If you want to stay with a Deere plow the F115-F125 would be a good match as a fully mounted plow and a semi-mounted would be a F135 or F145.The F115 and F135 have shear bolts for a trip and the other two have a safty trip.To use a semi mounted plow on a two cyclinder you will need to use a quick hitch because the 620 gets it's load and depth control thru the top link and not the bottom three point arms like a 3020 or other new generation row crop tractors.Oliver made some good plows as well.

I often wondered about the use of a "quick hitch" to handle the top link load and depth control properly. I normally use a bottom link sensing tractor with my F145, However, I have been looking at using my restored 720 diesel for family plowing days, an annual tradition for us. My operators manual shows an arrangement for the JD 2020 tractors..I presume with top link sensing... Have you tried it? Thanks

Dad had a 4bottom oliver on his 720 and it would not work right untill he went to a quick hitch.He had to be on the depth contol all the time.Deere mabe a hitch for the semi-mount plows to use the top link for the 2010 tractors.

That is what I was refering to. And the quick hitch will not do what that does. It would just only hold up a top link but not do any good. For bottom link sencing there are one location of pins for the arms but when you go to top link sencing they are loacted lower than the bottom link setting and the mast for the top link works on a piviot that is over the pins for the bottom ling sencing and the piviot ov the mast is what controls the depth for top link use, at least that is the way it was on the M-F 4-14" semi-mounted plow but that tractor and plow are long gone as I am no longer farming as the farm is gone. There was an easy way to set the cross bar on that plow to match the correct wheel tread setting but here in northwest Ohio it was actually too much plow for the 63HP Ford, No way would it have pulled a 16" like other poster said he pulls with a less HP tractor and 50 mile away.

For a 620/630 or 720/730, you HAVE complete control of DEPTH at ALL times, without the upper link...and YES, a 720 will Stroll with 4x16"...

Those are not puney little Shetland Poneys in a 720 D..

You have NO need to worry about a "Top Link", with the JD Semi-Mount plows...as long as the plow is adjusted correctly and the tractor has front weight and good traction.. Ron..

I was looking at a video on Youtube, with a 720 on a F-145 and 4x14" and it sure had all it could handle in 2nd..but he was plowing too deep for a 14" plow and didn't have enough traction, either.. I am beginning to feel a 16" plow doesn't pull very much harder than 14", when plowing 7" deep... Plus, the 16" will not plug nearly as often.. I know..that does not mean I think a JD"B" would pull 2x16"..I KNOW they won't.. but, 3x16" is "Almost" as much plow as 4x14" and they pull a lot easier...

I agree with no need for a top link as I found out the outfit I had worked better if I did not try to use it. Other than that was what I said that a 620-630 in my ground would not pull a 4-16" plow, 3-14" yes and probably a 3-16" but not a 4 bottom. A 720-730 should handle the 4 bottom plow with no problems.

I agree completely...there ARE soils (and Conditions) that will make all kinds of different loads on a plow... My time at the "Plow Days" was probably not all that typical... I had just re-built this 630 with New Mains and rings and a VERY GOOD Valve Job that NASCAR would envy...along with New 15.5x38", LOADED, 3 wts on the left and 2 on the Rt and 300 on the front.. This was NOT any more than it needed, either..!! BUT, it DID pull it and over 7" deep in established Alfalfa and Jack Wax.. IT was every bit it could muster (900 RPM) in 2nd, at times..!! Sure seemed to shake the very Ground..!! What a HORSE..!!! My 720, with 300 lb on the front and New 15.5x38" and a couple wts on each side walks right along with that F-145" 4x16 (here) in 3rd, 7+" deep...sometimes lifting the front..!! It's not an "R", but holds it's own...!

The F145 had a top link sencing unit avaible as did other makes like the Massey Ferguson that I had. Even tho I had it and the tractor a Ford 5000 senced from the top link I lsually kept it in position control instead of using the draft control and top link senceing. Could get better depth control.

What you need the quick hitch for is more depth control than weight transfer.With perfect conditions(level field and all same soil type) it is not as much of an issue.If you have any hills or soil changes you are constantly moving the three point lever for depth control.

All the quick hitch does is move the hitch points further back, does nothing to work with the load and depth control. You would still need a connection to the top of plow mast to the quick hitch.

You don't get it and are not going to.The only way for you to understand would be to try it both ways with a semi-mount plow then you would see the diference.

Guess I sure don't see what you had a problem with...

I HAVE BOTH and use BOTH and don't NEED that upper-Link, with a Semi-Mounted F-145.. The F-145 Semi-Mount WILL pull down on the rear of the tractor, as Load increases..believe me... I do like to have a Gauge wheel at the rear Bottom, just to let it take care of that end..!!
