My 1572 was a bear to start in cold weather. I was going to install a block heater this year but before I could get it done my starter went bad. So I decided to go with the gear reduction starter. WOW what a differance. 40 sec. on the glow plug and one crank and it running. I went out at 4:30 this mourning it was 29 and samething 45 sec and on crank is all it took. I would highly recomend this conversion.
