Riding lawnmower steering servo

[tonynsx]

I’m trying to find a steering servo for my riding mower so I can turn the steering. I’m not sure how much torque is required to turn the mower steering wheel, but these servo apparently does 60KG (130 pounds).

These are the 2 servos I’m considering.

Hi @tonynsx

If you own a dynamometer ( or maybe you can borrow one), you could simply measure force needed to turn the steering wheel.

Sorry for the late reply. I’m using a wiper motor and it works.

Great! @tonynsx
