Great advice above.
I opted for the longer forks on my machine. (IIRC the weight difference was only 25 lbs'ish)
My dealer suggested the shorter forks cause he said "You can damage the thing behind the load your moving if they stick too far out."
Now if I was in a "dishwasher" warehouse facility, then I suppose that makes sense.....but I am not.
My reasoning was that I wanted my forks to stick out a "wee bit" as sort of a "safety factor" when moving a "standard sized" pallet (whatever that is) so it doesn't "slip off the end".
I dunno.......6 of one, half a dozen of the other, I suppose.
Either way, I love having forks, and use them regularly.
