I dont think you need that kinda cash to get into these classes. But i would check local rulkes for the class or the sanctioned body you plan to pull with, so you know what and how to build it. Those classes vary a lot. You can also pick a already built tractor for reasonable sometimes. Good luck.
 
FullPull.. TTTPA class is kind of a warmed over Hot Farm class... propably closer to ProFarm... I know there is a hand full of tractors almost finished.. (I've been helping a few guys on the phone almost every night.. haha... ) They are close.. just a few bugs to work out...
Rules are not too difficult, but some tractors will be easier than others.
Basically 466cid, Garrett GT42 (there are certain number housing you need.), max 13mm P-pump. I think they have decided on 4000rpms, but not sure they are going to really be limiting the RPM's. Steel flywheel, 4.2 SFI blanket, side shields, kill switch, tires 18.4 or 20.8x38's or 24.5x32's, ladder bars.. few other basic saftey and general rules.
Once they get a few more tractors out there.. it will make a good class.. They increased the RPM's for this year, and added the steel flywheel, which is holding back some of the John Deere guys, because they are running a wet clutch, with cast parts.. they are trying to get the parts to be leagal.. some should be out soon..

why is there a rpm limit..... that sucks
Click to expand...

ever seen pro-stock??? some of those guys are breaking an engine every pull or every other pull cause of the insane RPM's......


remember you got to pay to play guys........your looking at alot of money just to pull this tractor out of the barn every week........anyone priced a set of cut tires lately, they are by no means cheap, then a good set of aluminum wheels, thats big $$$$, blow an engine apart, remember most of these aint 5.9 cummins engines (some are though) and some parts are pretty expensive in stock form, let alone aftermarket built ones.......
 
Yeah I live right by a guy with a prostock running a sigma pump that wins a lot
if you build them right they should hold

besides our hot farm does not have an rpm limit
 
On the rpm limit.. with the current rules, you do not have to have an SFI clutch, just a steel flywheel.. (which most of the time starts you on the path for a SFI clutch. and the Damper, does not have to be SFI) They are just looking at saftey... And keeping the cost down.. but like any other pulling that is going out the window...
This yr you can custom build the frame.. last yr was stock side frames..
Rules should be in for 3 yrs... (I see someone posted the rules above..)
Bryan

Edit:.. I see they have updated the rules for the SFI balancer, and steel pressure plate and flywheel.. which makes sense, but still not SFI...
