Rusty Mouldboards

[Cab-over Pete]

Aye-up,

After many years of asking I’ve managed to buy one of my late Dads old ploughs back.

It’s a Kverneland LD8NR 3 12” furrow reversible. Dad used it behind his MF 290.

It’s in really good shape, being hardly used since a local farmer bought it from Dad, but it has been parked outside for maybe 20 years. All the wearing metal is rusty, which isn’t much of a problem for wings, discs etc, but the mouldboards are a bit of a bugger.

KV don’t supply the 38” boards any more. Apparently they are No. 8 boards, but they are all over 40” these days.

I would like to keep it as original as possible so is there any way to restore them? Don’t suggest dropping them into a few acres of sand. Whilst that may work in that field they’ll never scour once I get it home.

I’m wondering if there is some kind of process that they could be blasted and polished?

Cheers, Pete.

Clean them up as best you can with a wire brush in an angle grinder and I'm afraid after that it'll take a bit of ploughing to polish them up properly. Prepare for hardship. If you could plough up ley you'd clean the boards a lot quicker then permanent tillage land. Don't go near then with flap wheels or discs, if you mark or score the boards you'll have scrap metal. You could try using the acid the concrete boys use to clean the spatters off their trucks either. It will remove rust but you'd want to go plough straight away after using it or rub in grease.

A friend of mine bought a plough that hadn't been used in 15 yrs so boards were rusted bad he took a flap disc to them and surprisingly it worked. It's only ploughed maybe 10 acres since and they're getting better all the time

My first Kuhn plough I got was the same.i used flap wheels on a grinder and it worked well.if you get a bit of silver showing you can then get the plough into work and let the soil do the job

Find someone who is doing a ploughing marathon

 

[Cab-over Pete]

And let him jump off the tractor to scrape them off at the end of every run!!! I like your thinking!

There is no way a bit of sanding and then ploughing will work on our soils unless it’s bone dry, and then I think the plough would be too light to go in.

I’m thinking maybe an industrial process of some sort?

Hi Pete,
Find someone who wants 20+ acres of sandy stoney soil to plough or old gravel pit (unlikely scenario). Maybe Gadget has some you could do? The only thing I haven't tried in the past is shot blasting - that gets the rust off but would make them dull I would imagine. Ploughing abrasive soil is the best way to get a good shine after getting as much as you can off with 9" grinder and sanding discs. cheers

Flap disc then work to the finest grade paper in a rotary sander. Like they use for taking back body panels before painting.
I've done 2 5f rev ploughs in last 12 months. More like 2 years rust than 20 but they were too rusty to plough with.

Will rust soften with waste or penetrating oil?

Pete clean them up ,then bring it here ,and plough 25 acre or silt .it will have polished boards when finished

 

[Drillman]

Some heavy abrasive land would do it. A nice wet paddled headland.

Other option is to consult TFFs resident old plow expert............. oh hang on???

That was the one good thing with that ancholme Carr land,, it would put a mirrow polish on anything that went near it,, just had to catch it right, it was either concrete or cack
