Basically you mount wheelchair motors to a electric lawnmowers and design a control circuit using relays or a motor driver.
But if you feel up to the challenge, why stop at remote control, make it autonomous. It is hard but you can base your work on previous machines/

I saw someone selling them on Ebay a few weeks ago, ... wonder if they still do.  They were pricing them at ~$2,500

you could search eBay for 2 wheelchair motors and get some motorcycle battery or something or even just get the wheelchair battery too heh

just like HDL_CinC_Dragon said.

I used server backup batteries. Just search ebay for wheelchair motors and for 12volt 20ah batteries. ah is how long the battery can run on one amp. SO for that battery it can run 20 hours at one amp. Find the requirements for the mower and for the two motors. Then find an appropriate battery. Im assuming itll all work on 12 volts.. Sooo, if your motors draw 10 amps continuous and your mower draws 5 amps continuous then thats a total of 25 amps. SO i would suggest getting a 12volt 50ah battery so it can run for 2 hours before recharging.

Email me if you require any help whatsoever ([email protected])

Guys,

I built this one last year:

I will be updating the site soon with some improvements to the electronics.

Later I want to add a 24V alternator to charge the batteries while the mower is going.

Cheers,

TnP
