As mentioned earlier, the Cub Cadet ZT1 50 faces several issues in its lifetime. Let us take a look at these issues in detail and how to troubleshoot them easily.

1. Engine Starting Issues

Low battery charge is a common problem that prevents the engine from starting properly. The fuel filters connected to the system become clogged over time as dirt, dust, etc., accumulate and block the fuel flow.

If the fuel is old and stale, it can also cause several issues in the engine. As the fuel becomes stale, it attracts dirt, which causes trouble when starting the engine. And a faulty spark plug is also a possible cause of engine starting trouble as the mechanism remains incomplete.


  • Recharge the battery of the mower or replace it with a new one if the battery is dead
  • Clean the fuel filters properly and install new ones every 3 to 4 months
  • Drain the stale fuel from the engine and refill the tank
  • Repair the broken spark plug and put a new one in its place

2. Poor Cut Quality

Poor cut quality is a common problem that the ZT1 50 users face. The most common cause behind this problem is dull blades. Over time, the blades lose their shine and sharpness due to wear or tear, rust, and many more.

The uneven height of the blades also impacts the cutting quality of the mower. This is because the blades fail to cut the grass in equal and even pieces due to unevenness. Not only that, but the clogged deck also results in uneven grass cutting as the blades will not be able to operate smoothly.


  • Clean the blades and sharpen them appropriately. If the blades’ edges get damaged, replace the blades
  • Adjust the height of the blades properly before you start cutting the grass. This will ensure that the grass cuts properly and evenly
  • Troubleshoot the clogged deck by cleaning all the dirt and debris correctly

3. Transmission Issues

Another major trouble with the Cub Cadet ZT1 50 is transmission problems. Leakage in the transmission fluid tank causes the fluid to escape. This results in the transmission not working properly as the fluid reduces to its required limit.

Difficulty when shifting the gears can be a significant trouble for the users. This trouble typically arises due to worn-out or damaged transmission belts.

A misaligned transmission linkage can also result in trouble. Lack of power in the mower indicates a transmission problem and typically occurs due to low fluid levels.


  • Identify and repair the leakage of the transmission tank and refill the fluid
  • Replace the damaged or worn-out parts with new ones
  • Align the linkage in its correct place
  • Check and refill the tank if the fluids are low

4. Electrical Issues

Blown fuses also impact the performance of the components as it makes the circuit incomplete. A faulty ignition switch is also to blame for electrical issues in the mower. Without the ignition switch, the engine will not be able to start and operate.

Lastly, wiring issues are a major threat to the performance of the ZT1 50. This is because the wires often come loose or get damaged, which prevents the connected component from working efficiently.


  • Check the fuse box and replace the blown fuses to complete the circuit
  • Inspect the ignition switch and secure a new one in its place
  • Examine the wiring connections in the system. Make sure that there are no loose connections and change the damaged wires

5. Blade Engagement Issues

Another significant problem with the ZT1 50 is blade engagement trouble. In case the blade fails to engage properly, it will not be able to cut the grass evenly. The typical cause behind the problem is a loose or damaged belt.

Oftentimes, a faulty electric clutch also causes the issue. If the clutch is faulty, it prevents the blade from engaging, resulting in bad cutting quality. Damaged or loose wiring can also be responsible for this issue.


  • Align the belt properly by checking the diagram or replace it if it is damaged
  • Repair the electric clutch or install a new one
  • Check the wiring properly and change the damaged wires
