A 4in1 is std here in OZ. It is rare to see a loader without one.
4in1 is a bit generiac a term as you often see them as a 6in1 or 8in1 as well
For the basic uses
1. Loader as per a normal bucket
2. Top dump, instead of tilting he bucket to dump the load you have the option of opening the clam. This is really usefull when spreading material like top soil or gravel. Just open the clam a bit (not all the way) and drive as the materiual comes out.
3. Grader. Open the clam and tilt the bucket forward. This enguages the clam blade and the bucket blade. Works the same as a box blade
4. Dozer. Open the clam and use the bucket blade as a dozer. Tilting back gives a good leveler as well. Tilting forward bites in
5. Scraper/Leveler. Open the clam and tilt forward enguaging the back of the clam. Traveling backwards you can scrape and level. This is also really hand when woring a pile being able to pull material down. This also gives you the top grab function
6. Top Grab. This is for the last of your pile. Do the same as the scraper but once you have material over the clam close the clam. This fills the bucket. Depending on your controls you may need to pulse the clam button. IE on my bx23s to clab I use the joystick to tilt the bucket while pressing the button. So when collecting the material I need to close the clam and tilt back athe same time. You get ysed to doing theis on the joystick whil pulsing the button.
6. Grapple Just open the clam, tilt over and close the calm. Works great for pulling stumps, posts and pickets as well.
7. Spreader/Smudge Bar This is an attachment you can grab with the bucket clam. Works as a grader/spreader. You just need to weld one up aout of some 2in RHS.
A lost of the ime I cant bother removing the BH, putting on the 3ph to attach the box blade when Im quicker and and easier with the bucket and spreader bar.Sometimes I use both the bucket and box blade though. I really only bother with the box blade if I need the rippers.
Here is a link to one in use
As for the bucket smile yu get theis with any bucket when its not used correctly. The quickest way to do this on a 4in1 is with the grapple. If you are grabbing a stump laying down t\you are using both sides of the bucket. Now do that pulling a post. If you use the center of the bucket you run a risk of bending it. Worse again if you tyy to rock it out or tilt it out. You have jsut crateated a bending bar. Its not a big issue to fix however. I just use a portapower and an I beam. Open the clam and suspend the I beam on chains from the clam. Use the portapower to push it back. Can yousuall fix it in under 30mins
That being said its far less of an issue that the stuff I see done with a conventional bucket. Some things many condiser normal on a farm would get you balsck listed at the mine. Liake back badeing and gardening both of which kill the cylinders and all of which are what the 4in1 is designed to do
Another great attachmant is a trailer hitch
Here is my one that I made

I can out the trailer hitch on in seconds and also tow from the sides of the bucket if and offset is needed
