JC Posted August 29, 2006 Share Posted August 29, 2006 How much can a tractor physically pull comparative to its HP........ ie; What weight could a 135HP tractor manage, a fastrac 1135 or a Case MX135 for example?? (both 135HP?) Quote Link to comment Share on other sites More sharing options...
Deere-est Posted August 29, 2006 Share Posted August 29, 2006 Torque plays a big part and also load resistance. Still got no idea though \ Quote Link to comment Share on other sites More sharing options...
Lord Ferguson Posted August 29, 2006 Share Posted August 29, 2006 Traction as well of course... I guess that's an impossible question to answer really... HP is revs.. where as torque is grunt basicly... I do know tug boats as measured in bollard pull... I guess it's a level playing field if they are all in the water... but with tractors there are too many variables.. \ In summary... I havn't got a bloody clue :D Quote Link to comment Share on other sites More sharing options...
Mac Posted August 29, 2006 Share Posted August 29, 2006 Depends on tractor weight, tyre size, 2 or 4WD, type of 4WD, the driver and ground conditions. Silsoe Research before it closed conducted standard tests under standard conditions that could be used to compare different tractors. Similar tests were/are conducted on mainland Europe and USA. A good driver who carefully adds weight to his/her tractor to match the implement will acheive the best output. Quote Link to comment Share on other sites More sharing options...
allis8550 Posted August 29, 2006 Share Posted August 29, 2006 It's got to be down to weight and grip rather than power, for instance a 5hp traction engine would pull a 120hp tractor all over the place on the right surface. Quote Link to comment Share on other sites More sharing options...

Similar to crawlers then, at college we had a 33hp Bristol Taurus crawler, she's just pull 4f in nice soil but an MF230 wouldn't pull 3 furrows. DICKY showed me some pics from NZ of an event which the name hascescaped me but they strap a concrete lump to the pick up hith of various sized normal farm tractors and tow it over a set distance from a standing start. Fendt's were getting whipped by similar sized Deere's with powershift rather than stepless transmissions. Quote Link to comment Share on other sites More sharing options...
Lord Ferguson Posted August 29, 2006 Share Posted August 29, 2006 Interesting post this... I guess the concrete slab pull is a good test PROVIDED the ground conditions are always the same (even down to temp of track I guess) And for John Deeres and Fords.. they need a hen on it's nest Quote Link to comment Share on other sites More sharing options...
SPN Posted August 29, 2006 Share Posted August 29, 2006 It is a function of gearing and traction. If you have a low enough gear you can pull anything, provided you can get traction. Zetor Crystals were always amazing when it came to pulling trailers out of mucky spots. I've never seen any other 2wd that could put the power down as well as a Crystal.

MJB1 Posted August 29, 2006 Share Posted August 29, 2006 no he'e not marky , i drove zetors for dawes , 9045, 14145 & 12545 , with the duncan cab fitted (the later crystals) & they were pretty much unstoppable , the 14145 would pull a loaded 2000gal tanker & five leg flat lift injector at a depth of 16in on the hills around totnes & to be fair , they were hills that i wasnt over impressed to be having to drive on but the zetors went up & down everywhere , , the 1884 were stuggling as were the fendts , thats why we had the zetors in , but soon as they hit tarmac they fall to bits give them their due , they were pretty awsome to see working & fitted with the michilin MX's pretty unstoppable Quote Link to comment Share on other sites More sharing options...
Tractorman810 Posted August 29, 2006 Share Posted August 29, 2006 yeah still a lot of the older zetors down this way,2wd and 4wd and they go places a lot of the big stuff wont,especially over the moors ,just can't stop them, even loaded up Quote Link to comment Share on other sites More sharing options...
Lord Ferguson Posted August 29, 2006 Share Posted August 29, 2006 Blimey boys... I never realised that... so why are they such a joke then... Sound like good machines to me... they seem to have the earlier "skoda" image in the farming world - or is that just around here... where things are flat and we have plenty of LONG LONG droves Quote Link to comment Share on other sites More sharing options...
Tractorman810 Posted August 29, 2006 Share Posted August 29, 2006 don't know mate, like you say skoda image, i also see a lot of the older fiat 2wds arround this way ,on smaller farms, the ones with the duncan style cab,they seem to get most places to without to much hassel Quote Link to comment Share on other sites More sharing options...
SMurF Posted August 29, 2006 Share Posted August 29, 2006 I know of early zetors that used to break in half when ploughing due to poor castings Quote Link to comment Share on other sites More sharing options...
MODELFARMER Posted August 29, 2006 Share Posted August 29, 2006 This might help in some sense When we bought our dump trailer Any dealer we went to reccomended 8to 10 HP per ton In other word a 120hp tractor is recomended to pull a 12 ton dump trailer which is why me old man bought the 12 and not a 14 :'( :'( :'( :'( aw well i'll put greedy wings on her sometime ;D ;D ;D Quote Link to comment Share on other sites More sharing options...

MODELFARMER Posted August 29, 2006 Share Posted August 29, 2006 Ha ha oh yes like the 6620 is sittin at 170+ so she never knows its there!! The 3050 is at 140 -145 so shes easy too NOW THE MF 362 . . . . . .62 Hp . . . . .. dad pull home 11ton of wheat with her + weight of the grain trailer so she'd do too just a MUCH slower way home!!! OH and no trailer brakes \ \ \ Quote Link to comment Share on other sites More sharing options...
Lord Ferguson Posted August 29, 2006 Share Posted August 29, 2006 Christ.... my Bailey 8t trailer need 80hp then... Mrs F... I need a 595 NOW Quote Link to comment Share on other sites More sharing options...
Pingu Posted August 29, 2006 Share Posted August 29, 2006 We aim for around 10hp per ton bar odd occasion when down on tractors so will have 270hp on 14 tons , but most machines we've found will pull on tarmac more then you expect like our 106-54 will pull the 14 tonners with no real problems. It's when you hit wet conditions that it can really vary on the slippery tracks even the 735 on 14 tonnes will struggle. It all depends on conditions and what the machine can actualy do we've found Quote Link to comment Share on other sites More sharing options...
archbarch Posted August 29, 2006 Share Posted August 29, 2006 its all down to the driver at the end of the day with modern tractors/machinery the skill is being lost setting the tractor and implement is a worthwhile excersise. its nice to have power but i see so many so called ploughmen making the job look hard work if only they spent a few minutes they could pull another furrow use less diesel and do a better job Quote Link to comment Share on other sites More sharing options...

MJB1 Posted August 30, 2006 Share Posted August 30, 2006 think i always messed about with the settings all day long to get a better job done & when you've got it right , you feel better for taking the time to do it as well as for the zetor's marky , basic & unreliable , on the whole , but like anything , any machine will go wrong if not looked after properly , & most zetors were stockman tractors anyway , although there is a farmer nearby , who has a couple of 6000series JD & ford & a mf 698 T , but a zetor 8045 still runs the jag forager at silage time !

Light Land Posted October 1, 2006 Share Posted October 1, 2006 what a good thread to read,top marks to FP for starting it. I realy think for road work you can can get away with useing a smaller or lets say under powered tractor for the job than when working on a paddock because grip is not realy a prob on a road. I often pull 28 ton of potatoes on the road with a 140hp tractor (1455xl) with no prob at all because the road has very good grip and the air brakes pull me to stop in no time.
