JD 4600 or NHTC40D

Richard/Rat,

The 1705 lb. lift capacity(on the JD 4700/460 loader) is measured at the front-edge of the bucket.
The capacity measured at the pivot-pin is 2325 lbs.

Do you know how the Kubota and NH specs. are measured?

I was looking through my manual which covers the 430 and 460 loaders for Deere. I don't have the table right in front of me now but I believe that the breakout force specified is defined as the boom lift force at ground level, so this should not involve the bucket roll at all. JD gives boom lift specs at ground level (breakout force), at 1.5 meters height, and at full lift height. They also specify the bucket rollback and dump forces in a seperate section. Hope this helps.

I believe breakout force is the force developed by bucket curl be it a loader bucket or a backhoe. It is the reason it is so much higher then the lifting ability of the loader or hoe itself. The reason for it is mechanical advantage. Look at the roll cylinder and most of the time they are the same size or smaller then the lift cylinders in diameter. Look at the attachment points and the leverage comparison, the roll will have greater leverage. This breakout force is something I rely on almost everyday, Rat....

Gets confusing. Seems like it is just like any research, you can manipulate the statistics to say whatever you want. Unless you have multiple phd's in that field then it's impossible to tell who's really right.

Like I said before I don't have the manual with me right now but I do recall that there was also a graph which showed the lift capacity of the boom versus lift height. The lift capacity is greatest at ground level and drops off as the height increases. This make sense if you look at the angle that the lift cylinders attach to the boom. As the loader is raised the angle between the boom and cylinder decreases and thus the cylinder has less leverage on the boom. The specs that I saw showed much higher lift capacities at ground level and at 1.5 meters high than at full height. I will take another look at the manual when I get home and maybe scan in the page in question and post the results.

MJB,

The figures quoted in my 3/21 - 9:46pm post in this thread (and the one before it) are taken from the tables you are referring to.

Here is the promised page from the operators manual. You will note that the bucket rollback force at ground level is actually larger than the "breakout" force that is specified. Enjoy./w3tcompact/icons/smile.gif

Phil, I am tring to make the same decision as yours at the end of this week. When comparing "apples to apples" I am looking at price as well-the final prices for the JD4600 and L4610 from my local dealers are the same(within $25). True, the 4610 compares more equally with the 4700, but the 4700 is higher priced than the 4610-with my experience. The lift capacity is roughly 150#s more on the 4610-at pivot pin and the breakout force 500mm forward is slightly under 3000#s for JD4600, and Slightly over 3000#s for the 4610-Specs are basically the same for both models for FEL, but will almost 5 more hp on 4610 make a big difference? I am visiting both dealers 1 more time in the next two days and will decide and buy this weekend. Both dealers are great and have gone out of their way to help-it is a very tough decision.

Jeff...MI.

Jeff:
But it's fun, isn't it!! Pardon my ignorance, but the L4610 is Kubota? Just for fun, the following has been recently for sale in my area: Kubota 4200, 1997, 6 actual hours, R4, joystick loader, air-cond cab, power glide shuttle sync, paid 28,800, trade-in value about $16,000. What do you think?
