cutting bad what is this piece callled

Fatdaddy · Apr 8, 2018

Couple of years ago my ZD326 was cutting bad bauging down.... took it in the guy said it needed a piece on one of the spindles..
he put it on and it did fine.... Now its doing it again and I am putting new blades on... this pic is what he put on goes on right above the nut..

I will need to go ahead and get me 3 more of them...

Can you tell me what they are called and what its doing???

Called blade adapter. Need one for each spindle. Blade will be mounted on this adapter.

did this not come on the mower to start with?? He added this after my mower would cut bad..
what causes it to need it??

So this goes on BEFORE I put ON THE BLADE???? i was going to put on the blade and then put this with nut other big washer??

thank you for the reply on this

They wear out and then the blade is not held tight and slips so you get a bad cut cause the blade is not spinning at full speed.

So does this go ABOVE the blade or Below the blade when I put it on???

The guy did not replace on he added it to the spindle..

Usually you go
spindle
Blade adapter
Blade
Cupped / flat washers
Split washer
Nut

The blade adapter usually has a raised section that is the same diameter as the hole in the blade but not as tall s the blade is thick.
The blade goes over the adapter then a heavy flat washer goes on the blade followed by a cupped washer.
When the nut it tightened these clamp the blade.
As such the blade spins but if it hits some thing really solid the blade can slip so it does not break or bend.

I don't think Kubota used the exact same spindle arangement twice.

I will need a picture of the spindle it was on and the other blade spindle to give any more advice.
It could be who ever repaired the mower use an old worn out adapter to replace the cupped or flat washer to clamp the blade.

That particular style of adapter was used on spindle that has splines on it which of course engage with the splines on the adapter.
If your spindle does not have splines then the repairer use it as a spacer or clamping washer.

Look at THIS CUPS !!

One guy told me it was the bottom of a cup... Look at these cups 1 has washer one not so much one has nothing..
How do you get the CUP OFF?? It don't move seems real tight.. No you tube on how to remove them..

Look at that first pic... like the cup is one whole bug piece see the groves around the cup?? I know take the nut off top spindle and it slides out....
do those 4 nuts on top take the whole cup off???

The 4 nuts allow the spindle housing to come off the deck. In the diagram I posted the cups have nothing holding them on except the blade. If I was you I would be taking the spindle housing off and looking for everthing to be in place and not broken.

And going to the dealer and seeing what those cups look like to see if you need to replace yours.
