driveline to prevent this potentially dangerous situation. (S3PT-16) 5.
