There is a track drive kit that would slow the unit down (40%), but it's pricey and may also have some other attributes you're not looking for.
I'd forgotten that I could turn this machine into a DLET with the kit, which would be very nice speed
and traction-wise. I was originally looking at one but went for wheels because I have to clear an
elaborate wheelchair ramp which has hairpin turns in places. Still the tracks may be the best
solution. Thanks.
