New Holland launches T7 range of tractors
FOLLOWING suit from its new larger T8 and T9 brothers, the New Holland T7000 series now becomes the T7 series, which in essence brings Tier 4A engine emission compliance, four new shorter wheelbase versions and AutoCommand CVT for all models, which cover from 125 to 228hp (rated).
Engines to meet Tier 4A are Fiat Powertrain Technolgies’ Nef 6.7-litre unit, which feature SCR (selective catalytic reduction) technology and hence an AdBlue urea tank alongside the fuel tank.
In addition to the original five T7000 models replaced with T7 specification, the range gains four more in the shape of what New Holland calls standard wheelbase models. The T7.170, T7.185, T7.200 and T7.210 produce between 125 and 165hp (rated) or between 171 and 212hp (maximum), and as mentioned with the option of AutoCommand CVT.
These replace the T6050, T6070, T6080 and T6090 models currently available with Power Command and Range Command transmission options, and Tier 3 compliant engines.
This shorter wheelbase (2,733mm instead of 2,884mm) will no doubt give New Holland more of a hold in the mid-range CVT market, which is popular among both arable and rootcrop farmers, especially on harvester and destoner duties.
AdBlue technology used on the T7 range will allow these models to meet Tier 4A regulations which come into force for engines over 175hp as of January 1, 2011. Operators will need to fill the AdBlue tank, which sits next to the fuel tank, every other time they fill up with diesel, and are informed of fluid level courtesy of an in-cab display.
New Holland says that the transition to using AdBlue will be part of the its sales strategy, and hence is providing a 1,000-litre AdBlue tank and an electrical pump free of charge with each tractor.
New Holland says that SCR technology offers significant performance advantages, with the Nef engines benefitting from what the company calls Engine Power Management (EPM). This gives maximum horsepowers across the nine-model range of between 171 and 269hp, and the technology adjusts engine outputs to suit hydraulic, pto and transmission loads so power is delivered on demand when required, not constantly.
This new found efficiency and SCR technology is reckoned by New Holland to give a 10 per cent reduction in fuel use, and says that the cost of purchasing the AdBlue fluid will be offset by this saving.
Big tractor features
The smaller four short wheelbase T7s have, says New Holland, a host of big tractor features but in a compact package. As well as offering the capacity to fit 650/65R42 tyres, all four smaller models can be specified with the company’s Auto Command CVT, albeit in a simpler format than seen previously. Whereas the T7.220 to T7.270 models retain the existing four-range transmssion, the smaller machines have a simpler two-range affair, controlled by New Holland’s CommandGrip handle. Either 40kph Eco or 50kph Eco variants can be specified, reaching top speed at 1,600 and 1,700rpm respectively.
The whole T7 range also retains New Holland’s SideWinder II armrest, which encompasses the control handle, hydraulics and pto operations. Integrated into the armrest is New Holland’s IntelliView III colour touchscreen which can be used to monitor and adjust a range of operating parameters whilst on the move, as well as controlling IsoBus equipment. All T7 tractors can be factory specified with integrated guidance
Still available on T7s despite being dropped on the larger T8s, the SuperSteer system can be specified for those requiring super tight steering. For those requiring this, New Holland has developed an in-house front linkage which is designed just for the SuperSteer system. With a maximum lift capacity of up to 3,263kg on models equipped with SuperSteer, this increases to 3,671kg on standard front axle models.
