http://www.fwi.co.uk/gr/machinery/Tractor-guide.pdfEngine power
Maximum power, whether at rated speed or further down the rev range where engines have a “power bulge”. A second figure shows the maximum power developed for pto and/or transport, as well as draft work, by engines with electronic “power boost”. In most cases, ISO or equivalent ECE power ratings are shown. A footnote indicates where this differs because DIN and ECE-R24 ratings generally give a lower figure for an equivalent ISO power output.
Engine size
Number of cylinders, a “T” for turbocharging, the engine’s swept volume in litres and an “E” where the engine has an electronically-controlled fuel pump or fuel injection system.
Transmission
Tractors available with synchro shuttle (SS) and power shuttle (PS) are listed as separate models with the number of forward and reverse ratios shown, followed by the number of powershift speeds this includes. Prices refer to the lowest-cost transmission where there is a choice. Stepless transmissions are identified as “CVT” (hydro-mechanical) or “hydro” (hydrostatic).
Hydraulics
Fixed flow (F) open centre hydraulic output from a gear pump at engine rated speed and variable flow (V) from a closed centre piston pump. The figures includes output of a separate steering/auxiliary pump where fitted to give a like-for-like comparison with single-pump systems. Mechanical (M) or electronic (E) spool valves – or a combination of the two – are also identified. The latter usually have timer and flow control functions.
Hydraulic lift
Mechanical (M) or electronic (E) implement linkage control installations are identified after the lift capacity. This is not to a common standard as there are many ways of expressing lift capacity – for example, maximum lift is not always available to the very top of the lift arm range. Compare with caution.
Front axle suspension
A new category showing whether suspension is available and the price where it is optional.
Cab suspension
Another new column for the optional price of cab suspension where available.
Price
This is the base list price for the model when equipped with the cheapest of any transmission options shown.
