    why does using FEL stop Power Beyond flow

    Correct, totally get that. the moments where a cylinder is bottoming out and the OP valve would activate are a tiny fraction of the entire cycle of operating the system; so this is more functional for my use just considering the grapple use. However, it gets even more important if I am able to...

    why does using FEL stop Power Beyond flow

    I do appreciate the replies, but no offense, but this is a pretty standard non-answer. Closed center is superior to open center in just about every way except cost. Which is why us small-tractor owners are stuck with it; manufacturers have more incentive to hit a price point, and even for...

    quick-couplers - when are iso-5675 compatible with iso-7241-1 (A?)

    what I'm taking from this is the same as I came in with :) 1/2" will probably most likely work, but it may (will?) not be optimal. Ok, so having a small tractor I don't want to loose any more pressure drop than I need - there aren't that many fittings should I replace some. what fitting flows...

    why does using FEL stop Power Beyond flow

    the example with gravity is a good one, except for the fact that the "bad" condition there is user-choice. If speed of movement on that one cylinder is the user's priority, then they would not operate a downstream function (because, as you say, the "backpressure" would interfere with their...

    Can a pile of fresh wood chips spontaneously combust?

    our fresh piles of wood chips, one large utility truck's worth (maybe 5'tall, 8'wide, 12' long) would smoke, and be uncomfortably hot inside. This in a mild climate, with plenty of water, and never covered. I don't think you'd need too many variables 'worse' to get ignition: significantly...

    quick-couplers - when are iso-5675 compatible with iso-7241-1 (A?)

    a few sources, including the Summit spec sheet, seem to indicate that it's not always a ball ... does this track your experience, or should all AG/5675 connectors use a ball?

    Posthole Digger Best Value Compact 35hp 3-Pt PHD?

    slightly smaller tractor than you (but I only bought the 2610 to avoid tier4 ...) most of my implements are brand names, but for the PHD I did go tractor-supply / country line https://www.tractorsupply.com/tsc/product/countyline-3-point-post-hole-digger-602377 I've been happy with it. My soil...

    bucket tooth bar: EA wicked root ("continuous tooth") vs standard tooth design

    Trying to make sure i understand how this is different/better than a box blade: If you are not using the "reverse direction scraping" feature (I wouldn't either, that seems marginal unless you have a really tight space; even then, FEL + float?) so the only difference (if you use...

    bucket tooth bar: EA wicked root ("continuous tooth") vs standard tooth design

    So the ROBB does forward-scraper and reverse scraper ... but in scarifier mode the tines are behind the blade?

    Controlling A Hydraulic Solenoid valve With PWM

    Here's an analogy that is surprisingly accurate. Stand at a teatherball pole, hit the ball repeatedly, trying to keep it, smoothly, at a specific height/distance from pole (straight out, not in a circle) Small, well timed taps of the appropriate force... if you could tap VERY fast, you could...

    Controlling A Hydraulic Solenoid valve With PWM

    That is 100% correct. The input is digitial (pulses; anywhere from 100's to megahertz depending on app/industry - idk what hydraulic proportional valves use, kHz would be common in general) The output is a "transfer function" (systems speak)**, which quantifies how a particular input will...

    Controlling A Hydraulic Solenoid valve With PWM

    Turbo comes from the old days when plenty of software (especially games, but also office sw) was coded with certain expectations of the processor's specific clock rate. The "turbo" button just made the cpu run at its actual full speed, which "non turbo" essentially a compatibility mode. or...

    bucket tooth bar: EA wicked root ("continuous tooth") vs standard tooth design

    What are ROBB (_ _ box blade?), LPGS?

    D03 valve -vs- manifold flow rates, and series flow route

    Thank you; that confirms how i was thinking about the flow, and would be an improvement over the existing remotes + additional remote/grapple The biggest sticking point now is size - D03 fits great, D05 is nearly twice the size :( which would be tough. I guess all the off the shelf versions i...
