Cat Dog 2

[nickzdumb]

look at that kid he is a champ does he pull it?

[NathansBackwoods]

It sounds so mean for being so small

[sadjafff]

how manny horsepower does it have its sick

[82Hellbilly]

kingkong1469,

You are a tard. A 4455 is a full size tractor. It is probably a 430 or 420 hood that has been stretched.

[cumminspower10]

Thats or a 55 series JD Compact hood.

[kingkong1469]

all it needs is a fat chrome pipe

and the hood says 4455 so obv its not a 430

[Slooter3s]

what motor is in this tractor?

[cumminspower10]

is that a 430 hood?

[76plymouth]

Why the hell is that guy spraying either into the intake if it is already running?? Idiots!

[justanamelol6969]

too keep it runing sometimes they dont like to run on there own

[DieselDoc83]

The tractor has so low of compression pistons in it that you have to start it off of either to get it going and let it pick up sometimes it takes a whole can on a cold day to get it running

[novakane87]

@DieselDoc83 Really? If you lowered the compression in the engine, wouldn't it loose power?

[douger0500]

No..... Static compression ratio's are still really high. Due to turbo. With lower compression they can run 120 pounds of boost versus 50.  More air means more fuel you can burn. Meaning more potential for power.

[DieselDoc83]

@novakane87 Not in a diesel...you have to remember a diesel runs on fuel and air..the lower the compression the more air you can pack into a cylinder which means when ignited by the fuel the more power you have because you have more air..just like putting a turbo and cooling the air with an intercooler it pushes more air molecules into the cylinder creating more power

[novakane87]

@DieselDoc83 I thought compression ratio is the volume displaced by movement of the piston vs volume at top dead center? So, if the ratio was higher, it would squeeze the same amount of air into a tighter area just before combustion?

[DieselDoc83]

@novakane87 I can see you havent been around pulling if you shave a piston from 18:1 to 15:1 that means theres more area in the cylinder..inturn means you can put more air into the cylinder which produces more power its not rocket science and dont try to over think it..diesel engine equals lower compression more power a 12valve cummins truck piston is 19:1 marine 12valve is 15.3:1..truck motor puts out 215hp...marine engine puts out 370hp and alil fuel difference not much

[novakane87]

@DieselDoc83 No, I do not tractor pull...? Just asking a question...

[cameron947]

@DieselDoc83 A 12 valve cummins truck engine has a 17.5:1 compression ratio not 19.  and the 89-93 have 160 hp, 94-98.5 can have either 160-215 depending if there a manual or automatic. The marine engine have bigger injectors and different spray angles compared to the trucks. marine 155 and truck in 145.

[cubcadet86]

i agree

[farmboi27]

fto spool the turbo it would trun with out the either

[kpshc707]

noob

[TheWinchestermag]

there probly tryin to get the air out of the lines

[ashho56]

@76plymouth your the idiot. thats what its running off of. ether, or starting fluid. IDIOT

[Jason1Pa]

LOL Just like the real thing only smaller!!

[asianstyle123]

holy shit no wonder our atmosphere had so much pollution

[arcticcatzrw]

fuck you treehugger123

[jacobhorsnell]

how much do these weight?

in canada we have a class called modified lawn tractors. we mostly run bike motors like zx12s and also some snowmobile motors.

one guy tryed to build a deseil one using a kabota motor, but it wasnt turning like these do.

im just wondering because i would really like to build one.

[mann56]

are you spraying eather in it

[DanielJaegerFilms]

does that kid drive it at the pulls?

[tractorking93]

thats a serious machine

[kpshc]

what engine is in that thing it must be small

[brotherstoy]

it is an vw 1.9 tdi higly charged

[tpvalley]

Is that a fact? excellent!

Theres one with a peugeot HDI 2.0 engine and with a mechanical P-range fuel pump on here aswell.

I think thats ether hes spraying constantly to keep it going!

[brotherstoy]

irun the same in my gardenpuller about 400hp at 9000rpm

[Pulling44]

this tractor is from germany

[rspeaksup]

Well they need to come to America

[dubb5033]

man, those are cool. where do you pull those at?
