John Deere GT242, GT262 & GT275 Common Problems This Manual Covers
John Deere GT242 gear transmission jumps out of gear or won't engage while mowing
Check the clutch actuating spring free length on page 204; it must measure 31 to 35 mm (1.2 to 1.3 in.), replace it if compressed shorter. Inspect the shift linkage for wear at the detent and lubricate the pivot points. Verify gear backlash does not exceed 0.35 mm (0.014 in.) per page 222; excessive play means shim adjustment or gear replacement.
Manual Section: Gear Power Train p. 203Engine stalls under load or refuses to start on the first few pulls
Pull the spark plug and check the gap against the 0.76 mm (0.030 in.) specification before reinstalling, then torque it to 20 N•m (177 lb-in.). Test cylinder compression; minimum acceptable is 483 kPa (71 psi), and low readings point to worn rings or valves. Work through the troubleshooting procedures, then inspect the in-line fuel filter for debris.
Manual Section: EngineMower deck won't engage the PTO clutch or cuts unevenly across the yard
Inspect the electric PTO clutch air gap and reseat the cap screw; torque to 75 N•m (55 lb-ft) on GT242 and GT262, or 56 N•m (45 lb-ft) on GT275, per the specification on page 16. Check drive belt tension, it should deflect 31 to 35 mm (1.2 to 1.3 in.) under load. Replace a glazed or cracked belt.
Manual Section: Attachments p. 16No lights, no start, and intermittent electrical failures after the machine sits overnight
Check ignition switch continuity and battery voltage at rest; a fully charged battery should read at or above 12.6V. Trace the wiring harness for corrosion at the connectors near the frame rail, common on tractors this age. Reference the electrical wiring diagram to isolate the faulty circuit segment, then clean and dielectric-grease every ground connection.
Manual Section: ElectricalHard to shift smoothly into gear when the engine and transmission are still cold
Check the gear shift lever neutral adjustment per the specification on page 203; linkage out of adjustment causes binding as temperatures drop. Verify the shift detent spring has not fatigued and lubricate the shift rail with the specified gear lubricant. Inspect for gear backlash exceeding 0.35 mm (0.014 in.) as listed on page 222, which points to internal wear.
Manual Section: Gear Power Train p. 203Tractor won't move forward or reverse though the engine runs fine and PTO engages
Check hydrostatic transmission oil level; capacity is 4.3 L (4.7 qts) per the specification on page 254, and verify the oil is not aerated or contaminated. Inspect drive belt condition and tension, and confirm the free wheel valve is fully closed for operation, not left open from towing. Review the hydraulic schematic to trace pressure loss in the charge circuit.
Manual Section: Hydrostatic Power Train p. 253Frequently Asked Questions
What are the torque specs for the blade bolt on John Deere GT262?
