Personally, I would look for something else, but if it's a 4930 that you want, check the hydro hoses closely. They have a tendency to rub through in many places and will certainly be suspect on a machine with those kind of hours.
Excellent point. Some sprayers spend much of their life idling or running up and down the road racking up engine hours without much wear and tear.look at spraying hours. not engine. our sprayers idles more than drives lol
Driveshafts flying apart is a common problem with Deere sprayers but seems to more of an issue with the 4830 than the others. I know of MANY and all of them have been yoke failure. Seems that jd "engineers" thought it a good idea to weld the balance weights to the cast iron yoke rather than the shaft and this causes the yoke to fracture at the weld. I've had three such failures and know of many others. It's not nearly as common on the 47xx or 49xx though. Have never heard of a u joint failure but I'm sure it happens if not serviced like any other u joint.Those bearing cups on u joints are famous for not taking grease. Very spendy to replace when they let go and cause a lot of damage. Grease em and make sure they all puke out grease.
Was that an oversight for factory not to put in filters or is there a flow reason that they do not have filters? I would hate to starve the pump just cause oil was restricted.Rather than a "repair schedule", I'm planning to add filters on the return lines so if a wheel motor piles up, it doesn't contaminate the entire hydro system. Then just fix when fail. I haven't heard of many wheel motors failing on JD sprayers so I'm not TOO concerned but since I have to keep this sprayer for quite awhile (NO WAY I'm paying $400,000 for a new one), I am going to try to mitigate potential failures, and, in this case, try to minimize/eliminate collateral damage from a failure. I'm also going to built a skookum scatter shield for the drive shaft so when (not if) this one flies apart, it wont beat the **** out of everything around it.
