Problems with the Husqvarna YTH22V46

You may come across a variety of problems with your Husqvarna YTH22V46 lawn tractor. The most common issues are listed below:

  1. The engine continues to run when the operator leaves the seat while the attachment clutch is engaged. This can drain your battery and cause the engine to become hot.
  2. A poor cut, uneven cut and/or clumps of grass in the discharge spout are all signs that your mower blades are not sharp.
  3. Mower blades will not rotate despite the engine running at full power. This could be due to brake failure, or a stuck drive belt preventing proper rotation.
  4. Poor grass discharge can be caused by an accumulation of debris within your mower deck’s discharge opening due to clogged chute assembly or a damaged discharge chute door hinge or latch assembly.
  5. The battery will not charge due to loose terminals or corroded battery terminals that need to be cleaned before reconnecting them.
  6. Loss of drive 
  7. Headlights not working

Engine Continues to Run

In this situation, the engine continues to run when the operator leaves the seat with the attachment clutch engaged.

One reason may be, the attachment clutch is not disengaging when the operator leaves the seat. An intermittent contact may be present at the attachment clutch switch or wiring, or at the switch at the left rear of the operator’s seat. The wiring to this switch may be damaged or corroded, or an intermittent connection may be present. 

Another problem might be the presence control system wiring, switches and connections.

Check operator presence control switch, connection to tractor frame and tractor seat switch.

Check for an intermittent contact at the attachment clutch switch and at the switch located on the left rear of the seat. If an intermittent contact is found, repair it. Refer to circuit diagram for trouble location information.

Uneven Cut

The mower deck must be level and the mower blades must be all the way down to the ground. If either is not the case, uneven cuts will result.

If the mower deck is not level, shaggy or long grass may be a symptom of that problem and not necessarily a condition that leads to uneven cuts.

First determine if your mower deck is level and that all four blades are in contact with the ground when they are engaged. Use a straightedge across the front of the mower deck to verify that it is level. If it is not, raise or lower it as instructed in your operator’s manual.

The second step is to check the mowing blade engagement. Make sure all four blades are touching the ground when they are engaged in order to provide a flat surface for cutting grass.

Check inside of your mower’s housing for build-up of grass, leaves, and trash around mandrels that hold the blades in place. Remove this build-up by cleaning around mandrels with a stiff wire brush or compressed air to open vent holes.

The most common cause is a worn-out or damaged blade. The solution is to replace the blade if it’s not too badly worn, or replace the blade mandrel if it is bent. 

If you see that a large chunk of metal is missing from around one of the holes in which a mandrel fits, that mandrel needs to be replaced.

Remove obstruction from the clutch mechanism. Inspect clutch mechanism for any obstruction, such as grass clippings, leaves, or foreign material. Remove obstruction from the clutch mechanism.

Check the mower drive belt for wear and damage. Inspect mower drive belt for signs of wear and damage. Replace if necessary.

Inspect idler pulley for wear and damage. Inspect idler pulley for signs of wear and damage, such as cracks in the plastic pulley or rusting of the metal bracket holding the pulley onto the mandrel shaft. Replace if necessary.

Inspect blade mandrel for wear and damage. Inspect blade mandrel for signs of wear and damage, such as rusting or cracks in the mandrel housing or alignment of the mandrel to the blades themselves.

Check if they are properly aligned with each other to produce a smooth cutting action of the blades when engaged with the mower drive belts.

Poor grass discharge

One of the reasons for poor grass discharge is the engine speed being too slow and difficult to pull. To remedy the problem, adjust the throttle control to the fast position and mow at a slower speed.

If your mowing is done in wet conditions, your grass discharge may be poor. Always mow in dry conditions to avoid such issues.

If your deck is too high or not level, the blade will have a difficult time cutting it evenly. Level the deck to gain a proper cut.

The blade may be dull or bent. It’s also possible that the blade bolt may not be tightened enough. Make sure that the blade bolt is tight before operating the machine again. Replace the dull blade if necessary.

Perform a general inspection. Check all fasteners, belts and cables for tightness and wear. Replace missing or damaged parts before operating the mower. Adjust governor spring tension to maximum recommended settings as outlined in the Operator’s Manual.

Inspect drive belt for cuts, cracks and fraying; try to tighten belt; replace if necessary. Check air filter element or filter cartridge for damage or excessive buildup of grass clippings; clean or replace if necessary. 

Inspect under mower housing for buildup of grass, leaves and trash; clean away debris. Check for loose mandrel nuts on mower wheels; tighten as needed using a wrench to avoid over tightening hub.

Headlights are not working

If your headlights are not working, then check the following:

Check that the switch is ON or not. The headlights will not work with the switch in the OFF position. If the switch is in the ON position, check for a burned-out bulb(s) or lamp(s).

If only one bulb or lamp is burned out, replace it with a new bulb or lamp of the same type and wattage. If you have a dual headlight system, you may need to replace both bulbs or lamps if they are of different types and wattages.

Check all wiring and connections for damage, broken wires, and loose connections. Connections may be corroded due to underhood exposure to water, dirt, or chemicals used on your tractor during operation or maintenance. 

Check that all wire nuts are secure; if any appear loose, tighten them as necessary. Damaged wiring can cause a fire if it comes in contact with spark plugs, belts, engine parts, exhaust systems, and other hot surfaces in your engine compartment.

If you cannot find any problems with your wiring, check the fuses. If the fuses are blown out, replace them.

Battery will not charge

The most common cause of bad batteries is simply old age. If the battery has been in service for 3 years or more, it is possible that the life of the battery has expired. You can test the batteries by measuring the voltage of the batteries. 

A low voltage indicates a bad cell, which will require replacement. 

When working properly, a voltage regulator should maintain a constant output from the batteries even as the load decreases. If you have more than one regulator, it is best to check them all.

If you think that there may be a problem with the alternator, check the component first. Replace it if necessary.

Loss of drive

When the drive will not engage and the engine continues to run in freewheel, then loss of drive is most likely caused.

Check to make sure the freewheel control lever is in the engaged position. If it is in a disengaged position, turn it back. Check for debris on the steering plate. Clean debris from the steering plate, if necessary.

Check for a worn or damaged motion drive belt. Replace if necessary. Another problem might be, air is trapped in transmission during shipment or servicing. Purge transmission to solve this issue.

The axle key might be missing. Make sure that both axle keys are installed on each wheel.
