I have a B145 wheel horse and it does not want to
move very fast. It loses power going up hills in L. I
have checked the throttle switch and you can tell it
is going in all three speeds with the wheels off the
ground.The batteries are fully charged and the mower
deck runs fine while cutting the lawn.I have checked
for power between the frame and batteries and there is
no draw with a light bulb or meter.It does pick up
speed with the power pulse button pressed. Is it
possible that the drive motor is getting weak. Any
help would be greatly appreciated.
Thank you
Ray
