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

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.
Cylinders that are attracting dust around them is not considered to be leaking. This dust
collecting around them is considered normal.
All Cylinder that are returned as leaking will be pressure tested for leakage to determine the
condition of the Cylinder and its components.

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

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.

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

Researchandexperimentswithmachinesinthefieldhasrevealedthatthisphenomenonisthe
receptionofthesignaltransmittedbytheradiopassingthroughthevariablecontrolsoftheboomcontrol
system. Specifically, the wire harness of the control system acts much like a receiving antenna and
receives the radio signal which sends a false signal through harness.
Eliminationoftheinterferencemaybeobtainedwiththeuseofatleastofthreepossibleoptions:
1.
2.
Remove the radio from the tractor completely.
InstallareflectingplateundertheAntenna. Areflectingplateissimplyathin, flatpieceofmetal
which provides the proper amount of impedance to essentialy reflect the signal emanating down from
the antenna and prevent interference with the valve electronics and tractor functions. Since the
installationrequiresafairlylarge(atleast36"square)area,thespeciallydesignedreflectingor"ground
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.

Control Valve Relocation:
The 2001 Machete will reflect a change in the way some of the components are mounted to
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.
Pump Fiter
Asyoucanseeinfigure1,
the valve is fastened to a plate
that is mounted to the units hy-
draulic tank. The Pressure Filter
was relocated to a bracket on top
of the tank. Both the Pressure
Filter and the Pump Filter are
accessible and can be changed
with minimal effort. Sepaarate

tion is not easily accessible, then
the valve and mounting plate can

In an effort to comply with certain requirements in regard to Tier II Emission Standards, Deere and
Companyinitiatedachangetothecrankshaftpulleyonmanyofthenew6020seriestractors. Thiswas
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.
Installthereplacementpulley(P/N02979857)Ifanypaintinsideofpulleyitneedstoberemoved. Make
certain to align the pulley with crankshaft, install pulley. (See Pulley Figure 3). Do not hammer on
Vibration Damper (Pulley) it must be handled in a way that avoids impact damage. Make certain that
you installed the Locktite primer and adhesive as described in previous step before you installed the
pulley, this is very important.
