Welcome to TBN
1st thing I'd suggest to do is check hyd system pressure. With that number of leaks it sounds as if hyd pressure is too high. Kubota LA1301 loader spool valve schematics lists a spool seal o-ring kit.

Something is very screwey. Sounds to me like your hydraulic pressure is way too high. Two of the loader cylinders on one of my M9's weep slightly but the tractor has over 6000 hours on it and a lot of loader work moving and loading round bales. If it gets worse I'll probably pull them and take them to a local hydraulic shop to get rebuilt but none of my valving leaks at all which leads me to believe you pressure is way too high.

Not uncommon with my 30 years of ownership Have 4 Kubotas and I have seen over the last 2 decades of using them in farming & mowing that Kubota uses seals that develop leaks earlier on than my other brands of tractors & equipment.
I have developed several seal failures over the years. In fact, it’s the most common issue I have with their brand.
Your case sounds different. Are you the original owner? Any chance a previous owner fiddled with pump/pressures?

Sounds like it might be highly restricted / dead headed. Pressure has to go somewhere.

Deadheaded hyd pressure should not cause FEL cylinders to leak unless FEL control valve is the reason for the deadheaded oil
