Got a good deal on a used 54” deck (Z254) a while ago. Despite the extreme frustration this thing has caused me today, it was still worth what I paid for it.

So here is my problem.

Changing the blades. Super easy, user level maintenance. No training required.

Two out of three blades changed no problem.

The center mandrel axel and bolt that attaches the blade to the bottom of it seem to be stripped. No big deal. Go to the local dealer, just looking for the axel. It is a Mennonite ran shop here in mid-west Louisiana. Mennonites are know for a little higher pricing, but quality work, and reliable. I’m not from here, but my GF has strong ties and personal relationships with that community, so I am somewhat familiar with them. They offer good service, for example, will easily stay open after business hours to help you, but they do charge a fee which corresponds with that level of service. (/story time)

The 150 year old sage behind the counter advises me not just to replace the axle, but the entire mandrel assembly as it isn’t super expensive. Being the psychopathic paranoid POS that I am, I wanted to BTFO of there as this chick was clearly trying to take advantage of me. Thankfully my human self remained in control.

“How much is the entire assembly? I’m asking because if it isn’t that expensive, as you say, I may just buy two to have one on hand.”

“~33 dollars”

It was about half as much as I anticipated paying for just the axel alone, so I took it.

“I will take two”.

Made the transaction, no issues.

Get home, open one of the mandrels, it has the housing bolts to attach the assembly to the deck, but no bolts to attach the blade to the bottom of the assembly. A little frustrating, but workable. Just go to hardware store in the morning and grab some bolts that size.

Remove one of the useable blade attaching bolts from one of the OEM mandrels still useable on the mower. Go to local hardware store. Measure the OEM bolt, grab three bolts (I like to be redundant) that match that bolt size, measure each one of those bolts threads (I like to be sure) individually compared to the OEM bolt. They are all exact matches. I expect no issues what so ever.

Get back to the mower, one new mandrel installed on the center blade, two OEM dirty trusties still going strong on the out board blades.

Because I’m a paranoid POS and OCD, I use the OEM bolt that I took for measuring to replace the right blade I removed it from (OEM Mandrel). Worked perfectly. ****s and giggles, take out that bolt, replace it with one of the new bolts. Like a mother ****ing glove.

Here is the problem, the center blade, where I replaced the old mandrel with a new one, neither the old (OEM), nor new (Hardware store, exact replica), will bite the thread.

My boys, when I tell you I practiced patience today.....

This one bolt stopped me from doing anything. I could not get the old bolts, or the new ones to bite in the new mandrel.

The only thing I can think of is Husqvarna has a specific bull**** ass ~7.0001/16 thread (instead of 7/16) on its new mandrels just so you have to buy their specific bolt.

While if this is the case, which I imagine it is, I can get over that. This is normally how dealers rape people, and while we shouldn’t tolerate it, what can we do? It is expected. But then why didn’t the sage pitch me the new bolts.

I tried everything today.

Obviously a lot of my frustration is aimed at myself for spending an entire day on such an easy task and not being able to figure it out.

Anyone work with their mowers so intimately? Have any input?

I should commit sudoku to restore honor to my family?

I should choose 40W over 30W to drown in for my sins?

God damned today was a complete loss of time and emotion. I could have used it to practice patience, but that went out the window hours ago.

Gonna go try to take some better pics of the comet to cool off. Thanks for listening, even if you are not familiar with this task or have advice.

I’m lucky in that this is literally the worst thing I have going on in my life.
