Tractor Parts

Dave has pointed out that i am skimping on the pictures and the general content of the Blog at the moment (see comment to last posting). The photo a day is falling way behind. Dave has set himself an even harder target of actually taking the photo on the day he posts! I can at least cull some sort of junk out of the archives and feel that i have made some sort of minimal effort... So what do we have today? This is the water temperature guage on one of Dad's tractors. I have no idea what this tractor is except it is red and mostly rusty...
