I have been looking for the dozer blade and trailer for years and finally won them on ebay not too long ago.
I missed out on the front mounted cutting disk he also being sold but the blade and trailer are fine by me.
It is interesting in that the bloke who I bought the blade and trailer off delivered the items to me and while he was here informed me my machine was a very early model.
It has no ID plate, the 3 speed transmission and the narrow rear wheels.
I thought the steering wheel was home made but he stated the wheel was original and does not look like the steering wheel in your photo.
Soon after I also bought from the same bloke a rear axle with a diff and original turf tyres and I also bought from him all the items to turn the mower into an electric start machine.
The axle has a third mounting point which the original solid axle doesn't but I can add this easily enough.
I keep hearing and seeing the Rover Rancher 2 but was there a Rover Rancher 1 ?
I cant explain the odd steering wheel.
I consider all of this info as correct as the bloke I bought the items from use to work in a mower shop who dealt with the Ranchers and knows a lot about them.
