[AT] Case 411 lpg tractor

[Bustedtractor at aol.com]

I hope I am not to late to respond to your question. My dad had a 1957 Case 
411B gas tractor and it was not very reliable. We had multiple problems with 
the hydraulic system. The lift cylinder for the 3-point became scored and the 
fluid would leak into the Case-o-Matic transmission. (I am assuming that the 411 
you are talking about has Case-o-Matic?) I carried a 5-gallon bucket with in 
the field and would drain hydraulic fluid from the transmission and pour it 
into the hydraulic reservoir every 2 hours. A number of repairs were tried and 
we finally had to replace the entire 3-point lift package to solve the problem.

It had a hydraulic clutch which defied adjustment and you could never shift 
into gear without grinding. The support brackets for the 3-point lift arms 
broke as they were underdesigned. Dad fabricated replacements that were much 
stronger to correct that problem. The upper arm that the hitch swung on broke and 
needed to be rewelded. The transmission gears did not stand up very well as I 
observed when we pulled the shift assembly off the transmission for a repair. 
Some of the gears were worn to sharp points when they should have been flat on 
top. We did not abuse the tractor. It did not seem to be well designed.

Two years ago, my younger brother asked if our 411B had any distinguishing 
marks that would identify it. He asked because a friend of his thought he may 
have bought it. I gave him 4 items to look for and it was positively identified 
as the one my dad had traded in about 40 years earlier. I had the opportunity 
to drive it in a parade at our show that year (LRPTA in Dalton, MN). I 
immediately remembered why I didn't like that particular tractor.

I hope this information is useful!
