Hi I'm looking at a triaxle 5000gl slurry tank and I'm wondering what size tractor I would need to pull it I'm not in hilly country and the biggest tractor I have ATM is a tm 190 mapped but I think it would be sluggish and our next wagon will prob be a triaxle so the tractor would have to be big enough to pull it would a nh 7070 suit all replies would be appreciated 40,000 would be the most I would spend

I can’t understand why these boys go the 5000 gallon tanker for a tractor. Boys beside me have 2 5000 gallon tankers and are using a 936 fendt and a 8000 series fastrac. I’d buy a 6000 gallon lorry tanker in England which will probably be a 1/4 of the price of a new 5000 gallon and 14/15k will buy a nice fm Volvo. Easier on fuel, easier to maintain, easier to buy and pay for and the tractor tanker won’t be in the field anyway. Tag axle unit and lift axle on the tanker it will be as manoeuvrable and most of all you’d be legal

Maybe it's legal where he lives. 24m³ and bigger tankers are completely legal on road here. Personally i wouldn't use a tanker that big on field, but many do use them.

I’m not sure what your going to get for £40k, a 7000 hour 200hp tractor is all I would say. I pull a 3500 with 200hp and I wouldn’t want any less.
Are you going to use a 5000 as a ferry tanker? Be a hero and double the budget

I don't think a lorry will pull a triaxle wagon it's just that I can get a tanker with a garda pump at handy money and all the drivers here don't have a lorry licence and on land we can pull a 3500 handy enough on a tandem ,I have recessed tankers for softer fields and a customer of mine has a 5000 drawing to pipes and if I had one we could work together

What is the legal gross weight on the road in your country 🤔
Edir, for a tractor and trailer that is

Joskin rule of thumb for flat land is 10hp per 1000l plus 10hp for luck. At 23,000l you might need a little bit more luck although I would say their guide is not far out. I used to pull a 16,000l with a Fendt 939 because it is what I had for other jobs. When I no longer required the 939 I sold it and bought a Valtra T174 (190hp in transport) and noticed no change in output because the Valtra can pull the same tanker as fast as you would want to go safely on the road.

To all the naysayers worrying about having a tractor that can stop the tanker I say any trailer, whatever size it is, should have more than enough brakes to stop itself so the tractor brakes only have to stop the tractor. Also remember that braking force required increases in proportion to weight; speed however is the killer - braking force required to stop in the same distance increases by the square of speed. So to stop the same weight from 60km/hr in the same distance as from 30km/hr requires four times the braking the force. As ever driver attitude and skill will have more to with safe operation than anything else provided the tanker has brakes correctly specified for its weight.

At 50 tons + you want 500+ hp up front in the form of a tractor unit

Nice to hear someone talking sense
