How often to grease mower deck?

[bellweather]

The manual is a little unclear on this. Seems to indicate that greasing should be done each time the mower is used? I grease mower deck & drive shaft CV joint at the start of the mower season...is that adequate?

Depends how many hours your mowing season is. My Woods mower says every 20 hours. If I remember right I think my John deere mower is every 40 hours. Since I only use the Kubota/Woods and JD for mowing in the summer I just lube off the tractor hours.

I have never had a Kubota mower but I would think they should have an hourly schedule for it.

In a word.....No. Some of the linkages that don't move a lot may be fine, but spindles and joints I try to do every 10 hours. Grease is cheap insurance on a very expensive part and really easy and relaxing to do. I'm a bug on maintenance,but I tend to keep stuff a long time and I see a difference.

Kubota machines are meant for commercial duty if any mowers are and the greasing should possibly be done about every forty hours of mowing on an average lawn. That doesn't include the time spend with the loader or just driving but while the mower is running.

I have a 11 year old Grasshopper mower with just over 2000 hours on it and I've not replaced a single gauge wheel, bearing or spindle. I cannot detect even the slightest slop in the spindles even with that many hours. I've absolutely, positively never run it past 8 hours without greasing it. It's easy to remember; it will run 8 hours on a tank of fuel and it gets greased every time I fill the fuel.

Based on this fact, all of my mowers get greased every 8 hours. I've never had a spindle, wheel bearing, pillow block bearing etc. ever fail on any of my machines. I run the same schedule on all of my equipment; dozers, excavators, skid steers, track loaders, tractors etc. You can say I'm wasting grease all you want, but I've never had a failure or wear issue on any greasable component. It seems that any machine I don't own I operate feels loose and sloppy to me. My machines all feel tight and I have no slop.

Grease is cheap insurance..parts and down time=$$$'s

It is just easier for us to grease ours every time we use it than to track hours and stop in the middle of a job. It averages out to about every six or seven hours.

I sure would like to get the definitive word on this as it applies to my Kubota B7800 with belly mower. I asked this question before and got answers all over the place from every use to 100 hours. The owner's manual makes no mention of it.
In defense, I grease the spindles every six or eight hours but would like a better guess. Surely someone must have mention of it in some Kubota manual or maybe someone has first hand info on this topic?
Someone told me overgreasing can blow out the seals?

Thanks guys. Based on what I'm reading, I'll grease more often. It's easy enough to do and like I read, it's cheap inurance.
