7045 Power Director

Well this is weird. Low range 4 th gear low PD is supposed to be 5.2 mph. 3 rd gear high PD is supposed to be 5.8 mph. I was looking for just a bit more efficiency so I tried the 3 rd high. Buttometer didn’t notice much difference. Got the stopwatch on the phone, it’s actually a little slower. A pass was 5 minutes 22 seconds with the 4 th low, 5 minutes 38 seconds in 3 high. And yes I checked both directions to rule out hills and slippage.

Is this a bad sign?

Engine sound is normal, wheels are steady speed. Pd stays down, pulls engine down more than when in low but not bad, seems normal for each gear, just slow. Doesn’t seem as slow as 3 low would be

I know yours it 7000 just applying what I see on my 8000

Borrow a GPS  from one of your neighbors. That will tell the story.          MACK

Well yeah, I suppose that could be more accurate. However I did my measurement on several passes, both directions, and even a round trip. Right to the second each time. And with a 5 minute time span, that eliminates a lot of the guess work and variables.

I have a light bar on a different tractor, I can rig up power and check. But I’m telling ya, it’s for sure going slower.   

I suppose if it picks up 1 mph in this test, something must be slipping big time trying to use it in that gear. Yet works perfect in 4. Weird.

Update.

Set up markers and got out the stop watch again. Nothing hooked to the tractor, bare tractor, flat ground, but checked both directions anyway for thoroughness.

3 rd high PD which is supposed to be .6mph faster is actually slightly slower, just like in the field

Guess the sticker is wrong?

Well I’m at least owner number two, not counting the tractor jockey I bought it from. So who knows if it’s been apart or not?

Rubber and RPM are as you say.

Time is precious….but I might try to hook up the light bar or something and see if I can get a mph reading, see if by chance it matches a 7050 or whatever.

Shifting like this should show an increase in speed every time.  Makes no difference what the actual MPH is, it should get progressively faster by this shift pattern. at the same RPM's each time.

Um, yeah. I know your point, that’s what I was trying to accomplish in the field. Trying to go just a bit faster, seemed like the tractor could do it. 4th high was too much.

My point is, if the Mph happens to match that of the other model, maybe it indicates the tranny was swapped. Not that it really matters or definitively proves it, just an interesting piece of information.

One thing is for sure, it doesn’t do what it’s supposed to do. But doesn’t seem to be bothering anything either, so idk, other than just keep an eye on it.

Wouldn't it be best to run in "hi button" so it's going straight through, instead of through another set of gears? I realize you may be looking for a particular speed, but I'd think you'd want to choose a gear that lets you upshift to hi button on the pd, giving you a downshift if needed for tough spots of turning on the ends.
