I have purchased a Model 80 4 Bottom Plow. I found the book for it on eBay and the missing coulters at the local ag dealer. Here's my question to the group. This is 4 Bottom plow at 16 inches. In my soil my John Deere 5320 (65 hp) WILL NOT pull all four bottoms so I dropped number 4 off quite easily. Here's the question for ya'll, What weight tractor and what hp pulls 4 bottoms comfortably in pretty heavy clay based soil typically found in upstate New York? Share if you'd like what HP tractor you pull three bottoms with. This all started when I saw photos of a D17 at 50hp pulling 4 bottoms.....I'm suspecting that it's a much longer tractor but its only slightly heavier than my 5320..... Thanks for your replies.

I have pulled 4-16" with our D19 with no problem, and have even pulled it with our D17, the D17 just plays with 3-16", around here we have heavy black dirt. I am assuming that your JD 5320 is in a "compact" tractor catagory, yes it has 65 PTO horsepower but they are pretty light on their feet, I think you might want to drop down to a 3 bottom or even a 2 bottom to do a better job. ------------- Unless your are the lead horse the scenery never changes!! |

Back in 1968 we pulled an 84 series S/C plow with a series I D17 gas then in 1970 updated to a 180 diesel and an 84 series 3 point plow. Also pulled a 5x16 semi mouned JD plow with the 180. Our 180 had the tires loaded plus segment rear wheel wts and 3 bar weights on the front. ------------- Fred Dunlop, G,B,CA, WC,WF, 3 WD45`s,gas, diesel and LP,U,D10 series III, D12,D14,D15 SERIES II,D17 Series IV in Gas and Diesel ,D19 GAS and D21,170 185,210 ,220 an I-600 8070 fwd, 716H and 1920H |

We pulled the 3 bottom in sod that was plowed a couple of years ago. It did well. 3 bottoms in sod with brush roots with no coulters was TOTAL Waste of time. Also the soil was dry - unusually dry. We're going to try it with 3 bottoms with coulters and the plow properly adjusted. Failing success we'll drop to two. I agree with you - it's probably NOT an HP issue it's a combination of weight, traction and the length of the lever due to the 5320 being relatively short. I am getting 400 pounds more for the front...... In the end it's the perfect excuse to buy a bigger tractor  . Thanks for the feedback.

it all depends on the type of soil. a d-17 would have a tough time pulling a 4 btm. on our farm. we always pulled 3 btm's with out 17's. not for lack of power they would spin out with loaded tires, power wasn't an issue. our d-19 pulls 4-16's nice. makes it grunt in 3rd high in 2nd it powers along effortlessly. alot depends on different factors. my 2 cents ------------- D-19 gas w/f-sold 185-d yr round cab 95 mustang gt 5.0 86 mustang 5.0 coupe 3 99 f-250 7.3 4x4's 96 f-250 7.3 4x4 |

I agree - based on the fact we plowed pretty easily with 3 16's in soil that was turned recently. The fields that have just been mowed for years with brush and tree roots was a challenge. We found used coulters now and the shin for the mole board so we'll be in better working order for cutting sod and roots. Like I said in an earlier post - I guess I'll just have to get a bigger tractor - oh dear ------------- Ken Pleasant View Farm http://www.pleasantviewfarm.com |

That JD should weigh in around 5,000 + lbs which is close to what a D17 weighs. Add some weight and try again. ------------- Charlie '48 B, '51 CA, '56 WD45 '61 D17, '63 D12, '65 D10 , '68 One-Ninety XTD |

there are a lot of variables, weight of tractor, soil type. compaction, ect. i have a 5210 and believe me even though they say it is 45 hp, 2x16's is all it wants in stalk ground and when i move to sod i go with 2x12s with the 5210, while i can take a old 46hp model 961 ford and pull 3x14s right beside it in the same field now i know that the 5210 is not a 5320, but they do run the same enjine a 179 ci diesel, and the same transmission,the 5320 is getting its extra power from the turbo,there will be times when the 3x16s will give the 5320 more than it wants
the tractors pulling 4 bottoms in black prairie land, like the corn belt, will struggle to pull 3 in hard rocky red clay, like here in central ky.
time of year, and soil moisture also comes into play, a piece of ground that you can easily plow in november or febuary will pull the crap out of a tractor after a long dry spell in the early summer.
by the way 4x16s will work the heck out of my old 4020 jd, and i want even think of using one in sod with my 6060 allis, (63hp) , while i can run with 3x16's
so my suggestion is to find you a set of 3x14's or go ahead and trade the green toy for a real tractor, ------------- i like old tractors of all colors |

Thanks for the nice post - even with your quip at the end on trading colors. Perhaps, I'll build a 3-Point hitch for my 1929 Farmall Regular (Original Owner). If interested you can see it in action - steel wheels and all at my YouTube site - http://youtu.be/f2_smfIfreE Thanks again for the feedback. ------------- Ken Pleasant View Farm http://www.pleasantviewfarm.com |

An old employer of mine said that you need 20 HP for every bottom on a plow. I told him he was painting with a wide brush when he made that statement. Yes I think 20 HP per bottom would pretty much cover any plow with any soil condition but like others have said there is a lot of variables to consider. We had a 59 D-17 that could pull our 4X16 plow in black dirt. The D - 19 did not even know it was back there. ------------- You only need to know 3 things to be a plumber;Crap rolls down hill,Hot is on the left and Don't bite your fingernails 1964 D-17 SIV 3 Pt.WF,1964 D-15 Ser II 3pt.WF ,1960 D-17 SI NF,1956 WD 45 WF. |
