New to New Holland (TD 5.95) - PTO Warning light problem

[GerMarsh]

Hello all,

Firstly, I wonder if the TD5 is not a global model as I do not see many of them. I also notice other NH models which don't exist in the UK. (I am in West Wales.)

Secondly, I part-exchanged an old Massey 362 for the tractor as the old girl was stuck in low range and I needed a tractor fairly quickly for getting bales in...

As soon as I picked up a "small square" bale, I noticed that the tractor got a bit light at the back - especially on the slope - so I came up with the strange looking counter-weight!

It had some starting problems from when I bought it but I put that down to it being a more modern tractor (2016 compared with 1995) and me not knowing what the hell I am doing most of the time. However, one morning it refused to start even though I followed the manual for sticking things in neutral etc. Mechanic arrived and ended up bypassing a switch for the shuttle as the computer thought the shuttle was not in neutral.

From yesterday I have had a really strange problem when trying out a topper for the first time. (I won't go into detail about shear bolts shearing!)

This model has three PTO controls - from rear to front:

1. 540 or 100 rpm selector;
2. Engine or road wheel drive;
3. What the manual refers to as the Clutch Control Lever which engages or disengages the PTO.

Everything worked perfectly when driving a tedder end of last summer but I am now having a problem when I disengage the PTO and switch off the engine, the tractor does not start again. I worked out that it was because the PTO warning light is still illuminated.

After some messing about with the PTO controls the light went off so the tractor did start. What I discovered is that moving the clutch control lever half way backwards and then forwards results in the warning light illuminating briefly. However, when I move the lever to its engaged position (even if the operation selection lever is at neutral) then the warning light will stay on after moving it to the disengaged position. Quickly moving the lever backwards and forwards does not extinguish the light so the tractor thinks the damn thing is still running. I subsequently found out that moving the tractor a few yards will get the lamp to go off. I suspect some cable or switch is getting stuck and the movement is releasing it but I cannot see where.

If anyone could point me to a likely cause I would be very grateful!

Thank you,

Gerald.

First off, welcome to TBN. When I first got my 2019 NH Workmaster 75 and turned off the PTO, the PTO light would stay on. Same issue as your's, it would not restart. After I shut it off and let it cool off, I could move the PTO lever back and forth to get the light off for it to restart. NH adjusted the PTO clutch pressure to fix it. After a few years it started again. I added an overrunning clutch on the PTO shaft and that fixed the problem.

Thank you very much for your prompt reply WM75Guy. I had a funny feeling that it would not be a simple switch like the shuttle problem.

I think when I move the PTO lever to off the overrunning clutch takes the pressure from the spinning implement off the PTO shaft which allows the internal PTO clutch to move to off.

I have a case 75C, similar tractor. I am very deliberate with turning on/off the pto. Or it will stick. I always engage the pto at 1200-1500 RPMs. To disengage, I always back down the RPMs a little, then disengage, then immediately drop to idle. This will help the teeth to disengage with the rotational inertia of the equipment

Thank you all for your help - This is a different beast than the old MF 362 and much more different than my old Yanmar! This problem happens even if there is no equipment attached to the PTO.

Nice picture of the tractor on your farm. Is it a TD5.95 or a T5.95?

Yup mine does it also with nothing attached.

TD5.95. I don't think I have encountered a T5 around here. There are a few T6's and big T7's.

It is a TD5.95. That is the Taf estuary in Carmarthenshire, west Wales. We have a lot of rain!
