Newbie question:
How do the "innerds" of a 3ph work? What mechanism raises the lower link arms? Since there are no hydraulic cylinders visible outside, there must be the equivalent inside the tractor's gear case, right?
At first I thought that maybe the lifting mechanism was completely mechanical (e.g. eccentric cam and lever or something) but since there is clearly the sound of hydraulic relief valve operating at the top of the lift, it must be hydraulic. - meaning that there must be a hydraulic pump in there too.
Since my tractor is a gear type, I put gear oil into the transmission not hydraulic oil so I guess this 3ph hydraulic system uses gear oil not hydraulic oil.
I have no real reason to ask this other than I want to understand my tractor (Kubota B6100DT) better and there is nothing in my Kubota Operator's "Manual" about it at all.
Thanks
Bill
