JD 350b weights

Post by zebqup » Thu Jun 25, 2020 7:23 pm

I bought a nice JD 350B track loader. It has a modified 4in1 bucket off a JD450. Its wider, taller and much heaver than the stock bucket although the machine seems to handle it fine. My problem is that the total unit weight is too heavy to get up the road to my forestry property. My 1 ton 4x4 just spun out. It also has weights on the drive sprocket and suitcase weights on the back. I am wondering how much weight I could off load by stripping this stuff off for transport. I can't find any info on the weight of the bucket or counter weights. Just looking for approximate weights before I go through the trouble of tearing it down. I was able to off load the loader and walk it up the hill but it blocked traffic and it was sitting at a steep angle. Its not something I want to repeat and its not in a convenient location to work on now.

On a related note. I would like to fab a quick disconnect system for the buckets so I don't have to line up and hammer out pins every time . Kind of like a skid steer. Has anyone here done that?

I would guess at 6- 6 1/2 tons.

Have you weighed your machine to know where you are starting from? Bumper pull or gooseneck trailer?

Bucket weight I'd guess at being in the 1500 pound range. Counterweights would be hard to tell. You said they are suitcase weights (these would be like the ones used on the front of wheel tractors by my definition of suitcase weight), not usually on the rear of JD crawlers. Take one of and weigh it, multiply the number of weight for the total. Otherwise figure out the cubic inches of weights and any support frame you have, rear and sprocket. Steel is about 0.29 pound/cubic inch, cast iron is about 0.26 pounds/cubic inch. Estimating weights this way is common practice for rigging projects. The John Deere 355D loader info sheet (on their non-current models site) shows 12,400 pounds as operating weight with ROPS, standard bucket, and base counterweight. Do you have a ROPS? I will guess I will guess 9,000 to 10,000 pounds is about the lightest you will get your 350B by removing the bucket and counterweights.

As for quick attach for the bucket you need to be looking at the quick attach systems for large skid steers or 1 to 1-1/2 yard articulated wheel loaders, much heavier than skid steer quick attachments. You need a system that meets or exceeds your 350B bucket breakout force, and the 4 in 1 will see forces not seen by a regular bucket.

Just my thoughts.

Whatever weights you can take off will not be a big factor in going up the hill. Seems to me traction is the issue, not weight so to speak. Even if you could get 1500lbs off the tail, is that really enough lighter to make a difference. I would load the crawler farther ahead to get more traction on the pickup.

I agree with Lavoy here. Your counter weights will not make enough difference to make your truck pull. We hauled Deere 450's and 550's behind Ford F550 Super Duty's on goose neck trailers all the time. Not sure what kind of trailer you're using but sounds like you have your machine too far back and its lifting the back of your truck. If you can, move it forward until you have some of the weight on the truck itself.

Your total machine weight will be somewhere around the ten to twelve thousand pound range. Your outboard sprocket weights are about 250 pounds each and the bottom center or skid pan weight is about 500 pounds. I don't know what kind of suitcase weights you have but Ag weights are normally around 100 pounds each. So, as Lavoy pointed out, you won't gain enough to make any difference by removing all this added weight.

Our B model with sprocket weights, and belly weight weights 12,250lbs. Add for 4 in 1 and extra weights, but still a positioning issue I feel. If I load forward enough on my trailer, like when I put two crawlers on, I can't imagine that I could hardly spin out in 2 wheel drive let alone 4 wheel drive.

Thanks for the good advice. I submitted one reply already but it didn't post so this may be a duplicate. I did find some numbers on the counter weights and the suggested weight is 800# and 9 to 12 hundred pounds for the bucket. I do load the loader as far forward as is safe on the trailer. I have pulled a 10,000 pound crawler up that road (more of a Cat trail) for years. Think I will load the Bucket on the truck and re-rock the road next time.

Excellent suggestion comparing breakout force for a comparable Skidsteer attachment. I am already taking measurements to Fab it.

Is the machine loaded bucket forward or bucket to the back??

I load it bucket forward and it is a bumper pull hitch.

To address the traction issue, I would try loading with the bucket towards the rear of the trailer. Even with the heavier 4 in 1, I believe the center mass is towards the rear of the track loader.

Measure the bumper height, load the machine on forward and measure again. Then, load it on backwards and measure . The lower the bumper--the more traction.
