Help please .... I have hayter Harrier 48 pro and the chain keeps falling off.  Can you tell me how to remove/drop the rear solid roller so I can put a new chain on. Or is there another reason why this would keep happening.

Gardenkit ( Barry I think ) is a member on here gardenkit is his user name like mine is stubby . He deals with mowers . One way would be to look on the mower forum part and when you come across his posts you can click on his name and message him or ... just put your question in the mower section .

Lea,  just to help us help you, can you tell us if its a 480 or a 490 series please?  Reason I ask is because they are completely different in build, and need different methods to do what you ask.  If you could possibly grab the model number off the silver sticker on the back of the machine it would be helpful.

The White info sticker is so torn and dirty is hard to say what one it is. The only clear bit says code486v. I can try and take a picture of the underneath for you if that would be of any help

You're ok, I know what it looks like. 

 

Ideally the whole roller frame including the roller will have to come out to do this job, but it might be more than just replacing the chain.  The roller runs on bronze bushes which normally don't see a lot of lube, and this results in a lot of ware on bushes, but more drastically the shaft itself.  Any ply in the shaft will make the chain go really loose and jam up as tries to jump the teeth, or come off. 

 

It might be wise to remove the air filter and then tip the machine on to its R/H side (looking from behind), then check to see if you have loads of movement in the roller (Forwards and backwards, not end to end).
