Buying Advice Quarter-inching Valve

[davatk]

Yes I believe the quarter inch valve setup is total junk. There is no excuse for a tractor with a 3 pt hitch to not have position control. I honestly didn't understand the quarter inching valve when I bought my tractor (B3200). If I had known what the 1/4 inch really was I would NOT have bought a tractor with it. It was unimaginable to me for a tractor to not have a "position control" setup on it, and I thought that the 1/4 inch was some sort of improvement or addition feature to the standard position control type that every tractor I had ever ran had. **** my 50 year old Farmall has "position contro"l. Shame on me for not knowing exactly what I was buying I suppose.

Junk, Junk, Junk.

Well, I wouldn't go quite that far, just that I haven't really seen the adavantage (if there is one) to having a QI valve. Maybe there is one, or maybe the QI valve is just cheaper.

I have two machines with the QI valve and bought them only because there was no alternative in the size. If at all possible, I will never buy another regardless of the cost.

I think that's basically it... considerably less cost.

I vaguely recall someone making a case once for a scenario where the QIV had an advantage, and it seemed reasonable at the time, but it's long escaped me what it was.

But for the most part, PCV says to QIV: "Anything you can do, I can do better."

I don't believe that quarter inching control systems are that much less expensive to install in the factory than the position control. My suspicion is that Kubota handcuffs the B series basic models to force buyers to upgrade to higher cost tractors. Kioti and Mahindra have position control on all their tractors even the 20hp entry level machines.

Thanks! That is very good to know. I can only base my experience with those on the 7520. It has very nice, well controlled action which does not seem to vary with engine speed. This is in contrast to the position contolled 3ph on the Kub L3450 which moves up proportional to engine speed. With a heavy implement at hi revs itll bounce the front wheels in a lift even with the loader.

Out of all the SubCUTs available, there is one that offers position control - the Cub Cadet-Yanmar Sc2400 and Sc2450. I really have to give them a thumbs up for stepping outside the box in that segment.

Maybe that will serve as impetus for oters to follow. The Cub Cadet dealer in my area is not somewhere I would buy from.

You might want to get the 3450 looked at by a professional as the hitch is not supposed to work like that, but then again if you are overloading it enought to jump the front tires off the ground with a loader on it, maybe it wasn't supposed to lift that much!

It seems to me that the quarter inching might be useful when mounting an implement. Positional control, if it works as advertised, is pretty neat if you are using a ground engagement implement. If it really releases the implement as you go too deep and start to bog, it would really be a help when plowing or using a disc harrow. I have never had a tractor with positional control until my new L3700 is delivered so I can only speculate. I know that plowing was a real bear with my b5200 without that feature. Never tried plowing or disking with my BXs because my plow and disk harrow are too big for them.

A B-5200 has position control not a quarter inching valve!!!!!!!

Oh, its well within the lift capacity - roughly 60%. The spasticity does bother me a lot since the load accelerates quickly to match pump delivery to the lift cylinder. At high revs this amounts to hitting system relief pressure for an instant on each 3ph adjustment. Are you, :anyone: familiar with the 3450 and know that it has a system feature that should prevent this?
Thanks, larry
