With the blade width question you have opened (possibly unwittingly) a huge kettle of fish.
First, most bandsaw manufacturers state the upper blade capacity width on the widest blade possible to snake onto the wheels and the guides can handle. Often the very largest blade a saw "says" it can take is a pain to actually get on and off the saw depending on the path it must take. That said I would expect the 3/4" width maximum to be conservative on a saw like this and will probably go on without much trouble, but that remains to be seen.
The second issue is what width blade can a particular saw tension properly, since it matters not if you can physically put on and track a 2" blade, for example, is the saw can't tension it properly for use. Further, a blade is not a two dimensional object so the thickness of the blade is also as important as the width when it comes to how much tension a saw can put on the blade since area is what is important with strain, not width alone. So a saw may provide adequate tension for a 3/4" x .025" blade but not be able to tension a 3/4" x .035" blade since the cross section is roughly 40% greater and therefore needs roughly 40% more spring pressure to reach the same tension as the .025" gauge blade. This is compounded further by the fact some blade require more tension to be optimized, a carbide tipped blade will most likely be beat at 25,000-30,000 psi of tension where a carbon blade will work the best at around 15,000 psi of tension. So a 3/4" x .035" carbide blade will need a LOT more spring pressure and thus frame rigidity compared to a 3/4" x .022" carbon blade since the spring pressure will need to be nearly double to tension the cabide blade.
So to answer your question you need to know how practical it is to mount and dismount a 3/4" blade on the saw and then if it can tension a specific 3/4" blade. manufacturers of hobby to light industrial saws do not provide this information, it has to be determined by measuring a saw or using it and getting and educated guess by experience. My guess is this saw will work fine with all carbon blades and all but the thickest bi-metal and carbide tipped blades, but it is good practice to avoid the thickest bi-metal and carbide blades on 14" saws. With Grizzly saws like all the other manufactures you really have to take a hard look at the saw and tension spring area to get a guess. The 14" Delta cast clone saws from most every manufacturer list a 3/4" blade max, while you can usually get it on and off even a thinner gauge carbon steel blade is going to be under-tensioned on every one I have ever measured, this includes ones with aftermarket higher spring rate springs (which one must be careful with). Just looking at what I can see of the specs and in the pictures I expect this saw to be able to tension the thinner carbide and bi-metal blades properly, whether it can on the mid-thickness ones is a question but I would avoid those on a 14" wheel in any case.
