Add brakes and suspension to small dump trailer?

[John_Mc]

I have an old CAM Woodsman dump trailer that is 4'x8'. I got it mainly for us behind my tractor in the woods. It's great for that: since the wheels are tucked in under the sides the narrow profile makes it easy to maneuver down the trails in my woods. It's got a 3500# axle, but no brakes and no suspension (the axle is just bolted right to the frame).

I've been wondering about adding electric brakes to it and possibly adding some sort of suspension. I do occasionally take it out on the road to grab a yard of stone, topsoil or firewood. That's where the lack of a suspension is really noticeable. The brakes would just be a bit of a safety feature, especially coming down some of our hills when hauling a load of stone. How tough/expensive would it be to do something like this? Am I better off adding brakes and suspension to what is there, or just putting a whole new axle under the trailer that already includes brakes and suspension?

Would that put it in a different license class for road use?

It has no lights and no registration at the moment. I rarely take it on the road. When I do, it's the back roads to a place less than 10 miles away. It has an SMV triangle on the back, but I'm sure it's still not legal, since it would be a real stretch to call it "farm use".

Not going to be cheap either way, but with axle replacement you have a chance to go with torsion (which I wouldn't, personally). I would increase axle to 5-7k with the appropriate springs, brakes and tires to increase the safety factor on your 3500 pound trailer. A used set might be a lot cheaper!

Yeah, you'll most likely need to buy an axle with the backing plate flanges. Or be skilled with a welder. The brakes have to bolt to something that isn't spinning.

Wish I had something like that to drag behind my chipper.

Tow it with the tractor, flashing lights and SMV sign on that too. You wouldn't go through all that bother if it wasn't really farm use now would you?

I'm not going to go 10 miles in my 13 MPH tractor to pick up a yard of stone.

The NH/Kubota dealer a few miles down the road used to sell these so easily he could not keep them in stock. Something like 10 years ago, they just stopped making them. When the dealer inquired, the manufacturer told him: "about the only place we sell many of them is in New Hampshire and Vermont. Just not enough volume to make it worth continuing production."

My existing axle does appear to have a place to bolt something on, so I might be able to add brakes relatively easily. The question is, do I want to do that to this axle, or try to find a heavier one with a suspension that already has brakes.

If I could find something used with a 5000# rating & with brakes and suspension, I'd jump on it. I'd consider new, if it weren't ridiculously expensive - I just haven't really started looking yet. I'm not sure how common something larger than a 3500# rating would be that is as short as this axle is.

Stone is heavy.

Suspension? Be sure the bump stops are substantial.

That would be the first hurtle. That could be a tough search. Here's some common sizes below. Also be aware that increasing the axle rating may lead to new trailer wheels and tires too.

No association. I just found the image on Amazon.

I was investigating for a utility trailer axle several years ago. At least one of the common manufacturers would build an axle to your specifications, including custom lengths. I also wanted one 4ft overall, including tires.
