Got a lot of experience operating tractors but don't own one myself. Most of my experience comes from working on farms and my summer jobs.
As per my bias I'm really a John Deere fan for bigger stuff but at work we have a Kubota BX24. The thing has over 1500 hours of hard labour(working in very hard terrain where our bigger stuff cant go) done on it and for the most part has only needed general maintenance.
But my baby at work is a Kubota MX 5000(thats not mine pictured)
