ATCO B24 - Blade removal

Enter a word or two to search the forum section and click the Search Forum button.

I have 3 wonderful old lawn mowers. The thing is when they breakdown I just buy another, shame on you I hear you cry! Well I have now started fixing an old Atco B24. I believe it may be the heavy duty model.

It was a sorry condition when I saved it from the scrap man but I fixed the engine (Honda GX 140) and spent a good deal of time roaming around my patch, not cutting anything, just making it flat.

The bottom blade was horrid, so I got a new one.......only to find the screws had been spot welded. Some time later and a new file I got it replaced. So now it cuts a bit.

But the grass deflector was rotted. I got the engineer at work to fix that and he welded on a new piece.

Off I went again, up and down creating tiny crop circles.

Took the whole mower to the local lawn mower shop to find that one of the blades had cracked and was not worth re-grinding (Not safe he said)

But now I have a reconditioned blade and want to get the old girl up and running.

Can anybody tell me how to change the Blade Cylinder. Looks like a big job. I guess i have to remove all the chains etc or even take off a side?

I have removed the bottom blade and grass defector.

When you say 'blade cylinder' do you mean 'how do I remove the cutting cylinder' ?

To remove the cylinder, you need to remove the chain cover, then the chains to the cylinder, remove the sprocket assembly from the end of the cylinder. Remove the delivery plate and then the bottom block assembly. You should then find the cylinder is retained by three bolts at the non drive  and three bolts and nuts at the drive end, remove these and the cylinder should drop out of the frame. You will need to lever off the bearings (or use a puller), but watch out for the washers and shims behind the bearings.

To put it all back together again, just do the above in reverse.

What is actually wrong with the cylinder, you can weld them if needed, I have even built up broken blade ends.

As our learned colleagues have said it is normal practice to weld up cracked or broken blades but it should be noted that after welding the cylinder will need to be re ground back to true.
