Thanks guys for the info. The seller emailed me back finally stating that the hoe stands 9 feet tall as seen in the picture. I think the 445, 545 or 555 may be correct. I was thinking of getting this for my tractor but it is wayyyyy too big for my little machine. I should have know the yellow color was industrial use. For $650.00 it would have been a steal if it was small enough.
NO.
It's either a 713 or 723 hoe. Each hoe came in 3 flavors. 10, 12 and 14' depth. That one is either a 12 or 14' hoe. I am pretty sure it is a 14'er if it is indeed 9' tall. That would make it a model 19-301. If you measure the boom from the swing post to the end, a 14' unit will be about 9' 8" long. It would weigh in about 2600 pounds without the bucket. If it has been plated up, it could be over 3000 pounds. The "FORD" should be in script and not block lettering.
They are very powerful hoe's. The 14' unit has 8000# digging force with the boom only. (that's a lot). They can take a 30" high capacity bucket that holds 10.6 cu ft, but most often are found with 18" or 24" buckets. They made bell hole or grave buckets too, and were popular in graveyards. Units from cemeteries are desirable as they weren't abused and damaged. Lift to load height is about 1500# for the 10', 2000# for the 12' and 2550" for the 14'. Hydraulic pump capacity requirements varied from 16 to 23 gpm. Pressure was 2000 psi. The 14' unit operates best at the 23 gpm, but honestly lift times are still slow with the 4" cylinder for boom and dipper.
The original design was by Wain Roy and was bought by Ford and turned into the 713 hoe. It was made from the mid-late 50's to about '60. The 723 was an improved model with some changes to the hydraulic cylinders mostly. At some point, I think still with the 713 series, the swing post was changed to a more robust design with a much larger horizontal pin. 1.5" going to 1 7/8"
Biggest knock on the units was (and is) the boom tends to drop extremely fast. It can be modulated, but a very light touch is needed. The 4 stick controls are also non-standard and some say bass-ackwards.
I don't know how big your tractor is but you would want to be about 10,000# for the loader, hoe, tractor and weights. Ford recommended 1200# of filled tires and 1400# wheel weights.
Any more detail needed? ;-)
