The equivalent of a little grey fergie!
is the Honda Fourtrax. Weight puller (for a quad - the 420 is rated for towing up to 385kgs), has power steering (on motorbike handlebars), since around 2004 has had selectable 2wd/4wd. Simple, maintainable workhorse. New the 420 is the smallest and is a very capable machine. Secondhand or reconditioned, you may be able to find a 350, but they are getting on now,
I have owned a 350 and three 420s, and used other people's Kawasakis, Suzukis and Yamahas. Honda Fourtrax for me every time. Just make sure you use a clean filter to pour the fuel in, and don't allow bits (or rain) to get into the petrol tank. And keep the oil topped up.
(In 2006, we bought the farm with its 350, which we worked
hard. After a few years we upgraded to a new 420. When I left for another farm I bought an 8 year old but low mileage 420 and neglected to keep the oil topped up, so the engine seized. Entirely my own fault. Bought a reconditioned high mileage 420 in around 2014, which I carefully maintained!, and is still going It is not worked hard.)
