Although part of the 6R family, the 6230R and 6250R introduce a new driving style, which we can see filtering down to John Deere’s smaller models in the not too distant future. We take a look at the Mannheim offering in the high-power, low-weight tractor category

When it came to designing the high horsepower, low weight ‘big’ 6R, John Deere did a lot of homework, seeking the opinion of potential customers to see what they wanted from this type of tractor. The end result is the 6230R and 6250R.

One major component that’s shared with the smaller 6R models is the 6.8-litre, DPS six-cylinder motor. This has a pair of turbochargers (hence the PSS tag) with variable geometry, or PVS in John Deere speak.

According to the snazzy brochure, the 6250R should deliver 250hp at rated output and 275hp maximum
output. In turn, the rated output can be boosted by 40hp and the maximum output of 300hp by 25hp when ground speed exceeds 15km/hr or when operating during pto work when travelling over 2km/hr.

Before tucking it into practical field work, we packed our 6250R off to the DLG so the men in white coats could verify its key stats. Here at rated speed (and with the boost function disabled) the pto stub delivered 157.1kW/210.6hp, while at 1,800rpm it churned out 179.9kW/241.2hp — both good results, especially as the boost (after the Deere engineer had plugged in his laptop and re-enabled it) increased pto output to 183.5kW/246.0hp at rated speed and to 193.7kW/259.7hp at max output. These figures, plus a max torque of 1,100Nm, are seriously impressive.
