FR TSR 102 plough trip

[AdrianNPMajor]

Just refurbishing the trip mechanism on my TSR 102 plough.
The outer spring on the rod that operates the trip mechanism went ping after the roll pin failed. I noticed that the rod had bent. Looking at my friend's plough, the rod is also bent, though the outer spring is still in place. Just wondering if this is a design weakness. I hesitate to draw this conclusion as I'm no expert. I hesitate also as the plough is a design classic.
Best, Adrian.

Think we are in the same boat Adrian, I have just bought a 102 and it does not latch in to turn over. Mine has a missing outer spring and no roll pin but does have the obligatory bent rod and a bent turnover link. Apart from that it has new SCN bodies and points but no discs which is not a problem to me.

Will know more when I start to repair it but at the moment the soldering iron calls!

Hello Brian
Everything about the plough, including the trip mechanism, is chunky, with the exception of the rod in question.
I'm having a new one made of a larger diameter but still small enough in diameter to accept the original springs (I was hoping to source some thick-walled tube rather than rod, but couldn't find any). The small pivot bracket that the rod passes through, the hole in the middle of which had become elongated, is being drilled out to take the new rod.
I'll let you know how I get on.
In the event of a successful outcome (nothing like tempting fate! ) I'll post a photo of the plough attached to the Major.
Below is a photo of Frank's TSR 102.
Best, Adrian.

Just a quick ps, Brian.
The turnover link got bent by the operator having to jump off the tractor to rotate the plough (which you have to do if the trip mechanism has failed in the way that it has with your plough and mine). When you pull the trip lever and pull on the plough to spin it, it's easy in the heat of the moment to try to rotate the plough in the wrong direction, which stretches and bends the turnover link.
I know - I've done it!
Best, Adrian.

[AdrianNPMajor]

I replaced the bent turnover link.
Best, Adrian.

I reckon it's bad for that link if you lift the plough while still moving forwards, the 'bang' as the plough pivots forward on the cross-shaft, is the link being put under sudden tension?
Mine taught me the hard way, and has stripped its threads so I welded it, but it isn't strong enough to withstand thoughtless use..

Hello Brian
New rod fitted. Works well.
Didn't have a roll pin in stock, so tested the system with a split pin.
Best, Adrian.

Here's a video of the plough attached to the Major.
Apologies for the shaky camera work towards the end. I had to change hands to be able to push the tractor forwards an inch to get the trip mechanism to latch, which would happen naturally in operation.
Best, Adrian.

I am missing the part the rod goes through, someone had been trying to plough with mine on the back of an IMT (like a Fergy 35) and had removed the back furrows and turned one attaching pin upside down. They had dismantled and lost the turnover linkage and one spring and had thrashed the rear furrow bolts out ruining the threads.

So I am looking for the three bolts that retain the rear furrows, the turnover linkage as you show and any other bits I find missing when I start. I have got a depth wheel and a handbook though.

[blackbob]

Brian so is it a 102 you have? Because I have the carcasse of a 103 3-furrow which I'm using for spares, as well as a complete 102, so I can send you bolts if I have them... I don't have any turnover bits though, the 103 had a hydraulic turnover, and anyway the headstock was stolen along with some other stuff a few years ago when scrap was valuable

[Brian]

Thanks Bob, that would be very handy if you have the bolts. Yes, mine is a 102 and the 103, 104, 105 and 107 are all built up from the same components.

I have an 82 which I am scrapping once the price goes up a bit but it is a different tripping mechanism. I have more experience with the 80 Series as they were the ploughs that we sold and serviced. The 82 is heavier than the 102 with the box section boom. 82's used to break the cast frame where the big pin goes through. Ransomes used to heat the frame and freeze the pin then press the two together so I built up a lot of strength with a 14 lb hammer when we had to fit new frames.

Let me know the cost of the bolts and shipping.

Hello Brian
Lovely project you have taken on.
In your experience, did the TSR102 overlap with the Major at your dealership, or did it come in with the next range of tractors?
Always wondered which frame was heavier - the solid bar or box section. Good to have an answer.
Could I ask you about the depth wheel? Two of my friends prefer to have one on the TSR102 - one ploughs with a Super Major, the other with a modern Case 4x4.
I'd like a depth wheel also, but not having one I do find that the Super Major depth control linkage does a good job without the wheel. My question is, what does the depth wheel add to the equation when ploughing with a Super?
Many thanks.
Best, Adrian.

[Brian]

The TSR range came in way after the Major was out of production so there was no overlap, I was selling them in 1975 so they came out about 1973 or 4.

Depth wheel works well with tractors ploughing on sandy land or with tractors which do not have a good draft control like the Super Major. Nuffy has a slightly weird system in that it has two pumps, one for the main lift and one for draft control. The main lift pressure is set for 2400 psi but the draft control pump is only set at 1400 psi so, although it can lift the plough easily, when using draft control, the lift does not have enough power to control the depth with a heavy plough and heavy land. The depth wheel sorts the problem, stopping the plough "diving" and allows the tractor to use the low pressure pump to add just enough weight transfer.

They also allow the plough to hold a more constant depth and take a fair bit of load from the tractor hydraulic system.

[AdrianNPMajor]

Thanks, Brian.
Which tractor will you use to pull your plough when you've refurbished it?
What kind of soil do you have in your area?
Best, Adrian.

[blackbob]

Thanks Bob, that would be very handy if you have the bolts...
Ransomes used to heat the frame and freeze the pin then press the two together

Is that what they did with the frame bolts too... I had a quick try to get some of these bolts out today, got the nuts off easily but the bolts are very tight in the frame, and you can't get a straight hit with a big hammer.. I'll try a bit of heat, hope you aren't an impatient sort

[Brian]

No worries Bob, the old bolts are in place with no nuts on and they are so tight that they do not move, wouldn't want to use her like that but it got me home.

On about six acres of ploughable land I have, a Ransomes Robin, a single furrow deep digger, a Ford PM, a three furrow Ransomes, a two furrow Ransomes, a TS82 and the TSR102 so I do have a bit of a choice to keep me going.

The 102 will go behind the Nuffield, I still have not done a lot of work on my Super Major, really must get her operational again.

[blackbob]

On about six hundred acres of ploughable land I have, a Ransomes Robin, a single furrow deep digger, a Ford PM, a three furrow Ransomes, a two furrow Ransomes, a TS82 and the TSR102 so I do have a bit of a choice to keep me going.

Er; 6 or 600 acres?

I was being mischievous

Must be quite a spectacle when all the staff are out using those ploughs
