Has anyone with a 4300 gear or sync. rev transmission done the 50 hour rockshaft filter screen service yet. If so what did you find? Heard of some problems on hydro. models. Screens either becoming torn or dislodged. Thinking of upgrading to new filter.

Thanks,
Al

Was the first year of production for the 4300 1998 or 1999?

Jim,
Sounds like it was a hydraulic oil cooler added to just the HST models. If you still have your owner manual check out page 62. Cooler on bottom picture but not on top. Talk of confusing. Should just ask the dealer to confirm this. Having just got the machine I'am finding out that John Deere seems to make running improvements during model years. Some which are probably important to get done. Having worked in the auto. industry for years just not used to this. Design changes having to be being qualified for years first. I can't imagine with 7 gallons of fluid and all the mass of the gear transmission, rear end, etc that a cooler would do all that much. Does anyone have a 4300 or 4310 with a hydraulic oil cooler?
