Yes it is Junkman, Got it at my local NAPA store, I think I paid $35 also use a 250 watt magnetic oil pan heater. Tractor starts like it was a 40 deg. spring day when it is really 0 deg. outside. The battery blanket keeps the battery about 85 deg.
I have it pluged into a timer that comes on at 2:00 am and goes off at 6:30 am. A starter is $425 plus $$
