Monty.

This is the same inverter and battery set up that I have. Because I
chose to design and build from scratch, I have the advantage of full
time 24v. A 3hp series wound motor and curtis control give me all the
power and speed that I need.

One question, the Trace is kinda big (22" x 8" x 8" as I recall). Where
are you going to mount it?

While I'm sure that this will work, aren't you sending those corrosive
fumes down and around the tractor where they can damage more things? In
other words, hydrogen is lighter than air and will rise naturally, if
you simply open the battery boxes when charging, you won't need to use
blowers.

Just a thought.
