Yes, I can to the rescue at harvest time when a relatives old tractor was playing up, the hydraulics wouldn't work properly and it was lacking power, 'it had been serviced', new filters, etc.berrega wrote:http://www.thenuffieldandleylandtractor ... oblems.pdf
I asked about the Banjo filter, ( I had been swotting up on my Fact Sheets), and got a blank look.
I fished it out and it was filthy, it turned out it most likely hadn't been touched in 20 odd years!
After a good clean with WD40 the old tractor fired up straight away and ran great.
(All done whilst wearing a suit and white shirt, probably not the best outfit to wear!)
