Best place for a tractor is in the shed way before 8!

It only needs to cool it to a defined temperature. Anything below that is likely because the tractor isn't using the power/fuel anyway.surely the cooler the ambient air, the better the intercooler will work
Yet the fuel temperature can indeed get very hot and from experience I do know that even common-rail engines do reduce in power as the fuel gets hot. I have not noticed this with air temperature, but of course it only gets to the mid-20'sC here in the UK regularly in Summer.Modern electronically controlled diesel engines measure fuel by mass not volume so warmer fuel does not affect power.
I quote:
Larry Tracey, Chief Engineer/Project Manager - Advanced Robotics at Major Defense Contractor (2001-present)
Pre-electronic engines metered fuel by volume and not mass, whether gasoline engines with a carburetor or mechanical fuel injection or Diesel engines with mechanical fuel injection. For anything beyond a carburetor, the mechanical fuel system required some amount of fuel to cool the fuel system. That fuel is returned to the fuel tank along with waste heat. The bottom line is as the fuel tank level dropped, the fuel would get hotter. In the late ‘80’s, the Ford V-8 gasoline ambulances had return fuel back to the tank that was so hot it exceeded the vapor point of gasoline. If the ambulance was idling, a common practice, the fuel tank cap would vent gasoline vapor that would hit an ignition source and the result was exploding ambulances became all too common. It is the reason ambulances now are all diesel powered.
Diesels have the same waste heat going back to the fuel tank. Diesel has a higher vapor point than gasoline but as the fuel gets hotter, it would get less dense and result in a loss of power. As Diesel engines switched to higher pressure fuel systems for emissions purposes, the waste heat in the return fuel to the tank got worse and many vehicles had to implement fuel coolers. Full electronic engines have fuel temperature sensors to compensate for increased fuel temperature in order to prevent power loss at high fuel temperatures. The fuel cooler is still required as even Diesel engines can heat the return fuel up to the vapor point. I am aware of one pickup truck program where a prototype vehicle caught fire because of excessive fuel temperature at low fuel condition.
Well that's bulls**t, calving time lambing, silage in catchy weather.If you’ve to work past 8pm your either lazy and haven’t started early enough or greedy. (Apart from a few harvest days on a wet year excluded)
i was under bidderA reasonably tidy 1996 Massey 6180, on small wheels and poor tyres went well yesterday.
Before lunch.... £15500
This ^^^^Is all in your heads
I’m normally working after 8pm because something broke threw the dayThey mostly break after 8pm.
LED lights are one of the biggest productivity enhancements for years. The added visibility makes the job easier, faster and a LOT safer.
I often feel that machines work better in the evening just because the whole thing is a bit cooler. Lower air temperature so less heat being accumulated in the hydraulic oil, air con not having to work as hard and less bright sunlight for the operator to contend with as well.
LED work lights are fantastic, however does anyone else feel that the actual tractor headlights even on brand new stuff is woefully inadequate? Borderline dangerous. Almost have to put the lower side work lights on to see down the side when turning into junctions etc?
