    Ok, we dont have much for power to the tracks i have confirmed the rabbit turtle mode is working (thanks to here) both tracks seem to be of equal power, as it warms up it is noticeably weaker it will push OK with both but will not turn just one in either direction and in dirt it will only try to turn on its weight with sticks in opposite directions, this has been slowly getting worse in the last couple of years. Pressure check where and how much and adjustment location? Hydraulic Fluid & filt. changed every 1000 0W40 used as it can get cold in Atlantic Canada. Thanks

    Have you had any luck with this issue? I purchased a 304.5 and noticed a similar issue. One thing that I have noted in my case however is that the power to the tracks seems very good upon first starting the machine. Then it seems to taper off the longer I run the machine which leads me to believe the problem likely has to do with the oil heating up. In either case though, running the tracks at the same time in the same direction still appears to work ok. But turning (with either 1 track or both) usually results in no movement at all once the machine has been running for a while.
