Thanks Dan, mine's a 2011 which says grease drum bearings daily, I'm thinking of using lithium but thought it best to check what works for others.

Wow daily might be less than an hour chipping. I didn't see a JoBeau recommendation so I thought about it from a bearing point of view, in most roller bearing applications 50 hours isn't much eg 2500 miles on your car wheel.

 

I grease my stump grinder bearings daily, theory there is to push dirt out with the over greasing.

 

I'm just using Comma High Performance lithium grease

Sounds like the way to go, thanks. I'm assuming this vintage doesn't have sealed bearings but still an unexpectedly high level of greasing.

Lithium grease for bearings, moly grease for pins and bushes.

 

'Sealed bearings' where there is a grease nipple just refers to the seal which keeps the grease from contamination. Usually plastic, sometimes steel for heavier duty applications with a risk of damage (flail mower picking up wire etc- although there will usually be secondary welded guards to prevent this).

 

You won't 'pop the seals by overgreasing'. Grease will easily get out around the edges, especially when viscousity decreases with heat from friction in use. Therefore, it is sensible to grease a bearing after use, to replenish lost grease, and when the housing is warm to enable the grease to flow better.

 

Seals are there to prevent the bearing from being easily contaminated, and perform this function well.

 

To prove all this, see the below pics I just took for you. A typical bearing housing assembly for a flail or chipper. 'Triple sealed' as it says on the box. Ten pumps of grease, cold, and it starts oozing out- but there's no chance of those seals 'popping out'

HC dismantle today in a tight little back garden with a horribly long and awkward drag to the roadside. Fortunately the garden has a steep banking adjacent where the chip could disappear and the little GM just squeezed through the access. Timber all staying in garden in handleable sizes for the neighbour to take for firewood (rather them than me!).

The wee chipper did us a great service today.

Those jobs are perfect, the neighbour can have all the light cord too.

Nice one @Doug Tait. Like the safety strap

Had to keep the wee beast tethered!

Hi 

looking for a bit of advice from those more knowledgeable than myself regarding a small chipper. Probably only gonna be used 2-3 times a year at my place and similarly at the lads to get rid of max 30mm diameter ( mostly less) branches etc from tidying up a few trees and bushes etc. Just wondering what’s out there to go for and also what’s to avoid.

Cheers

For that kind of use anything will be fine. 15hp best but if a 7hp one comes up for a few hundred secondhand it would do that kind of diameter no bother.
