LA 703 Loader

jsborn · Jan 23, 2009

Does anyone have a PDF file of the parts list or the owners manual for the Kubota LA 703 including the Joystick. I know I could probably buy one but I am thrifty (cheap) and hope to find one I can download.

I have attached a copy of the parts manual. Hope it helps. How do you like your loader? Is it on a L4400?

jsborn · Jan 23, 2009

Thanks Dex That is just what i was looking for . I have had my loader for 3 yrs on my L4400 with no problems. Like every thing it is too weak for some things but I always end up pushing the limits of my equip. I am not unhappy with it I just always want bigger fast less expensive ....

Have you ever considered turning you curl cyl end to end to increase the breakout force ? They seem to me to have the rod side of the cyl doing the breakout which would be less force than the no rod side ? I may be looking at it wrong but it might be something to consider??

Thanks again for the parts list

Have you ever checked your pressure on your hydraulics? I dont have much of a lift problem but I am not happy with how far it rolls back. May change it after the warranty.

Yes Pressure is per spec and it works ok I just think it might have more break out force if the cyl were turned around. You know some people are always tring to improve stuff

.. How are you considering changing the roll back ?

dex3361 · Jan 23, 2009

I will retrofit the multipoint linkage like on the grand Lxx40 loaders. Check out the loader break out and the rollback angle specs on the Grand Lxx40Loaders. I dont think swapping your cylinder will help on the breakout force. When you are curling back with the cylinder either way it will be retracting (which is weaker than extending).

You are 100% correct it will not change a thing.

I dont know why I thought it would but now that I look and actually think about it it wont . Oh well I will look at the grand L loaders when i can thanks for the info again.

Buy larger diameter cylinders if you want more force. (and possible breakage...)

Dex3361 hello! I have a L4400HST with LA703 loader purchased in Nov. 08. That a great parts manual for the loader. Do you have any info. on the tractor itself showing parts etc?
The L4400HST is a great tractor...first one I've ever owned. I'm looking forward to many projects. So's my wife, can't keep her off it! Thanks for the help, Mike.

Almost forgot--What can you tell me about Top and Tilt for the L4400.

You might try kubotabooks.com not sure if parts manual for that tractor is listed but they have several. You can also go to tractorsmart.com and fill out a request and they will email a link to the manuals you are requesting.

Thanks, I'll check it out. I've already tried a few internet searches and found very little on the L4400 with HST. Some stuff on the L4400 gear drive, but that's not what I have.

Here it is as an attachment. I agree with John Bud you have to be careful in what you change it can lead to bending or breaking something. If you have checked your pressure then it is to spec and that is the design strength but alot of people are finding that the pressure is low and bringing it to spec will help. The pressure is supposed to be about 2600PSI and to change you add shims to the pressure reg at about 37psi per .001" added.

The Top and Tilt replaces your top link and your adjustable lower lift arm on the bottom with hydraulic cylinders. These cylinders are operated by remote hydraulic ports (2 ports operates 1 dual action cylinder, 4 ports operate 2 dual action cylinders, etc) so a top and tilt would require 2 hydralic rear remotes(4 ports). With Top and Tilt you have the ability to adjust the cylindersfrom the seat.

The Parts manual is to big to download so I will try to add it to the Index of Kubota books web site. Index of Kubotabooks/

I purchased L4400 with LA703 loader that the dealership sold me to unload rolls of hay from trailer and move to barn etc. They even sold me the hay forks to go on front end. This tractor won't even lift the rolls off the ground with front forks or back forks. Very dissapointed in this tractor.:

You need to have the relief pressure checked on the FEL. I checked mine and found it was low. Bumped the pressure up to spec and it was good to go. You should be able to lift about 1400# depending on how it is positioned.

The 703 loader is ok but about 1400-1500 lbs is it. The LA853 Is just about as strong as my TL1000 in my opinion, if not in the lift, the curl force is about the same.

P.S. You can cheat about 5% on the pressure setting without undue strain on pump or engine, but don't go overboard.

Thats why if I were to buy today I would seriously consider the MX5100 or the MX4700.

While I dont doubt you... I am wondering if there might be something wrong with your tractor... I have an L4400 GST with 703 loader... It routinely picks up 5x6 round bales of coastal grass.. I DID have to build a weight box for the rear end due to not loading the tires...

Do you know how much the bales weigh?

Gloria Petty · Jun 7, 2012

Thanks to all who told me about pressure. The dealership we bought from sent their "service manager" out who looked at the bales and said this tractor would never pick up the bales(1000#-1200#). After discussion on this site, we contacted another dealer and was told about the little knob under the seat. So I think we have solved problem on lifting bales. Interested in weight box you built for back end.
