Draft control and ploughing.

[rob h]

slotted top link is usless on our fields with soil in small patches of sand mixed in our heavy clay. modern tractors with electronic control set on draught keeps a good even depth using the fixed pin hole.

Fixed hole is for top link sensing not bottom

Maybe but it works better than the slotted hole on our tractors

Last time I saw a fixed hole used properly was on a wee short 3f kv plough on my fathers Ford 6810 in 1997 .
Even then it needed the pin to be loose so that any changes in direction of force caused the draft system to work.
Bottom link sensing needs the top link pin to be loose (slotted hole) to let the bottom link sensing work properly.

Long ploughs you need the slotted hole to help get them in and out evenly at the ends as well. Also over hill tops or through low dips putting my long clearance in the fixed hole would be a disaster .

JD 6155M
5 furrow KV plough
top bar tractor end - middle hole
plough end - slotted hole
draft - middle setting
if you have draft setting too high here the plough would be out of the ground most of the time.

Well I never

 

[Farma Parma]

Same here,never use draft

so you just bury the arms too the bottom do you? i cant wait too see this ploughing
Impossible not to go with some draft on & ive ploughed long enough to know
Regardless of in furrow or out of furrow
Ploughs serge in n out of soil as your driving over poss wheelings etc etc
The Tractors linkage via DRAFT control sences all of this & keeps it at the same depth.
I could literally make 240hp standstill all four wheels spinning if you lower linkage right down & have draft on position setting.
So enlighten us one how its done???

There is one every week iam sure.

I don't drop plough down as you suggest ,have set in position and hold at depth I want on 6 f kv ,top link in floating hole,not going to get into a slanging match ,I have done my share of ploughing ,unfortunately,,as quoted above if in draft the plough won't hold constant depth,sinks in in soft and rides out in hard

Maybes its sand your in ive no idea but ive worked on with many a plough in last 36yr
in all land types.
Sliding top hole as standard on a KV & all tractors bottom link sencing heck even going back to a 2wd Deutz if you forgot to pull the draft lever up it just made an pigs howk & skidded to a stop
All electric linkage since then MF tractors & all had to have some draft on otherwise they all do the same thats all iam saying.
3,4 & 5fr ploughs by the way. Its a first too me thats all.
Ploughing & Draft is linked like Fish n Chips.

That was a brilliant thing when it worked.i pulled a 4 furrow dowdeswell reversible with a 7600 Ford,2wd and it worked brilliantly,thEn had a 4wd 7710 ford that was absolutely useless with the same system.never got it to work right either.
nick...

need plenty of weight on the tractor to be effective. we had it on a ford 7600 2wd with rear wheel weights, some water in the tyres and 16 wafer weights on the front. the plough was a ransomes tsr 108 3f reversible. land varied from medium loam to stuff that was so heavy/tight that it could bring the tractor to its knees in low 3rd.

So what will keep a plough at a constant depth?
A) Draft control off, height of lift arms set on depth stop.
B) Draft control on, height of lift arms changing with draft.

Simple question.

What tractor are you pulling 6 furrows with there? This is a subject of conversation on another thread.

I use the slot on the headstock and wheel on the back. Top link pin generally at the front third of the slot in work. This is obviously with lower link electronic sensing. Sensitivity is set so the the lift and lower lights blink alternately, not too fast, during normal work. Drop speed to automatic.

I’ve often wondered what the point of the slot is-surely every time your tractor drops in a hole or goes over over a little bump then the front of the plough does the same thing? For what little ploughing i do I use the fixed hole at the top and the land wheel; extending or retracting the top link to get it level

I do recall however using a dp2 when I was younger that had a floating top link bracket; but that was only because it was so long and if you dropped off the road into a field it needed somewhere to go else it would lift your back wheels off the ground but they would go on big crawlers that would always run level

B as draft should compensate any dips or rises the tractor goes over.

You use the slot and set the draft so the lift arms move just enough to keep the plough at a constant depth this allows for holes and bumps

 

[michael N123]

I can tell straight away when it’s turned off on my land but I’ve no even flat fields I’m constantly going up and down hills with random wet bits

 

[Foxcover]

What about if you’re on flat land?
If draft is turned off and the link arms are set to stop at a set height then the plough will stay level and the front furrow depth will not change, unless you cross a rutted tramline at 90 degrees.
If you turn draft on then the tractor will start varying the depth of the front furrow depending on draft loads, obviously severity of this will depend on settings.
Switch draft off and plough will stay where you put it.

Why are most people thinking that draft control will pull the implement out of the ground. It's designed to keep the implement in the ground at a constant depth.
Case MX then inherited by CNH is the best system I have used. Completely separate draft and position control. Turn position totally off unless you wish to use it as a 'bottom' stop in soft ground. Set the front furrow depth using the draft controller, slotted top link hole with lower link sensing. On a CNH tractor if you have not got DR displayed where the linkage position number normally is, then you aren't set properly. So much better than any draft/position mixer setting.
When you add in a wheel slip limit via the radar, then you can make a plough dance to any tune you wish.
