So you've gotten lucky.
"Lesser" brands do not have much to do w anything as far as repair but if something goes wrong with any brand tractor, would you want a dealer with their thumbs up you know where or one that is fully knowledgeable and close by to be able to "support" the breakdown?
Also, the word "dealer support" does not only apply to repair.
Some bring their tractors in for hourly servicing as well.
"Dealer support" can also encompass the purchasing of expendables or going there and talking with a rep or technician or a tech coming to your place for simple fixes.
Not everyone is handy with a tool in their hands.
Congrats on not having your tractor to be trailered back to the dealer where a delivery fee of $200 is not usurped by a dealer 200 miles away.
May you experience continued success but you do know you may have just haunted yourself
