Need info on using wiper motors

[Jack3M]

I know at least 2 of you are using these for dozers. I am using them on a lawn mower, but I note under heavy work load they get way,way hot, like 170 or so by the time I get a thermometer on them.

Since they came with 18 gauge, I just ran 18ga from the Sabertooth 25 amp controller. The wires do not get hot. Not sure if by increasing wire diameter it will help or not.

So just how much weight can you push with these on dozers on the level? My mower is about 75-100 pounds and the hill is steep. On the flat no problem.

Wide open to suggestions and knowledge.
Thx
