Differential Locks

KIP in MX · Oct 13, 2011

Just wondering which tractors of each manufacturer were first with factory differential locks. I've only been around it on JD2020 and 4320.

Can't tell you who was first. Ford got it in the spring of 65 if that helps.

The xx10 JDs had it in 1961.

The 10 series JD would have been pre 1965

The xx10 Deeres had diff lock? New to me. My 4010 sorely lacks one, my 4020 has one, I always thought that was one of the upgrades from to xx10 to the xx20 series

I know this isn't along the lines of your question but many of the real early gas tractors and also steam engines have a differential lock.

Not quite as handy as a lever or pedal like came about in the 60's. The old stuff have a "arm" on the axle, you put a pin in the hole in that axle and it tied the two wheels together.

The Fordson Dexta has one. I can"t remember if it"s a 1961 or "62.

Dextas came out in 1957.

Dexta's had differential locks from November 1961.

Here in the UK IH introduced the diff lock on the B250 tractor in 1955. I have serial number 549 wice is the 49th one built because IH started all serial numbers at 501. MJ
