PTO shaft TX1240

[Marcle]

Okay, this may seem a stupid question to ask, so let me explain first. Its a new machine to me, its currently fitted with a back actor (rear end digger) with a hydraulic pump fitted to the rear PTO shaft so I can't see the actual PTO shaft as the pump drive coupling is push home. Also its tipping down here and no where under cover to work on the machine.

What I'd like to know please, is the front PTO shaft the same size as the rear PTO? Also what would the size be known as please?

Thanks in advance.

The front PTO shaft should be the same, and it runs a bit different. It actually runs off of your fan, or serpentine belt. I have seen people use the front PTO for a hydraulic pump, like you have, however you cannot control it like on the rear. It will just run constantly while the engine is running. If that is allright, then it may be beneficial for you to use it. If you remove the small plate with two screws below your radiator screen, you will reveal the pto shaft. You will need an extension if you go this route. I hope this helps a bit. Do you have a photo of your tractor? The PTO size is 1 3/8.

Hi Mitch,

Thanks for the info, much appreciated.

I will get some photos sorted, but the weather here is awful at present.

I see in another thread you were trying to sort out the hydraulics to fit a front end loader. Mine has the FEL, so can take photos of that as well if you wish.

Whilst on the subject of hydraulics, I have a post in the general hydraulics section (by mistake, thing at the time is was for Iseki) asking about pressure relief valves as my FEL is a bit weak. A member has posted some general help, but its not specific to my machine, so I was wondering as you've said you have a workshop manual, whether you could forward any info on that section please?

Thanks

I can't really help you, I don't think, but we need to see more pictures of your tractor. I'm really interested in the self-leveling bucket and the dual wheel adapters.

On my Yanmar and Kubota machines, the front PTO shaft is of a different diameter. One has a 13 spline female coupling, one has an adapter bolted to the crankshaft pulley, and I've never disassembled the other, but it uses a female fitted splined connection on the crankshaft pulley as well. If you are trying to run another hydraulic pump, you should be able to match Lovejoy style couplings to the pump and to the crankshaft pulley. If there isn't a fitting on the pulley, I have made my own to attach. Any machine shop can do this for you if you don't want to do it yourself.

If you are trying to run a three point type implement, you will probably really struggle. The front PTO turns at engine speed, something like 5 times faster than the rear PTO.

Thank you so much for posting the photos! That is a great looking tractor! I really like the dual wheels on the rear. I knew that they could be set up this way, however I have never seen a TX with the dual rears installed. The fel set up is good to see as well. Thanks for the photos, including the hydraulic photo from under the seat! I did quite a bit of reading in the service manual, and I was not able to find anything specific to the loader, however there were several pages coving the hydraulics. It did suggest that there is a hydraulic bleed screw under the seat, as noted in the diagram below. That may be the issue. You may want to bleed your hydraulic system, it is possible that you have air in the system causing it to run slowly. I also added a few pages from the service manual on regular service that may be helpful as well. I hope this helps a bit. The service manual only covered the tractor, and the rotovator. Thanks again for the photos!

This is a photo of the front PTO. I was able to get my weights off, and the front cover off when I flushed my radiator. As you can see, you will need an extension to use it:

Marcle,
I have that same exact tractor minus the rear dualies.
Same color,
and same Polymarks Beaver Backhoe(rear end differ) and FEL.

Hi Mitch,
Thanks for the excellent photos. There's no cover over mine (by design) though as you say it will need an extension to be usable, plus part of the front end loader bracketery fouls access to it.

I see it has a toothed drive belt, is it a Vee belt or a timing belt?

Hi Dave,

I have come across your videos on Youtube. Trying to pick up large objects is always difficult! I'm going to add a 'thumb' on to mine as it makes it so much easier when moving large stones etc.

As for my rear wheels, I'm not sure about them. The previous owner fitted them as he was frightened of rolling it, though he never added a roll protection bar, strange... They will certainly be a hindrance when using things like Rotavators as you'll be constantly driving over your fresh work.

Hi, hope your doing well, the belt runs the alternator, the water pump, and the crankshaft, so I guess it would be a timing belt? The crankshaft portion, it the wheel that has the pro attachment on it it. It is designed for running a front PTO, so it will not harm the engine if you use it, it how they powered the mowers that were sometimes sold with the tractors. As far as the rear dual wheels, I would imagine that you could take one set off, and then you would have a spare set when you need it. I looked in my manual, and if he used Iseki parts to attach the second wheel on each side, then it is pretty easy to remove one set. You could also put turf tires on one set if you wanted to have a set to drive on your lawn with. My Ag tires tear up my lawn, and leave terrible divits when it is wet, and then my wife gets angry, So I have to be careful where I drive. You could probably find a Roll Over Protection set up in the UK fairly easy, since there are a lot of Iseki TX's around. Well, a lot more than we have in the US. The ROPS that I bought were manufactured in Australia, and they sell them in the UK, in Bedfordshire, through Minitrac, or Yenibiz, in Belgium. Hercules ROPS - Europe

I used to make a lot of competition roll cages for 4x4 off roaders and still have the benders etc. so making one for the Iseki is not an issue, plus my land is fairly flat.

With regards to the dual wheels, the previous owner made his own adaptors using three bits of hex bar threaded either end, then on the sides flat steel welded between them to stop them bending over when under stress. There's already three holes in the wheels to locate the adaptor on which makes the job easy. As for lawn tyres, I have several sets of wheels and tyres from my competition off road days that are not as aggressive as the chevron tyres, so may fit those.

Bit of a quick update on the front PTO. In an earlier post it was suggested that the front PTO diameter is the same size as the rear, which may be 1-3/8. So far I've not had access to the rear PTO shaft due to the back hoe. However last weekend I modified the front framework to give me clear access to the front PTO shaft, this work has now clearly established the outside diameter to be 1" (25.4mm).

So far I've not found any adaptors for such a small pto shaft, so may have to remove the existing shaft and machine another to fit.

 

[NHmitch]

Hi,

I do know of an adapter that I think will work. I think that this one should fit perfectly. It is located in the UK. Ferguson Tractor T20 PTO Adapter Sleeve | eBay good to know, I always thought the front PTO was the same size. They sell these adapters here as well, and I may have to try one. Take care!

 

[Marcle]

Hi Mitch,

The MF sleeve is too big as its for an inch and one eight (1-1/8") where as our shaft is one inch (1"). The shaft is quite simple as shown below

So using an adaptor pto shaft with a more common sized spline I'll machine up a complete new shaft, or at least that's the plan today, just have to see what else I find to convert the size easily.
