Thanks davkir, that gives me hope that maybe this is normal. I'll have to test it out this weekend on a snow covered driveway and a cleared driveway. I didn't think that dry pavement would affect 4wd when not turning but maybe it does. If I can determine that what I'm feeling is normal for this tractor then I'll feel much better.
Rougher in 4WD, normal?

My 4010, which is the same weight as your 2305 but geared differently because of the way the wheel shafts go straight out for greater clearance vs. down like yours, sounds rougher in 4wd on paved surfaces. This is because the front wheels are designed to go slightly faster than the rears. This is tougher on paved surfaces.
On pavement with snow, you won't notice any problem. The front wheels can overslip a little bit on the more slippery surface.

Well I plowed today and I'm still a little uncertain as to whether the rough feeling is normal but I feel a bit better after davkir and RalphVa's posts.
Driving down the driveway on top of the snow before I plowed I didn't notice any vibration. I did notice it after I would plow a section and then back up on the same plowed path. So it feels strange to me but for now I'm going to assume it's normal and see if I notice any change over the rest of the winter. Most likely it's normal(I hope).

As was said above, that the front axles on 4 wheel drive tractors are designed to turn faster than the rears. I have driven my small 770 and even full size field tractors and they all seem to make more noise on high traction areas with the 4 wheel drive turned on. If you are really concerned I would talk to your John Deere mechanic. If there is something wrong its better to get it fixed now than to have other parts break later.

Hi:
My 2305 with maybe 140 hours on it seemed 'rough' and a little noisy in 4wd also (worse on hard surfaces). Not horrible, just lounder than I remembered. I changed the front gearcase (First change unless the dealer had) and put synthetic gear oil in it and it quieted it down quite a bit. I saw a few metal filings come out but nothing major so I think maybe it was just in need of a change.
Question for someone that might know? Do the extreme pressure additives (Phosphorous, etc.) they put in gear oil break down over time? I so how long?

Seeing as your question has not been answered , i'll give you my 2.02c .
Yes they do break down over time , how long i don't know . It depends on many things .
What i do is change my oils twice a year , once in June and once in December . You can't forget this way , June is the end of the finacial year and December is the end of the year . I am a contractor that works the gear hard . You may get away with doing it once a year . Oil and filters are cheap , bearings etc are not . Take the guess work out and have peace of mind .
