TROUBLE SHOOTING 6.1 MOWER PULLING LEFT OR RIGHT. a) Check idler arm pulleys and drive sheaves for mud and/or grass buildup. Check for proper scraper position. See 5.2.4. b) Check to be sure idler arms pivot freely, if not, lubricate idler pivots. c) Check for worn drive belts. NOTE: Wheel drive belts should be replaced as a set. A new belt should not be mixed with a worn belt. d) Check drive linkage adjustment - See 3.8.5. e) Check for proper tire pressure in drive tires. Recommended tire pressure for the drive tires is 12 to 16 psi. Higher pressures may be used in the tire on the side that it pulls to (up to 28 psi). Note: Different pressures may make mower cut unevenly. 6.2 MOWER CUTS UNEVENLY. a) Check the drive tire pressure and tire circumference. See 5.1.9. A more uniform cutting height may be obtained with higher tire pressure on rough terrain. A lower tire pressure provides more flotation. b) Check blade spacers, axle positions, and front caster spacers. They must be equal on each blade. c) Check caster mounting brackets to be sure all bolts are tight. d) Check blades tip to tip for straightness. (They should be within 3/16" or one blade width from being in line.) 6.3 BLADES DO NOT STOP WHEN DISENGAGED. Check belt guides to see that they are properly set. See Belt Guide Adjustment 5.2.7. 6.4 ENGINE WILL NOT START. a) Refer to Section 4.3.2 and follow directions to make sure engine is being properly choked. b) Make sure transmission is in "true neutral" position. See Sections 3.8.4(c). c) Check that the blades are disengaged and the blade switch is depressed (See Section 5.2.12). d) Check that there is fuel in the tank and that the fuel valve is open. e) Check that the spark plug wire(s) is/are properly connected. f) Check for loose or faulty wiring connections. g) Check for corrosion at all wiring connections. Even minor corrosion may cause a faulty connection. Clean connector terminals thoroughly, apply dielectric grease and reconnect. - 32 NOTE: After carefully checking the previous steps, attempt to start the engine. If it does not start, contact your authorized Exmark service dealer. ENGINE TROUBLESHOOTING When a problem occurs, do not overlook the simple causes. For example, starting problems could be caused by an empty fuel tank, key switch not "ON" etc. The following tables list some common causes of troubles. Do not attempt to service or replace major items or any items that call for special timing or adjustment procedures (governor, valves, etc.). Have this work done by your Engine Service Dealer.
