We fly in at sod farm so you never know what length the grass will be. We had an LT 40 out there last week and he had to hold full up elevator to get the plane off the ground. He couldn't get ground speed any other way. Just think of you tri gear becoming a tail dragger (you just want the nose up and the prop out of the grass). The best solution is some big ol' tires! The other part of the problem is landing. As soon as you hit that grass if you nose isn't high you are going to flip over on your back and hope you didn't snap off your rudder! I running 3 inch tall tires and I'm going to move to 4 on my tail dragger.
