The John Deere 4230 is a 2WD or 4WD (optional) row-crop tractor from the Generation II series. This tractor was manufactured by John Deere in Waterloo, Iowa, USA from 1973 to 1977.
The JD 4230 is equipped with a 6.6 L six-cylinder diesel engine and one of three transmissions: Quad-Range transmission with 16 forward and 6 reverse gears, Powershift transmission with 8 forward and 4 reverse gears or Syncro-Range transmission with 8 forward and 2 reverse gears. During the 1973 model year, the JD 4230 was available with a 5.9 L six-cylinder gasoline engine.
The John Deere 4230 row-crop tractor used the John Deere engine. It is a 6.6 L, 6,620 cm2, (404.0 cu·in) six-cylinder natural aspirated diesel engine with 108.0 mm (4.25 in) of the cylinder bore and 121.0 mm (4.76 in) of the piston stroke. This engine produced 101.5 PS (74.6 kW; 100.0 HP) of maximum output power.
The JD 4230 is equipped with power steering, differential hydraulic wet disc brakes, open operator station (four-post ROPS or Cab was available as an optional) and 140.0 liters (37 US gal.; 30.8 Imp. gal) fuel tank.
Following attachments are available for the John Deere 4230 row-crop tractor:

Having trouble with a foreign supply house called hydraulic
Masters. I bought a joystick control manifold from them in 2021 and it sat for a season due to my also haveing a wife dying from Alzheimers and I just didn’t go out to the farms till the followng year. Wen I did I found out that the valve system I was sent was not nearly large enough and now I realize that the Polack that sent it to me was reading my 21 Gallons of flow per min to be 21 litres per minute so as it would be my luck while trying to explain my situation to the folks on email I was told to go away and sut up and all kinds of things we here in the unittes states would be in court for. But these guys and gals are not that swift
I found out lately that the manifold is bypassing oil through the spools to the tank and the oil in the transmission gets hot prematurely and stays pretty hot while in operation. have installed a stop on the supply after the power bewyong block and so when the system doesn’t need the loader I closed off the control manfold and it is ok and other than the hissing I listen to while I am using the loader I am ok with the use of the valve. Well I found out this year that the valve was too small and then
I heard the bypassing and when I asked them abiout the issues they keep telling me to take the tractor to a compenant shop! and have it installed properly. I find the redundant ignorance is coming from their technician who admitted finally he didn’t ever work on actual tractors but setup displays for their exhibts. I am thinking going to E-bay and then to a legal firm that I use to get satisfactio0n and replacing the valve with a more standard part ans just tying it to the 4 function lines and loader that I have on the tractor. Can someone,for my edification, tell me if there is a load sense line or port on the high pressure pump that feeds the remotes? Like I mentioned I have a powerbeyond setup on the right hand remote and I put a steel ball valave in line with the supply to the control manifold. and when I open the valve with the tractore running you can hear a swishing and hissing at the control valve assembly until you use the loadre or otherwise load the supply line. The Polacks suggestion is to have a competant mechanhic look at the installation and attach the LS or the load sense line to the port on the pump.Wherre might tht be and what limiting action does that have if there is one ….. You see I ask a loaded queston as I know that the spring valves in the cavetqation plate are the by pass ing circuit for the pressure control on the front pump but the polacks don’t know that you can’t tie their LS circuit to this as it would artificially limit the pressure on the pump and the closed system would loose its 22-2300 lbs control. I don’t know what the effect would be as I would never do such a thing but I wish to gt these buttheads to take the first pump thay sold me back and now that I am aware that I am dealing with horse trading know nothing people that would defile their grand mother to sell their products, I am going back to US suppliers that I can talk to and trust with my money.
