best lawn mower hills image

I am wanting to use wheelchair motors to pull a remote control lawn mower up hills and through ditches. I bought a used wheelchair and even drove it around to make sure the motors worked before I took it all apart. Electric motors normally have a positive and negative power input. However, these motors have two small white wires also. What are they for? And, do I need to use them for anything?
Answer
It could be for a shaft brake. You would energize the two white wires and an internal solenoid would pull back a brake pad or lock pin and allow the shaft to turn. This would keep the wheelchair from moving further once the user stops it or releases the control.

How best to approach a hill with a gas lawn mower?

Part of a lawn I have to mow is on a hill, more precisely a fairly steep short berm. I notice that my gas lawn mower (toro brand, 4 stroke engine) has problems with it and tends to eventually stall and definitely burns more oil. Changing the landscaping to not-lawn is not an option. I am wondering if there are differences if I approach the hill sideways or better from top or bottom? Sorry if that is a stupid question but I am pretty clueless about gas engines in general.

Hi, tigrillen. Not a stupid question at all. Two things, one being the mower.
Some old Toros actually had an oil pump in the engine, while their standard mowers these days do not. On a steep slope, the new ones may have some oiling issues as a result. I used to keep an older Lawn Boy with a two-stroke running just for this issue. Lacking that option, you might even consider using a line trimmer to keep things neat, rather than a mower (gets pretty good with practice).
Second thing is that approach with a mower. If the slope is steep enough to potentially roll the mower when trying to go across the slope ("traversing"), have to just go up and down. Then the issue is not slipping when coming down and getting your foot under the mower deck. (A relative is missing a couple of toes from doing that.) Don't mow damp turf (i.e., avoid a lawn "water slide"), wear good shoes, and stay a little off to one side. And keep kids and pets well away while doing this.
