Mitsubishi MT4201FS

[ptsg]

I was checking some images online and found one with the sticker still intact and the little lever by the steering wheel may be used to turn the PTO on and off.

Here is the picture from a MT4501:

So it may have a dry clutch after all by going with the manual that Caustic provided, however I can't see how moving the steering wheel would after the drive with a dry clutch setup.

Something does not quite line up in that behavior, I agree.

Can you take an image of your shifter and pedal area both towards the seat and steering wheel? The other images do not quite show enough.

The only thing I can think of where turning would affect the clutch is if the tractor has power steering and the fluid is low (however that is usually only in one direction), or maybe if the rear difflock is getting activated with the tight clutch?

Actually, your last two images do not match it at all as far as I can tell, that is a much newer chassis style.

guy who sold it to me said it was a 1989 model. thank you.

That makes sense. This tractor's pto is engaged all the time IF the PTO gearbox is in a gear. I will check that out. Thank you! Still more mysteries to solve, but this solves one of my questions. I will check to see if there is an adjustment to make this level functional.

That lever usually mean it's a shuttle shift. The means you flip that lever to forward or backwards. This shuttle can either being mechanical with a dry clutch or hydraulic with two clutch packs, one for each direction. In this later case the clutch pedal just dumps the pressure of the clutch packs.

However, that lever doesn't look quite right to me. Almost if it is disconnected. It looks way to close to the dash both. Should be higher, almost as the same lever of the steering wheel. Have tried to peek under those covers to look for anything obviously wrong?

I will pull the covers off and check it out. That would answer a lot of questions. if this is out of adjustment or not working, could explain my troubles. Thank you.

Pstg 's image does somewhat match your tractor, there is a difference in the shifters on the tunnel though. But the console is definitely the same layout.

I do have power steering and I believe it is common to the transmission hydraulics. I have checked that level next to the PTO and Gear Shifters and the level is in the proper range. I will take a picture of them in the morning and post, thank you. but I can tell you I have a clutch on the left, dual brake pedals that are together on the right. in the middle I have PTO, 4 speeds, and the transmission, with 4 speeds. On the left side of my seat, I have High and Low range levers and forward and reverse.

 

[sixty2chevy2]

also, my engine has four cylinders.

 

[CausticUrbanCoast]

Your layout look like this? This is a D2350.

 

[CausticUrbanCoast]

Aha! MT2801D

 

[sixty2chevy2]

This morning's pictures. And the gearbox does look very much like the one pictured by Caustic. And I see a filler for hydraulic fluid next to the PTO release lever on pic 6 now that I pay attention.

Can you pull the numbers on your engine and confirm whether it is HST or not?

That model number seems to be grey, which means it is a mixed parts tractor. Likely the chassis and engine originally belonged to different tractors.

Mainly what need to be determined is if you have a HST transmission, single, or two stage clutch. It seems your tractor could be around 40-50hp, so all options are in the table.

If it's a single or dual stage clutch and it's not a linkage issue, then it seems like you may need to inspect your clutch fork and plate. However, that would only be considered after attempting to readjust your clutch linkage first. Having zero freeplay seems like someone may have already messed around with it, there should be a small amount.

The only identifiable numbers are a stamped 4800 on the side of the block.

 

[sixty2chevy2]

Here are the numbers on the block. I have also included the hydraulic 'manifold' where the lever on the dash actuates. pic grt shows the rod connecting to the hydraulic manifold and filter assembly.

 

[CausticUrbanCoast]

Closest I can figure on that block number is that it might be the generator engine produced by Mitsubishi Fuso and used in Shibarura tractors (who also made some of the New Holland, ford, case IHI tractors and may have used this engine).

It seems it is not uncommon for Shibaura tractors to be rebrands as Mitsubishi in north America.

If that is the case it is a Mitsubishi-Fuso D3 series engine, most likely the 4D34-T or an earlier version like the 4D33 or 4D32. However Mitsubishi-Fuso also lists it for wheel loaders in the 50-87hp range.

Would need to do a bunch of measuring to confirm or disprove that.

Caustic,

I am happy to gather whatever information you need to help me. I want to better understand this tractor and will need a parts manual and several parts to get her where I want her. Thank you very much.
