After 15 years of mostly reliable service, our petrol-powered lawn mower finally decided to resign from work this year.
Its replacement is an autonomous mower. I have been looking at them for a while and have mostly been sceptical about their capabilities, but with a dealer next door selling several hundred each year, and with prices falling while functionality increases, we decided to buy one.
It operates using a full RTK network, AI-assisted camera guidance and a LiDAR sensor, which it uses to navigate and learn its environment. It has been mostly successful, despite some software-connectivity pantomimes and a couple of accidents involving a fence and the children's slide. Generally, though, it has been very effective. It cuts the lawn in stripes and avoids the children, dogs, trees and most of the flowers.

And it all costs just under £1,800 including VAT.
A quick online configuration with a major tractor manufacturer to add RTK, automatic steering and a control screen to a 180hp tractor came to just under £16,500, and that was before I added a tractor or even a mower for the back. Plus, I would still have to add diesel and drive it.
I appreciate that the two are very different products and are not a like-for-like comparison in any way. But in pure technology terms, how can a domestic autonomous lawn mower be retailed with broadly the same guidance technology that agriculture is charged the best part of £20,000 for?

Yes, agricultural systems are more complex and require a far wider range of safety control systems. But as committed and early adopters of GPS guidance technology, are farmers paying significantly more for a service to maintain its value?
As autonomous technology becomes increasingly commonplace in domestic products, from robot mowers to self-driving vacuum cleaners and AI-assisted vehicles, the agricultural industry may need to ask some uncomfortable questions about the pricing of precision farming technology.
