Hi I will have to disagree with the do not wash comment, I have been doing hay for more years then I care to admit and I have had, owned 3 round balers. I have used both air and pressure water to clean all 3. after I pressure wash I let dry and then go back and oil ,grease and lube everything that's needed. I then store or park the machine inside out of the weather, the machine is I might add serviced for any and all damage if there is any. I do very little of that ,maybe a pickup tooth replacement at most. When it is in shelter It is ready to go for next years work ,but as a precaution I regrease , and lube ,oil etc everything again, before I start to use again including the chains etc.I then turn it a few times by hand with a large wrench etc to make sure everything is working correct. I have been in the hay sales business for 25 -30 years and not one bearing failure . I have baled as many as 600 bales 4x5 ,1000 lb the first time around and average 250 -300 the second time of second cutting. I no longer do that much because of land issues etc but I still bale on average of 350 a year. not 1 bearing problem! I my self like to maintain my investment and I have had others say no water ..... its will ruin the bearings ..... well I will have to disagree big time .I like clean equipment ,it looks good ,easier to service when needed, and when sold it sells better. Just my .02cts. have a good 1
