Failures of the mower push-pull switch:  
Alamo has recently received reports of failures of the referenced switch. The failures  
modes are:  
(a)  
(b)  
Knob pulls off rod.  
Rod and Knob pulls out of switch body.  
Test performed on numerous switches indicates that the (b) failures are due to excessive  
force being applied to the knob when shutting off the mower. Specifically, the knobs are usually  
roughly slapped to turn the mower off. After internal parts of the switch are damaged, the rod can  
then be pulled out easily. The (a) failures are due to the knobs not being securely tightened.  
To prevent these failures from occurring, or to replace a damaged switch, use the following  
procedure to adjust the travel of the switch. (See attached diagram).  
1.  
2.  
Install the switch body in the holder and tighten the nut.  
Screw the Knob on the rod to the bottom of the thread, but do not overtighten. It  
will probably be necessary to hold the rod with pliers to get the knob tight, if you do  
use caution not to score the rod with the pliers.  
3.  
Measure the distance (if any) between the knob and the nut. Record the  
measurement.  
4.  
5.  
If a Gap exists between the knob and the nut, remove the knob.  
Remove the nut and install the same thickness of flat washers that was  
measured in step 3. Install and tighten the nut> DO NOT install more washers  
thanneededtotakeupthespace.FlatWasherPartNo.00023500orequivalentcan  
be used.  
6.  
Install the Knob, using Locktite or similar thread locking compound. Thread the  
knob on the rod all the way. Test to make sure that when the switch is "Off" (with  
rod pushed in) that the knob can not travel further into the switch.

New Seal Protector Added to Blade Bar Assembly:  
Afewmachineshaveexperiencedoperationalproblemssuchasfailureofthebladebartorotate  
when the mower is engaged or a slight loss of power at the blades. Sometimes it is assumed that the  
spindle has seized and the spindle is replaced without investigating further.  
The problem is usually found to be that the spindle end cap cover is binding on the spindle  
housing, creating sufficient drag on the shaft to result in the symptoms described above. This condition  
is a result of material (Vines, Wire, etc.) wrapping around the cover and forcing it to contact and drag  
against the spindle housing, causing no damage to internal components of the spindle.  
Anewsealprotector hasbeendesignedtoaidinpreventingmaterialfromwrappingaroundthe  
seal cover area. While nothing can completely prevent material from getting to the seal cover, the new  
seal protector should greatly reduce the probability of spindle seizures due to these causes.  
Ifamachineisoperatingorisgoingtooperateinanapplicationinwhichmaterialislikelytowrap  
around spindle, the following parts can be ordered and installed. The old seal protector (# 02968868)  
which is on the spindle will be removed and discarded. The Old Part No. 02968868 will be ordered but  
the new Seal Protector Part No. 02970459 will be shipped with installation instructions. If only the new

Oil Leaking from new single Acting Hydraulic Cylinders:  
There have been numerous cases of the dealers and customers replacing single acting  
hydraulic cylinders on new machines due to oil leakage out of the vent plug in the cylinder.  
In many of these instances, no defect could be found in the cylinders. Further investigation  
has revealed that he manufacture of our cylinders is leaving oil in the cylinders after their testing. The  
Oil is left to help protect the interior of the cylinders during storage. When the cylinders are fully  
actuated, they are forcing this oil out the vent plug, causing what appears to be a leaking cylinder  
throughtheventplug.Eventheoiliscleanedoffthecylinderaftertestingthereisenoughoilstillinside  
the cylinder to bleed out when used.  
If you have a New Cylinder that appears to be leaking from the vent plug, The oil should be  
cleaned off and unit ran for a few days to a week to determine if the Cylinder is leaking, or if it is the  
oil that was left in the cylinder to protect it. It has been found that in some cases it has taken as much  
as a week for this to appear that it is not leaking.  
Ifafterrunningandcyclingthecylinderduringoperationandthecylindercontinuestoleakthen  
the necessary repair should be performed.

Dead Batteries on New tractors:  
There have been several reports recently of dealers receiving machines with dead batteries,  
some of which could not be satisfactorily recharged. Please see the attached copy of a tag which  
is coming with the new tractors.  
The "small electrical discharge" being mentioned amounts to a constant drain on the battery.  
Ifthebattery cable(+Post)isleftconnectedforalongenoughtimewiththetractorinactive,thebattery  
will become sulfated (permanently damaged) and will not accept a charge. Sulfated batteries are not  
warranted through the battery manufacturer.  
At present, the only alternative to removing the battery cable would to be install a battery  
disconnect switch in the negative cable, which would allow the battery to be easily isolated. These  
switches are available at most major tractor dealers. USE CAUTION when installing any thing on  
battery cables, disconnect the positive cable before installing disconnect switch and make sure after  
switch is installed that it is "OFF" before reconnecting Positive Cable.  
_
ATTENTION ! BATTERY CARE  
+
Your new Tractor has electronics which cause a very small electrical demand on the battery. If the  
tractor in not in use for an extended period, disconnect battery to avoid damage by excessive discharge.

Interference between Tube Clamps and Main Frame:  
It is possible that the boom hydraulic tube clamps may contact the main frame when boom  
is raised to its highest position. This condition effects only machines with certain frames. If you have  
a machine that has this interference problem use the procedures described in this bulletin to correct  
the problem. (See Figure 1).

Tilt Link Arm Stop:  
Some Machete models may exhibit interference between the head tilt cylinder and the cutter  
motor support plate. This can result in a bent head tilt cylinder rod, a damaged cylinder gland cap, or  
a damaged cutter motor housing.  
In order to avoid possible damage, a stop should be fabricated and installed which will limit the  
head tilt retraction before interference occurs.  
A stop made from 1/2" X 2-1/4" HRFB X 6-1/2" long should be welded to head tilt link arm  
weldment as shown in figure 1. This will require welding and painting.  
To locate the proper angle position of the new stop, carefully retract the head until the cutter  
motorsupportplateandtheheadtiltcylinderhasaclearanceof1".Usecaution,donotdamagecylinder  
when retracting the head. Place the new stop plate in the head tilt link weldment and lay it flat on the  
dipper arm. Mark this position, and weld the stop in place as shown in Figure 1. It is important that the  
stop is installed so that it flatly contacts the dipper when retracted in order to avoid point loading on the  
boom. Extend and retract the cylinder to ensure proper installation.

New Thick Blade Bar & Larger Bolts:  
Early October1996,inordertoensureanextendedservicelife,anewbladebarwasintroduced  
which featured larger blade bar leaf bolts (from 7/8" to 1-1/4") and a thicker bottom leaf. As a result,  
longer mounting bolts (from 3-1/2" to 4") are required to ensure adequate thread engagement into the  
spindle shaft.  
When ordering a replacement blade bar using the original number, the new blade bar design  
will automatically be sent. However, the 4 longer mounting bolts may not be included.  
Therefore, when ordering a replacement blade bar, ensure that the proper length mounting  
bolts(P/N02964861whichisa4"Bolt)arealsoreplaced.DONOTattempttomountthenewstyleblade  
bar using the old shorter bolts. The best way is to always check the replacement bottom leaf thickness  
as compared to the bottom leaf that was removed. If the replacement is thicker then the new longer  
bolts will be needed. Another way to determine which one you have check the Leaf retaining bolt size.

Lock Valve Installation Instructions:  
Instructions for installing a lock valve on the tilt function of an Alamo Industrial Model Machete  
Boom product manufactured before May 1, 1997.  
Thenominalleakdownrateforthecutterheadtiltsectionoftheelectricallycontrolledpositioning  
valve is one inch of rod travel in four minutes. If your machine exhibits a leak down rate substantially  
greater than this, it typically indicates excessive valve component wear due to contaminated oil in the  
tractor. Refer to the Tractor's Operator / Maintenance guide concerning Oil & Filter change intervals to  
eliminate contamination possibilities.  
If the cutter head tilt cylinder leak down is greater than one inch of rod travel in four minutes and  
this is considered excessive, a lock valve may be added to the tilt function of the boom machine. Alamo  
Industrial has developed a cure for this and can provide (at a nominal charge) all the parts for a lock out  
vale for the tilt function. The Lock valve will only work on the tilt function of the Boom Machine due to the  
designofthehydraulicSystem.Theonlypartsthatmustbeprovidedbytheinstalleraretwo,twelveinch

Procedures to eliminate erratic boom operation caused by microwave interference from  
customer installed two-way radios.  
There have been some scattered reports in regards to erratic or unexpected movement of one  
or more of the proportionally controlled boom functions of the joystick control system during the  
operation of the customer installed two-way radios.  
Specifically,theSwing,LiftorDipperfunctionsmayoperateataspeedofonefootofmovement

plane tape" can be used in place of the metal sheet for easier installation. this tape is available at most  
electronics or radio equipment sources.  
3.  
Utilize a ground plane antenna. These specially designed antenna utilize the standard central  
radial element and at least two other radials set at 45° angles to the central one. These radials must  
be cut to specific lengths depending on the frequency of the system. Only a professional radio installer  
or retailer should be consulted in regard to the avaialbility and proper installation of these antenna.  
The installation, operation, and resulting effects to the tractor or any attachment due to the  
addition of a radio system to any machine is the responsibility of the machine owner and the radio  
installer. Only trained, profesional radio installers should be utilized.

New Holland has circulated a service bulletin stating that a longer or taller filter is the  
replacement part for the fuel filter and the filter should be changed at the recommended time.  
Alamo Industrial TS Series mount kit components will interfere with the longer / taller filters.  
Please continue using the # 87801634 filter when replacing the fuel filter on the TS Series  
tractors equipped with the Alamo Industrial products. Alamo Industrial attachments do not stress or  
"Work" the tractor engines in a manner that would be considered extreme service. The part #

New Oil Filter Kit P/N 02976069:  
Detailed investigation of recent valve failures revealed that in the vast majority of the  
incidences, the failures are attributable to contamination within the tractor hydraulic systems which  
supply pressure to the control valve. Failure normally take the form of one or more inoperative or  
poorly operating functions. Repair may involve the replacement of the electronic controller for the  
sectionor, inseverecases, thereplacementoftheentirevalve. Particulatecontaminationintheform  
of small gear metal or brass particles created during break-in and operation and are not removed  
during required maintenance of the tractor can enter the valve, this creates leakage due to wear or  
clogging of passageways.  
In response, an in-line pressure filter and fitting kit (Kit P/N 02976069) has been developed  
for installation in the pressure line which delivers oil to the valve. The kit provides all the necessary  
fittings, hardware and instructions to facilitate the correct installation.  
Installation of the Filter Kit will greatly reduce the  
possibility of the occurrence of failures within the Machete  
control valve due to particulate contamination. This con-  
tamination may result from poor maintenance of the tractor  
hydraulic system or other hydraulic system performance  
characteristics or problems.

the tractor. New Machete units received from the factory, or assembled by dealer after S/N MB21-  
01572 & UP or MB24-01245 & Up will have the control valve in a new location. It will no longer be  
mounted on the frame. The Control Valve will be located under the front pump cover in the front of  
the tractor. This change was made to better protect the Valve and its components from debris and  
other possible damage.

Filter Kit to Update Control Valve System (Kit P/N 02977366):  
There is now available for purchase, a filter kit for Machete units that utilize the Apitech valve.  
The Apitech valve was the control valve used before the now current Danfoss valve. You can  
differentiate the type valve in two ways. The first is by serial number. The Machete units PRE-Date  
the following serial numbers, utilize the Apitech Valve: MB21-01109 & Down, MB24-01046 & Down.  
The second way is by visually inspecting the unit. The Apitech valve will have electronic Solenoids  
on both the pressure and return sides of the valve, as well as electronic connections on each  
solenoid. The Danfoss Control Valve only has electronic connectors on one side. Install the Filter as  
described by the Assembly Drawing ( Drawing P/N 02977367) that you will receive when you order  
the Filter Kit (Kit P/N 02977366) for the Machete Unit

Recommended Brands of Hydraulic Oil:  
As of November 10 of 2002, Alamo Industrial ™ changed the specification in regard to the  
recommended hydraulic oil for use in the current Machete Boom and Brahma mounted mowing  
system. This Oil change effects the front mounted 18-gallon oil tank, front mounted pump and motor  
circuit of the Machete Boom.  
This update to the specifications will better protect against the possibility of internal motor wear  
and loss of power.  
To comply with the new specifications, the front tank hydraulic oil should be changed to the  
recommended ISO rated AW 100 hydraulic Oil (Alamo Industrial Part No. 00751758)  
One of the following equivalents can be used as they are equal to the Alamo Industrial ™  
recommended hydraulic Oil.

a random change, which did not affect all tractors. In addition, a specific serial number break does not  
exist to identify the affected units.  
The Tier II pulley can be identified as a 5 spoke design as indicated in the figure above (See Figure 1).  
This pulley must be changed to the tapered lock, solid cast pulley as shown to allow adaptation of the  
required front pump drive system used to power the Alamo Industrial products. (See Figure 2)  
To change the pulley:  
Remove the original pulley retaining bolt, shouldered washer and pulley. (See Figure 1) Clean nose of  
Crankshaft using LOCKTITE® number 7649 clean and cure primer. Place a light layer 2 mm to 3 mm  
(.079 - .118 in.) of LOCKTITE ® brand adhesive number 680 (TY15969) to the leading edge of the  
crankshaft nose.

you installed the Locktite primer and adhesive as described in previous step before you installed the  
pulley, this is very important.
