First, I haven't read every entry in this thread so if this is a repeat post, can't remember........
Where are you? We are in the Franconia Notch area.
I have a 30hp New Holland 4wd w/ FEL that I use around our land and maintain our .4 mile unpaved road- grading in summer, snow blowing in winter. Rake, grading blade, box blade, chipper and snow blower.
Our T1510 has been flawless.
