Hustler Mowers: 13 Causes of Poor or Uneven Cutting

You’re mowing the lawn and you suddenly realize it doesn’t look as well as usual. This can be an indication of a parts failure and an aesthetic problem with the grass.

Low tire pressure; a dull, crooked, or imbalanced blade; a faulty bearing in the spindle housing or pulley; a frayed deck belt; or a cracked deck shell are all possible causes of a poor or uneven cut on a Hustler lawn mower.

An uneven cut might also result from operating your Hustler mower with a slow engine speed or a fast ground speed.

The ignition key and spark plug wires must be removed from the mower before any troubleshooting or repairs can be made to the cutting mechanism. Let everything come to a complete stop first. Be sure you observe all of the Huster’s recommended safety measures.

Your Hustler Mower Does an Uneven or Poor Job at Cutting

Low Tire Pressure On Hustler Lawnmower

It’s easy to blame the mower deck when you have issues getting a clean cut. Check the tire pressures on your Hustler mower deck before making any other modifications.

Inadequate tire pressure can cause the mower deck to tilt, resulting in an uneven cut.

Don’t skip over this important procedure. Doing so could end up adding to your workload. You may have to backtrack if you begin adjusting the mower’s deck to level it before inspecting the tires and discover a flat tire.

Hustler Lawn Mower Blade Worn

When the blade on a Hustler mower gets too worn, you’ll see uncut swaths of grass in your yard. This is because the metal of the blade is being worn down by dirt and particles that have been drawn into the mower deck.

Wear can’t be avoided in any manner. It happens all the time.

Inspect the mower blade for:

Sail blade wear

  • One of the blade’s upper surfaces serves as a sail. The component that rotates beneath the deck and helps generate wind when the blade is in motion.
  • Suction created by air currents and the deck’s surface lifts the grass to a uniform height before cutting.
  • When the sail becomes thinner than the blade’s center, it’s time to get a new one.

Blades with frayed tips

  • The blades could tear off little pieces of grass.
  • Blade with rounded tips has to be changed.

Dull knife’s edge

  • The grass will not be cut precisely.
  • Could wind up doing nothing more than shredding the grass to shreds. After being mowed, the grass may start to turn brown at the tips.
  • If a dull blade is otherwise in good shape, you should consider sharpening it.
  • If your blade is damaged or has gouges that can’t be sharpened out, you should replace it.

Blade of Hustler Mower Is Damaged

A poor, uneven cut can be produced by even a slightly bent blade. When a Hustler mower’s blade collides with something solid, it might become bent.

The force of the impact might be so tremendous that you can feel the shockwave and hear the metal on metal sound effect. You are obviously aware that something is wrong and that you need to inspect your deck for a possibly bent blade or other damage.

Sometimes the impact is minor, and you wouldn’t dream of checking for a bent Hustler blade if you didn’t have to. If you’re having trouble with your cuts, you should inspect your blades for damage in addition to checking their wear.

A crooked mower blade can be identified in a couple of different ways. The mower blade must be removed from one approach, but not the other.

If you suspect a bent blade, this is an excellent opportunity to remove the blade and inspect the spindle housing for any signs of damage. The next section contains the necessary instructions.

Check for a Damaged Hustler by Removing the Blade

Get underneath the mower deck without risking injury. The mower deck may need to be detached from your lawn tractor. Take it off and set it on top of a replacement mower blade.

Replace the mower blade if the blades don’t line up properly and there are gaps.

Determine If Your Hustler Blade Is Curved Without Removing It

Measure the distance from the floor to the tip of the blade with the Hustler parked on a level surface.

Then, turn the blade around so the opposite side is facing you, and take a measurement from the floor to the blade’s tip. If the discrepancy between the two measures is more than 1/8″, you will need to get a new mower blade.

Never try to correct a crooked mower blade.

Attempting to straighten your Hustler blade and save some cash is quite appealing. When a blade is straightened, the metal is weakened and becomes less durable. Your blade’s metal is prone to split and break off at this vulnerable spot.

When your blades are spinning at high speeds, this becomes a highly risky situation. When a Hustler blade is straightened, it might do harm to nearby humans, animals, and property.

Inadequate Blade Balancing and/or Installation on Hustler Lawnmowers

Uneven mowing might result from poorly balanced or mounted blades on your Hustler mower. Blades must be installed with the proper hardware in accordance with the instructions in the user handbook.

Mower blades should be adjusted before being installed. This necessitates that the blade’s weight be uniform from tip to handle.

Normal use can cause uneven wear on a blade, which might throw off its balance. The procedure of honing the blade might also throw it off balance. When more material is removed from one side than the other, this occurs.

Check the blade’s balance with a blade balancer. It’s a low-priced gadget that prevents engine damage, vibration, and uneven cutting.

If one end of your blade is significantly heavier than the other, you can lighten it by shaving off some metal.

Hanging the blade from a nail that has been affixed to the wall with the head jutting out by an inch or so is another way to ensure that the blade is perfectly balanced.

The blade’s bottom end can be brought to a level position by removing metal there.

Hustler’s Spindle is Broken or the Bearing Is Faulty

If something is wrong with your spindle housing, the blade will make an extra movement, causing the wheel to wobble. When traveling at high speeds, this might generate a severe vibration that ruins the cut.

Grab both ends of a blade and rock it up and down to inspect for damage to the spindle housing. You’re looking for any slack or room to maneuver.

Keep an ear out for a knocking sound. If you experience either of these, it’s time to take apart your spindle and inspect the bearing and spindle for damage.

Grass Clippings Clog the Deck of the Hustler Lawn Mower

It’s impossible to avoid. Grass clippings, dirt, and other particles eventually clog the deck of every mower. Because of this, less room is required under the deck to get the same level of airflow and suction.

When there isn’t enough suction to raise the grass, you’ll get a poor cut.

In addition to causing your engine to work harder or even shut down, a buildup of dirt and grass clippings is hazardous for it.

Regularly scraping your mower deck will keep this from happening. Mower decks tend to become clogged more quickly with wet grass than with dry grass.

Mower’s tire tracks are easily visible in the damp grass. Grass should not be mowed if it is moist. If you must mow, make careful to scrape the deck afterwards.

Spraying the area with silicone or Teflon may help reduce the quantity of material that gets trapped under the deck.

Nothing on the market will guarantee that dirt and grass clippings won’t become stuck to the underside of a Hustler deck, but this product can help reduce the amount of adhesion.

Hustler Lawnmower Deck Is Uneven

If one side of your mower deck is higher than the other, the cut will be lopsided. If the deck is not level from side to side, take measurements as instructed in your Hustler operator’s manual and make the appropriate adjustments.

To set the right rake, consult the handbook and make the appropriate changes. The rake describes the angle at which the deck slopes from front to back. Many decks have a modest elevation difference between the front and back.

The specific model of your Hustler deck determines the range of possible adjustments and dimensions. Because of this, please refer to the manual for guidance.

Faulty Deck Belt or Pulleys on Your Hustler Lawnmower

Your belt will slip off the pulleys if it is too stretched or worn. This can reduce the speed at which the blade spins, leading to an uneven cut.

Examine the Hustler belt you have for any signs of wear. This includes things like cracking, shredding, and a glossy glazed look.

Another indication of a worn belt is when it no longer fits snugly within the pulleys’ grooves. If you notice any of these issues with your Hustler belt, it’s time to get a new one.

Pulleys are the next thing you should inspect. A reliable pulley will not move around and will be perpendicular to your Hustler deck.

When a pulley’s bearing wears out, it can cause the pulley to wiggle, which can make the deck move from side to side.

Turn your hand pulley slowly. Check the bearing for noise and resistance using your fingers and ears. If either of these issues arises, it’s time to swap out the bearing.

The pulley assembly itself may need to be replaced, or perhaps only the bearings. It varies by make and model.

Keeping the Engine RPM Low on Your Hustler Mower

The sharpness of the cut varies with the velocity of the blade’s tip. If you want to get your Hustler lawn mower’s deck spinning at fast rates, you need to crank up the engine to its highest setting.

When utilizing the mower’s cutting deck, you should always have it running at maximum speed.

Bring your mower into a Hustler dealer or a small engine repair shop if full throttle isn’t producing the same amount of power as before.

Mowing Your Hustler Too Fast

When using a Hustler mower, it’s important to take the weather and terrain into account. Cutting thick, tall, or wet grass places a greater demand on the engine of your Hustler.

If you want a nicer cut in these weather circumstances, you should reduce your speed while running the mower.

If you move too quickly across your lawn, the mower may push over the grass instead of giving it enough time to stand up tall under the deck for a clean cut.

Your Hustler Mower Is Overlapping Wrong

When time is of the essence, as it often is, I recommend making your roads as wide as possible to maximize efficiency.

When I attempt this, I inevitably discover patches of unmowed grass where I failed to properly overlap my cuts.

Getting a feel for how much overlap is necessary for a good cut can take a few passes with a new mower.

Broken Deck Shell on Hustler Lawnmower

Accidental contact with a post, tree, or building can cause serious damage to the deck shell.

A terrible slash can be the result of a damaged or modified Hustler deck shell. Your deck shell has to be fixed or replaced if it’s beyond repair.

If fixing your mower deck will need you to replace the deck shell, you should probably just acquire a new one.

In certain cases, the cost of replacing just the deck shell is comparable to that of rebuilding the entire deck.

This is especially true once you factor in the time and effort required to transfer deck parts from one deck to another deck shell. The age of your mower and the cost of the repair should be taken into account for an educated selection.

Uneven Lawn

If you have molehills or other uneven places in your yard, your mower may scalp those locations. Lawns that have been leveled are easier to mow. While this may be true, not everyone has access to a perfectly level lawn.

A lawn roller can be used to smooth out uneven spots and flatten your grass. A weighted roller is what we call a lawn roller.

Mowing with a Hustler mower equipped with a wide format deck will scalp the yard on slopes and ditches. These expansive decks are rigid and won’t conform to the irregularities of the yard.

You will only create an uneven shave. In these spots, a small push mower or another compact mower would do the job well.
