Does the flashing dashboard on the Fastrac not get on your udders .It would distract me thinking there was a fault every time i looked forward ..Its doing well though in greasy conditions
With a bit of thought, they could have fitted 38" wheels on the back without comprising lock, have a look at a Claas. If they had done that they would have a real good tractor to sell. Sadly Jcb just don't seem to be able to build anything without making at least a couple of glaring design flaws. So annoying
Where do you farm?As I said, our endrigs are very steep..Some places you can barely open the baler or it will tip. Much less than 30 psi and the tyres will be off the rims. All this talk of dropping pressure is fine in normal conditions but no good to us. The contractors 650x 42's are on their limit sometimes and they have a lot more capacity.
Fastracs will sit down and pull as well as anything else. You just need to spend more time setting them up, getting the weight in the right place and making sure tyre pressures are correct. They are a lot less forgiving of lazy operators than normal tractors.
Exactly - secret with Fastrac is to ballast correctly . You can have too much weight on the front of a Fastrac compared to a conventional tractor - too many drivers just pile the weight on the front and all it does is have an opposite effect after a point.
The rear deck weight option is under-utilised and is the place to add weight to make them grip and pull.
Can tell the people who have operated a fastrac as opposed to think they know how to on this thread. .

Can't see making much odds to the rear diff loadings, The final drive will gear it down.. Then the 38"wheels will gear it up again. Only a bit more torque going through when comparing a 30 inch slipping and a 38 inch gripping.. not a big deal. If your talking about the casing and suspension loadings, bigger wheels are small fry compared to the stupid pickup hitch that collides with standard trailers and tries to rip the back axle off the tractor
I don't understand why they would sell one without a deck weight.
I wouldn't buy one without it.
1 of our 4220's is purely for trailers, no front linkage or deck weight. Not neededI don't understand why they would sell one without a deck weight.

Our 4220 pulls a Dale Ecodrill 8m on the pickup hitch. With 900kg on the front, we have 3150kg on the rear axle and 3100kg on the front. The weight is important for this reason.
Are you saying your tractor weighs in at 6.25t including 900kg ballast?
5.3t on front axle and 5.9t on the rear axle with the drill full and the weight id say
4220 on it's own weighs just over 8t
The south side of the black isle.. plenty of good ground about here but we are some of the steepest around. Took a contractors 215r to it's knees with 4 furrows on the back and that was with a loader and a stone graip with the ballast thrown in the graip! Even the ontop limespreader dug in on the worst bits..Where do you farm?
Sounds extreme.
Been huge success for jcb 4000 seriesDon’t knock a 4220 until you’ve tried one. Remember nothing is perfect.
