Trailer for ride on mower

I am hoping to redesign our patio and need a trailer suitable for use with my Hayter ride on mower, to take the waste earth and rubble to the top of the garden. Any idea what kind of trailer I should be looking for?

 

This is the Hayter home page, so if you can't find the info you need, maybe you could ring them and ask? Guess you'd prefer a non-Hayter one, as it would prob be cheaper, but this would at least give you a price to work from...

Thanks for those links. I've left a message about trailers and also phoned my local garden machinery shop. All the trailers state their specifications, but the Hayter Mowers do not state suitable for pulling loads, or what weight of load they can take. I really don't want to damage the mower.

 

I use mine for pulling the big green trade bins around the school two at a time with no problems
