Mowing Finish mower used for cutting weeds?

Why does this not surprise me? It is great to know the bearing type.

Definitely don't remove seals!

Terry told me to remember to grease up my mower before using it. Unfortunately, I have a brush cutter, which has no bearings to lubricate... It must have been a different customer that he was thinking of...

All the best,

Peter,

Last winter I replaced the spindle bearings in my 60" mower. The bearings installed by PT are 1630-2RS electric motor bearings. I could not see any evidence that any of the grease I pumped into the cavity between the bearings in fact reached the bearings. Most of the bearing seals were in place on my mower. I removed the seals and the grease in the bearing looked to be the bearing manufacturers grease. The center spindle on my deck wash bent. the lower bearing on this spindle was the only bearing that looked to have taken any grease because the seal was damaged. When I called PT for the replacement spindle I questioned them on the need to grease the bearings. I was told that was a good question and I should remove the inner seals. This did not make any sense to me because that would cause the bottom seal to be pushed out and would allow dirt a path to enter the bearing. I have no clue where the tubes of grease that I pumped to those bearings went. (maybe grease heaven) I think this has been discussed in another thread. I have decided to replace the bearings every two years and will not be greasing them.

Note: According to PT they have used two different spindles in the 60" mower. I believe mine is the new design purchased in 2004

Peter..... My brush hog has Grease Zerks... I am worried that you say yours does not. Ours, if nothing else, should be similar in design... Each zerk is located at the base of each spindle (I have 3 spindles).

Look for a grease fitting on the top of the bearing on top of the mower deck. This does need lubrication. Clint Blake had his lock up.

That's where the grease zerk is on my 48" brush cutter...

Peter,

Terry told me to make sure I greased the spindles and I did every 4 hrs of use. When I dissasembled it and saw what was in there my question was why am I greasing this. The older model was a different design spindle and could have required greasing. The question ( is there any reason to grease the spindles PT could not answer). The bearing company said the bearings are greased for life. I continue to grease the rest of the mower.

My 48" brush cutter has one zerk. I think I posted a picture of it here, somewhere.

Here it is installed.

Not sure if this applies, but...

Simplicity mower decks used sealed bearings also, and they have grease zerks on the spindles. The recommendation is to occasionally give them a couple of pumps of grease just to coat the insides of the spindle housing to prevent rust formation from all the dampness that can accumulate inside them. Temperature fluctuations, buildup of "mushy" clippings and such can cause condensation inside the spindle housing. You're not greasing the bearings -- you're keeping the housing and the arbor shaft from rusting...

Don't know if that's the logic behind this Tazewell recommendation or not...

The 2007 72" brush cutter is a direct drive with a hydraulic motor. It has a single shaft, two blades, no belts. And, yes Virginia, you do want to engage the PTO with the engine idling.

There are zerks on the wheels, and the attachment plate, but not on the mower.

I didn't mean to concern those of you who have other designs.

All the best,

Peter

Our 48" is a direct drive, too.
