I found a red tool box similiar to the type attached to the fenders of old Ford tractors at Atwoods Monday; it is larger though, about 18x5x5 with a hasp.
I plan to mount it like Montyhp's; except I will space the SMV sign to rear of the tractor and locate the hasp forward or the hinge against the back of the SMV sign. I can not move the SMV to the right side of the tractor as that is where my rear aux quick connects are.
I'll post some pictures when I get it done.

I have an old ammo box I'm planning to bolt to the right-side step on my 4110. I can't enter from that side anyway with the foot throttle and loader stick in the way.
