I can tell u what we did on three a 4020 powershift a 4010 synchro and 3020 powershift, took the battery boxes off and remade them to put group 31 batteries inside still fit where the originals go, then changed the cables to have no more top or side post problems. Put eyelets on the cables and put them on the bolt with a wing nut and stopped 80 percent of john starting issues, they are still hard on starters but nowhere that they were before.

You can isolate the hydraulic issue stuff by either installing a destroker and check the difference.
With hydraulic issues, the motor is ususally even harder to start hot and will not restart after stall. At least that is how bad my 69 4020 15000 hours without rebuilt is...
