With the talk of pickups pulling trailers exceeding their GVW ratings on both how about this.I'll bet that there isnt a single 2 ton farm truck in the country that doesnt far exceed their GVW rating.I went out and checked mine this morning and was surprised.Its not something that you think about.

My 1968 IH 1800 2 ton farm truck has a GVW rating of 22,500 lbs.It has a 16 ft steel bed with hoist and weighs 9800 lbs empty.It has (6) 9.00x20 tires rated at 4610 lbs each.

It has no extra top sides and always weighs nearly 30,000 lbs loaded at the grain elevator which is legal on the axles.There are other 2 ton grain trucks with extra top sides hauling far more grain than mine.

If I were to load it by the GVW rating I could only haul a little over 200 bushels which would make it worthless.

My 1969 IH 1600 Loadstar 2 ton farm truck has a GVW rating of only 18,200 lbs and weighs 9200 lbs empty.It has a 16 ft steel bed with wood floor and hoist.The steering tires are 9.00x20 rated at 4610 lbs.The rears are 8.25x20's rated at 4050 lbs.I'd have to change the rearend to put 9.00x20's on it.

I usually weigh 30,000 lbs loaded.If I loaded to the GVW rating I could only haul 150 bushels which would make it absolutely worthless.

Would you say that these trucks are safe or very unsafe?Lots will say that I should get a bigger truck.OK,if I were to buy a 10 wheeler that could weigh 48,000 lbs I'm guessing that with a legal load that I would far exceed my GVW rating on it.It would probably only be in the upper 20's-low 30's on GVW.

OK,I went out and checked the GVW on my old 1966 CO 4000 IH road tractor with a 318 Detroit and a 10 speed.Its GVW is 35,000 lbs.If I stretched it and made it in to a 10 wheeler that can weigh 48,000 I would exceed the GVW by 13,000 lbs.Thats way more than my 2 ton trucks.Would that be safe or unsafe?

So,if we wanted to get technical a semi with a grain trailer would be the only way I could safely haul grain to the elevator.

Just something to think about.How much do some of you haul on 2 ton trucks?

GVW ratings often times have little to do with the weight hauling or towing ability of the vehicle. A good case in point are the 70's and 80's models of Ford pickups. Ford always rated manual transmissions much lower than identical auto transmission models. Would the Ford auto actually pull more weight than the manual? No. Dodge's mid 90's models usually rated the manual trans. models higher. The fact that Ford had light clutchs and manual transmissions and Dodge had weaker auto transmissions has nothing to do with what they will haul or pull, at least for a while. But their warranty repair costs did. GCVW ratings are affected by things as simple as whether the vehicle has a 3 row radiator or a 4 row one. The same truck with different tires will often be GVW rated differently. Did the truck originally come with 8.25x20's or 10.00x20's? Dodge had a interesting GVW system in the 1 1/2 to 2 1/2 ton trucks in the late 60's and early 70's. The GVW plate had the highest possible weight rating for a particular series of truck shown on it. On a D500 series it was 24000 lbs. But if it came with 8.25 tires the truck was actually a 19000 GVW truck. I think Chevy did some of that too, at one time. Engines also change ratings. A 300 Ford six was rated way less for towing than a small block V8, like the 351W. But 300 sixes were in a lot of F600's. Will a 300 six pull what a 351 will? Of course, maybe a bit slower. Small block V8's weren't in F600's. Springs are another big thing. A truck factory equipped with a set of 4 or 5 leaf auxilary springs usually has the same GWV rating as an identical truck without them. Rear axle ratios are another thing. A 4.10 gear will be rated higher for towing (GCVW), and sometimes even hauling (GVW) then a 3.55 ratio will be. In real life will one haul more or pull more than the other, of course not. Will the 4.10 do it longer before a breakdown? Probably. GVW ratings really don't mean much. They are manufacturer assigned number with an eye cast at warranty costs as much as anything else. IE: "You exceeded your GVW? Your warranty is now void."

You are so right! But don't forget that GVW is now a marketing item. That's tending to bump up the ratings a bit.

The semi truck is not the only way to haul grain safely. They make many 6 and 10 wheelers that can haul the load. I have driven 6 wheelers that had a GVWR of 36,000 lbs and a GCWR of 80,000 lbs with proper trailer axle combos.
38,000 lb rear ends are common in 10 wheelers such as dump trucks; and you can even order the heavy duty 44,000 lb rears.

Now is what you are doing safe????? ? Like the others said that depends on the condition of the truck. Being over weight causes more breakdowns from broken springs and such; and extends stopping distance. But on the other hand it is done daily by some with no ill effects.

The funny thing is a scale master is only concerned with inches of tire touching the ground when checking weights at a scale. Now if you get stopped for a road side check they will most likely dig deeper and find you are over your weight rating.

Where I think people get into trouble with being over weight is when we add a trailer. Trailers and loads that are to big for the truck being used is a death trap waiting for a place to happen.
Over weight trailers can cause a trucks front end to get light and even leave the ground with bumper hitches. Over weight trailers can cause a truck to start swaying to where the trailer is controlling the truck rather than the truck controlling the trailer.
And lets face it most weekend trailer pullers have no idea of the problems they have brought on themselves when hooking a trailer on the back of their pickup. They expect to pull the trailer in the same manner as they rush to work every day in city traffic.
Once we get above the 1 ton and smaller crowd being a little over weight is more of a tearing up your equipment problem. Heck I play the cat and mouse game with the weight master all the time because I am 1000 lbs over here or 1500 lbs over there.
lbs = $ and you got to haul the lbs to make the $.

Heres the old 1968 IH 1800 earning its keep during the 2005 corn harvest.It has 350 bushels on it.It would easily haul another 50 bushels with 6" top sides but I'd be over on the axles.

These old IH trucks are so over built that you would really have to work to tear one up.They have done the job for 40 years and would do it for 40 more if parts are available.I go over both trucks completely every year before wheat harvest and have had no major problems.Both trucks make a 24 mile round trip on gravel roads to the elevator and I've never had to walk.

As I stated before every 2 ton farm truck in the country far exceeds their GVW when hauling grain.DOT knows it and could take every 2 ton truck off the road if they really wanted to by just looking at the GVW plate..So far they havent wanted too!!These trucks are all that small farmers can afford.The neighbors that farm 2000 acres or more have all gone to semis.Even 10 wheelers are getting to be a thing of the past.

I expect that these 2 ton farm trucks have one of the lowest accident rates in the U.S. They are driven low miles on rural roads mostly by people that know how to operate them.My liability ins only costs me $80 per year per truck.They must be rated as being pretty safe to get those rates.

Both my old IH's have hauled their last loads for me.I'm a part timer and recently rented the 320 acres of farm ground out for 2008.Its time to take life a little easier.

well it may not be strictly leagle, but then the truck has been doing the job for almost 40 years, i would take some time to really inspect both rigs this winter as stated already overall condition of the truck [ brakes tires, frame suspension ect] has more to do with saftey than a extra few tons of grain, i have a friend with a 2 axle ih S series truck it has 22.5 tires on it and routinly grosses 34,000 he's been weighed but never got a ticket, if the 10 wheeler is built out of a class 8 tractor it will weigh around 23000 to 24500 empty depending on its equipment and can gross 50,000 i do it everyday and get weighed by the dot at least twice a week, [ just dont hop up on the scales with 51,000 ]

Safe or unsafe is that your question?

It has a lot to do with equipment condition, brakes, tires, springs, shocks, frame cracks, rust etc. Can't tell from this angle, maybe if you moved the truck closer to the monitor...

But, while you commonly do it, that does not make it right or safe (or intrinsically unsafe for that matter). Unless MO has a farm truck overload loophole, it would make for a dandy of a ticket.

I saw on a program once where GM's investigations showed that EVERY truck they sell will be overloaded at some point in time. Guess it's common!

Up in this area in the fall during wheat harvest there isn't a truck that is legal I bet. My neighbor has a Ford tandemn and had it loaded down pretty heavy and the highway patrol stopped and invited him to the way station. He said the results were $400 on his credit card. Normally the patrol is pretty easy on drivers at harvest time.

Theres a farmer in this area that had a mid-late 1960's Ford F-800? 10 wheeler with an Allison automatic.The bed on it holds over 700 bushels so he was slightly overloaded most of the time.

He now has 2 semis and may have sold the Ford.It was a nice looking truck.I wish that I had a picture of it.

I know another guy in Kansas that has an early 1970's IH 10 wheeler with a 238 Detroit in it.The 22 ft bed on it will hold nearly 700 bushels.

My granddad's favorite story is about getting weighed on the old scales the DOT guys carry with them. He was in a 60's or 70's GMC 2 ton with a 40 ft float hauling seed. He said he pulled up to the scales and the truck wouldn't pull itself onto them. He got a running start and broke the scales. Since they couldn't weigh him they told him to go on. Not sure if he inflated the story or not but its pretty good.
