    Aftermarket 3-point hitch for 730D

    Hello, I have a 730D tractor that I'd like to add a 3-point hitch to and wanted to see what others have done to make this work. Did some of you buy an aftermarket kit? This tractor didn't come from the factory with 3-point as it doesn't have the bracket where the top link would attach. Would I...

    JD 50 Carb Issue

    I m having an issue getting fuel to the carb bowl on a 50 tractor and can t get it started. I recently put new gaskets in the automatic sediment bowl and it seems to be working correctly as there is fuel shooting out of the line when the engine turns over. After opening the drain on the carb...

    JD 820 Issue

    On my 820 2-cylinder tractor, I ve recently noticed that the tractor will move back and forth a couple inches on its own. This is with the engine running and shifter in neutral. The tractor moves by itself regardless if the clutch is engaged or not. I ve never seen or heard of this problem...

    JD 4640 SCV Issue

    When I try to hook up implement hoses to my 4640, it will only let me lock in one hose. I cannot move the other lever all the way forward to lock it in and complete the circuit. I can push both hoses all the way in, but it will only let me lock in one of them. I ve moved the hydraulic levers...

    IH Field Cultivator Price

    What would an IH 4800 cultivator in good shape be worth at auction? The one I’m looking at is a 24’ with 5 bar spike harrow.

    JD 720/730 3 point lift capacity

    Does anyone know the lift capacity for a 720/730? I have a head mover to put on the 3 point and was curious if it would lift a JD 213 platform? How much does the platform weigh?

    JD 7200 Planter - Bean Meter Options

    I’m looking for a set of bean meters to replace the bean cups on my 7200 planter. Finding a used set of the JD radial meters has proven difficult but new Kinze and Shoup brush meters seem to be priced reasonably. Does anyone know if these brush meters fit on the 7200 planter without any...

    Gasboy Model 60/61 Pump

    I recently bought a fuel tank that has a Gasboy 60/61 pump but I can’t seem to get it working. I hooked it up to a 12V battery and confirmed that there’s 12V at the motor but it doesn’t run. I didn’t see a switch anywhere so I’m guessing it should start as soon as you hook up to the battery. Is...

    JD 820 Thermostat Issue

    On my 820 2-cylinder, I’ve been trying to warm up the engine but the temp gage needle doesn’t move. The upper water pipes get warm but the bottom ones stay cold - does this sound like one or both of the thermostats aren’t opening? The block is getting pretty warm where the temp gage probe screws...

    JD 820 Hydraulic Pump Issues

    The powertrol pump on my 820 (2 cylinder) makes a loud grinding noise when switched to on and the hydraulics don’t work. If I turn the lever a little one way or the other, the grinding goes away. Perhaps it’s not kicking in and for some reason, the lever can be turned all the way around in...

    JD 720D/730D at work

    I've been using a 720 and 730 to farm 80 acres and thought I'd post some pictures of what I did last fall and this spring so far. First, here's the 730 pulling a JD 66 4-bottom plow last fall. I could only pull it in 2nd gear so the field took a LONG time to plow. Next, here's a few...

    John Deere 70 hydraulic pump leak

    On my 70 gas, the hydraulic pump started leaking from a pin that sticks out which is close to the flywheel cover. This pin appears to have a snap ring groove at the end but nothing is in it. The pin can be rotated by hand and it feels a little loose. I've seen it rotate back and forth when the...

    JD 720D Power Steering Dipstick

    On my 720D, I noticed the power steering dipstick has a hole straight thru it. Is there supposed to be a filter or plug in the hole to keep the dirt out? I see that my 730D doesn't have this hole in the dipstick. Does anyone know why they're different? Also, is the fluid level supposed to be...

    JD 720D Value

    I just bought a 720 diesel (S/N 7220972) at an auction in Annawan, IL and was just curious if anyone knows who owned the tractor or what the history of it is? I paid $5500 for the tractor and wanted to get your thoughts if I paid a fair price for it? It seems to be a good running and driving...

    1968 4020 Value

    I'm looking at a 1968 4020 that's up for auction in a couple days and I'm wondering what a fair purchase price would be. It's a power shift and seems to run and drive good. I only drove it when it was cold so not sure if something could act up after its up to operating temp or pulling it hard...

    730D Tractor and 8RW 7200 Planter

    In the spring, I'm looking to plant corn with an 8 row wide 7200 planter and was curious how a 730D would pull it? I have duals for the tractor and plenty of rear wheel weights and am hoping to pull it in 3rd gear. The ground will be worked and is pretty flat. Does anyone know if the tractor...

    JD 730D Black Oil in Exhaust

    On my 730 diesel, I had a problem with the injection pump leaking fuel into the crankcase so I had it rebuilt. Since reinstalling it, I've had an issue with the tractor blowing oil out of the exhaust. It doesn't appear to be engine oil because I just changed oil and it's very clean. The oil...
