As for the 5570 I can not vouch for, but I do have it's older, smaller sibling,a 5530.
I would highly recommend it as a good utility tractor. I run out of weight,before i Run out of engine.
Have not had any problems with it. the loader with a grapple has been a game changer for moving brush and logs.
I highly recommend forks for it. i use them all the time to move material around. It won't pick up a complete pallet of concrete from the local hard ware store, but remove a layer and it is good to go.
As for the radiator screen and inter cooler screen;they are bolted to the tractor,and are hard to remove.(I just blow them out, with a long reach blow gun.) I plan on maybe modifying them when I change out the original battery.
I have had this tractor since 2010 and Do not know how i got along without it.
the only thin I would change would be the position of the steering wheel,but that is not really that bad either.
