Hello, I have a 4110 with 150 hrs I have had very good service with this tractor so far. I use it primarly with a 6ft med duty bush hog in temps in the 80's. I would be very interested in the engine oil others have used, I understand synthetic is not recomended? also has anyone had a overheating issue? I believe I need to do a through radiator cleaning because there does not appear to be a lot of airflow comming through it now, also my model has the battery that covers the bottom 20% or so of the radiator I understand Mahindra has a kit with a new battery pan that lowers the battery has anyone installed yet? Thanks sorry for all of the newby ?'s
