Considering that the cooling system was engineered to meet (cool) the heat load demands of the engine under worst case conditions, the overheating problems have to fall into one of the following two catagories:
(1) There is a malfunction causing the engine to produce a higher heat load than was designed for, or
(2) There is a malfunction that prevents the cooling system from cooling the way it was designed.
Possible examples of problems in category (1) include but are not limited to...
-- a defective mower or other drive train component that results in abnormal resistance that causes the tractor's engine to work harder, or
-- a clogged air filter, or other problem relating to fuel/air mixture, or
-- other???
Possible examples of problems in category (2) include but are not limited to...
-- clogged radiator fins which reduces heat transfer
-- blockages inside the radiator reducing coolant flow
-- wrong mixture or type of antifreeze which would reduce coolant flow or heat transfer properties of the coolant
-- other???
Other notes:
<font color=blue>I've been running at a little back from full throttle</font color=blue>
Since I had engine problems a few years back due to overheating, I added a temperature guage where the sensor was mounted in the top of the radiator on my B7100. I can't explain it, but when mowing it runs slightly cooler at full throttle than it does a knob width below full throttle.
<font color=blue>My basic question: should a B7100 be able to handle a 48" mower?</font color=blue>
I have the 48" mid mower installed. I also have connected my LandPride 60" rear mower (that I normally use on my B2150) and didn't notice much of a difference in the B7100's mowing performance. Therefore, I'd say that the mower size isn't your problem. There could be a slim chance that your mower's gearbox or blades aren't turning as freely as they should thus causing the tractor to work harder.
<font color=blue>The antifreeze is Peak (orange, permanent) </font color=blue>
I took my B7100 manual to work and accidently left it there today. Seems like it mentions "permanent" antifreeze, but I can't remember if it said "Use It" or "Don't Use It". I know that mixing different types of antifreeze (for example, environmentally friendly and the old standard type antifeeze) can cause undesired reactions that can have disastrous results in some automobile engines (seems like I've heard that it eats away at head gaskets of some GM products).
Hope this helps,
Kelvin
