achyelbows are you in UK?
If you are a man with a van won't be a great solution because, unlike cars which are domestic vehicles, vans are commercial vehicles and are charged to drop waste at the tip (even if the van owner isn't running any kind of business and just happens to drive a van).
The council will collect large items for a fee though. In my area its £20/item, so not cheap if you've got a lot, but easier than sorting out vans/trailers etc and it still costing you.
In my area anyone can weigh scrap metal in, you have to sign to say you own it and give the scrappers your details, the only other barrier is knowing where the scrappers are (mine is on a mini industrial estate off a suburban road and you'd never know it existed from the road), so ask around. I sell my old cars to them when the time comes, they weigh them and usually give me £100-ish depending on the price of scrap.
People will also buy lawnmowers, even broken ones, on eBay if they're petrol/diesel, sometimes they want the parts for other things and the leftover metal can be weighed in or left out by the kerb as a donation to the local scrap collection vans, if they CBA to scrap it themselves. If you just want rid start it at 99p bidding and state "buyer collects" and "broken, spares or repair only" on the ad in huge font.
Riverswims Facebook give away pages aren't usually like that. Try searches like "don't dump donate" and "YourTownName Freebies". I got a 'broken' (turned out it needed a new fuse!) lawnmower that way and an old but fully functional crib.
