Set your hand throttle to 1500 and use the foot throttle for 2100.

We have removed the plastic friction bushing for throttle lever pivot on all these vintage tractors. We replace bushing with oil lite bronze bushing cut to fit. We then put a cut in bushing so it well squesh down nicely with friction adjusting setscrew. This makes throttle lever much easier to fine tune. Have never tried installing any stops. I'd make sure proper constants for tractor and tranny are programed in. Run turbo boost and transmision calibration with everything at operating temperature. Then when in field doing your most common job you can set offsets in transmision controler to give best shift from 9th to 10th and then 10th to 9th. The offsets are manually programable to speed up the shift if it is jerking because it is shifting to slow (basically hitting neutral before next set of clutch packs engage) or if shifting to fast (both 9th and 10th engageed at same time causeing severe load on engine lugging it down a couple hundred RPM for split second). A little playing around with this may yield you a much better shift. Next series of models with 18 speed power shift no problem at all. Next series with CVT another step ahead and programable throttle plus plus plus.

Dan, we rented a DT200A this past fall. It had suspended cab and axle, 33 mph. When roading in economy pedal mode it acted like an engine with a worn governor, always "hunting". It would go up to 34 mph, then slow down to 32, then speed back up. This was all on flat, straight run. Is that the nature of the beast or did the computer need a setting adjustedIJ

Well on a Fendt if you have the mph set at say 33 and the engine rpms too high it'll hunt like that. Idle the engine back to 1700-1800 and it stays level. I know its not the same tractor but the back half including the transmission is the same.

Don't know about in pedal mode and or with the higher max speed with suspended front axle but is normal otherwise. Guys just throttled back a touch or slowed up a touch to stabilize. This can be corrected but it will take your dealers service rep to change a constant. We went around and corrected a bunch one day. Trouble is I don't want to install any refined software for it will go back to surging (I think) Didn't do tractor school this year so I'll have to ask tech if subject come up. I'd like to set that constant with our own laptop. I suppose they don't want us sneaking in and giving it any more speed than what is recommended or legal.

Dairyman, You had the RPMS to high,slow the motor down a little bit until it is not surging. My 220A runs as fast as it will at 1640 RPMS,any faster and it will surge. It wont run any faster,no matter how fast the motor is. Its a stange beast sometimes. I think you almost have to throw everything you know about running a tractor out the window,and start over. They are amazing. IG

IG, In economy mode, you leave the throttle at idle and just push the pedal down. Not sure how I would adjust the engine RPMs to make it act differently. Can take the surge away by moving the dial preset to 32 MPH, but why not go as fast as ableIJ That is the whole point of the fast transport speed. Dan, I have wondered how fast they might go. If one equipped with 42" tires can go 33 MPH, how fast would one with 50" (like we rented) go if you reset the computerIJ Fun to speculate!

you should get your turbo boost and F1, F2, and R clutch packs calibrated and then have your service man print off a copy of the offset cal. page in the service manual so you can play with it in the field. Most instances you can get it to your liking. The newer powershift tractors do not have this shift in it. If you want to drop speed and RPM a cvt is the way yo go, all you have to do is hit a button and it will slow MPH, RPM down and can also raise implement, so about all you have to do is turn the wheel and hit the button again and away you go.

Hey, never thought of it that way, good call. Thanks for all ideas...
