Sharp-looking design

Although a base spec machine, it doesn’t miss out on the good things such as turnable front fenders

A closer look at the Deutz-Fahr 6155G

Hydraulic couplers are easy to use, well spread, and have strong dustcaps to keep them clean when not in use

Roof lights may be few and far between but they are powerful

The small but clear dash allows plenty of forward visibility

Farm Trader's Jaiden Drought puts the Deutz-Fahr 6155G through its paces on a Taranaki farm, testing it out on a variety of tasks

I wouldn’t be speaking out of turn in making a bold statement about the fact the new range of Deutz-Fahr tractors are up there with the best-looking tractors on the market. This is largely thanks to the Italian styling by Giugiaro Design.

Although not usually directly linked to tractor design, this is a famous automotive design house, better known for the DMC DeLorean, the original MK1 VW golf, many high-end Ferraris, and most of the stylish Alfa Romeo designs

Back to tractors, however, and the Deutz-Fahr G Series showcases some of that Italian flair in the bonnet design, throwing away many of the impracticalities of style (like the unnecessary 12 ornamental pillows on your bed).

Instead, the design has been scaled back to provide many of its bigger brother’s creature comforts but more suited to the price-based tractor buyer looking for plenty of the bolted metal stuff and less of the shiny chrome stuff.

High lift bonnet makes daily checks a breeze

Power Farming in Taranaki were kind enough to give me the chance to test-drive the Deutz-Fahr 6155G for a few days to get a feel for what the series has to offer. The model I tried was the base spec’d Vista; the up spec’d Summit is also available. The most notable differences between the two are in the front suspension, 50km/hr capability, and a CCLS pump, but more on that later.

Engine

The powershift gears on the loader joystick simplify loader work

The Deutz engines are well known for frugal fuel usage, and the proven six-litre six-cylinder Deutz engine in the G Series is a farmer’s best friend. Being Tier 3 means there’s no AdBlue (I can hear your sigh of relief already).

Four models make up the G range, with output from 141hp to 203hp. We had one of the middle children, the 155 powershift, on show. The high-pressure common rail gave 11hp boost with the 155hp (rated at 152hp) achieving a max output of 163hp.

However, most impressive is the fact that the max torque figures are achieved at just 1400rpm. This is using the high torque, low rev principal of many of the large displacement engines. In a tractor of this size, it means high productivity and low fuel burn – all day!

Transmission

Bird’s eye-view of the controls

The 6G series has two transmission options: Powershift (in the 135 and 155) and RCshift in the (185 and 205). While the RCshift has gained a popular following due to its user-friendliness, I prefer to  stick to the Powershift gearbox as spec’d in our trusty steed – the 155.

The ZF branded 30/15 box has five ranges, with six powershifts in each range going forward and five ranges of three powershifts in reverse. A 54/27 gear creeper is also an option. A key feature of the Powershift transmission is the fact it offers 17 gears in the main working in the 5–20km/h band.

This is more gears than most of the competitors have in their whole transmission.
More good things include speed matching, a hand-operated de-clutch button, and – also on our test tractor – powershift up/down on the loader joystick. Speaking of loader work, this is the bread and butter of the G Series, and to complement this, the fwd/rev shuttle has a five-speed modulation control to customise to your preference of aggression. 

In the transmission department, the G Series is like the gift that keeps on giving. The 40km/h trans has an Eco feature, meaning top speed 40km (50km optional) all happens at just 1575 rpm. To add another level of safety, both on the road and in the paddock, four-wheel braking – well respected with the Deutz-Fahr/SAME brand – can be ordered from the factory if requested.

Operator environment

The colour matched loader and tractor make for a handsome package

The Deutz-Fahr G Series features the PowerVision cab. First impressions once inside is of the familiar Deutz outlook: bright and spacious with familiar colour-coded controls. One personal gripe is that if you’re tall and wide like me, you need the seat pumped up so your spine doesn’t penetrate the top of your skull on the first bump, but for me, my extra height means I look right at the top of the windscreen.

Large doors provide easy cab access

This will be an issue for few, however, but then my mum always did say that I was special.
Back on a more positive note, the cab is equipped with mechanical suspension (giving a silky-smooth ride) and has the new ‘detached cab from hood’ concept. It’s pretty self-explanatory what that entails, but in essence, it reduces vibrations and the noise level by as much as five percent from previous models.

I can remember all the way back to the MK3 Agrotron being known for its quiet cab and that was 18 years ago. I’d better switch subjects before I figure out how old that makes me now!

Hydraulics/PTO/ Linkage

Hydraulic flow to the rear spools is easily adjusted from the back window

Around the rear of the tractor, there’s plenty more good stuff from Deutz. A dedicated steering pump provides a constant 42L/min. In terms of the main pump the Vista comes with, this is a 110L/min gear pump, while the Summit spec’d machines have the 120L/min CCLS variable displacement pump.

Up to four mechanical spools can be optioned, with electronic valves available on the professional series variants (not on the 6G). All come with the electronically controlled rear linkage. Lift capacity of 6.2 tonnes is ample, although annoyingly needs to be unlocked every time the tractor is started.

The height control dial was easy enough to use and provided smooth lifting and lowering, even with heavy bales on the back. The norm is now to include four-speed PTO, and the Deutz hasn’t let the side down in that department. There’s push button start, mechanical gear selection (bonus features of Auto PTO), and external start/stop as standard.

Verdict

Plenty of work capability

Most of the competition in this price bracket ends up being a version of a smaller model jacked up to achieve the desired weight/power to match it with the pack. However, the Deutz-Fahr 6135 and 6155G are the opposite; big boys (/girls) toys that have been on a diet, kitted out with a frugal Tier 3 engine, a trusted ZF transmission with plenty of gears in the working range, and all coupled with a quiet and spacious engine.

The Trima loader is strong, robust, and good looking

I had the Trima loader fitted and have no gripes with Alo branded machines; top-notch all round. A 163hp tractor with a high-quality loader for low $130k throws the $1000/hp argument out the window, and with the newest Deutz-Fahr models on the water arriving with larger tyres, the argument for investing becomes even more compelling.
