    Moving from 1/2 ton truck to HD truck

    We have a 2018 GMC Terrain Diesel, it's the only year they offered the vehicle with the 1.6. Horsepower is listed at 137 hp or something like that. It's anemic on paper. But real world driving, it feels more powerful than the 250 hp gas turbo model, and doesn't hunt gears near as much. If you...

    Moving from 1/2 ton truck to HD truck

    Lot more to towing than straight forward acceleration at full throttle. That is all your spreadsheet will show, and even then, you are assuming full HP at all times, which is not the case. I believe one of the reasons towing with a diesel is so nice is that the torque curve is low. Even if the...

    Sawmill Trailer build

    Huh, I haven't noticed most of the issues you are saying with my Woodland mill. Maybe they've made improvements? Bought mine in 2020, it went together easily and it's been fairly trouble free. I'm sure I could have spent more money and had an improved mill, but like I mentioned in my first...

    Sawmill Trailer build

    Agree with above. Get some heavy (4" or larger) box tube and use that. My mill is on the trailer from woodland mills, and it has very little resistance to twisting. Channel/angle won't resist the twist, and you'll spend more time trying to level it. If you don't mind some extra time leveling...

    JD300 Rough Start and Stalls when moving or using hydraulics

    Seems there's a lot going on here. The overheating - I would not run this machine without a temperature gauge. Frankly, I wouldn't run any machine of this complexity and cost without a temp gauge. But that's especially true for one that has known cooling issues. Waiting for signs to show up is...

    JD300 Rough Start and Stalls when moving or using hydraulics

    Hm, no reason to apologize, thank you for correcting me. They do all have closed center hydraulics though, correct? My bigger point was that the system pressure is controlled by the pump, not a relief valve. So running to the end of a function would load an open center system, but would not load...

    JD300 Rough Start and Stalls when moving or using hydraulics

    Revving high doesn't take much fuel. Operating under power does. Operating under power while revving is what takes the most fuel. But high rpms with no load won't be enough to show you a fuel restriction. I'm not totally sure the fuel configuration on that machine, but in general you can test...

    What's the purpose of a bypass on a cylinder?

    Read my first reply. I don't think what you are looking at is a bypass line. Typically a relief valve is included within the control valve. Not the cylinder. For clarity, I'm assuming you are talking about a line like this one pictured?

    What's the purpose of a bypass on a cylinder?

    You are probably seeing the line to pressurize the upper part of the cylinder. Lots of cylinders run that in hard line attached to the cylinder itself. Makes it so the flex hoses only need to be routed to the base of the cylinder.

    640 loader issue

    If I were testing this, I would connect the gauge directly to the quick coupler, and not let the fluid flow further to the pistons. If you get expected pressure, you can test again in a tee configuration. If you get low pressure only then, it would be internal leakage. From the tests you ran...

    JD300 Rough Start and Stalls when moving or using hydraulics

    JD 300 uses a closed center hydraulic system, so there aren't any relief valves. If bogging when using hydraulics that's an engine power issue. You also said it's bogging when driving it, and the drive system is not powered by hydraulics, so again points to an engine power issue. You are on...

    What to look for when buying a used excavator?

    If you have any interest in driving to Southeastern Connecticut, I can show you mine. The good, the bad, and the ugly. Or if you have a buddy that has one, I think looking over one in person will be far more valuable to you than trying to describe online. I bought a 1992 Hitachi 120, with...

    Would you book a trip to outer space or under sea?

    Lots of people get killed using tractors. Or riding motorcycles. Or cutting trees. Or hiking. Or driving a car. The world can be a dangerous place. Be thankful you've made it this far while continuing whatever dangerous activities you partake in. I think a deep sea expedition wouldn't be the...

    3600 Series

    I noticed on Mahindras website that the 3600 series no longer appears on the main page. In general, the models look stripped down compared to prior offerings, there is no Mpower series, 7000 series, etc. When you do a manual google search though, you can still find the 3600 and 7000 series...

    husqvarna 395xp

    I have not noticed that it works drastically different than my other saws. Maybe a bit stiffer. Did you trip the brake off the saw or on it?
