I don't know why they went to a rear oil pickup ..my guess is safety. With my old machine when the hydraulic oil level gets a little low...you will lose everything when slowing or braking on a downhill...the pickup is at the bottom rear of the front case...so heading down steep hills it would suck air..very scarey as you cant steer, lift or stop... Newer ones draw oil from the front of the rear case. So you always have stopping and steering ability heading down hill.. If your oil level is low it will suck air when trying to climb a steep hill whereas the old machine would clomb anything with low oil level but then you wouldn't be able to get back down safely.
As for why they went from pushing oil through the rear drive motor first and then to the font then back to the pump.... 2 running oil through the front motor first then the rear then back to the pump... Again I can only guess....but right before they made the change they experienced a lot of rear motor failures... So by changing direction of flow it a little of the load off the rear motor and place it on the front which had not been failing... This was a stupid mistake my newer machine didn't have half the traction of the old 1... it got stuck easily and constantly spun the front tires when climbing hills. Steiner realized they made a mistake and returned the oil flow to the original way pump- rear motor- front motor- pump.lucky me happened to buy one from the 3 yrs they ran oil backwards.Forward traction is terrible compared to the original setup..as the front axle gets the majority of the torque and its much lighter than the rear when climbing steep hills or pulling.i ran it like that for years and finally had enough and replumbed it like my old one using new hoses....problem solved.now it feels planted to the ground just like my old Steiner.
