Trailering a JD 4120

[whitedogone]

I have a 4120 that I need a trailer for. I mostly haul from farm to farm (about 7 miles). But maybe once a year pull about 80 miles one way to the house. I'm wondering if a #7000 trailer will do. Here's my setup:

1/2 ton Chevy Z71
JD 4120
400X loader W/ bucket or grapple (#400)
Rimguard About 100 gallons
Bushhog 276 (on short hauls) #900

You should have a 10k trailer about 20' long, this will typically haul around 7,500 to 7,900 lb payload. This is for light trailers.

A tilt bed trailer will weigh more so it will haul less payload, typically a 10k tiltbed will haul 7,000 lbs or less.

I use a 12k Pipe trailer which weighs about 2,600 lbs and has a payload capacity of 9,400 lbs. This allows me to move my 110tlb or either of the tractors with implements. I can pull this with either my F250 pickup or my F550 trucks. I use a Class V (5) hitch on my F 550 trucks so that everything has a safety margin.

I'd expect you w/ bushog to be at a minimum, 1000 lbs. overweight on a 7000lb. trailer. I've got a 16' tandem axle (brakes one axle) landscape trailer, but I use a friend's gooseneck for the 4120 here. Even if my 16' trailer would stand the weight, it's not long enough to balance the load well - and that's with nothing on the rear.

I have a 10K gvw that handles the 4520 with attachments just fine. It has brakes on both axles and has not posed any problems. At 18ft, I have to put the bucket up on the front rail if I have the bush hog on. 20-22 ft would have been better, but I bought it back when I had the 4300.

I'd say you're VERY light on the est. wt. of the loader, 400# probably won't even cover the wt. of the grapple, much less the loader and subframe. That setup (tractor, FEL & bush hog) should weigh very near 7K. An average 10K 20' trailer will weigh around 2500#, so at a minimum you need a 10K trailer to haul that tractor. Allowing for ~10% tongue wt, you will have about a 1K safety margin with a 10K trailer.

Even without the FEL & bush hog, a 7K would be barely adequate for your 4120.

I used JD's ballast calculator to get the exact weights on your stuff. I guessed you had an open station with R4's, and that your R'4s were 80% full. It calculated your tractor and your equipment at 6,854 pounds with what you listed.

#400 is the weight of the grapple by itself. I figure it's the heavist of the bucket or forks or grapple.

OS, R4's, with right at 100 gallons of Rimguard

Again, The max weight will only be on the farm to farm trips. I never haul the 6'bush hog home.

A 7K trailer that is well built will handle it but is on the margin of safety...

I used to do exactly what you are describing minus the rimguard up to 70 miles and never had any problems but very soon learned I should get a 14K gooseneck and 3/4 ton truck for my application. It can be done but is risky. Not sure what the law enforcement is like in your area but I had a friend get pulled over by ISP and they fined him over $1500 for having a bobcat on a light trailer and he was really close to being legal...

 

[Baucom]

The difference in you hauling "exactly" what the OP describes on a 7K trailer, minus the rimguard, is that the OP has ~1000#s of rimguard in his tires that you didn't, pushing him over the edge from barely safe to 900# overloaded on a 7K trailer. He will need to put about 900# tongue wt. on the truck to get the axles down to 7K in order to haul w/o the bush hog (make it 1800# tongue wt. with the bush hog). Even then, pushing equipment to its max. isn't a good recipe for durability. In the length the OP needs, a 10K trailer isn't that much more money than a 7K, especially when factored over the life of a trailer.

Lots of good talk about the trailer, I'm concerned about the truck. Suspect this would be at the limit of things for a 1/2 ton.

It's real close with a 7000# trailer and the load
