Living in the U.S. but having a house on a large lot in Bo Sang, my Thai neighbor Cuts the grass.  Usually, he waits until it’s too long to easily cut with my push mower and cuts it with a weed wacker.  Because of COVID, I can’t come over until next year but would like to find a good quality riding lawn mower in the $3,000 range.  It could be from anywhere in Thailand but Chiangmai would be preferable.  The other option is to ship our riding lawn mower from the U.S. when we move back to Thailand and use my Thai wife’s personal exemption from duty, but doubt if a lawn mower would qualify.

Continue cutting with weed whacker until you return.  Maintenance and operation of new riding mower should be managed while you are here.  You can probably ship your from US, confirm with shipping agent, easy.

They show this one on Lazada....

It's listed under lawn tractor....
