John Deere Plows Revisited

Pulled two plows out from the back machine shed that were used in my high school years. 1970s
But have a question. They look identical but the numbers are different. Can anyone tell
me what the difference is between a F-145-H and an E-145-A .They were used behind a
4020 and a 3020. Both 4 bottom 16 inch but one was reduced to 3 bottom 16 inch.

They are the same plows with one difference.I think that the plow with the E will have three bolts that hold the trip assembly to the plow while the F plow uses four bolts.The F plow more than likely has no serial number plate only a decal while the E plow will have a metal serial number plate. Some later F plows had a serial number plate. Tom

May I ask why there is no E 145 plow listed in parts catalog search on JD's parts website? Plus I've never heard of an E 145 model plow before now. I was thinking difference between A(regular hitch) & model H was H had hyd landing while model A was manual landing.

I think that Deere just changed the way they numbered them on the serial number tag. Lots of implements had an E serial number on the tag but not in the model number.Often it was EO then serial number. Tom

Dad has an f-145 and I think it has a metal tag on main beam...ill look tonight.

The "E" mentioned was used on most all implements of that vintage by Deere. It stood for "Equipment". What followed many times had absolutely nothing to do with the model number of the implement but was known as a "type". For instance, look at a BWA disk. The serial number plate will say "EO"-something with numbers afterward. The only way to decipher this code was to look in the parts book or service manual. This being said, there is no "E145" plow. There are the F145H or the F145A. The differences are mentioned with the "A" being the later plow. The mounting bolts on the standards to the frame are smaller and fewer on the later "A" plow, otherwise they are very similar. Deere also used a similar code on their engines during this time span. The engines (tractor, combine, etc.) start with "M" (for motor) with a numerical code afterward that means nothing (again) unless you have the key (in the books) for this. This makes life difficult for parts people (of which I used to be). Once you know the code it's not to hard to recognize but the model number is not necessarily what is on the serial tag if it has an "E" or something like that on it. Mike
