    PT 1850 oil and filter-change geezer-reminders

    Hi all, Long time no post -- sorry Covid kinda knocked things loose for a few years and I'm just now getting back to the PT maintenance. Which means I forgot a lot of stuff (and am more likely to forget it again). So here's a link to a little "reminders" post I just wrote myself...

    Weird electrical puzzler - breaker pops, the PT1850 runs better until it's shut off

    Hi all, sorry to be such a fair-weather member of the forum. I only bring you puzzlers and then off I go for a while. Anyway, here's this year's puzzler: reset circuit breaker Turn ignition on without starting motor -- I get the normal beeps, flashing strobe and 12.4 volts on the gauge...

    Draft-control valve replacement fixes all kinds of things

    Hi all, Remember my "1850 hydraulic pressure pulsates" puzzler a while back? Here's the link to the thread: http://www.tractorbynet.com/forums/power-trac/313875-1850-hydraulic-pressure-pulsates-any.html The semi-OK cure was the replacement of the brake-tender and charging valves, but things...

    1850 Hydraulic pressure pulsates - any theories for cause?

    Hi all, I've just laid down a huge time-consuming piece of volunteer work which means I have a lot more time to get in trouble with my 1850. :) So today I decided to do the routine maintenance and replace the hydraulic filter. When I fired up (after bleeding), the hydraulic pressure started...

    Any experience with "lighter" tire foam?

    Hi all, I was at the tire place today and the sales person pitched me tire-foaming, saying that the new stuff is way lighter than the old foam. He's going to get me some more info and call me, but I was curious if anybody has had any experience with it. I really like the idea of foaming the...

    Need to dig a 5x5x6-foot hole - can I do it with the grapple bucket?

    Ok, this is the nuttiest project I've taken on here at the farm -- putting up a 100' radio tower for ham-radio and microwave data antennas. I've got me a bead on a nifty 100' self-supporting tower that needs a pretty darn substantial base -- and I'm thinking about using the PT to dig the hole...

    Hydraulic leak - Newbie question

    I've developed what I hope is a minor leak at the place where the hose meets the cylinder on the gizmo that locks the implement in place. Not a real big deal, since it's only under pressure when you're actually locking or unlocking. But I decided to get in there and see what was going on...

    Winter snow pictures

    Ah! We got a nice 10-incher last weekend, Marcie took some cool pictures and stuck them in her blog about the farm, so I thought I'd take the opportunity to kick off the (sometimes) annual winter snowplowing pictures thread this year. Here's a link to Marcie's blog entry -- scroll down just a...

    1850 (maybe 1845 too) - Replacement oil cooler

    hi gang, i'm following up on a comment made in a post about how bad the 18xx's are for overheating. it turns out that there is indeed an "Ag oil cooler" that can be ordered from Deutz that may be what we're looking for. i'm still researching and hope to have a drawing that i'll post to this...

    Question about disassembling the accumulator

    Hi gang, I'm fixing blown seals in my accumulator today and would normally call Terry about this one -- but it's Saturday and they're not around. I've attached a photo of where I'm at -- I've removed the big spring and the seal fitting. What you're looking at is the piston. Which doesn't...

    Oil & Fuel  Cross-threaded fuel and hydraulic fluid caps

    Anybody else run into this? I've managed to cross-thread *both* the fuel cap and the hydraulic fluid cap on the 1850. These are both basically the same cap, a plastic threaded affair made out of nice soft plastic that's easy to screw on crooked. And once you do that a couple times, you're...

    2 questions; operating temperature and oil leaks

    Hi gang... Wow. A fella disappears for winter in Wisconsin, returns, and finds all kinds of posts to read in the PT forum. I feel like a woodchuck, waking up from winter hibernation. But spring has indeed returned, and with it Mikey breaking stuff. Here's a link to Marcie's blog, showing...

    Tilt seat -- theory of operation

    Got past 10 hours without breakin' nothin' on the 1850 -- busted a stem off a tire at 12 hours. 'Sure is nice to have duallies to get me home to the air wrench. <grin> Here's my newbie question of the week. Every once in a while the tilt seat "loses it's mind." It's almost as though it's...

    Thinning on steep slopes with the PT 1850

    Hi Power-Trac People. I've been over in the General Owning/Operating forum asking about this, but I'm homing in on the PT 1850 and want to ask you PT experts the same thing. Here's a link to the thread. And here's the short version. Marcie and I have some really steep (like 30-45 degrees...

    Clearing steep, wooded hillsides, PT 1850 or what?

    Hi gang -- long-time lurker Mike here. But I've got a puzzler that I bet some of you can help out with. Marcie and I have a farm in western Wisconsin that we are restoring back to native habitat. You know, prairies, wetlands, savanna. The puzzler can be seen in these pictures of a remant...

    Mowing  Gyro action -- an aid to hillside mowing?

    Hi gang, This is my first post (usual story, 'been lurking for a long time, very helpful discussions, etc.). I looked for this before I posted, so apologies if I missed it. But here's a brain teaser. I am wondering how much stability on a hill the gyroscopic action of a rotory (or flail)...
