Driveshaft driven hydros are much easier and WAY more efficient. Yup, a bit more technical as far as shafting and linkage go but do-able.
In the case of 2 hydraulic motors where the exaust from one drives the other...DREAMING! They are not pumps and motors at the same time ESPECIALLY ger-rotor types like the Case units use.
You need a hydraulic flow balancer unit and twice the hydraulic oil volume to do this correctly. Its $$ exspencive as hell too. With twice the volume you need more power as well and more oil storage to compensate the increased volume.
