Loader G3033 Actual FEL Lift Capability

[k0ua]

So I borrowed an old 3-pt back blade and retried my test.

So the water adds up to about 1,050 lb (125 gal) and the tractor is completely stable now that it has the rear weight from the blade. But the FEL won't lift the load any higher than you see in the picture. It just stops lifting. I couldn't even put the pallet on my flat bed trailer.

I dumped 160 lb off and I was able to lift the load as high as I wanted to. That put the weight about 870-900 lb.

So I guess the G3033 can lift 900 lb. And it's rated for 1600 lb at the pin. I'm a little disappointed but glad I know now.

I might still get the tires filled with Rim Guard but it seems that a 3pt mounted ballast gives me what I need for stability.

Any last thoughts? Do you think it can lift more? If so, how?

Buy a pressure gauge with fittings (30 to 40 bucks) find out the max pressure of the relief valve in the workshop manual, ask to have it looked up if you ca nt find it online, and shim the relief valve if it is set lower than the manual calls for. Many tractors come with the relief set too low and I suspect yours is. I could also be wrong but I think yours is low.

Here is why I think that the relief is low. I can lift 1000 to full height on a pallet with my forks. My loader is rated at 1430 at the pins. I haven't tried any more than the 1000.

You're forgetting some very important factors.

First, the weight of the pallet forks... Probably 250-400 lbs depending on the forks.

Second, when you extend the weight away from the tractor, such as on forks, it dramatically decreases the lifting leverage of the machine, and in turn, causes the same weight to act heavier.

Hold a 50lb weight close to your belly, then try holding it with your arms fully extended... same amount of weight, but your decreased leverage causes it to act heavier.

Sooooooo ... Don't confuse the measured "rated weight at pivot pins" with weight on pallet forks. It will be a drastically different measurement.

I'd guess your relief valve is set low. My tractor has a similar lift capacity and can load 1000 pound pallets on a flat bed no problem.

I understand the lift at the pivot pin does not represent the lift capacity at the end of the forks. I never expected the tractor to lift the 1600 lb. I was just hoping for more than 900 lb.

Thank you for the advice on the relief valve possibly being set too low. If I buy a gauge, where do I hook it up?

It does not matter all that much, You can take off one of your quick connect hoses on the loader control valve work ports and actuate the proper lever position to take a reading. You are basicly "deadheading" into the gauge, and the relief valve will open and allow excessive pressure to go over the relief valve. Look at your reading, and go from there. Be sure and NOT use ordinary standard plumbing fittings, Use only fitting designed and rated for hydraulic pressures. Most plumbing fittings are rated for 300 lbs.

You can find the gauge and fittings at surplus center and make one up yourself or Kenny can make up one for you if you want to buy it premade.

?

I hear what you're saying, but don't forget to add the weight of the forks too. Let's assume they weigh in at 300 lbs. That moves your weight up to 1200 lbs.
