We had an
L235 my dad bought used when I was a kid. Little brother to yours (same chassis but smaller 23.5 hp engine). It was an excellent tractor that seemed to run forever with just regular maintenance (fluids and filters) until my brother finally sold it to upgrade. It just sipped fuel too compared to the bigger hp newer Kubotas. As far as lack of power steering goes, I do recall it steered like a bear with a full bucket, especially if trying to turn uphill. I never looked into power steering for it, but hopefully someone with some knowledge in that area will chime in. Good luck!
