TnT: Kubo ata's vs Integration Engineering, Part 2

Madreferee,

Thanks. I'm pleased with it in the end.

What may appear to be valve bodies above the sidelink are actually heavy, cast Kubota quick connect holders. Hoses connect these to the Kubota SVC valves under the seat. Only IE's cylinders and hoses in this setup.

Henro,

This tractor definitely needed check valves, right out of the box. As far as extra cost, IE's piloted were less than Kubota's plain cylinders. But yeah, if you shop around, that may not be the case.

Bill, I guess I'm still trying to figure out the what, wheres and why's. I realize that if you have the option of a piloted check valve vs not it may be the wise choice, but I fail to understand when a slight amount of drift would ever be that critical. I change the cutting angle on my box blade with every pass. My mower is not critical of any drift, my Harley rake could really careless if the top link extended an 1" much less about 1/64" in many minutes of use. Speaking of Harley rake, I need all the power of my larger top link cylinder to pull it in. I can not think of an instance where I would benefit from a piloted check valve, can you?

John, in looking at your setup, I notice the tilt cylinder is also smaller. Do you have any issues being able to lift? I know with my 1000lb box scraper, I pretty much need all the lift ability the Gannon cylinder has to offer. The setup you have is nice and clean, good job.

RaT,

I guess it is a matter of how much drift one experiences. Just like loader control valves, one guy will have a loader that stays in the air for days on end if left in the air when the tractor is parked, and the next guy will have one than drops a foot in an hour.

I think if my top link drifted fast, it would be a pain with the box blade as the cutting angle would be constantly changing. If the tilt cylinder drifted...again relatively fast, the angle would be changing.

If the drift were very slight it would not matter at all most likely.

When brush hogging a large field, which I don't have, unfortunately, I guess it could be inconvient if the tilt cylinder kept changing length, and the BH kept tilting.

I guess it all depends... /forums/images/graemlins/shocked.gif

Rat,

Thanks.

In your case, the sidelink only has to lift half the weight or 500 lbs. If your system is 2000 psi or more, thats only 1/4 square inch of piston area required to lift 500 lbs. Maybe you're hearing the hydraulics strain against a flow restrictor?

Re: TnT: Kubo ata\'s vs Integration Engineering, Part 2

Rat . Thanks for your input ! I was worried about "cylinder drift " . But I went with cylinders without "pilot valves "( Kubota) .
I have yet to experience any kind of problem with the tnt cylinders changing settings . I think that the pilot valve thing is much overstated. John

Re: TnT: Kubo ata\'s vs Integration Engineering, Part 2

I have the factory TnT on my L 4330 and the only thing I do not like are the quick connects; they leak oil every time they are disconnected.

Re: TnT: Kubo ata\'s vs Integration Engineering, Part 2

That is the nature of quick disconnects... they always will leak a small amount of oil when you disconnect them. Just as long as they don't continue to leak after they are disconnected, they are fine. I had one on my tractor that had a continual drip and it was replaced under the 1 year loader warranty. No other problems since...

Rat,
You might want to have your hydraulic system checked when the unit is hot. Kubota does not list their working pressure for the exterior hydraulics but it should be around 2000 PSI. At 2000 PSI a 50MM cylinder like the IE system uses should have enough force to lift anything the tractor is safely capable of lifting. Remember that the hydraulics function properly when the engine is running close to the 540 RPM mark on the tractors tachometer. Since you have a larger cylinder you have even more force. Maybe the relief for the rear couplers was not properly set or you may have some other hydraulic system issues going on.
