Kubotas all use "open center" type hydraulics, meaning the tractor supplies a constant pressurized flow of fluid to all hydraulic circuits whenever the tractor is running, whether it is in motion or not. When no hydraulic controls are activated, the fluid simply circulates through the supply lines and returns to the reservoir. In contrast, "closed center" circuits systems (such as used on John Deere tractors), are under pressure but there is no fluid flow until the control is activated.
I don't know enough about hydraulics to know if you can easily turn a circulating, open center system into an "on demand" one. If it ends up needing a constant feed of hydraulic fluid at, say 10 gpm and 2,500 psi, that could be a major energy draw and a challenge to how much battery storage you would need. If you were doing a backhoe project, for example, you might need to be working the tractor non-stop for 6-8 hours.
Maybe others have ideas about this. Repeating myself, I'm no expert.
B26 is maybe not the ideal starting point since almost everything on it is hydraulic. This does sound like an interesting project - as long as you don't need a working tractor in two weeks!
Good luck!
