Tractor Puller (Modified)
Discussion
I know that there are a couple of guys on here into tractor pulling, soi I thought you might be interested in my new project "The Bounty Hunter".
The chassis started life as the "John Bull", built and run by Chris George, a very well known and highly respected engineer and puller. He ran the tractor with two Rolls Royce Gnome turbines, I bought the chassis without engines and plan to fit one or two 27 litre V12 Meteor engines, and run it int the British Tractor Pullers Association 2.5 and 3.5 ton class. More updates to follow.......watch this space......

Good stuff, I presume all the additional weights are required for both chassis balance and class regs?

Yes thats right, the chassis has weight frames on the front and back as can be seen in the photos, as well as a weight frame in the centre and and also the centre of the wheels have weight carriers too.slinky

Is it in the rules that the tyres have to be worn out? Or do they make you fill-in the holes yourself if you use new ones?
Those tyres are in really good shape! If your commenting on the black patch on the left side tyre, its a patch of oily tar which has been rolled through, or were you expecting a puller to use stanrd tractor type tread patterns with loads of grip? Pullers don't have much in the way of tread, as grip = broken driveline bits, traction is gained by friction, leaving the line with 80 - 100 mph wheel speeds. Me? Mental..........just having a good time, 'cause life is short. I now have a dilema, there is a 27 litre V12 Meteor (the tank version of the Merlin spitfire engine) and a 30 litre V12 Continental (air cooled tank engine) for sale at a reasonable price, both reconditioned in crates. The Continental is heavier than the meteor but has slightly more horse power. I am looking for around 1000 - 1200 hp. The Meteor is fairly local but we would have to go to Holland for the Continental.........problems, problems.

wasnt it carrol shelby who said "there aint no substitue for cubic inches"?Yes I've seen that tractor, and you'll see some of our southern ones next weekend, today I was in the back of a trailer loaded with 2 modified's (Mustang Sally MK2 which has a V12 Transmash 38 litre diesel, and Little Gold which has a V12 Meteor 27 litre petrol)which will be pulling at Edzell, near Brechin next weekend.
I don't think I'll ever have enough money to put one Keith Black on it let alone multiples. V12 area/Tank engines are relativly cheap really.Update
The following pictures are of a 27 litre Rover built Meteor V12 engine, which I recently bought to put into the tractor chassis. The engine was originally in a Centurion tank, and I bought it in as removed condition. We've had the top and bottom off, and saw nothing too scary. In standard tune, this engine will put out around 650 - 700 bhp, which is enough to be going on with, although there has already been talk of Turbochargers and Methanol........watch this space.
Weighing in at around 750Kg, the seller loaded it onto my trailer with a loading shovel on the front of a tractor, but it was a bit of a bugger to get off the trailer, and into the workshop, my 2 ton engine crane picked it up no problem at all, but once the engine was in the air, there was no way, short of attaching the car, that we could move the crane! Anyway, after a couple of hours sweating and swearing, we managed to get the trailer out of the way and put the engine on the workshop floor.
Along with the engine, we have managed to get together nearly all (I think) of the componenets needed to get the tractor actually up and running, we have a 10 inch 3 plate Crower clutch, complete with bell housing (no pictures of that I'm affraid, it's off having some work done at present)but we still need a drop box which will allow us to overdrive the clutch x2 engine speed. Increasing the input speed will reduce the torque transmitted from the drive into the chassis, and allow the centrifugal clutch to perform more efficently.
Calcuations have been made (by those with infinetly more powerful minds than mine) and the drop box is being designed as we speak.

If I ever take my tractor home in that condition, the resulting costs of the rebuild would surely end in the divorce courts

As a drag racer the phrase "there's no substitute for cubic inches" comes to mind!
Also the clutch is a Crowerglide, used until fairly recently in nitro Funny Cars.
If you need any help with that post your query through the Drag Racing page.
