Made it in and out of a 2300' grass strip in AL - 600' elevation, dry field, 1/2 fuel, 1 light passenger (I'm pretty light, too), light wind, 65 degrees. My home base is 3600', and I usually get it down and stopped without much braking before the halfway point. Taking off and climbing out was no issue with 3-blades. I've got ~80 hours in the plane.
You shouldn't have much problem. Just fly over it first to check for rough spots - the rubber pucks aren't really ideal for off-roading. Call someone there at the field and ask how they maintain it and get the current condition of the grass. Do some test landings on pavement and be sure you can get it down and stopped, or at least to a speed where you can make a U-turn, before 80% of the grass runway distance without much braking. Depending on field condition, the inability to do normal braking is almost cancelled out by the way the plane rolls with more resistance on grass.
