Thanks for the reply, maybe I should have mentioned that I have been starting tractors in the cold for awhile,
From hand cranking an Allis Chalmers WD, Farmall 400, 560 ( all gasers) in the early 60's, Our first diesel was in 68 a 8000 Ford,
then it was numerous mostly red,574, 1066, 1086, IH hydro, IH Magnums, a little green 4020, 4440, then of course the good green an Oliver 1550.
I traded the old 1550 towards the Branson, that old Waukasha diesel with a manifold heater(same style as the Branson 8050)
would start right down to single digits without being plugged in.
The 8050 without the expensive lubricants would not start in the teens with brand new battery, booster cables to running pickups, even with starting boost from chargers,
The starter just does not have the power, when it would crank it would be a couple of revolutions and then a dead stop, wait a half an hour and it would be the same,
it just needs more starter then the little 2.2 KW they put on it.
also I do like my tractor, it a nice sized unit, it does an excellent job on my driveway plowing snow, loading sand in a sander and grading and ditching, the economy speed PTO works
very good for the generators, tedding hay, brush hogging( light to moderate)
ThanksLou
