    830 Hydraulic problems

    I have a 1974 3 cylinder 830 that I picked up for a brush-hog tractor. I knew it would need some work, but it was not in bad shape for it's age. Hydraulic pump started giving some problems, there was about a 10 second lag from the time you lifted the control lever until the arms started...

    JD 830 hydraulic pump replacement - stuck drive yoke

    Changing out the hydraulic pump on my 3 cylinder JD 830 utility tractor. How do you get coupler off the end of the shaft? It is a 3/4" nut, but there's not enough room to get a wrench on the nut. I took an old 11/16" wrench I had and ground away most of the outside and opened the jaws so I...

    Orphan part

    Somebody placed this part in the fork of a tree many years ago and the tree grew around it. I'd noticed it about 15 years ago, the tree finally rotted enough for me to pry it out today. Looks like some kind of adjusting arm, I would guess for a planter or cultivator. Supposedly they grew...

    rural road marker

    This marker recently appeared near the ranch in rural Texas, nailed to my neighbor's fence. This one is where a dirt road meets the county road. I've seen a couple of them at various places, any idea what the purpose might be? Size is about the size of a dessert plate, too small for traffic...

    Computers vs. repairs

    We've all heard about the issues with JD and right to repair, and the problems with computers in general causing downtime on new tractors. What about construction equipment? We have an older JD skid-steer and have had no problems, but we may be in the market for a mini-excavator, and I got to...

    Small scale soybeans

    Attended a wedding just north of Nashville, kind of out in the country between Greenbriar and White House. Not much ag in the area, but quite a few small plots of soybeans that look to be about ready for harvest. Most fields that I saw were less than 5 acres. So what do you do with small plots...

    what weight bracket is this?

    Picked up for my little 830 mowing tractor, wonder what models it was originally for? JD or aftermarket? It fits perfectly and will make a great bumper.

    Unknown part on 2018 bat wing mower

    Picked up a model 2018 20' shredder. The mounts for the wing lift cylinders have a part bolted on that doesn't appear to serve any purpose. The part is sort of an L shape, really more like a question mark. I can find no mention of it in the operator's manual. JD parts calls it a strap, part...

    Diagnosing hydraulic problems - long post

    I recently picked up a JD 830 (3 cylinder) as I needed a small utility tractor with a horizontal muffler for bush-hogging near trees, mowing near the stock tanks, etc. It is a 74 model, hours unknown, good tinwork and rear tires, fair maintenance. I bought it from the son of the original...

    new load shaft seals are leaking

    New to me JD 830 (3 cylinder), load shaft seals were leaking and the whole load shaft was in pretty sorry shape, noticeable wear where the seals would ride, threads stripped, etc. So I wanted to fix it right, got all new parts from JD, load shaft, bushings, seals, etc. Cleaned out hydraulic...

    Finish mower ID

    Came with a recent tractor purchase. No ID tags I can find, but built pretty heavy. Any idea who made it?

    School me on load shaft seals

    I've seen lots of posts on here about the problems with them on 4020's and others, and since I have a 4020, I figured I would have to do that fix sometime. As it turns out, I picked up a 3 cylinder 830 that needs new load shaft seals, so I guess the time has come to tackle that job. I've...

    Power steering rebuild in 830 (3 cylinder)

    Power steering is leaking fluid, believe it is all from the top right under the steering wheel, but not sure that is the only source. How hard is the rebuild? Is it just replacing seals, or can it be more involved? Any special tools? Are all usually needed parts available? Assume the...

    303 oil replacement

    OK, I know that 303 hydraulic oil had legal problems, and I guess it is not available anymore. 303 was the spec oil for my JD 4020, and I need to pick up another 5 gallons to have on hand. I stopped by the local tractor supply place figuring that the new hydraulic oil would say whether it was...

    15' versus 20' mower

    Old batwing mower is on it's last lap, frame is cracked in several places and I'm shopping around for a replacement. My pastures are pretty flat, but do have some low places where water drains, some terraces to control water flow. My old mower was 13 1/2', so looking at used 15' mowers. I...

    touchless front end alignment check

    OK, not strictly tractor related, but tractor front ends need alignment too. Daughter took her Toyota in for service, they have a new Hunter alignment checking system. They drive the car over a device that measures alignment with lasers and immediately gives a report whether your car needs...

    hay processors

    I've seen the videos of people feeding cattle in the winter with hay processors that can carry up to 6 bales, it looks like a great time saver. But curious about what happens with the twine or net wrap on the hay, I assume the grinder just chews it up. Even if you tried to remove it, it's hard...

    4020 air filter problems followup

    Last week, I posted looking for the Donaldson part number for the rubber baffle plate in a 4020 diesel dry air filter. I finally found that a Donaldson P105050 should sub for a JD R39828. But by the time I pay shipping and sales tax, it is about the same price as the JD part.

    4020 air filter problems

    '67 diesel 4020 powershift with dry type air filter. I believe it is a Donaldson. The rubber cup that fits into the metal bottom has crumbled due to age, and I need a replacement. My parts manual says it is a R 39828 dust cup baffle. JD online shows that part number to be an isolator and it...

    whatizit?

    Bought some equipment from a local power plant that was shut down, and a bunch of these were in a box. Some kind of latch, but any idea how or where it was used?
