  If the starter turns but the engine doesn't start, first, make sure the choke is pulled out and the throttle is properly positioned. Then, check if the fuel tank is empty and, if so, top it up with fuel. If these steps don't work, the spark plug may be defective or dirty, and it should be checked according to the engine manual. If there's still no ignition spark, arrange for a specialist workshop to inspect the ignition system.

What to do if Cub Cadet 13B726HD603 cutter deck does not discharge grass or cuts unevenly?

  If the cutter deck isn't discharging grass or is cutting unevenly, first, increase the throttle, as the engine speed may be too low. If that doesn't solve the issue, reduce your travelling speed. If the problem persists, the cutting blade may be blunt and you should arrange for a specialist workshop to sharpen or replace it.

  If your Cub Cadet lawn mower engine is producing smoke, switch off the device immediately and check the engine oil level, as there might be too much oil in the engine. If the oil level is correct, the engine may be defective, and you should arrange for a specialist workshop to check it.

Why Cub Cadet 13B726HD603 Lawn Mower starter does not turn?
- W
  William BarkerAug 20, 2025
  The starter may not turn for several reasons. First, the safety locking system might be engaged; ensure you're sitting on the driver’s seat, the brake pedal is fully depressed or the parking brake is applied, the cutting mechanism is off, and the grass catcher is properly attached with the discharge channel, flap, or mulch locking part. Also, check if the red cable is connected to the (+) battery terminal and the black cable to the (–) terminal. The battery might be discharged, so charge it. A tripped fuse can also be the cause; replace it, and if it blows again, identify and fix any short-circuit. Finally, a loose earth cable between the engine and frame can prevent starting; ensure it is securely connected.

  If your Cub Cadet lawn mower is experiencing strong vibrations, switch the device off immediately. This could be due to a damaged blade shaft or a defective cutter. Defective parts must be replaced by a specialist workshop.

  If the engine is running but the cutter deck isn't mowing, it's likely that the V-belt is torn. The V-belt must be replaced in a specialist workshop.
