No idea. Anyone know what this is?

It looks like a very heavy duty ground pulverizer

I'm sure you're right, Peter. Thank you!

Een CORONA virus---maar kan ook gebruikt worden om zuurstof in de grond te krijgen en de grond losser te maken

Ha Ha Ha, Fred!

Dat tweede (van mij ) komt toch in de buurt van Peter Castels mening !?

Yes, correct, Fred. Well done! But your first comment was what amused me!!!

What Jean says !

De toute façon il est original...Ça doit être un outil pour ameublir la terre.
Bonne soirée

Jean,
Colin,
Malik,
It seems I am the only one who doesn't know this thing!!!

Now I see it! It must have been used to break up old road surfaces prior to the laying of new roads.

Yes it does look like it was used to break up some sort of structure. If it was earth etc, then they would be pointy.

Thank you, Jenny!

In the United States, it is called a sheepsfoot. It is used to compact soil before pavement is added on top of the soil.

Why sheepsfoot, I wonder?
But helpful info nonetheless!
Thank you, Ronald.

I think it is because the spikes penetrate the soil as a sheep's foot would in mud.

Everything what I have to say about this is said ! Good Morning, Andy !

Pour ameublir un terrain ? Un casseur de revêtement ?

No idea ....

In the stony countryside of ours and by the times there was lots of "old paths" where people used to go on donkey, mule, horse back or these animals pulling a load. So these paths had to be levelled after the winter rains.
First with this tool, after with a smooth roller for damming up the soil.
They still do it in the Serra where I have the little house I show sometimes here.

Looks like you got your answer Andy! A heavy looking piece of equipment!

Well, it makes a great museum piece!

I've seen very similar machinery used for breaking up heavy ice on roads - but it seems a bit over-the-top for use in Spain. Same principle though!

Yes, but are they all yellow? All round the world?
Anyway there are mountains and much snow in winter, so maybe you could be on the right track, Keith!
