    I'm looking at some rural land. The front driveway from road is way too small, steep and winding for a tractor. I do need to bring my tractor home most weekends but I have a paid spot for trailer a few miles away.

    There is a paved access road to the back of the land going up to a county water tower that I can use but it is steep. It starts about 6 or 7% but gets as steep as 14% in a spot or two. My twin screw tractor does have an axle lock.

    Think I'll have any problems bobtailing up that grade? Of course I know in winter I'll have to plan ahead. Total length is just about 300' and it is straight up, no turns.

    I think you will be okay. It's probably more the condition of the road in inclement weather over the grade.
    I live on a remote spread at 8,600 feet elevation.
    My driveway is a mile long, fairly steep with some tight turns. I park my truck and flat at home except in the winter. Although I chain up and bring the truck home a few times during the winter.
    I did change to a more aggressive open shoulder drive which helps when it is wet or muddy. It wwill also help if you put down plenty of gravel for your parking spot.

    I got stuck on one Friday that went from flat to about a 47 degree incline.

    As long as you have nothing to high center on you should be ok. You will get to excercise the low gear. One cool thing is if you ever loose battery power it will be easy to roll start the engine.

    Doing dirt for awhile opened my eyes to what a truck can really do. It’s absolutely insane how high of a grade you can go up. You’re fine.
