Looking to tune our 600 quad track whats out there we had a steinbauer on our old 500 it seemed to work well. Don't know how safe would be to take it up over 700hp.

Rocky gets a lot of their new tractors tuned. Steinbauer was good years ago. Seem to be lots of trouble with the Steinbauer now. Some of Rockys big customers have 5 seasons on the big 700+ hp tunes. So far so good. I am sure that it is going to shorten the lifespan some on the tractor. Remains to be seen how much.

I have considerable experience with that combination. I’m not sure quite what my own opinion is, the tractor has had a considerable repair history, but based on incidents of other much lesser powered tractors having the same issues it leaves some uncertainty for possible remedies.

My instinct tells me that extensive power shifting the larger Quadtrac’s may work harden the axle bearings by breaking through the oil film during pressure spikes, there’s no way to know. But, those bearings can wear until they are loose causing the axle seal to leak. It is unusable with a leaking seal since the entire assembly has hydraulic oil flow though it. Thankfully the return oil is filtered.

I’m guessing the tractor has about 2000 hours pulling a large drill, including slow passage though a lot of drains and about 1000 hours on a scraper with lots of power shifting. The other 1000 hours is likely just idling and transporting. If I had it all to do over again I would try to just throttle down more to get the drill through the drains and go to full throttle when the cart starts coming down the slope. It’s just the nature of the throttle program, even with the power module, that it needs to be wide open to produce maximum torque at lower RPM. Actually the outfit is heavy enough to control the acceleration with a bit of throttle control practice. Sometimes you just have to ease it back a bit again if it comes charging out too fast.

I would only gamble what you can afford to lose in any decisions in both setting or operating such an expensive machine.

I would not get a chip or Steinbauer for that, only custom tuning can provide the maximum results and reliability you need. I talked to a lot of guys about this and they all got custom tuning done for all sort of equipment. Looking into this and comparing prices and feedback I go with these guys for sure. tuning24.org From what I know they are for 15 years in business and provide a lot of tuning to the big names, now they sell directly to the farmers. Yeah saving money for ones

Tune - from research I’ve done, on the newer stuff anyway.

Heard good things about Reimer Tuning
