The helicopter pilot reported that, while conducting an agricultural application flight, he planned to fly over the top of a power pole. He applied full-up collective to climb over the pole, but the helicopter struggled to gain altitude. He added that, after the helicopter cleared the pole, the main rotor speed reduced and the helicopter "quit flying," so he decided to conduct a run-on landing on the field. The helicopter landed hard, and the main rotor blades struck the tailboom. The helicopter sustained substantial damage to the tailboom. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
