Gripping well too, considering it’s tracks.Matching up well

Totally agree. The 200hp is on 650s but the 180 is on 18.4r46. The dtm is much better on the 7720 tho , it has max rev limits that work so can lug down , while the 7485 just opened up and spun away , so dtm never used for ploughing ime.The key difference (other than hp) since those halcyon days is tyre width.
I used to plough with a Ford 5600 on 13.6r38, with wheel weights, pulling 4x12" furrows.
That became a 4x12" reversible on a 2wd MF399 on 16.9r38, but struggled in heavy going....so we put the 4wd 956XL turbo Nash on the plough....and broke the plough
That became 4x14" on an 8340 Ford, on 20.8r38, which again struggled for grip, the Maxxum with a heavier back end, and wheel weights (it was a loader tractor) on 16.9r38 pulled it much easier
5x14" (with press) fared fairly well on a 6290MF on 18.4r38, then a 6480 on 20.8r38 (but both needed weights and diff lock in tough going
6x14" on a MF 7495 on 20.8r42 went well, that thing did put the power down very well indeed (shouldn't of sold that tractor!)
We now have a 7f semi mounted vari width plough, usually hung on a 7620 MF on 20.8r42/16.9r30 wheels. Its amazing how well it goes really, a ton on the front and away she goes.
The key is grip, not power. An engine pulls best when its governing (that's the definition of 'Grunt') - the engine needs to pull down before grip is lost, then traction is maximised. Highest gear lowest rev kind of thinking.
I see people on 650&710 tyres revving and chewing and spinning pulling smallish ploughs with biggish horsepower. Put narrower wheels on and she'll go much better.
We until recently had two 7620's - virtually identical tractors, except the wheels. The one on the 20.8r42's would always outgrip the other on 620's, almost regardless of job. A narrow, but long footprint is far more effective than a short wide one. Think how a crawler works.
I was ploughing after beet with 7f on our old 7490 (on 580's) It's a proper old lugger is that tractor, just set the supervisor dial to about 15%, set the A throttle to about 2100, cruise to about 7kph, diff lock in and she'll sit down and pull at 1750rpm all the way up the field.Totally agree.

Isn’t that telling you something?I'm convinced things are getting harder . Back when I first started I was ploughing with a 3070 Massey on a 4 furrow and dropping the back furr off in the heavy stuff when it got wet but rarely remember having to stop ploughing . More recently building up to circa 150hp on the 4 and this winter currently sitting with a 200hp on a 5furr and a 180hp on a 4 , both of which haven't been able to move this month so far .
Climate change ..?Isn’t that telling you something?
Yep, I have no problem pulling a 5f on my direct drilling.Isn’t that telling you something?
It came up earlier in this thread and is stated on the website; if you copy the design yourself and grow a crop with it, it is illegal to sell that crop or use it for any commercial purpose....
That's what cultivation does to soilI'm convinced things are getting harder .

I’m busy fitting 3 point linkage to my hovercraft so I can get a Triton on demo and get some beans in before the end of Feb . Have been looking on their website to see how much thrust a 6m requires .Ohhh I’m really missing this thread Not a day goes by that I don’t wake up hoping to be greeted by lots of posts on TFF of Triton drilled crops not being under water; being accompanied by a close-up of one plant growing happily away thus proving the point, by stories of frontier rejected grain because the grower had drilled it with a demonstrator Triton but not actually bought it; by posts that drilling into standing water is not only possible with a Triton but is positively encouraged because the sideways movement of the closing tine retains said-moisture around the seed for these dry springs we are having....
You were allowed into the website?! I always thought you had a funny handshake....!I’m busy fitting 3 point linkage to my hovercraft so I can get a Triton on demo and get some beans in before the end of Feb . Have been looking on their website to see how much thrust a 6m requires .
Haha pity this isn’t Twitter .... you’d be another Triton blockage !Ohhh I’m really missing this thread ☹ Not a day goes by that I don’t wake up hoping to be greeted by lots of posts on TFF of Triton drilled crops not being under water; being accompanied by a close-up of one plant growing happily away thus proving the point, by stories of frontier rejected grain because the grower had drilled it with a demonstrator Triton but not actually bought it; by posts that drilling into standing water is not only possible with a Triton but is positively encouraged because the sideways movement of the closing tine retains said-moisture around the seed for these dry springs we are having....
Just had a look at their Twitter. Jolly interesting.
Is it me or does the pinned video of it behind the jd crawler show it waggling up and down all over the place? Hardly the drill's fault, but surely claiming perfect seed placement is a bit rich?
As is a 400hp crawler on 3m, when their recommended horsepower for the same drill is a 130hp JD6900!
