How much more capable offroad should a 38 hp Kubota 4WD tractor with a rear diff lock and with 28 inch agricultural tyres (front ones smaller) be compared to a Nissan Terrano II wagon with raised suspension and a rear ARB locker?

New to the tractor game, I had a preliminary run with both on a farm to test them out and found out that

a) the tractor, sitting much higher and having no rear suspension, finds itself in wild angles as it follows the terrain, finding every hole in the ground. The front articulates a little bit to compensate. Lucky no real cross slopes on the land...

b) as a result of the above, the centre of gravity on the tractor is much higher, and with no cabin (ROPS fitted), you need large genitalia to stay on your seat if the tractor starts tilting over. The manual says to hold on to your steering wheel and don't jump at the event of a rollover. How many would stay...?

c) with the front end loader full of dirt the tractor easily bogs down, usually with the opposing wheels turning over, and I had to use the diff lock many times while picking up dirt with it.

Overall, I was expecting the tractor to go a bit better. With the fourby, I have no fear as it has a cabin and metal around it if you drive within reason. Has anyone got any experience or comments, any tips etc. would be appreciated..

Thanks in advance.

HI Redmeatgrr,

I think you are comparing too smaller tractor.
You should compare something like the jaguar 95HP :

This one would go a lot better

If the tractor has smaller front wheels, then it is only 'front wheel assist, to be rated 4WD they must have all wheels the same size.

Not wanting to 'hijack your thread, but what locker do you have fitted? If you don't want your thread cluttered you can email me at patrol6atnetspacedotnetdotau.

Hi Red

Sorry, but what's your point? There used to be around 50 people killed annually in Oz by tractors, are you keen to become a stat?

I don't mean to be too harsh, but you sound a bit like a hobby farmer with too many toys - especially a tractor.

Please don't say you also had your child/grandchild along for a ride -that seems to also go with people messing about on tractors.

I once rescued a neighbour who was slashing her paddock on an old Fergy 35 - she drove under a wire stay from a power pole and snagged the ROPS. I heard her screams and ran over to see the tractor wheel standing, front wheels a metre off the ground with her frozen to the wheel and back wheels churning away! Quite a sight, and a great warning on the hazards of tractors, even on level ground.

Take care!

Regards, John.

Same i think you should treat all machinery as dangerous and use them only for what they are made for. Know of a friend who was recently thrown out of a tractor which resulted in him being run over and rear wheels becoming stuck on his foot while still spinning tore half his foot off. Had to crawl along way for help and was flown away to have foot removed. Couple of days later a bloot clot formed from result of the injury and went to his brain causing him to fall into a coma. Meanwhile other leg hasnt healed and had to be amputated also. His chances of waking from this coma are not very good and even if he does he will be brain damaged and wont have any feet. A very awful accident that really has turned the life of himself and family and friends upside down and inside out. He is a very experienced machinery operator and i had worked with him for many years. I really hope he does pull through and that everything turns out to be ok, but its all in gods hands now. You really dont wish this upon anyone who is just having a play in a machine but accisents can happen so easily.

Unusual comparison Red. The Nissan is going to have trouble picking up dirt without a front end loader & will be hard to fit a slasher on the rear without a PTO ;-)
In my experience the little Kubota's are pretty unstable on hills lifting wheels & side slipping & can inform you when they roll over you don't hang on but jump clear given the chance!(particually without a ROP's) The diff lock does help conciderably with traction when pulling but is limited more by it's lack of weight than power. In wet slippery conditions the tractor would leave the 4by for dead particually with the rice paddy tread on my tyres.
If stability is important then the wide axle tractors would be more suitable.

Craig, A very sensible reply IMHO. ( IF STABILITY IS IMPORTANT THEN WIDE AXLE TRACTORS WOULD BE MORE SUITABLE) As a machine operator for years, I ihave seen that many accidents its not funny!!. The problem is with bloody Kubota tractors is that they are in no way at all designed for hilly country Full stop!!!. I work along side a massey Ferguson 390 4wd tractor every second week, in areas that are so steep That a landrover in reverse can't get enough fuel...LOL. What the bottom line is, knowing the the capabilities of the machine your operating.


Cheers Axle.

The 4wd will easily outperform the tractor in steep country.
In deep mud the tractor should outperform the 4wd, horses for courses.
I know of two incidents where a friendly cocky has gone to help recover a 4wd in steep country and both times paid the ultimate price for offering to assist when the tractor has rolled and killed them.

No no, I wasn't bouncing across the paddock in top gear laughing like a madman with a child on board hanging on for dear life..

I don't want to find the cross slope rollover point (of no return) on that tractor.

But you would expect a tractor with four wheel assist (yep the front tyres are much smaller) go a bit better in everyday working conditions where you would use the tractor on a farm. I actually drove a 2wd tractor Massey 35 a bit when I was a teenager, hence the comparison, and a reference to a nearest known 4WD equivalent, a 4WD wagon.

Where we are located now, a tractor is a must, so is 4WD wagon if you intend not to get bogged down constantly as it rains here quite a bit, and I think they are just tools and not toys.

Hi Shaker, I remember that you also (used to?) have the Terry II, mine is the diesel with ARB rear diff lock which helps a lot on a wet paddock if you have to go there.

I still have the T2, almost 400,000 kms now & still going strong.
What model diff lock do you ave fitted?
I have heard that the rear diff is the same as a Patrol, not sure which model Patrol though.

Hi Shaker,

The RD78A ARB locker can be fitted to the T2 H233 B rear diff.

It's the same locker as with some Y60 and Y61 GQ and GU Patrols.

Interestingly, the T2's rear diff (with possibly some mods) serves as the front diff on those Patrol models. Some Navaras and Pathfinders also have the H233B fitted to the rear.

Apart from one leak from the air comp, I've had no probs. T2 has been trouble free too. Good luck with your T2. I' m sure you crack the 0,5 million mark with no hassles..!

They have actually scraped a bit on full lock upwards but I think that's because there is more suspension flex built into the rear. Wheel spacers are illegal, so you need rims with more offset, but I haven't really looked into which rim would suit.

I spoke to a guy recently who had 31 coopers on the T2, and he said no scraping issues. I have trimmed the front flexible plastic guards a bit for clearance. My 31 rims are Navara steel rims I think, from a wrecker.

Can't believe this post as far as trying to compare the 4WD and tractor. Two different things for two compleley differentn jobs.

Assumin you really do need a tractor then for god sake get some training.
Assuming you have bought it from a dealer then he has a duty of care to give some basic training.
Some dealerships also have small farm days for the hobby farmers to learn about machinery and the safe operation.

There are my thing that can make a tractor more stable from widening heel widths, dual wheel fitment etc etc. Because of the high centre of gravity you feel unsafe a lot sooner than you would in a car but it may be no where nere tipping over. I also tell rookie tractor owners if it feels unsafe then treat it that it is and find an alternate way.

Also make sure a ROPS(Roll over protection frame) is fitted. Something like 98% of rollovers to the rear end in a fatality if one is not fitted.

If you are using the front end loader then you should engage the front wheels as you are taking traction from the front wheels like a seesaw. Secondly if you are filling the bucket then you should have a counterweight on the back to help offset the weight to the front axle and to aid in rear traction.

As said before over 1 person a week in Australia dies from tractor related accidents - don't you nbe next weeks statistic and get some profesional help.

A 4WD (ute) can actually do many jobs safer than a tractor and I would use the ute every time it is possible.

Imagine trying to pull someone out of a bog using a snatch strap with a ROPS tractor. If the shackle on the other end lets go, it may well hit you in the back while you are pulling the bogged vehicle out while riding your tractor. Tie a metal plate onto the headboard on a ute covering the back of it, and you are much safer behind it.

Also, I wouldn't pull anyone out of a bog at an angle tying the rope to the back of the tractor as the pull may lift the front of tractor into the air. I've actually seen this happen. Just use a ute or a fourby. A tractor pulling a trailer to a job requiring some traction on a paddock is much slower than a 4WD ute.

These are just some of the examples where a fourby can do the job of a tractor (and vice versa).

I am comparing the 4WD capabilities of a compact tractor to a capable 4WD wagon. But I need the tractor to do jobs like FEL and backhoe work digging electrical cable runs and sewer runs etc.

I am actually very much safety conscious and I think if should be evident from my postings such as this.

There is no point in comparing one with the other, completely
different design & purpose. I have a 50hp Kubota Front Wheel
Assist with hyd bucket, Fork lift. It is safe if used within its capabilities. Never use the bucket or forks without a suitable
counterweight attached to the rear. Never carry the bucket any
higher than necessary. Extreme care, (& experience) is required to
operate on steep or sloping ground, & to be honest, you dont
sound like you have it. Be bloody careful...if you expect a tractor
& a 4wd to react alike you are heading for trouble. If you bail out
as it goes over you will probably die....do the seat belt up if it has one & confine your usage until you are fully aware of its capability
& YOURS. This is not a personal attack on you, this advice may
save your life......oldbaz.

There are thousands of maintenance company managers, private contractors and operators etc who compare and evaluate tractors vs fourbys as a part of their job or business.

Go to alpine regions of Australia, America, Canada, Northern Europe, for example. You'll see heaps of F series 4WD trucks etc. pushing snow plows there instead of a tractor, in Northern Europe it's usually the Hilux ute with a snow plow in the front. The reason is obvious: Best return for money, tractors are just too slow to get ridden from job to job. But if the jobs are near each other, they may use tractors with FEL's or plows, or a Bobcat.

Slashing is possible by towing a petrol powered slasher behind a 4WD on a paddock. Even log splitting is possible by utilising the PTO from the gearbox of an older 4WD to run a hydraulic pump (if you only using a tractor for slashing, this is a cheaper option for you, a decent Rocky will cost you a couple of grand, but you can't get a decent tractor for less than around 5-10 grand)

I was curious to know what difference a higher centre of gravity, unlimited approach and departure angles, and bigger tyres with agricultural tyres on a compact 4Wd tractor would make offroad. But the only answer is death or serious injury. Lucky my property is all flat. But further by that logic, any car without a padded roll cage, rally seats, 4-point linkage rally seatbelts, a helmet, and ice hockey knee pads would mean death or serious injury too. I might actually buy an ex-rally car for careful public road use. After all, I used to race them once.

redmeatgrr, if I were in your boots I'd look in to putting a rops on.

I was under the impression that they are required by law, though that may only be here in SA.

When it gets wet around here, we park the utes and use quad bikes. The tractor will most of the places the bikes will, but it'll make more mess!
