NEW LAWN TRACTOR STEERING
A new steering system was phased in during 2001on lawn tractors. The new steering system issmoother and requires less effort to turn the steer-ing wheel. The assembly mount is held by fourself tapping screws from the underside. A washeris placed on the steering shaft and is retained bythe steering clip.NOTE: The new steering cannot be used to re-place the old steering system because the chasisare made differently.

Replaces this Steering System on LawnTractors
6
There will be a transition to a new seat system this year. The new seat will have two shoulder bolts thatwill slide in two slots in a new wider seat pan. Because of the wider seat pan, the seat pivot bracket willbe wider. The old seat pan had one slot and two tracks allowing the seat to slide forward and backward.

TRACTOR BRAKE ADJUSTMENTS
NOTE: Any time you do anything with the brake, the brake must be tested. The tractor must stop within six ( 6 ) feet on alevel paved surface from the fastest speed. Test the tractor to hold itself on a 15 degree slope with the parking brake.If the brake does not pass tests, the brake puck clearance must be adjusted tighter. There is a slope guide in the tractorowners manuals.NOTE: If excessive wear is found on the brake disc or the brake pucks, these parts should be replaced before adjust-ments are made. Use a new cotter pin to lock the castle nut after adjustment.* HG 0500-0650-0750 insert the feelerguage between the brake rotor and stator rings from underneath. Be sure to fully insert the gauge through the lower andthen the upper part of the rotor and stator rings.

DLT PEDAL AUTOMATIC REVERSE COMPLAINTSDLT tractors with Pedal Control Automatic mayhave complaints of slow reverse or no reverseif the correct installation procedure is not used.Tighten fasteners in this sequence:
Loosely assemble all screws or boltsand nuts that hold transaxle.
Tighten the screws labeled 1 that holdthe transaxle to the Torque Strap.
Tighten the screws labeled 2 that holdthe Torque Strap to the Chasis.
Tighten the nuts and bolts labeled 3that hold the axle supports to the rearmounting brackets.
DLT FREEWHEEL CONTROL ROD
NOTE: If this procedure does not increase the reverse speed. Use a straight edge to check the TorqueStrap. If there is a severe bow toward the rear, the transaxle is located too far rearward.
2001FREEWHEELROD SPRING
2002 DLTFREEWHEELROD SPRING
BYPASSVALVE
The attachment of the spring on the Freewheel Control Rod to the Bypass Valve has been improved onDLT tractors. The end of the spring is formed differently and a 179422 washer and 4497H retainerspring now retain it to the Bypass Valve.
The linkage going from the Foot Pedals to the Automatic Transaxle control arm was retained with 4497HRetainer Springs. If improperly installed, the 4497H can keep the linkage from the full range ofmovement needed. The tractor may not go as fast in forward or reverse as it can. In 2002 a change ismade to a 178062 Clip so it cannot be installed improperly.

The 179433 Reverse Pedal now comes with thePedal , Pedal Cover, and the Screw installed. Oneshoulder bolt under the footpad can be removedand used to install a new reverse pedalassembly.
Changes have been made to improve the belt guideon the 6 speed lawn tractor transaxles. The guideis now closer to the pulley to better retain the beltand improve belt disengagement characteristics.To identify the belt guides, the loop for the screwthat retains the belt guide is in the reversedirection on the 178394. The previous number was173898.
GARDEN TRACTOR LIFT ASSIST SPRING CHANGE
The Lift Assist Spring Assembly on GardenTractors will now be part of the Sleeve Hitch Kit,beginning in 2002. A slot has been added to thebracket on the Lift Shaft. The end of the spring ishooked into the slot . A bolt, nut , and washer arethen installed to hold the assist spring in the properposition. The bracket at the other end of the springwill need to be attached to the chasis. Completeinstructions will be included in the Sleeve HitchKit.

ELECTRICAL COMPONENT IMPROVEMENTS FOR 2002
A lock tab is added to snap in InterlockSwitches for 2002. The new switch willwork for the switches without a tab.
176137 SWITCH NO-NO BLACK / GRAY
176138 SWITCH NO-NC GRAY
A new interlock switch at the footpedal will be usedwith tractors equipped with POWERLINK. It ispart # 181884. This is a NO-NO-NO switch. Theadditional set of contacts are needed so thatPOWERLINK cannot function unless the ParkingBrake is engaged.
The reset switch used with POWERLINK is a part# 110712X. This switch was used in the past as atractor headlight switch.
There will be a new Battery Box 176689 under theseat on lawn tractors. Where this battery box isused, a 180499 Battery Terminal Cover must beinstalled where the red battery cable attaches tothe positive battery terminal.
Snap in retainers will be attached to the electricalharness to give more places where the harness isheld to the chasis.

If the fuse is blown, only replace it with the correct fuse. Lawn Tractors with a 15 AMP fuse can use a 20 AMP fuse.Garden Tractors use 30AMP fuse (green).Lawn Tractors use 20 AMP fuse (yellow).
Check condition of battery case?
Check for good battery connections?
Is the battery clean?
If the battery is 12.3 - 12.6 DC Volts, thebattery is acceptable for normal use.
If voltage is 12.6 DC Volts or more thebattery is fully charged.
Check battery for D.C. voltage?
Always wear eye protectionwhen working with a battery.You should also wear plasticgloves and apron when incontact with the battery.
Correct any problems found with wiresor connectors. Look at the terminals inthe connector and the switch to see ifthe connector is correctly located onthe switch.
CAUTION: Do not wear watches or jewelry while working near electrical components.
If the case is cracked or leaking acid,properly discard battery with due care.
If the connections are bad or corroded,you will not get a consistent supply ofelectricity. Use a scraper and a wirebrush to clean the terminals. Afterinstalling the cables on the batteryterminals, apply a non-metallic greaseto both to reduce new corrosion.
If the battery is dirty, it will leakelectrical current and slowly discharge.Use a paper towel to clean the batterycase with baking soda and water.
Check the fuse.
Go to tests for electricalgrounds on the next page.
TRACTOR ELECTRICAL TROUBLESHOOTING BASICS
START HERE If the battery is 11.7 to 12.2 DC Volts,the battery needs to be charged.��Check electrical charging system
on page 13 .
If the battery is below 11.7 DC Volts,the battery may be good. However, itis not cost effective to charge and testwhile on an outside service call.Replace the battery. Dischargedbatteries are not covered by warranty.
Check electrical connectors and wires.Are any wires damaged or hanging loose?Are connectors plugged in the properway?

TRACTOR ELECTRICAL TROUBLESHOOTING BASICS
Electrical Grounds are necessary tomake a complete electrical path so acircuit can function. Use an electricalmeter for this check.
If you get a reading greater than0.5 OHMS, you will need to track downthe poor connection. Start at thebattery cable and check componentsgoing toward the item that is notworking. When you find a place wherethe resistance increases, you have aplace where an electrical connectionmust be improved.
If you get a reading of 0.5 OHMS orless grounds are good, you can stop.
Hold the other meter probe to a cleanmetallic surface on the item that isnot functioning.
Hold one meter probe to the negativebattery post.
Move the selector on your meter to theOHMS or R X 1 position. Connect theleads to the meter for OHMS.
A reading of more than 0.5 OHMSindicates a poor ground that resists thepassage of electricity. You will need toimprove the connections between parts toget the resistance to electrical passagebelow 0.5 OHMS. Do this by scrapingwhere electrical contact is made betweenparts, until the finish is bright metallic.EXAMPLE: Where the eyelet for the blackbattery cable meets the chassis.
Check electrical charging system.
Start engine, raise engine to fastestRPM for two full minutes.Check voltage at battery.
With engine off check the battery voltage. Note the DC Voltage reading.
START HERE
Move selector on meter to DC Voltsor scale for 12 DCV. Place leads inpositions for Voltage.
START HERE
If the DC Voltage reading is thesame as the reading noted with theengine off, the charging systemis not working, or is not connected tothe battery. Refer to electricalsection of engine manufacturer’smanual to further diagnose chargingsystem.
If the reading is above 12.8 DC Volts,the charging system is working.Discontinue charging tests.
If the tractor has relays, test the relayson page 16. If any of the relays test bad,replace the relay and test the chargingsystem again. In some wire harnesses,a relay makes an electrical connectionbetween the engine charging systemand the battery.
NOTE: There are two starwashers usedto cut through the paint to make a goodground. One is at one of the screws thatholds the engine to the chassis. Theother is where the black battery cable isheld the chassis.

START HERECheck starting circuit to SOLENOID
The starting circuit is identified by awhite wire. Remove from the solenoidthe connector for the white wire. Placea meter probe into the white wireconnector. Move the meter selector toDC Volts or range that includes 12VDC.Check to see that meter probe leads areinstaled in correct positions. Attachother meter probe to a good ground.
Sit on tractor seat. Place mowercontrol in disengaged position andhold footpedal to lowest position.Watch meter reading while turningignition switch to ‘Start’ position.
If meter shows 0.0 DCV with ignitionswitch in ‘Off’ position and about12 DCV in ‘Start’ position, the circuitis functioning properly. The wiring,connections, ignition switch, interlockswitchs, or PTO switch are all good.
If the meter shows 0.0 DCV in the ‘Start’position, there is a problem with wiring,connections, ignition switch, interlockswitchs, or PTO switch in this circuit.It will be necessary to evaluate eachitem in the circuit until the item causingthe problem is found. There is a 150834diagnostic jumper kit that will allow theswitches to be evaluated quickly.
If the resistance reading is less than0.5 OHMS, the solenoid ground isgood. Test solenoid on page 15.
There is a 148691 TerminalConnector Kit available. Itincludes many of the connectors,terminals, and other parts usedin the tractor wire harness.The kit includes butt spliceconnectors for repairing wiresand 30 AMP fuses.
There is a Diagnostic Jumper Kit150834 available. It includesjumper wires, a heavy duty jumpercable, a circuit breaker, and aninstruction sheet. The circuitbreaker can be plugged into thefuse holder. This eliminatesblown fuses while looking forshort circuits. The jumper wiresare used to determine whichswitch is not functioning.
The ground wires are identified by ablack wire. Remove from the solenoidthe connector for the black wire.Place a meter probe into theblack wire connector. Move the meterselector to DC OHMS or range R x 1.Check to see that meter probe leadsare instaled in correct positions.Attach other meter probe to thenegative ( - ) post of the battery.

Move the meterselector to DC OHMS or range R x 1.Check to see that meter probe leadsare instaled in correct positions.Attach other meter probe to thenegative ( - ) post of the battery.
START HERECheck ‘ground’ for solenoid.
If the resistance reading is more than0.5 OHMS, one reason the solenoid isnot working is a bad ground.�Correct ground problem.�Connect everything and try solenoid.

Step # 1.
1. Place meter probes on battery terminals. Ifthe reading is 12.2 VDC or more, proceedto the next step. If the reading is below12.2 VDC, charge or replace the battery withone that has at least12.2 V DC.
Step # 2.
1. Connect negative (black) meter lead to thebattery negative (-) terminal.
2. Connect the positive (red) meter lead to the‘hot’ terminal of the solenoid.
3. Note the voltage reading.
Step # 3.
1. Keep the meter selector in the sameposition and the negative meter leadconnected to the battery negative terminal.
2. Connect the positive (red) meter lead to theend of the cable normally connected to thestarter motor.
3. Engage the parking brake and turn theignition switch to the “START” position.
4. Note the voltage reading.5. If the voltage drop is more than 0.50 VDC
between the two noted readings, thesolenoid or the starter cable is suspect.Replace the solenoid.
6. Re-install the red cable to the starter motor.If the solenoid checks acceptable and thestarter does not crank, check for clean tightbattery connections and check the groundsfor the battery and the engine.
· Remove the red cable from the engine starter motor before testing.· Place digital meter selector on D.C. Voltage scale that includes 13 Volts.

EZ WALK MOWERS - NEW FOR 2002
There is an EZ Walk drive system for both frontdrive and rear drive mowers for 2002. The EZWalk system allows the customer to control thespeed of the self propel system using a drivecontrol lever in front of their right hand. When thedrive control lever is released the mower stops.As the operator holds down the operator presencecontrol bar and pulls the drive control lever, themower self propel starts to drive. The tighter theoperator pulls the drive control lever toward thehandle, the faster the mower goes up to maximumspeed. Both front drive and rear drive models have21” cutting paths.The transmission access is thesame as other rear drive and front drive modelsfor the last few years. Some areas with whichyou will need to familiarize yourself are:
Drive Cable Adjustment procedureDrive Cable Replacement procedureDrive pinion operation and servicing
FRONT DRIVE
DRIVE CONTROL LEVER
OPERATOR PRESENCE BAR
REAR DRIVE
DRIVE CONTROL LEVER
OPERATOR PRESENCE BAR
DRIVE CABLE ADJUSTMENTOver time, the drive control system maybecome “loose”, resulting in a decrease in speed.There is a button on the underside of the drive controlhousing to increase tension on the drive cable.Proceed as follows:1. With engine ‘off’, disconnect spark plug wire
from spark plug.2. Pull drive control lever ALL THE WAY BACK to
the handle.3. Push button on underside of drive control.
While holding button in, return drive controllever to disengaged position, ALL THE WAYFORWARD.NOTE: Do not ratchet the adjustment.
4. Release button.5. Operate mower to test drive speed. If
condition becomes worse after the above steps(forward speed has become slower), yoursystem was not “loose”. Repeating the abovesteps will return your unit to the properadjustment and speed.
6. If condition fails to improve after the above steps(forward speed remains the same), your drivebelt is worn and should be replaced.

E Z WALK - DRIVE PINION OPERATIONTo access the Drive Pinion Assembly on the mowerremove the drive wheel. The same Drive Pinionsused on the front drive EZ Walk system are usedon the rear drive EZ Walk system.
DUST COVER
Only the complete Drive Pinion Assembly will beavailable from repair parts . The right side DrivePinion Assembly is part number 176412 and isheld with white plastic wrap. The left side DrivePinion Assembly is part number 176413 and isheld with clear plastic wrap. The plastic wrap isremoved by pulling between the perforations afterthe pinion assembly is installed on the gearboxdrive shaft.
Only the Drive Retainer is different between theright and left side pinion assemblies. These aremirror image parts except for the letter to desig-nate ‘R’ for right or ‘L’ for left.If you have a wheelthat will not drive, first check to see if the drive beltis wet. If not, remove the pinion assemblies andcheck to see if the correct Drive Retainer is onthat side.
HOW IT WORKS: The pinion assemblies aremounted on the gearbox drive shaft. When thereis no power to the gearbox shaft, the Torsion Springholds the Pawl in the disengaged position. Whenthere is power to the gearbox shaft, the frictionbetween the bearing support and the drive discovercomes the Torsion Spring, and the Pawl canengage one of the three TABs inside the PinionGear. You can disassemble these parts to removecontamination. However, be very careful with theTorsion Spring. Any kinks or bends will keep it fromfunctioning properly.

E Z WALK - DRIVE PINION SERVICING
The Drive Pinion Assembly can be disassembledand cleaned of contamination. Remove the PinionAssembly as a complete unit by grabbing the Fric-tion Seal with your fingers, keeping pressure onthe Pinion Gear. This will allow you to inspect theassembly as it was on the mower. When assem-bling, the projection on the Pawl must go into theopening on the Drive Disc.
NOTE: No lubrication should be used on parts of the drive pinion assembly or the system may notdrive. This includes the areas where the Friction Seal touches the Drive Disc and the Pinion Gear.The Friction Seal must set over the bearing support.NOTE: Care must be taken not to change the shape of the Torsion Spring or the pinion will either notdrive or not allow the operator to pull backwards. To increase the durability of the torsion spring, it iszinc plated to reduce corrosion.
NEW GEARBOX FOR FRONT DRIVE E ZWALKThe EZ Walk front drive gearbox appears
similar to gearbox for the rear drive,but is smaller.
174915 GEARBOX
A new 179606 blade adapter is used with the E ZWalk front drive when an engine spacer ring is usedwith Briggs or Tecumseh engines. The differencebetween the blade adapters in use are how far thecrankshaft goes into the adapter. Use of a bladeadapter other than the one specified in the partslisting can cause the mower not to meet standardsfor industry or CPSC.
