Help w/ Kubota RC44G Belly Mower

[kajun]

Unit mates to Kubota G4200 but I suspect my question is common to many mowers including modern Kubota Z Turns . Unit has three spindles [ two outboard and one center ].

Outboard spindles have center bolts and each also has two-little-male-projections that engage the blades . Center spindle lacks the little male projections. The male projections are obviously needed to prevent free spinning of these high speed blades.

This is a new to me mower and thus my first time to disassemble. I have looked at the parts schematic and I fail to see part for center spindle with male projections that matches to outboard spindles . Am I missing something ?

Obliged for any help.

Well my friends,

Kept looking and found my answer right on OTT in a post by BruceP on 12-27-16. I re-post Bruce's comment in case someone later wishes to know answer. Said Bruce:



"The bolt [ on the center spindle ] is VERY special with a double-shoulder to compress two Belleville washers against the blade so I have to source replacement from Kubota.

I do not want to be messing with the design which allows for the center-blade to slip if it hits something. After-all, this center blade is driven DIRECTLY from the right-angle gearbox and has no other means of 'safety'.

The outer two blades are belt-driven and do not use this special type of bolt. They are essentially lock-washered against the blade."

So thanks , Bruce and best to all .

I have the 48 inch version of that deck. All three of the spindles take double cup washers that hold tension on the blades. Mine goes on a g6200h. Great tractors except parts are getting really hard to find.

Kubotabooks.com in the Mowers section has a 3 part WSM for the RC44 mower decks.

I found one section specifically dealing with the RC44G.

It shows different arrangements for the outer and center blades.

The bolts are different, the torque values are different and the center blade does not use cupped washers.

This is a first for me!!
