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...
It would be great to get a handle on just what happened in the changeover from iron to aluminum carbs.

Gravelys: 1951 L, 1952 L, 1954 L, 1956 LI, 1961 LI-SR, 1962 L, 1962 LI, 1963 LI, 1965 L8, 1965 LS, C 10, 524, 5460, 8102.

I can quit any time I want. I just don't want to right now.

The rest: 1969 WH Raider 12, 1983 WH A-111, 1985 WH 314A, AC 917H, 1978 Ford 2600, 1978 Ford 4100, 1975 Ford 3550 Industrial, 1959 Farmall 560, 1949 Case VAC, 1951 Case VAC Eagle Hitch, Troy Bilt Horse, Troy Bilt Pony. Mowers, rakes, balers, and far too much other old junk to list....

Re: The Gravely Timeline Thread

We are missing something sorting big, when did gravely introduce the first two wheel tractor?

We all know the first two wheel machine is commonly known as the hex axel L, It was produced in 1930 what? Then when did the first true L come about?

Also from what I understand some early L's had an aluminum head, when did this start/stop?

I have an old Gazette at the house that has a nice write up about the L, I'm away on vacation till the 18, when I get home I'll do some digging.

Re: The Gravely Timeline Thread

I wouldn't mind knowing when the Bosch starters were introduced. My 63 came with one and I ended up buying another for my 73. My 63 was picked over pretty good when I got it so I'm not sure if the Bosch is original.

Re: The Gravely Timeline Thread

I have three L's from the mid-1960's,('63,'64,'64 ) two Supers and one Custom, all have Delco 12-volt starters, and I believe they are original to the machines.

Re: The Gravely Timeline Thread

I know the original starters were 6 volt Autolite (early) or Delco (later). I know the change to 12 volt happened in the early to mid 60s. My neighbor has a '63 and a '64 with electric start. The '63 is 6 volt and the '64 is 12 volt. Both starters are original. Not sure if the 6v is just a leftover that Gravely used, or if they were still used on all tractors in '63. I'm assuming the change happened in late '63 or early '64.

Re: The Gravely Timeline Thread

Based on the 63 manual it has the forward facing carb. I read on here somewhere it was short lived. I don't know if the 62 had it or not or how short lived it was. I was confident enough in the poster that I got one for my 63.

Re: The Gravely Timeline Thread

Ralph has a 57 with the autolite starter. At least it's a date even if it isn't the transition year.

Re: The Gravely Timeline Thread

"1961-2-3? L models changed from cast iron rear facing to aluminum bodied front facing carbs. Was there a year with rear facing aluminum? Needs further narrowing"

Yes. There was at least one year with rear-facing aluminum.

My father bought a new LI in 1961 from the Gravely agency on Defense Highway in Annapolis. It has a "Zenith-Bendix" rear-facing aluminum carb.

It has the long, moulded rubber wrap-around hose from the air-cleaner to the carb.

Its numbers are as follows:

Serial # M 61914 Mfg. # 12416

The Gravely serial number pdf from the Stickies puts this machine as a 1960.

This machine also has a governor. Don't know if this feature was factory or dealer-installed.

Dad bought this machine new in 1961, and I came along in 1967. I began cutting grass with it around 1972 ( Dad would start it for me, I would mow the grass and hopefully not stall it ! )

Dad never replaced any parts on the machine, except the gas-tank, which tended to crack around the square bung-reinforcement.

I still have the machine.

Further clarification: Red & Black, with "old-style" brake-bent hood, tin shields on top and sides of cylinder, slotted fan intake, four-blade fan, Wico X magneto, Full-pressure oiling with spin-on filter and gauge.

Re: The Gravely Timeline Thread

I have a '57 with a non-protruding intake cam, so it didn't change in '58. I would guess '55, because I have seen '56 tractors with non-protruding intake cams.
