840 John Deere Loader

Anyone have an 840 Deere loader? Need to know what the lift capacity on one is and how much more durable it is than a 740.

Lift capacity will largely depend on the tractor you have it on. A 50 series can't lift as much as a new 8030 series tractor. The hyd. systems on the older tractors isn't quite as good as on the new ones. The newer tractors have more gpm (30 plus vs. maybe 15-25) on the pumps and higher psi (2900 vs 2250).

Specs for the new 843 loader (couldn't find anything on the 840, should be close to the same)- http://www.deere.com/specsapp/Custom...FR&pNbr=0843XW

740- http://www.deere.com/specsapp/Custom...FR&pNbr=0740XW

OK Thanks. Will a 55 series tractor have more GPM than the 50 series?

Maybe. Can't really say. They are pretty much the same tractor. Just metric hardware.

The brochures I have on the 55 and 60 series tractors say-

40-4455 has a 8 piston variable displacement pump. 3 cu. in. (50 cc) and rated @ 2530 psi.
45-4955 and 45-4960 are 4 cu. in. (65cc), rated @ 2530psi.

IF I ran the numbers right, we are looking at 22 gal/min for the smaller pump, and 30 gal/min on the big one. If my numbers are wrong, hopefully someone who knows different will chime in.

8000 series are 30 gal/min @ 2900psi.

*** edit***

As luck would have it, I found specs on the 740. The 725 has a slightly higher lift capacity @ 4100-4700# on the 7200-7800 tractors. 740 was 3800-4000# on the same tractors.

I'm kinda tossing the idea around of a 4555 with an 840 and was hoping it would lift a 5500-6000lb 13' tire tank.

Sounds like you need a forklift or wheel loader.

I knew somone who had one. He used *** for loading trucks His complaint was w/it fully raised to clear the truck was it "didnt stick out far enough out in front". Ie you had to get too close to the truck to dump in the center or far side. I think tractor wise esp if you put it on a 4850 w/duals the tractor will be plenty stable to pick up taht weight *ie you wont pick the back up), but will the frame and loader do it esp daily, when its cold etc pry not.

1996 Gmc k2500 4x4 6.5 turbo diesel, with mods Blew the head gasket, put all new heads, valves, injecotrs gaskets etc on the truck only to get it together and find out it had no oil pressure, and sounded horrible (pry a spun bearing). SOLD

Yeah, but they can't do anything but handle loads and we need a 140+HP MFWD anyway and I don't like having another piece of equipment sitting around that need maintance if I don't have to.

We have a regular forklift mast, and have it converted to use on the 3pt hitch. Will need at least a full rack of suitcase weights up front, though. Especially with that much weight. If you have to lift it very high, you'll NEED to put the duals on for stability reasons. The singles can get squishy and squirrelly on you.

Just need to find a mast with the capacity to lift it and not bend the forks.

A 4555 should be just fine. It has the same axle dia. as a 4955, and the same lift capacity as the 4755 (9411#). The 4955 can lift 10.6k. The bigger 102gal fuel tank will give you more ballast than the 65 gal. tank.

Another question. Does the 726 only fit 2wd tractors? It has a lot higher capacity but I can't find any pic's of it on a MFWD tractor and all the ratings are shown on 2wd front tires :shrug: .
