GEAR DRIVE Proper Shifting Procedures - Gear Drive 2. Place the gear shift lever in 6th gear (Figure 212). IMPORTANT: This is not a “shift on the go” system. The operator must depress the clutch pedal and the tractor must be stopped before shifting to the next gear. Shifting the tractor without the use of the clutch may cause severe damage to the transaxle (Figure 211). Figure 212 3. Figure 211 MVC-292X Disconnect the linkage rod at the transaxle shift arm (Figure 213).
GEAR DRIVE 4. Shift the transaxle to the 6th gear using the transaxle shift arm (Figure 214). Shift Detent Tension Adjustment The detent ball on the shifter in the transaxle must have the proper tension for the transaxle to operate properly. If this tension is not correctly set, the transaxle will either shift hard or correct gear selection will be difficult. To have the proper tension on the detent ball, the index set screw should be ½ turn in from the top of the case (Figure 216).
GEAR DRIVE Adjusting the Brake 1. Check the brake before you adjust it. 2. To increase braking resistance, tighten the brake adjusting nut 1/8 turn clockwise; then check the brake again. Continue this adjusting and checking process until the brake is set properly (Figure 217). Figure 217 3. MVC-303X Push down on the brake pedal to release the parking brake. IMPORTANT: With the parking brake released, the rear wheels must rotate freely when you push the tractor.

ELECTRICAL SYSTEMS The electrical system in the 260 Series Lawn and Garden Tractors differ between Gear Drive and Hydrostatic Drive models. Following is a brief explanation. Gear Drive Models Two things happen when turning the ignition switch to the “START” position. (1) Current flows from the ignition switch through the PTO (Power Take Off) switch, brake switch, neutral switch, seat switch, and activates the interlock relay, which sends voltage to the coil of the starter solenoid.
ELECTRICAL SYSTEMS 2. Switch: Terminals 30, 87, and 87a are actually part of a single pole, double throw (SPDT) switch. Terminal 30 is the common lead. The switch is spring loaded so that 30 and 87a are connected when the coil is not energized. When the coil is energized, the switch is “thrown” and 30 and 87 are connected (Figure 219). Figure 219 4. Connect multimeter (ohms setting) leads to relay terminals 30 and 87a. Apply +12 VDC to terminal 85.
ELECTRICAL SYSTEMS The ignition switch is protected because only a small amount of current is needed to activate the coil. Location The solenoid is located under the front hood, mounted to the firewall of the tractor (Figure 221). Figure 222 Figure 221 MVC-314X XL Solenoid Testing How it Works 1. Disconnect the solenoid from the wiring harness. The solenoid has two primary parts. One is a coil of wire wrapped around an iron core. Whenever 12 volts is applied to the coil, it becomes a magnet.
ELECTRICAL SYSTEMS 4. How It Works You should be able to hear the solenoid switch “click” when you make the connection (Figure 223). D B C D C A Detents inside the switch give it four positions: OFF, LIGHTS (ACCESSORIES), RUN, and START. The START position is spring loaded so the cylinder automatically returns to RUN once the key is released. B A Figure 223 (A) & (B) Coil Terminals Terminals of the ignition switch as viewed from the terminal end.
ELECTRICAL SYSTEMS Testing Location 1. Disconnect the switch from the wiring harness. 2. Verify that continuity exists between the terminals listed for the switch position. Verify that there is NO continuity between terminals not listed for the switch position. The low voltage module is located under the front hood, on the lower end of the front side of the firewall of the tractor (Figure 227).
ELECTRICAL SYSTEMS Testing 1. Before replacing the low voltage module, test the battery to make sure it is fully charged and is in good shape. 2. Next check the charging system of the engine; follow the procedure in the Kohler Engine Service Manual. 3. If the battery checks out and is in good condition and the charging system checks out and is charging properly and the battery light on the dash is on, replace the low voltage module.
ELECTRICAL SYSTEMS Measuring Clutch Current Draw 1. Setting the Air Gap on 1999 and Prior Model 260 Series Tractors Disengage the PTO, set the parking brake, and turn the ignition to OFF. 2. Disconnect the clutch wire connector. 3. Set the multimeter to check amps (10 amp scale). 4. Connect the positive meter lead to the tractor terminal (1) of the clutch wire, Figure 231. 5. Connect the negative meter lead to the corresponding wire terminal (3), Figure 231. 6.
ELECTRICAL SYSTEMS Clutch Burnishing Procedure How it Works The clutch should be burnished as part of the predelivery service, or whenever a new clutch is installed. Burnishing polishes the clutch plate, allowing for smooth clutch engagement. When the PTO switch is pulled out to the “ON” position, contacts inside the switch electrically connect various terminals. One terminal is connected to the wire that goes directly to the electric clutch.
ELECTRICAL SYSTEMS Figure 235 Microswitches 2. Using a multimeter (ohm), connect one meter lead to the “COM” terminal, and other lead to the “NC” terminal. 3. With the switch in the spring loaded “up” position, there should be continuity; the switch is operating properly. Push the button “down”. There should be no continuity; the switch is operating properly. 4. Connect one meter lead to the “COM” terminal and the other lead to the “NO” terminal. 5.
ELECTRICAL SYSTEMS 6. The brake switch on gear model tractors is located under the frame, under the brake pedal (Figure 238). Then move the switch button to the “down” position. If there is continuity, the switch is operating properly (Figure 236). Figure 238 Figure 236 MVC-677X Location 2-27 The parking brake switch is located on the front side of the lower console on both hydro and gear drive tractors (Figure 239).
ELECTRICAL SYSTEMS The neutral switch on 1998 and prior gear drive tractors is located on the upper shift linkage (Figure 240). Figure 240 Location The neutral switch - plunger type - is located under the seat and fender area of the tractor on the right side of the transaxle (Figure 242). 2-29 The neutral switch on 1999 and later gear drive tractors is located on the upper shift linkage (Figure 241). There are two neutral switches mounted together.
ELECTRICAL SYSTEMS Testing Location 1. Disconnect the switch from the wiring harness. 2. Using a multimeter, follow the procedure listed below (Figure 244): The neutral switch is located under the tractor, on the right side of the steering sector mount, above the brake assembly arm (Figure 245). A C B D Figure 245 Figure 244 Neutral Switch MVC-215X How it Works Note: Terminals on actual switch not labeled.
ELECTRICAL SYSTEMS Brake Switch Testing Location 1. Disconnect the switch from the wiring harness. 2. Using a multimeter, follow the procedures listed below (Figure 246): A C B D Figure 246 Brake Switch.doc Note: Terminals on actual switch not labeled.
ELECTRICAL SYSTEMS How It Works When the seat is vacated, the switch is open and there is no continuity between the two terminals. When the seat is occupied the switch closes and there should be continuity between the two terminals. Testing 1. Disconnect the switch from the wiring harness. 2. With a multimeter, check the continuity between the two terminals of the switch. There should be NO continuity. 3.
ELECTRICAL SYSTEMS 2. Pull the PTO electric clutch switch to “ON” (Figure 249). Figure 249 3. 260 Series Tractor Service Manual The “Key Choice” warning light on the dash should come on (Figure 251). Figure 251 MVC-387X Turn the “Key Choice” key and release (Figure 250). Figure 250 4. MVC-389X 5. Move the foot pedal to reverse. On gear drive model tractors, move the gear selector to reverse. 6. The PTO and PTO light on the dash should remain on. 7. Push the PTO switch to “OFF”. 8.
ELECTRICAL SYSTEMS KeyChoice™ Reverse Operating System Switch Reverse Switch (Hydrostatic Models) Purpose Purpose This switch is used in the KeyChoice™ Reverse Operating System circuit. When turned to the ON position, it allows the operator to mow in reverse. This switch works in the KeyChoice™ Reverse Operating System circuit when the mower (PTO) is engaged. How It Works Location The switch is basically an on/off switch spring loaded to return to off position.
ELECTRICAL SYSTEMS 3. Depress the plunger on the switch and check the continuity across the terminals, there should be NO continuity (Figure 254). How It Works When the gear shift selector is moved to the reverse position, the microswitch button is pushed in and the switch contacts open and the electric (PTO) clutch will stop, unless the KeyChoice™ switch has been operated. Testing Follow the same test procedure for the microswitch, page 6 - 9.
ELECTRICAL SYSTEMS Location Testing The KeyChoice™ Reverse Operating Module is located under the front hood, on the inside of the firewall (Figure 257). The KeyChoice™ Reverse Operating System Module must be removed from the wiring harness. Using a multimeter check the following (Figure 258): 4 2 1 3 5 6 Figure 257 MVC-224X Figure 258 NMIR Module How It Works The KeyChoice™ Reverse Operating System Module is made up of several components, such as diodes and relays.
