(ET) C-185 speed control and usage meter problems

["FixItUp" <fixitup localnet com>]

 I got a  Wheel Horse C-185 late last summer,did some minor work on it and 
have used it all spring to mow my yard,not even bothering to install the 
mower deck on my other tractor,and that's really something because the 
"other tractor" is a late-model $6000+ Wheel Horse 522xi with a 48 " deck 
with mulcher,power steering,etc.
 Anyway,much as I like the Elec-Trak I have noticed some things that cause 
me some concern.When I have the mower running,even with a fully charged 
pack and on level ground,when I stomp the pedal to the floor,it is very 
sluggish taking off,it is sluggish for a few seconds and then finally 
takes off at normal speed.I often end up hitting the cruise control/power 
pulse button to achieve any kind of decent takeoff.
 Then,when cutting short grass on level ground,even in D1 the usage meter 
goes past the red,totally pegged.Fact is,even though the tractor seems to 
work fine most of the time,the usage meter is in the red or higher even 
when just driving around.
 I'm starting to wonder if I should consider switching to a different type 
of speed control,or if I should be looking at the motor. I did,by the 
way,totally dissamble the motor last winter and replace both bearings.The 
brushes looked very good. 
  Does anybody have any ideas/suggestions?
Thank You,
