The Gravely Timeline Thread
 
I've heard the occasional rumble about creating a Gravely timeline, but if there is one I don't know about it. So assuming that there is none, how about we create one right here in this thread? If someone has something to add they can just post and add it, and maybe we will end up with something we can output in timeline form. :)

How it would work is if you had something to add, you just copy/paste the list from the previous post and modify it with your addition. For now we'd be just making a list, just try to insert your addition into the part of the list it should go chronologically. We can clean it up as we go. Info doesn't need to be added in order, if you know something, add it in! Just make sure to keep the list in a separate block form your comments. Let's just dive in and we can discuss particulars as we go. :)

Let's do this! I'll start with what very little I know:

"1922: The Gravely company was incorporated"

I put together a list of design changes on the two wheeler. You could add that to the timeline. Early model L changes are pointless. BFG would walk the assembly floor and make ad hoc changes almost daily. It was so bad that after a while the President of the company forbade him from walking the floor. The fellows assembling tractors would see him coming and alert the front office. Then someone would usher him out.

Is this how he lost the company?

Nah. He didn't lose it. As far as I know BFG was out of the picture when Studebaker bought Gravely. Then came Clarke Equipment, etc.

I think BF Gravely was forced into retirement in the 50's, was it D Ray Hall that took over? I think B F Gravely had passed away by the time studebaker took over. I'm trying to remember some facts that I read in a Gravely Gazette years back.

1960 the Gravely Tractor Company was bought by Studebaker corporation for $12.5 million

BFG gone by then.

I really want to see this!

I bugged Fla Don, but he was too busy. We are all too busy and a lot of info will be lost.

Yeah, yeah, I know. Things are finally starting to slow down a bit. The gun shop closed up last month so now I will be spending more time at home. Just depends on which home I'm at how much will get done.

Re: The Gravely Timeline Thread
 
I'm going to tentatively add some stuff from my thread on my new '62 L, subject to correction. And a few things I'd like to see dates for. :) Perhaps Roger can add in info on bearing caps?

19? L models changed from oil bath to dry element air cleaners

19? L models changes fro the "regal" or "sunrise" red color scheme to "chevy engine orange" and off white
19? "Chevy engine orange" changed over to "Mustang" orange. (add other names)
19? L models were equipped with high pressure oiling systems
19? L models went from exhaust cams with a protruding end to one that was flush with the engine case
19? L models switched from spring style valve covers to the style with covers (also info on the 2 types with covers?)

Here's some educated guesses, based some machines in my own family.

19? L models changed from oil bath to dry element air cleaners - 1962-63 ?

19? L models changed from cast iron rear facing to aluminum bodied front facing carbs.
Dad bought an LI new in 1961 from J.P. Fuller in Annapolis, MD. It has a rear-facing aluminum Zenith carb, with the long "wrap-around hose" to the air-cleaner ( oil-bath ).
I have a 1963 Custom L-8 with a front-facing Aluminum Zenith.


19? L models changes fro the "regal" or "sunrise" red color scheme to "chevy engine orange" and off white - 1962-63 ? Probably when they introduced the new sheet-metal.

19? "Chevy engine orange" changed over to "Mustang" orange. (add other names)

19? L models were equipped with high pressure oiling systems - 1958 (according to service manual ?)

19? L models went from exhaust cams with a protruding end to one that was flush with the engine case - do you mean intake-cam ? (Exhaust cam drives the mag...) Probably 1958.

19? L models switched from spring style valve covers to the style with covers (also info on the 2 types with covers?) - 1958, with the switch to high-pressure oiling.

The service manual I refer to is the one Dad got for his 1961 LI...

My father's LI, purchased new in 1961, has a REAR-FACING aluminum Zenith, with the long moulded rubber tube from the air-cleaner, with the U-turn to the carb air-horn. (Essentially a rubber version of the earlier metal-flex tube with the cast U-turn). This machine also came with a governor, and old-style "rod-type" throttle control.

Dad's LI is Serial # M 61914 Mfg. # 12416, built in 1960, according to the PDF attachment.

I do know that it came that way from Gravely, and was never modified.

This machine also has the slotted fan housing


I'll try to grab some serial info from my other tractors...

Gravely Frank McM 06-09-2015 02:39 PM

Re: The Gravely Timeline Thread
 
Found some more info...

From Gravely L-8 "Super", Serial # 2 M 3968, Mfg. # G 13634, built 1963. (Like the one in my avatar :fing32: )

> Front-facing aluminum Carb, w/ short moulded rubber tube to air-cleaner

> Dry element air-cleaner ( pleated paper ) in white tin housing with black silk-screen / indicia.

> Orange and white

> Starter

> No Governor, old-style throttle lever and rod

> dual wheels

> remote PTO control (loop-handle)
