I've had this compact tractor since new. The two-stage clutch has always been really hard to use and slows the operation down. The clutch linkage is set as the owner's manual specifies, but I have to use extreme care when starting forward or it lurches forward. If the clutch pedal isn't depressed at least half way, gears will grind. Then when raising the pedal, engagement isn't as gradual as it should be and the tractor lurches forward. Is there any way to lengthen the pedal range between disengage and engage?
