Why MTD 607 engine will not crank?
- M
  Melissa CampbellSep 2, 2025
  If your MTD Lawn Mower engine won't crank, there are several potential causes. First, ensure that both the brake pedal and seat safety switches are fully depressed and the PTO lever is disengaged. Check the battery installation, ensuring the negative terminal is connected to the black ground wire and the positive terminal to the red wire going to the solenoid. A dead or weak battery can also prevent cranking; charge it with a 12-volt automotive-type charger. Finally, a blown fuse can be the culprit; refer to page 23 for fuse location and replace it with the correct amperage fuse, after checking for loose connections and shorts in the wiring.

  yharperSep 4, 2025
  If your MTD Lawn Mower engine cranks but doesn't start, make sure the throttle or choke is in the correct starting position as described in the OPERATION section of this manual. Check if the gasoline tank is empty and fill it with clean, fresh fuel. A plugged fuel line or in-line fuel filter can also prevent starting; remove and clean the fuel line and replace the fuel filter if needed. Ensure the spark plug lead is connected and test for spark. If there's no spark, have the engine’s magneto serviced by an authorized engine dealer. A dirty air cleaner may also be the cause, refer to the engine manual packed with your unit.

What to do if my MTD 607 Lawn Mower will not mulch grass?
- T
  Thomas McdowellSep 6, 2025
  If your MTD Lawn Mower is not mulching grass effectively, consider these possible causes: * The engine speed may be too low. Place the throttle in the FAST (rabbit) position. * The grass might be wet. Avoid mowing when the grass is wet; wait until it's dry. * The grass might be excessively high. Mow once at a high cutting height, then mow again at the desired height, or make a narrower cutting swath. * The blade might be dull. Sharpen or replace the blade.
