Same with my 1960s Chamberlain - less the stereo, and I'm afraid the lights have fallen off.
I remember about 1975 two brothers came down from the Darling Downs to Leyland Rocklea with a farm truck to pick up a new 2-70 tractor their dad had bought from the local dealer. They were most disturbed to find that lights were standard equipment on the de Luxe model. "Please remove the lights. If Dad sees them he will have us working at night". Cabins and stereos were still a pipe dream. I am not sure if Queensland had legislated ROPS frames by them. I know NSW had earlier as we sold tractors from Brisbane to Cornstalk cockies who would not buy in NSW as they had to pay for the roll bar.
Mine has the trusty Perkins 354.4 with the pump turned-up a little to around 130 HP which is enough to make the turbo glow all too easily.
Mine did not have a roll bar when I got it, but I fitted both that and a cab after I got it. And it was sold in NSW in 1969. Interesting story - I got it at a clearing sale in about 1995. When I did, my nepohew said "Bloke I used to work for used to have one of them, I'll bet he still has the owners manual, I'll ask him". Next thing I know, the manual turned up in the mail box. And the original owner had written the serial number and the date in the back of it. Same tractor!
It's little known but in Victoria you're allowed to drive a tractor and trailer on your Ls. When I finished my HSC exams in the early 80s my father was doing the harvest so I helped out by towing full field bins to the silo in town - with my Ls stuck on the back of the trailer. Got a few odd looks but all legit. Just checked and it's still the case, but no need to display Ls.
Does anyone think the cockies may stop whinging?
