Husqvarna rz4619 blades will not disengage - Husqvarna Garden

SOURCE: i have a husqvarna 172 ride-on lawnmower. Running

This unit probably has a safety switch built into it and it could be below the gas tank. If this switch isn't adjusted properly then it's designed to cut off the motor. I think you should concentrate on that before attempting anything else.

SOURCE: how to disengage or fix chain break on husqvarna

It sounds as though you have tried resetting the brake to no avail. If I were you any Monday through Friday at 1300 - 1500 I would be in my local Husky dealer (not Lowes). Someone familiar with the saw that can see and touch it. I suspect you will need parts once the problem is isolated, order them there and the diagnosis will probably be gratis. Factor in the shipping and handling fee and most dealer prices are competitive.

If you have more questions or need additional help please reply below and I will get back to you. Good Luck. HTH

SOURCE: husqvarna pto problem(?) disengaged blades to travel, would not engage after. Battery dead when checked after shutting off engine and wouldn't restart

Hi, first charge or replace the battery if necessary then check that the mower is charging the battery. The pto is probably fine but it needs battery voltage to engage. If the mower has stopped charging the battery may have had enough voltage to hold the pto in until you disengaged it but not enough to re engage it. Regards Phil.

SOURCE: On my 42in cut hydro. Husqvarna, The mower will not disengage until the speed is reduced to a low idle

Before you do anything else check to make sure the blades are engaged on thier seat ( the star) and the blade bolts are tight.
If you have an electric PTO this does not apply to you.
After confirming that your blades are tight check the operation of the PTO cable and the pivot bracket by lowering the deck all the way. Laying on the ground on the discharge side of the mower you will be able to look at the components and see and touch whats not moving freely as you engage and disengage the PTO lever. Look for a stiff PTO cable, stiff pivot bracket, missing return spring, broken spindle brackets and broken deck bracket welds.
Of course you should never work on any mechanical device while it is running.

SOURCE: why when engage the blades on RZ4619 Husqvarna the deck jumps up towards the bottom of mower body and then Vibrates real bad.

Sounds like a spindle bearing out
