Get the bottom hose off and give it a damn good bash out with a hose. The faster the water the better and the longer the better. If you can be arsed take it out and shake holy hell out of it whilst flushing both ways. Keep going until the water runs clean and then do it again. Taking a rad out is a few bolts and half an hours work, its beginners stuff. You can even get a pot of central heating cleaning jollop and throw that in a few days before to loosen things up. If its knackered, this will show it up and its time for a bermarch replacement that will cost just over a ton and keep you going for a few more years.
Its what we do as trattor owners. Thats what separates us from the twonks with micras.
