Geof and all,
Speaking of converting from ICE to electric, I
could use some advice and/or tips on doing something similar myself.
Ever since I met Shawn Lawless last year at the Louisville Lawn Expo and saw
his ZTR, I've wanted to try something similar.
I recently bought an older (late 80's maybe)
Model 411 Grasshopper with intentions of converting it. It currently
uses an 11 hp Briggs (horizontal shaft) driving two Eaton hydro units that
then drive the wheels through 13:1 double chain reduction
I'm thinking about using two E15 drive motors
and two Alltarx units to drive them. Without a lot of major changes, I
think I can position the two drive motors parallel to each other with one
pointing east and the other pointing west. I'll mount the
smallest possible #40 sprockets to the output of each motor to
drive the first 4:1 reduction.
One possible problem I'm wondering about is
that one motor will be turning it's normal "optimum" direction and the other
will be essentially running in reverse while the mower is going
forward. And visa versa for when backing up.
Do I need to consider modifying the brush
position/location or even possibly the field winding connections such that
when going the predominate forward direction, both motors are in "optimum"
With the Briggs engine gone, (this is a front
mounted deck Grasshopper with the single tail caster wheel) I figure there
ought to be plenty of room to finally do something with those 60+ Saft
BB-600 NiCads I've had for about a year now.
I figure I'll replace the current shaft driven
36" deck with a 42" ET deck and that swap shouldn't be a big
Any of you guys got any suggestions or words of
wisdom for me?
