John Deere 260, 270 Common Problems This Manual Covers
Drive weak or one side slow
A skid steer that pulls to one side, creeps, or lacks pushing power usually has a hydrostatic pump, charge pressure, or drive motor issue. The drive system procedures cover pressure testing and adjustment.
Manual Section: Hydrostatic Drive SystemBucket or boom settles
Loader arms that drift down on their own point to worn valve spools or leaking lift cylinders. The hydraulic procedures cover pressure checks and cylinder rebuild.
Manual Section: Hydraulic SystemHard starting or rough running
Difficult starts, low power, or uneven running are diagnosed through compression, fuel delivery, and valve clearance. The engine section carries the tests and overhaul steps.
Manual Section: EngineRuns hot during heavy work
Overheating under load often traces to a plugged radiator, a worn water pump, or a stuck thermostat. The cooling section covers inspection and replacement.
Manual Section: Cooling SystemNo start or electrical faults
A no crank condition or intermittent electrical trouble is worked back to the battery, starter circuit, and wiring. The electrical section covers the checks and repairs.
