if you don't have a grill gaurd on the front. there should be either a grill gaurd and/or front weight attachment holes. you could come off of. just make sure FEL(front end loader) still has room to move up and down.
on FEL arms. (without bucket or like attached) there should be a cross memember (pipe / tubing) something that connects the FEL arms together out in front. have seen folks use some hooks across it. or i don't know correct term UUUUUU has slots in it with some foam / rubber and ya hang them on your wall for fishing pools and other hand tools. but attached to the one area on FEL arms. with an extra bunjie strap or 2. to hold some shovels.
duffel bag with extra pockets for cab tractors can be a nice way to toss something into the cab, on the floor some place possibly, or perhaps behind seat if room.

i have had plastic tool box just completely shatter on me. and i have also had cheap very thin metal tool box's just bend out of shape. and will not close correctly.
ammo boxes, seem to be the more favored here on TBN. both with how lid closes, but also the latch.
for regular tool boxes...
some sort of "dog leash clip" put in paddle lock place on box is suggested. to easy to get into something and have top open up or from simple vibration, and have had latches come undo on me. trying to use a small piece of wire to just a paddle lock itself are rather painful to use. short dog leash has a rope already on it, that you can attach some place. and keep the clip easily assessable as ya get one hand loaded with tools / digging around.

would advise staying away from any "frame work" that holds glass as a place to attach a tool box / supports. if the frame work for glass just gets a tiny bit out of shape. your glass will break. and it doesn't take much.
