Top Speed5 MPH ( 8 KPH)
Same speed as ICE foward and reverse as I tached the speed before conversion and after
Accelerationsame as ICE on flat land. A little sluggish on hills.
Rangecurrently getting 23-25 mins of mowing with mulcher blade package installed(this is easier to mow with,being less directional change) but requires a little more current because of the added resistance

originally was 440 lbs. but mower seems to drive the same- added wt. not noticeable.
Tiresfactory. I increased air pressure a bit so it will roll better.

Additional Featuresall safety inter locks were retained.
Special Thanks to Carl Ervin for guiding me through. This has been a fun project. I want to convert my Toyota pick-up next when the funds are available. Thanks to Eric at Olympic Machine in Kings Mountain NC for hub adapter.
