Widening disc

[Mallard1]

I have a old 5ft angle iron disc that is pretty similar to this

King Kutter Angle Frame Disc Harrow 5 1 2 ft Notched 16 16 G N YK | eBay

It is needing new bearings, housings and a blade or two this winter. I would really like to have a six foot disc. Is it possible to just add the spacers and new longer shafts and just add a blade to the end of each shaft? Thanks for the help?

Possible? Perhaps.

Advisable? I don't really think so, no.

Two reasons:

1. Expense of buying/making the necessary parts - the longer axles you could maybe make, the spacers and disk blades you'd have to buy.

2. That's a pretty light duty frame. I'd be worried about the extra side-loading from the increased length twisting the frame or bending the brackets that the axle bearings are mounted to.

OTOH, if you can kludge it together from pieces-parts you have laying around, I guess it couldn't hurt to try. If it folded up, you could just go buy the 6' disk you want.

In my opinion a Disc Harrow with 16" diameter pans is too light to mix soil that has any significant clods and will float over many plow furrows.

A Disc Harrow with 18" pans is marginal. Disc Harrows really work well only with 20" diameter and greater pans.

A PTO powered Rotary Tiller is much more effective than a Disc Harrow with 16" diameter pans.
