1. Hustler mower won’t start

Occasionally, the Hustler Raptor SD engine may refuse to start. And even when it starts, it may not continue running.

This problem could happen when the tractor is low on fuel or when the spark plug is not connected.

Putting the wrong fuel in the tank or having dirty fuel filters may cause a problem. In addition, if the choke is off, the tractor may not start.

Luckily, some of these issues are minor, so finding an appropriate solution will allow you to fix the problem and go about your mowing tasks uninterrupted.


  • Check the fuel level and fill the tank if low. But ensure you fill the tank with the correct and recommended fuel. Sometimes, old and dirty combustion fluid will make it hard for the mower to start. Replacing the fuel is the ultimate solution.
  • When the spark plug is faulty, you will likely have a big problem starting your mower. Luckily, checking and cleaning the spark plug could solve the problem. Also, the plug wears out due to continued use. So, you may need to replace it and maintain it well.
  • If the fuel and air filters are dirty, cleaning them could allow fuel and air to enter the combustion chamber and burn. However, if they are clogged and worn out, you must replace them. Also, ensure to change the oil after 200 hours of use.

2. Blades Do Not Rotate

The mower blades may only rotate if the blade controls are engaged. Similarly, the deck belt may not spin the edge if it breaks.

Thus, removing debris built up and inspecting the belt for damage may solve the problem. But if the belt snaps, consider replacing it.

Besides the deck belt, you may also need to check the engine and the crankshaft. Typically, the belt receives energy from the crankshaft.

A lousy safety switch may also prevent the blades from rotating. Lawnmowers come with safety switches that stop the edges from turning.

If the buttons trip, they may not offer this function. Such buttons are attached to the clutch or the brakes; therefore, when they disable the clutch, it stops the blades from rotating.


  • Remove debris or grass that may jam the belt system.
  • Replace the belt if broken.
  • Check the clutch and engage the controls.
  • Adjust or replace the clutch if worn out.
  • Check the electrical connection, especially the wires to the clutch.

3. Loss of Power

Sometimes, the lawn mower loses power while cutting. This problem could result from clogged air filters, contaminated or stale gas or blocked fuel filter.

Also, if the engine oil is dirty or too little, it could lead to a loss of power. Sometimes, when the essential carburetor air does not reach the engine, it may result in loss of power.

When the air filter is clogged, it may not let air get into the engine. So combustion will not take place. Besides, a dirty and clogged filter will not remove the dirt and allow debris into the engine.

This may harm the engine. Not that clogged air filters reduce the volume of air that gets into the carburettor. Eventually, the machine starts losing power and will struggle to run.

Tipping the mower the wrong way during maintenance may make the engine oil leak into the crankcase and eventually get into the air filter.

A soaked air filter will not allow air to pass through and quickly make the engine lose its power.


  • Clean the air filter or replace it altogether.
  • Tighten the blade spindle.
  • Replace the spindles.

4. Uneven Cuts

If your mower streaks, scalps and cuts your lawn unevenly, it is a sign of some problem. Firstly, the blades may be dull, or the edges may be bent.

The more will cut the grass unevenly when its deck is not level or when the spindle is bent. Also, it will not cut the grass if the tires are flat.


  • Sharpen the blades if they are blunt.
  • Adjust and level the deck.
  • Fix anti-scalp wheel height.
  • Adjust the zero turn tire pressure.
  • Consult a dealer or a mechanic in case of a bent blade spindle.

5. Grass Discharge Problem

Although this is not among the major raptor sd problems, it will nevertheless inconvenience you.

The grass will hang on the deck or refuse to discharge the chute. This is not a problem that could happen if the engine RPM is low or when the tier is higher in the front.


  • Do not mow wet grass.
  • Mow at most two and a half inches in height.
  • Reduce the speed of mowing.
  • Move to gator G5 blades up.

6. Throwing of Hydro Belt

Problems with the drive belt could make the belt to keep come off the mower while cutting grass or riding. When the belt comes off, the blades will not rotate.

The strap is likely to come off if the mounting system is problematic or because of an uneven deck. Similarly, it could result from a broken belt, debris build-up, or drive pulley’s loose belt.


  • Remove the dirt using a piece of cloth.
  • Check if the deck is mounted correctly.
  • Check for cracks and fraying.
  • Check if the drive pulleys are ok.

7. Traction Issues When Mowing Down the Slope

The Hustler Raptor SD suffers from traction issues. If riding downhill, the tractor will slide even when moving slowly.

There are two possible causes of this problem. Firstly, if the tires are incorrectly inflated, you will likely experience a traction issue.


  • Try to inflate the tires.
  • The mowers design could be problematic.

How to level pitch of deck on hustler mower

To level the pitch of the deck on your Hustler mower, you can follow these actionable steps:

  1. Preparation: Park the mower on a flat and level surface. Ensure the engine is turned off and the parking brake is safely engaged.
  2. Measurement: Measure the distance from the ground to the blade’s tip on one side of the deck. Note down the measurement.
  3. Adjusting the Deck: Locate the deck leveling adjustment mechanisms on each side of the deck. These mechanisms may vary depending on the specific model of your Hustler mower. They are typically found near the front and rear of the deck.
  4. Raising or Lowering: Use a wrench or a suitable tool to turn the adjustment mechanisms. If the measurement taken in step 2 shows that one side is higher than the other, adjust the corresponding side’s mechanism to raise or lower it as needed.
  5. Re-measurement: After making adjustments, measure the blade tip height on both sides of the deck again to ensure they are level. Repeat the adjustment process if necessary until both sides are at the desired level.
  6. Tightening: Once the deck is properly leveled, securely tighten the adjustment mechanisms to hold the deck in place.
  7. Test Run: Start the mower and engage the blades. Verify that the cutting performance is even and consistent across the entire cutting width of the deck. Observe the mowing pattern to ensure a clean and uniform cut.
