Husqvarna RZ4619

The Husqvarna RZ4619 zero turn lawn mower is not the best known machine as it is quite similar to both the Husqvarna RZ4623 and the Husqvarna RZ4621 zero turn lawn mowers. All 3 lawnmowers have the same 46 inch mower deck, however the RZ 4619 is the least powerful machine of the 3 machines. The engine that powers the wheels and the mower deck on the RZ4619 is a Professional Series from Briggs and Stratton. This engine uses a standard type air filter to cleanse the air intake of small particles which have the potential to clog the combustion chambers and disrupt the combustion process. The engine is key started using a 12 volt battery. Once the engine is running, a 16 amp alternator is used to recharge it.

The engine transfers power to the blades on the mower deck of the Husqvarna RZ4619 through a belt drive system which is engaged using an electric clutch. The 46 inch mower deck houses 2 blades. This deck cuts grass as low as 1.5 inches above the ground and as high as 4.5 inches above the ground over a 3 inch cutting range. The deck discharges the grass out the ride hand side as standard.

The engine also powers the wheels on the Husqvarna RZ4619. Specifically it powers only the rear wheels, which measure 18×8.5-8 (18 inch diameter, 8.5 inch width, 8 inch rim diameter). These rear wheels have a turf thread that handily grips the lawn as they travel over it, without the problem of potentially cutting it up if it’s wet or damp. The front wheels are smooth as these don’t need to grip the grass, they simply need to travel smoothly over the lawn and provide as little friction as possible so that the rear wheels can easily turn the RZ 4619 in different directions.

    My experience has been good except for the problem with the deck
    belt.

    Year of Manufacture: 2011
    Pros: This machine cut my mowing time with a tractor style mower in half.
    Cons: I’m having a time keeping the deck belt on. When I pull the electric
    switch to engage the deck the whole mower jumps and the belt comes
    off. I’m wondering if there’s a brake on the deck so it stops the blades
    as soon as the switch is turned off and perhaps that brakes is not being
    released when I pull up the switch to start the deck. If anyone has had a
    similar problem and has an idea about the cause please let me know.

    The belt frequently disengages. I cannot re-position the belt to engage the blades, so I frequently have return the mower for repair. Since I purchased the machine to mow grass, this makes the mower unacceptable.

    With 19.5 HP you cannot travel at top speed through extremely tall grass. If you mow every 7-10 days in the spring this will not be an issue.

    Year of Manufacture: 2009
    Pros: After 3 full cutting seasons I feel qualified to rate this machine. The most impressive aspect is it’s extremely economical operation, it’s amazing how much ground it will mow on a gallon of gasoline. The Briggs & Stratton has always started and performed flawlessly, it used a bit of oil the first day I used it in 2009, which I replenished before using it the second time, but it has not consumed any oil since. I Change the oil at the end of every season and the level is always still on “full”. I have used the recommended synthetic oil.
    Cons: If the cutting deck solidly contacts a wooden fence post at high speed the belt will jump off. This happened about 5 times before I figured out it was easier to just avoid contacting posts I have had no other mechanical issues with this machine. I deducted half a point on reliability for this trait.
    Modifications: None
