I have a Ford LGT-145 with a three blade mowing deck, the problem is it came with out blades. Where do you guys get blades or what other brands will fit. The serial number tag is a sticker and most of it is unreadable. It is a Jacobsen and as close as I can guess the numbers are 57864T 076 they have been scratched out mostly. I would appreciate any help. Thanks.

I am on a similar quest. Mine has blades, but they are obviously the wrong ones - the peg holes don't line up with the pegs, and are a different size. The pegs are gone, so I ground notches in the shaft hubs to match the peg holes in the blades, and will secure with hardware.) So, it looks like I'm looking for the correct blades, and some new hubs. Will let you know what I find out.

Sorry, I haven't run across yet. Do you have any part numbers of the deck? Model number of tractor, etc.

Catdoo,
Thanks for the quick response on the 50" blades - I've been searching for days with no luck. Now I have another question for you. What is the name of those cast hubs on the ends of the mandrel shafts, with pegs to fit the blades? Mine have been rendered pegless, and I can't find any information, since Idon't even know what they are called. Do you think New Holland might have any?

I think the shaft is called a spindle and I'm pretty sure the "hub" on the end is all one piece.
Don't have a source, might try ebay.

Tractor is a 1968 Ford 100 with the 42" aluminum deck. Will have to pull deck Sunday night after I get home from the rodeo this weekend to get a part number.

Thanks to the forum members who've helped me in my quest. Through Amazon, I purchased 3 Oregon blades (91-203) @ $11.99, and from Jacobsen, and 3 blade adapters (the "hubs" I was looking for (336172)) @ 13.66, and all are now happily installed on the 50" deck of my LGT 145.
