Tandem vs tridem vs splitting super-b

Feb 14, 2020 | 09:49 1 How much will a tandem trailer haul legally?
I'm debating between a super-b and splitting it at harvest with 2 trucks (have 2 decent tractor units, 1 heavy spec, 1 lighter) or a straight trailer.

A tridem is good for 32 tonnes? How much is a tandem legal for?

I've been selling all my grain either at the bin for feed or 3 miles to local richardsons but with a tridem or super-b I would have options. Not sure how far a haul is worth it with a tandem?

Thanks Reply With Quote

Feb 14, 2020 | 09:59 2 Split super b's are not good at harvest because it is tight for a swing auger. The likelihood of running over your hopper increases with the reduced span between the landing gear and tires.

We have a couple tandem trailer a triaxle and a set of super b's. The super b's are going down the road next for a triaxle as it is the handiest seeding and harvest.

Depending on your tare you are 26 to 27mt on a tandem trailer. 3 miles to town you are better off with a cheaper tandem trailer that investing in a set of super b's. IMO. DYODD. Reply With Quote

Legal gvw:
Tandem trailer: 39.5mT
Tridem trailer: 46.5mT
Sup B: 63.5mT

What are guys typically tareing with tandems? 15ish? So 24.5 net?

Father in laws tridem is fairly heavy built, and he tares 16, so 30.5mT on his tridem unit

My supers tare 18.5. Lots of guys 19-19.5, have seen legacies pulled by light spec trucks coming in under 18.

Pup on super is handy, and behaves much like a regular tandem does, you might have to slide your 5th wheel back to avoid ripping off your mud flaps though as the pin depth is shallower.

Lead is not all that great on it's own... it's impossible to get a "legal load" on it as you physically cant get the weight onto the tridem set. Puts a fair amount of stress on the frame and supports as they aren't really designed to be run on their own.

I regularly drop the lead in the yard at seeding time and use it for small amounts of seed or fert when switching crops. Pull the pup with seed and fert. Also drop the lead if its wet at harvest and just pull the pup.

Other thing to consider is it certainly helps to have full wrap fenders on your truck when pulling just the pup as they dont have fenders on the front like leads typically do. Reply With Quote

Feb 14, 2020 | 10:33 5 Doepker tandem off super b with a daycab is just over 12 tare.
Super b with steel Doepker 18.7 or so. The Wilson's are about 700kg more

I agree with treating the lead of a super b with care. They can be damaged if overloaded which is really easy to do Reply With Quote

Feb 14, 2020 | 10:45 6 I am 13mt tare on my tandem trailer. Winter weights on tandem in Sask is 41.5 mt. No winter weights on tridem but you can still haul a reasonable amount during road bans. Super b's in Sask are 62.5mt with winter weights at 63.5mt.

Licensing is alot more on a the tractor pulling a super b versus a tandem or triaxle so there is that too.

It's amazing the differences that still exist between provinces...

I was going off Alberta numbers. Im fairly sure registration is the same for all tractor units here regardless of weight. Even if there is a difference it is minimal. 63.5 costs me ~$100 for a farm plate. It was $3600 when I was commercial. Reply With Quote
Feb 14, 2020 | 12:40 8 our two freight liners , one with steel doepker tandem and sleeper, one with aluminum wilson and day cab both tare at 13,000 depending on fuel
haul 26.5 mt primary , 28.5 winter
was curious the other day saw a tri drive tractor with a tridem trailer , what can they haul? is a tri drive recognized ins Sask?
tandem trailers nice and versatile around yard and narrow approaches , put trailer wheels in ditch on corners enough with them , lol, let alone a tridem Reply With Quote
Feb 14, 2020 | 16:28 9 Winter weight for tandem trailer is 42t and 40t on summer primary. I have a daycab with doepker tandem high side that’s 11.8t full of fuel, but the heavier trucks are high 12’s to low 13’s.

Tough to justify the tridem unless you can load it full. Reply With Quote

Feb 14, 2020 | 17:39 11 I wish I was lighter, Tare is 19,600kg in the summer with 1/2 tank fuel, and +/- 20,600kg in the winter with some snow buildup and two full sets of chains on the truck, can be way heavier though if really slushy. Wilson super B’s.
But I would never go away from Super B’s, they are awesome. Heavy truck though. Truck tare alone is 9,500kg. Reply With Quote

You can only load that if you have the wide front tires and get 6000 kg on the front axle. 11" tires will get you at 39,500 and 41,500. Reply With Quote
Feb 14, 2020 | 19:07 13 I've been splitting super b's for several years and I live close to grain terminals. Its great to split at seeding and harvest and put together in the winter when hauling from the bin. I like the flexibility but like someone else said not great with a swing. A Rodono fixed that problem.

I can legally haul 43.5 MT with Super B.

Tridems Can usually Haul about 32 MT

Tandems Can Usually Haul 27-28 MT

A couple years ago we bought a Wilson Commander Trailer its a Tandem With 3 Hoppers. Same Cu Feet as a Tri, but Can only Legally Haul about 28 Tonnes very handy at seeding time though. lots of clearance and nice to have the extra separation. Reply With Quote

The registrations are in my trucks, but I think the tractor that I pull the trains with is about $2200 and the one on the tandem trailer is around $1000. The trailers are a little over $100 each. Can’t switch trucks without upping the weight on the registration. Reply With Quote
Feb 14, 2020 | 23:13 16 Been using super B’s for 20 yrs. Never run them split. Works just fine at harvest and have no interest in the loss of efficiency hauling some distance or waiting in line with less that 44T. Reply With Quote

    I would think anyone looking at or using auper b’s would want check into the Rodono attachment. Seems to be very slick when you see at the show and watch the video Reply With Quote
