New Holland TV6070
New Holland has a tractor that could open up a whole new market in New Zealand – the bi-directional tractor
- Can carry implements on each end so is faster to complete jobs
- Gives the same driving feel in both directions
- Incremental control of the hydrostatic drive system
- Incredible turning circle
- Massive loader lift capacity
- Reduced wheel slip as all wheels are driven at once
- Simple controls
- Huge hydraulic capacity
The Bidirectional TV6070 features a large wheel loader-sized bucket, dual implement use via three-point linkages on each end, and a small turning circle.
The permanent 4WD TV6070 can be equipped with a drawbar, PTO, hydraulics and three-point hitches at either end. The tractor can push and pull implements at the same time through its four same-diameter wheels. Non-directional tyres came standard with the TV6070.
Driving the TV6070 took a while to get used to because of the centre pivot, however being reverse steer, it really doesn’t matter which way you drive the TV6070.
The combination of a suspended cab, electronic loader damping system and the four same-diameter wheels make driving along races much smoother than a normal tractor. What most impressed me was its really tight turning circle, where the rear wheel track simply follows the front wheels.
The tractors are gentle on the soil and there’s no scuffing from the tyres when turning because the wheels track along the same path.
However, I quickly found there was quite a bit of slop in the steering linkages that made it a little harder to keep in an easy straight line. The level of steering control didn’t change or alter when driving the TV6070 ‘backwards’.
For me, the pivot steering system was the hardest to grasp, just because it’s more like driving a wheel loader than a tractor.
Driving the TV6070 is different enough that a typical, experienced tractor driver might need a couple of weeks to get comfortable with everything. And that is pretty much where the hydrostatic drive system sits too; it’s much the same as any construction machine with the wheels constantly driven by hydraulics.
Driving the TV6070 is an up to 100 percent bio-diesel fuel compatible 6.7-litre six-cylinder diesel engine. Fuel into the 155hp two-valve Tier 3 motor is metered by individual Bosh fuel injectors, pressurised by an intercooled turbocharger. 105hp is available at the PTO as some of the power drives the hydrostatic drive system.
Transmission and brakes
The hydrostatic transmission has eight infinitely variable speed ranges going from 0 to 30kmh, governed by a simple forward/reverse lever. On the lever are the linkage rise/fall buttons. I could select any of the eight ranges by switch, push the lever forward and drive off. The more I pushed the lever the faster I went.
I could drive anywhere in top and there are no discernable range changes being hydrostatic fluid drive. It’s designed to chop down automatically when load comes on then return to your selected range when the load comes off.
The brakes are hydrostatically controlled too; as such I had to pull the lever into reverse to stop quicker. A back-up wet disc brake is actuated by a foot pedal, although I didn’t think much of it.
Inside the cab is a 210-degree rotating "Turnabout" console. This consisted of an up-spec pneumatic seat connected to a wrap-around control consol that included the steering wheel and dash. When you turn the consol around, the whole lot rotates in unison including the steering wheel.
Although there is lots of room, because the consol rotates there is no room for a training seat, or much else. There’s good external visibility.
Missing though is New Holland’s class-leading sound damping qualities, particularly above 1800rpm.
There were fewer controls than I expected to see. The big loader is operated more by foot levers rather than the hand lever double-ups. Mostly because the style of driving this machine will see your right hand always using the forward/reverse hydrostatic drive lever.
The far left floor pedal operates the rake up/down, the pedal next to that controls the loader rise and fall, and the right pedal operates the self-levelling bucket. I thought this was pretty good.
