Brain is going dead for sure....Help!

A standard old everyday double acting hydraulic cylinder for differing pieces of machinery; I'm going out to buy a couple and now I can't even remember what size to buy.

Can't remember the size (4" x 21" retracted)?, the size of the ram (1")? (1 1/4")? Eyelet size?

Geeze, this is pretty bad 'cause I've been around 'em since forever and just never paid any attention their size.

What size cylinders do you guys use?

Thanks,

Allan

Probably not anymore in this day and age; I'm finding everything is different! Enter: 4 wheel drive tractors, $40K pickups and goose-neck trailers. (but, this is a whole 'nother chapter)

Okay, so now I'm in the process of loading back up again and my mind is still stuck back in the eighties when I was forced to sell out.

Everything on the place used the same relative sized cylinders, from the corn head on the chopper to the lift cylinders on the discs & packers to the spin cylinders on the plows to the haying equipment. They were all pretty much the same size.

I think, as these other fellas have said, that what I want is the common "3x8" things.

But, what I won't have is a dag-gonned 4 wheel drive tractor!.....oooops sorry, wrong rant. :>)

Thanks all,

Allan
