Any that draws less than 32 amps at stall (actually, rule of thumb is to oversize a bit, so maybe anything that draws under 27 Amps).

Most wheelchair motors draw 20 amps so most of us that use them us Sabertooth 2x25.

So in other words 2x25 sabertooth can draw 25 amps per motor correct

@Jaimito I doubt your motors will pull that many amps unless they stall... at any rate the sabertooth will shutdown to protect itself if the amp draw is exceeded...

Yes, 2x25 can handle 2 25 amp motors, although like I said, it is wise to allow a little overhead. But, like Richard said, the Sabertooth has good protection built in to prevent damage in an overload condition.

So i’m very interested in putting together an rc lawnmower,, i got the toro with key start, also purchased a spectrumDXE remote control and reciever,, just recieved my 2x32 sabertooth yesterday, my biggest problem to solve is: how do i go about starting my mower with the remote what other components would i need to purchase?

Jaimito, I used a 40A solid state relay for my RC lawn mower starter. You just need to a put a pwm switch from your receiver to the SS relay. You can get the SS relay for about $8 on eBay. You can also get the PWM switch on the bay for about $4.

For the motor controller I always use the 2x32 sabertooth being that is about the same price as the 2x25 with plenty of extra amperage.

Anything else other than 40 amp ss relay,, and what pwm switch the one with speed control or a different one? any thing else i might need to complete the startup? Which wire will be used on the key start from mower

Aside from the ssr, you will need a simple RC PWM switch to switch the ssr on/off, like the ones you use to control lights on an RC vehicle. You would run the positive wire of the starter through the ssr. The starter is already grounded to the lawnmowers chassis. Also keep the starter's factory in line fuse hooked up for protection.
