i've got a great dane (meh), stander (pretty solid) and various other equip that i can just tell has a definitive shelf life, no matter how well i treat it. but every time i work on my exmark metro 21" push mower, i just think the damthing will last forever. it starts and sounds awesome and still cuts very well. its 6 yrs old and in mint condition (just with oil chgs etc). before i start to sound like an exmark rep, i'm just curious, what do you guys own that has just held up phenomenally well (without like an engine replacemtn, major rebuild, etc).
