| We are looking for advise. We have just begun manufacturing a gooseneck grain trailer. It is a gravity flow(no hydraulics)rear dump and holds 340bushel without extensions on. The overall weight of the pickup trailer and 340 bushell of corn was 30,140lbs. The amount of weight transferred on the towing vehichle was only 2000lbs. and the weight carried by the tandem duall 10,000 lb axles was 20,700. So everything worked aut about perfect. My question is as I mentioned it is a rear discharge would you guys be more interested in a side ,center or rear dump. If so why. Second question -as I mentioned 340 bushell is about max on 10k duall axles and about all a pickup can handle without taking out transmissions how much capacity should we offer?Thank you for any input.You can view our new "grain express" grain trailer at www.komfgco.com and email your response to [email protected]

Looks nice, but for me price is the big considertion. I would see that as a special use type unit. Seed tender - so an augar or belt convor needs to be hooked up to it. If it had split compartments to isolate two different product types also. Most farms (and for me) it would need to be side or rear dump for moveable augars at different bins/locations. How does your unit compare in price to the other alternitives out there? (you can compare and answer that question). Good luck and hope to see you product around.

| There is a Maurer gooseneck center dump running around here. Looks like two 10K axles, as well. Thought it was a neat looking little unit. Lower for less wind resistance. Problem, obviously, is dumping into augers. |

Northeast Indiana (Auburn) | You might want to look into using 12,000lb axles to get more braking power. I have a KB 450 center dump sitting on a 16' long gooseneck flatbed with two 12,000lb Dexter axles. I can get around 370 bu of soybeans and wheat and 400 bu of 60lb test weight corn on it. I take the center dump off in the spring to use the flatbed to haul seed and fertilizer. If you could make the rear dump bed removeable a person could put on a short flatbed for hauling liquid fertilizer and/or seed, I would also want more weight on the pickup. I run around 3,000lb on the truck. I weigh around 13,000lbs empty and up to 36,000lbs loaded. The pickup and trailer have a CGVWR of 33,200lbs plus a 10% farm to point of sale to get 36,520 maximum. |

| hi Chris: Thank you so much for your input.We agree not everyone can use it but the people we have shown it to have come up with other uses as well. One guy said that he would be able to store feed in it and use it as needed rather than call the bulk truck out all the time for his small feed needs. One guy said there are a lot of weight restrictions on the his bridges causing him to go the LONG way around. One guy mentioned that the big trucks may require the expensive anual license and need to be d.o.t in the very near future(we all know how hugry the d.o.t. is). We got the hint that there may still be a market because the gentleman that we are making one for had an old 300bushel 14000gvw rated trailer for sale and got flooded with calls. We are starting the cost of our 10k dually out at $8700(this is about 2000 cheaper than the only other one out there that is gravity).We are intrducing it at that price(until we figure out how much money we are losing). Is that a price that will still make it appealing for the niche buyers do you think?
Was the reason that the grasshopper and some of the ones in the past quit because the axles were too light? |

| thanks for your input. So you think the rear dump would be best for the majority of users? Do you have any idea what capacity the maurer was? Do you think 340bushel is about where we should quit for a pickup pulled tailer? |

| Thanks alot for your reply. We have thought of making the trailer more universal but run into a few other problems with height for the discharge and other things. The length of the wagon box is only 10'so there is not a great deal of things that can fit in that small area. We would like to be able to transfer up to 4000 on the truck like we do on the livestock trailers that we build but we cannot move our wheels back any further. What size pickup are you pulling the 36000 around with? Thank you for your input. The only way to learn is by asking. |

| It seems to me, that unless you are going to be building it, maybe for the 450-550, class IV-V trucks, you are going to have to stop around 30K. What is the GCWR on a 1 ton dually? FWIW, if you made it a center dump, you could lower the height, and put more weight on the truck. I would say the Maurer I saw would haul around 300 bu. |

| Since it appears you build other trailers you are probably familiar with liability issues. We had a couple of guys wanting to build trailers several years ago. They didn't want to mess with the insurance issues. I can't imagine all the little lawn mower trailer builders messing with it.
I would think side dump might be a little moe versatile and as another stated a seed auger application would greatly expand you market. Got any pics? |

| How much weight are you putting on the pickup when its 1/2 full or 1/4 full? |

| Thanks for your questions and comments. The trailer by itself weighed 4400lbs. The dodge diesel 3/4 ton weighed 6780. The truck and empty neck of trailer weighed 7440(only adding 660lbs). The truck and neck of trailer with 18,960 weighted in at 9420. There was a weight transfer of 1980 total when loaded and only 660 empty. We did not check intervals in between. I would imagine most of transfer came when the upper portion filled up. Since it fills up from the back - at half full or even 3/4 full there probably is very little transfer. I do have some pretty good pictures of the whole process and how the truck reacted. I will be happy to email you some pictures if you give me your email. |

Northeast Indiana (Auburn) | I have a 2006 K2500 ECSB Chevy with the Duramax/Allison with Timbrens. The only way I could get a side dump to work out was to use three 8,000lb single wheel axles and dump between the first and second axle. A triaxle setup with a 16' flatbed with 12:00 16.5 tires was what I built first. For farm use it was too hard to turn with that length of rubber on the ground. I use spring axles. |

| That looks like it worked pretty good. How long was the trailer itself without the neck? . Is there ever times that you wish it were a rear dump or do you find the side working better? How does the truck do pulling it?Thanks alot for your input . |

Owings, Maryland 38.6856 N 76.6752 W | Good idea, would work great for me, I am looking at getting rid of the farm truck that insurance just eats me up on. I am interested in moving between 350 and 375, center dump would be the best since we always dump in a pit, center dump should also allow more on the truck. The multi use is a good idea as well, slip the grain body off and replace with a 10',12' or 14' flat. would work well in my situation.
Put your company name in big letters on both sides, knock 5,000 dollars of and i'll head up your central east coast advertising department !!!!!!

west central Iowa | Years ago there was an outfit that put an axle and a gooseneck hitch on a regular gravity box that looked like a pretty good deal, but I don't think they were hauling as many bushels as you are. It was a single axle and probably carried a higher percentage of weight on the pickup. |
