Countax Ride On Mower Trailer

I bought this Countax trailer in the summer, I have not carried anything in it and looks like the privous owner has not used it, as there is no scratch’s on the inside, the Guy who I bought it off ,said it would carry 750cwt, the trailer tips and there is a latch on the back to release the back door, the door lifts up over, it would make a great addition, to a ride on mower, it would be great for carrying logs. Please note , I live at Brampton,near to Carlisle, as there is loads of Brampton doted about the country .
