3pt not lifting to full capactity

[Tim_in_IA]

Just got an email from the dealer that they were ordering a part to fix it. I am assuming it is the relief valve but they didn't say. That's what the mechanic said he was going to test a couple hours ago.

Yup, just got another email... it was the relief valve.

Looks like it will be an easy fix.

Now will it be easy to give up the loaner?

Tim,
If you have a picture of your hay spear could you post it? I would like to see how it is made. Part of the description makes sense and some of it doesn't.

 

[Tim_in_IA]

Sure thing I will post a picture this weekend.

I was on the Mahindra site and it looks like it has had a facelift. Found the link to this movie. The bales look just like mine and exactly what I want to do! Can't wait to make it happen, but like my grandpa said, I guess I will (wait that is ).

Here is the movie if anyone wants to watch

I also would like to see a pic of this hay spear. One thing I found out early on, hydraulics are rated at different points, and a little leverage on either side of that point can make a BIG difference in how "stout" they are. But you are right, that 6500 should have no problem w/ that size bale. We put up 5x6 at about 1400# and my 5005 has to grunt a bit, but it will do one on the 3pt spear and one on the FEL.

As promised here are the pictures of the bale spear....

Tim,
Wow, never seen one made like that. After seeing the spear, I think that it is the problem. You are in essence lengthening your lift arms with that type of spear. By doing that you aren't using any of the mechanical advantage of your three point hitch. Cut off the butt section and weld up an "A" frame. It would be a lot less expensive than buying a new one all together.

Jerry,

Yeah I think I am sold on getting a different one. This is actually my dads and I don't want to modify. I've seen them around for a few hundred bucks, and I am sure I would have more in it to have the machine shop refab. Plus it would be nice to have a higher spear to keep the bale from wandering side to side. The low pickup with these isn't ideal either. I am still trying to grasp why connecting the toplink changes the lifting power so if you have any links or info that describes the relationship I would love to look at it.

These were my grandpas spears before they were my dads and were actually fitted with fast hitch adapters when I saw them. They screamed three point though with the ball connectors. They were probably intended for a much smaller bale. I'll look around to see what I can find for a new spear. My tractor dealer recommended a good local welder that makes his own stuff so that might be more reasonable. Might get one for the front while I am at it.

I saw a place on the net somewhere that showed diagrams with explanations, but don't remember which site it was. If you want to do a search, I think that it was an old Ferguson site.

 

[hudr]

That thing looks like a leverage nightmare. A simple 3pt spear should be pretty inexpensive. One for the FEL would definitely be handy. Especially if you plan to load a trailer w/ round bales.

The bale spear that I am using is an older vermeer with 2 spears. It only attaches to the bottom links and has stops and chains that exert the force against the bottom links. Would this have less capacity than a spear that utilized the top link? I didn't think so before since all the power comes from the bottom links, but if there is a lever action that happens this also might be contributing to the issue.

The 7520 loaner lifted the bales fine with the attachment but it has a rating almost 1000lbs higher.

Tim, sorry I somehow missed the last posts on this thread. YES, this arrangement - the one you posted pictures of - loses lift capacity as you move out from the balls. If you were to measure the length of your lift arms (A), and then measure the distance from where the lift arm pivots on the tractor to the "point" on the spears where the weight is being lifted (B), you could have a good idea of what to expect. The lift caacity will be A/B times the lift capacity at the balls. From the pictures Im guessing the fraction A/B is about 1/2. I just had to look back to the 1st to see how heavy those bales are - - I expected about 1Klb which wouldnt have explained it. But 1800 puts it very much into the iffy zone. I imagine your tractor is ok, but while youve got their attention get the mechanic to set your pump relief pressure to to high side of the spec. Springs lose a little bit of their tension during breakin for various reasons. This effect on hydraulic relief pressure is very small unless the seat actually wears. What isnt quite so small is the effect of heat. The spring is a little weaker while warm. The difference in relief pressure may go down 50psi (a percent or 2) in a hot system. This should be allowed for during adjustments made cold. If you can get them to show you where the adjustment is made please let us know.

Galen,


I keep thinking of Mahindra's commercial today where they are picking up 2 tractors from competing brands with a mahindra. That is really selling me the message that this should be no problem lifting a bale. If that is not the case then I'd like a word with their advertising department.

For the commercial you are referring to, we did lift the competitors' tractors numerous times.

Without your top link connected to your hay fork, you will not be able to lift your bale. I believe using a hay fork that connects to the three-point hitch (top link and lower link arms) will solve your problem.

 

[Tim_in_IA]

Thanks for all the input guys! I will definitely be getting a spear with the toplink component. I am actually glad it happened though as my relief valve was faulty. Great to find out now instead of later. Time to go attachment shopping!!

 

[Tim_in_IA]

I have the tractor back but I haven't found a good spear that incorporates the toplink to check the bales out on. I had my pallet forks on yesterday and I was backing up with about a 400lb load and the 3point just dropped to the ground. I moved the lever forward and back a bit and it came right back up. Could this have been an air bubble or something more serious? As a recap I just had the relief valve replaced.

 

[Tim_in_IA]

Just thought I would post an update. After getting the relief valve replaced I purchased the king kutter E-511 bale carrier and I moved 2 large bales over the weekend.

 

[Bob_Skurka]

I moved 2 large bales over the weekend.

Wow Tim, 1 bale a day. Did you break a sweat too?

BTW, an this time I'm serious, how is your dog? I lost track of that thread and can't seem to find it.

 

[Tim_in_IA]

Bob_Skurka,

Yeah, I am trying to squeaze in some late fall hay making and I just picked up a couple hesston pt10 mower conditioners. They both have their peculiarities and we got around the field 3 1/2 times and a belt broke. We've had rain on and off so I decided just to bale what I had down and fix the mower and try again if weather permits. Translated to 2 bales.

Maybe we'll have an Indian Summer or whatever and I'll get some more. Gotta love used equipment!

My pup is doing great! You can hardly tell except his neck is still a little bigger than normal and the bite marks never grew hair back. For some reason the moderators moved that thread to the rural living list. I guess rattlesnakes don't have anything to do with safety but aligators do Go figure. Thanks for checking in on me.

 

[Bob_Skurka]

Glad to hear the dog is doing well.

We are getting the same wet weather you are (except we get it about a day later than you). But it is on-and-off rain here too.

I have a 4005. Recently I have noticed that the hydraulics seem to be operating slowly. Also, if I have a heavy load on the three point hitch the loader moves very slow or may not lift a moderate load at all. I have made sure the speed control is turned all the way to fast. I have changed the hydraulic fluid and filter. Can this be air in the line or is the hydraulic pump going bad.

Remove the stop bracket on your 3ph speed control and close the speed control all the way. Then with the tractor at an idle put your 3ph lever all the way up and down a few times. When you are in the up position you will here a squeal which is the bypass valve opening. Maybe you have some trash stuck in the bypass valve and this will clean it out. Put the 3ph speed control back the way it should be and put the stop bracket back. Also put the loader all the way up or down and give the joy stick a couple of bumps to clean out the pypass on the loader valve. If this doesn't solve the problem some pressure and flow testing will have to be done on the hydraulic system. It's probably best to take it to your dealer for this. Good luck and let me know if this solves your problem.
