Well it should have somewhere around 145 but more then likely it was tweeked and could be over 200.

1486 has about 145hp PTO and 126hp drawbar. If its been turned up much past 160 the first thing you want to do is set it back. They can easily acheive 200hp but if operated long USING that power you'll have all kinds of head and transmission problems.

Hummmmm m, now lets see mine has been at 250 for 5 years and my buddys 1066 is at 250 for the last 5 and for some reason we have not had any problems yet but i am sure that they will surface and then i'll just have to fix em . Along with my Dodge cummins set at 350 some day it will break something and i'll have to fix it .

Tractor Vet:
How many hours are you two putting on these tractors, and what are you doing with them. In short, are you putting long hours on them under load?

They are used for tillage and running a two row chopper and trust me we take no prisnors . Most of what i have seen in the rear ends oif turned up tractors is the fact of turning under load with duals and useing the brakes this make the side gears work harder and then they gull up and then bang the rear is out . As for the transmission after time they will ware the teethe and on one tractor and i never checked it ithe gear teethe were starting to fold over. but this tractor was a real pice of junk that we rebuilt for a guy and between the mechanical and tires and paint he end up with well over 17000 in that one but hey who am i to say it is what he wanted and he still love his 1066 and treets it like a baby it is always washed and waxed and still looks as good as it did when it left the shop and that was 6or7 years ago and it does get the bag run off it.. Years ago and i do mean years a go the man i worked for bought the first 806 sold in the state of ohio and my uncle bought the second one sold after driving old G.F.'s and they were both turboed at a couple days old my uncle's was runnig 165 plus H.P. and did so from 1963 till 1970's when he got bit by the Greene bug and traded it for a 4320 and a 4020 , and after putting the 4320 in the field plowen and found that it would not even pull like the old 806 did he was a bit upset .

1486s were notorious for bull/pinion gear failure if used for heavy work with duals.
Simple case of design overload.

That and the silly idea of using Hy-tran for a immersion gear lube :-(


Sounds like we have a happy dyno some where, been there done that.
A 1066 that is running 3000RPM and shows 250HP when pulled down to 2400RPM is not developing 250HP. The HP reading needs to be taking @ approx. 2800RPM (or 250RPM below high no load idle speed) not the factory rated speed.

I've been working on tractors for many many years and I can make a 90 HP 806 show 175hp if I want to play with the dyno.
In any event if the tractor was actually developing that HP and the power was being utilized properly with duals/fluid/weights (slip held to a minimum) the powertrain would fail in a fairly short amount of time, to say nothing of the overheating of the egt, engine oil and cooling system.

And who is to say every dyno is true like the one at the Deere dealer will show 40 H.P over mine and the one from the Joint Vo. school showes 12 less then mine , These are just numbers for braggen, wrights. , just how many Ft. Lbs . of torque , well i do not have the chart to convert and i do not have the math skills . It is the torque that does the work not the Hp. that is like sayen sae. Hp. I could just see one of the 250 hp. v6's in one of the cars of today being put into a tractor and put to work. it would fall flat on it's face but go back to the good old days and stuff a 460 ford or a 500 inch caddy into a 706 and see what happens as the old 460's made 500 ft. lbs and the caddy did a littel better. they will work.

Good point on the calabration of the different dynometers!

I agree with you also on the torque - Hp thinking.

I get a kick out of these newer 4X4 tractors and the small (relatively speaking) engines the manufactors are using.

Just for a example....Sure you can run a L-10 Cummins @ 300+HP in a truck and get away with it because the engine is on duty cycle of 40% or less. In a farm tractor that same engine is running on a 100% duty cycle and is working over 200% harder then in a truck. It's no wonder they have problems crop up.
Set that same engine @ 200HP and it will run many many trouble free hours.

Way back when Hector was a pup and he died 25 years ago i had a 1977 I H 4300 semi tractor with a 350 small cam Cummins and since Detroit has never built a car fast enough for me i always had to make it better well that followed me into the trucking and i had to make that Cummins run and did i ever , we never did get a true Dyno reading on it as the day we did have on the Dyno they just got done doing a new experimemtal KTA 1150 600 hp and had turned it up 20 % and they layed down 475 hp at 55 MPH then they put mine on and in 12th gear of a 13 speed we had 478 hp at 65 MPH and only had reached 34 lbs. of booste when she broke the chain and went out the door and under full load i would get 68 lbs. of booste she wasn't even breathen hard , that truck would take 115000 lbs up over Bald Eagel on I 80 at 72 mph. and this turned up 550 Cat that i am driving now has a hard time with 92000 up the same hill at 62mph. That old 350 ran like that for 385000 miles before eating a piston Sooooo we just rebuilt it and went back at it till i had enough of the trucking.

Know exactly what you mean about the Cummins....
Got what used to be a 350SC in a 4070A.

Fun to see the look on the guys driving the fancy newer trucks faces when that 30 year old truck runs right past them like they are standing still.

Only trouble is the damn flames out the stack burn the tarp on the hopper!...lol
