Narrative:
It was very cold morning. I did a thorough preflight of aircraft X. Plane was plugged in overnight and warm to touch under engine blanket. Performed full run-up with magneto checks; cycling of propeller; and carburetor heat application on several occasions during 15 min warm-up. Everything completely normal. On takeoff roll; tail up for easier visual reference. Engine smooth but not picking up power quite as normal. 1800 ft grass strip; 2/3 of the way down; thought of aborting but concern of beyond decision point; felt I could get airplane off ground and high enough to clear hedge and land in field to north. Did not clear hedge and landed in neighbor's field. No injury to anyone but airplane suffered damage. In future; assuming issue was carburetor ice; plan to modify takeoff procedure to include carburetor heat application during initial roll and have mixture leaned for optimal smoothness during cold WX applications.

Title: A C180 DID NOT DEVELOP FULL TKOF PWR AND STRUCK RWY END HEDGES DURING A COLD WX TKOF. PLT SUSPECTS CARB ICE.
Narrative: IT WAS VERY COLD MORNING. I DID A THOROUGH PREFLT OF ACFT X. PLANE WAS PLUGGED IN OVERNIGHT AND WARM TO TOUCH UNDER ENG BLANKET. PERFORMED FULL RUN-UP WITH MAGNETO CHKS; CYCLING OF PROP; AND CARB HEAT APPLICATION ON SEVERAL OCCASIONS DURING 15 MIN WARM-UP. EVERYTHING COMPLETELY NORMAL. ON TKOF ROLL; TAIL UP FOR EASIER VISUAL REF. ENG SMOOTH BUT NOT PICKING UP PWR QUITE AS NORMAL. 1800 FT GRASS STRIP; 2/3 OF THE WAY DOWN; THOUGHT OF ABORTING BUT CONCERN OF BEYOND DECISION POINT; FELT I COULD GET AIRPLANE OFF GND AND HIGH ENOUGH TO CLEAR HEDGE AND LAND IN FIELD TO N. DID NOT CLR HEDGE AND LANDED IN NEIGHBOR'S FIELD. NO INJURY TO ANYONE BUT AIRPLANE SUFFERED DAMAGE. IN FUTURE; ASSUMING ISSUE WAS CARB ICE; PLAN TO MODIFY TKOF PROC TO INCLUDE CARB HEAT APPLICATION DURING INITIAL ROLL AND HAVE MIXTURE LEANED FOR OPTIMAL SMOOTHNESS DURING COLD WX APPLICATIONS.
