Loader Specs

[LD1]

Your 4047 is also about 1100lbs heavier than the R3039.

OR lets look at it this way, The R3039 is a full 1100lbs lighter, but has a loader that will lift just about as much as the 4047.

So the 3039 WITH ballast is going to behave more like your 4047 without ballast. So now imagine that light tractor, with 2250lb capacity loader, and no ballast:shocked:

I can imagine it: Scary! that's what it would be. Heck for fun, as soon as the L3400hst came off the truck I ran over to the gravel pile and scooped up a load of gravel, nothing on the 3pt and air in the tires.. talk about scaring the crap out of you! I just wanted to see what it would feel like, and it was BAD! I never thought that the L3400hst had a weak loader, It would easily lift the rears up nice and high in the air! Proper ballast is definitely called for! My Kioti is about 1100 lbs more than the Kubota, yet its loader only lifts about 200-300 lbs more. Now when you jump up to the DK40, with its huge KL401 loader it will lift 2700 lbs to full height at the pins yet it weigh's only about 100 lbs more than my tractor.. so you are back to SCARY! if you don't ballast properly..It is all about matching ballast to the tractor.

This is like the horsepower wars of the 1960's. "My SS Chevelle has more horsepower than your Dodge." "But my Dodge has more torque." Anyone remember those days? The tractor manufacturers can only do so much with engine horsepower, but loader specs are an easy and cheap place to play similar marketing games and build customer interest.

Not much of what I do with a loader is at max capacity; others can speak for themselves. Having a killer loader on a little tractor seems like an invitation for either eventual structural problems with the tractor or disaster in the hands of less experienced operators. Sort of like those '60's muscle cars in the hands of a teenager long ago! :steeringwheel:

Thanks for the replies/insights.

It does make sense to me that breakout force is a function of both boom lift and curl. The ratings published by each manufacturer are all over the place. There is no standard any where I could find. Deere literature provides more loader info than most and states a more realistic lift capacity is 500 mm ahead of the pin. Who knows? Too bad there is not a standard to compare apples to apples.

I also agree that ballast makes a big difference. What ever tractor I end up with will have ballast. I just don't know if I want to go with a ballast box or loaded tires. Either has advantages/disadvantages.

Since I'm mostly going to be moving brush, dirt, and eventually building some raised berms for landscaping on the land I'm clearing, I think any tractor in the 30 to 40 hp will exceed my needs.

On tractors of this size, loaded tires are good, but you still need something heavy on the 3PH if you are planning any heavy loader work. Loaded tires dont do anything to lessen the stress on the front axle. They actually increase the weight you "can" put on the front. Weight on the 3PH counterbalances the loader and takes weight off the front.

Loader specs are kind of like MPG ratings on cars. Good as a rough guide but need to be taken with a grain of salt. Plus if you add an option, like a roof rack the mileage will drop. The same holds true for loaders. Every MFG has their own way of coming up with numbers. On top of that if you add the skid steer quick attach option you loose lifting capacity yet MFGs don't include those numbers.

+1 on loaded tires AND 3pt ballast, for the reasons LD1 mentioned, and when you have the 3pt ballast off and your rotary cutter on the 3pt and you are cutting on less than flat ground the loaded tires help lower your center of gravity to keep your shiny side up. But the loaded tires won't do a thing for "unloading" your front axle like the 3pt ballast will.

+2 on loaded tires AND 3PT ballast. Traction is another advantage of loaded tires. I lost the fill in one of my rear tires. Never had it refilled after the repair. It is ALWAYS the first one to spin.

You know I just don't know how a manufacturer can determine a lift capacity at the pins, juts how would you calculate that know one ever lifted anything at the pins that is halfway back the tractor. Another questions is how do so many different manufacturers have different at pin numbers when many or maybe most loaders are made at the same place. Now bear with me here I am not trying to start a war here or a mine is yours is thing but aside from Kubota many manufactures use loaders or equipment manufactured by Amerequip. Look at their site here Design, Engineering and Manufacturing Solutions for OEMs, and Custom Equipment, Tractor Attachments and Backhoes - Amerequip (ARPS) they make equipment for many different manufactures that have been mentioned here with different listed ratings, here is their client list from there site

Now of course they probably don't make every size of loader that each of these companies have by who knows and they probably make them different but there shouldn't be that large of a difference. Oh well just a thought I have wondered this for a while.

I'm not even close to having any mechanical engineer background, but.......the variations could be due to the design and target buyer by the manufacturer. It seems to me that the geometry of the hard parts, the size of the hydraulics etc. could produce some variation in rating even if there was some "standard". The design/dimensions of the tractor could create some geometry differances. The manufacturer probably targets the use his buyer would expect. Thus the differances.
Just a thought.
