1949 cub, eratic hydraulics

ericlb · Aug 22, 2010

well i got my new/ old belly mower on my cub and all attached, still have to get the belt lined up right, but when i lift the mower, the front rockshaft will bob up and down about 3 inches while running, this is probably the heaviest impliment i have had on it since i bought the tractor, the tractor is refurbished, but had sat untouched after that in a mans garage for several years, if thats important, ive looked in the original owners manuel,as well as the service manuel i bought here, but it doesnt really say a lot about eratic operation by the hydraulics, or do cubs do this normaly? what do i need to do , or do i just need to get used to it, there should not be a problem mowing as the lift chain will allow the skids on the mower to just barely touch the ground and with the controle lever all the way to the lowered position it seems ok

Is the hydraulic oil full?

Oldiron29 · Aug 23, 2010

Eric, Like Tom said check you fluid! If full you have a problem with a leaking O ring in side the unit. TM tractor has the parts. I have had this on a 1950 and still have not pulled it apart for rebuild, one of theses days. Oldiron29
