Hi, hoping some of you can help me on this problem. My 190 Allis - on the "3-point", when I push the lever forward....should the arms drop? I thought they did years ago but not sure. The raise fine when I pull the lever back...but I have to "stand" on the arms with the lever forward to get them to drop. Please advise me....thanks !
 
As long as your weight gets them down it should be OK. Any implement will do the same. The only issue I recall is if the traction booster linkage, or valve, stick in a lift position.
 
Thanks! I can get by- just would like it to work; also the two levers on the right side of the seat...depth control? They haven't been used for 30 yrs- family tractor; do they control the arm height? Thanks.
 
The two levers are "position control" and "traction control".
As I recall, the levers should be full forward. As you pull the position control back, the lift arm travel/depth is limited. The traction booster lever works similarly, but responds only when a draft load is applied to the system.
The three point operating lever has a detent position just forward of hold for using the traction booster.
As stated, a problem can occur when linkage, or the little spool valve itself are stuck from lack of use/rust.
 
Traction Booster and Position Control levers need to be pushed clear DOWN for the hitch to go down. Last One-Ninety built was 1971.
 
Hey thanks...my fault ...I was guessing without looking...as I remember now I think my Uncle bought this new in about 68-69......I will check all this out....thanks!
 
mine has to sit outside and I have to lube everything up every now and then with penetrating oil. you may need to do the same.
 
Bob...can you find me a "trouble shooting schematic" on the lift arms...to help me figure this out? Thanks.
