Rear Blade Dozer blade/polisher

Thanks for your reply, I had kind of suspected the difference in countries might be the reason for the different words.
Whatever you choose to buy I hope it winds up working great.

I know it *says* it's 15mm thick, but

I can't quite believe it. I'd go with 10mm max.

The unit which states it's for 18-25HP is 1.2m wide (4') and weighs 70kg. Super light.

Shows 1.2-1.8 for a guide on my HP, the picture was used for reference only.....

The 1.8 is 84kg, which tells me that the increase is almost all in the blade and not the rest of the structure.
I suppose if you're polishing already-loose dirt it may work. I think if you were using it and it caught on a root or mostly-buried rock it would bend.

There's also a 1.8 (ESPOL2550Z) which is 240kg, which honestly doesn't sound heavy-duty either, but it's at least normal-light-duty.

Here's what a better rear braced rear blade looks like. It also has offset and angle.

Yep, found a heavy one that articulates in two places, Italian made, looks as though the heavy ones even bend....

Here is what I did to my cheap blade after it started to bow.

My first rear blade - Land Pride - on my first tractor - Ford 1700 - was just to light to do any real dirt work. It weighed around 300 pounds. It was great for snow removal.

In 2009 I upgraded to a brand new Kubota M6040. I got a Rhino 950 rear blade. Eight feet and 1050 pounds. This one does some real dirt work.

I had a Kubota BX with a 5 foot wide blade and now have a John Deere 2025r with a 6 foot blade. The 5 foot blade on the BX was sturdy enough but the tractor and blade were to light to do much serious work. The 7 foot blade on the JD works much better just because if the extra weight of the blade and tractor.

Three considerations if the OP's question is how do they work:

A heavier weighted back blade is more efficient for working dirt than a lighter one. There is typically no down pressure applied by a 3 point hitch, so increasing the weight of the implement is critical for ground engagement. You might find ways to add weight after the fact, but that can negatively affect a lighter built implement.

Depending on the intended use, being able to angle the main beam side to side at the 3 point hitch end adds considerably to the tool's functionality.

Third point is sizing the blade to your tractor. Generally, people recommend going as large and heavy as possible based on your tractor specs. A too large and heavy of a blade loaded with spoils can stop your movement if it exceeds the weight and power of your tractor. An undersized blade is better used as a garden decoration or boat anchor.
