Grease lubrication on Husqvarna riding mower

I have a Husqvarna YTH24k48 riding mower. I've had it about 3 years but it only has 50 hrs on it. It still runs OK but lately it kind of squeaks when turning. I've never greased the wheels or anything so I think that might be the problem. Looking through the manual there is very little info on how to do this. There's one chart that shows to use "general purpose grease" on "spindle zerk", "front wheel bearing zerk", "steering sector gear teth ", and "mandrel zeros". Unfortunately there is no other info that I can find on how to grease these areas. It's simply a chart saying to use grease on those areas but there's no info on how to do it. I have a grease pump gun so I'm good there but I'm just not sure what parts need removed to access the areas I need to get to. I apologize if this is a common sense task but this is my first mower and I don't have anyone locally to ask. I've tried to google it but there's not as much info out there as you would think. Any ideas on how to lubricate this model of mower? Thank you.

Since you have a grease gun, I'll assume you know what a zerk fitting looks like and how to attach you grease gun.

There will be two zerk fittings near each front wheel, these are the wheel bearing zerk and the spindle zerks. You may have to turn the wheels one way or the other to get access. The axle bearing is what allows the wheel to roll, and the spindle is what allows the whee to turn, if that helps you locate them.

The mandrel zerks will be near the top of the spindles that support the blades. You may be able to access them by lowering the deck fully, or you may need to remove access covers. But if you lower the deck fully you should be able to at least see the zerk fittings near the pulleys that turn each blade.

General procedure for using a grease gun is to connect the gun to the fitting and pump the handle. For things like this I usually pump until I see old grease being forced out around the ends of the sleeve being greased. Or if there are rubber boot seals, until I see the boot swell indicating it is filling with grease.

For the steering sector gear, if you follow the steering wheel shaft down through the tractor, near the end you will see a partial gear attached to the end of the steering shaft. There likely won't be a zerk fitting, you just take some grease and smear it on the teeth of the gear. It's a good idea to wipe off dirt and old grease before apply the new grease.

Hope this helps!

Thank you..I found the one that's physically located on the wheel. I was ready to try and grease it..Thought I knew how to use my grease gun (it was new in box) but once I pulled the cotter pin out of the handle to unlock it the spring and all parts came flying out. The manual has no info so I guess I have to order a new gun as I can't get this one back together. It's really frustrating because I guess places just assume you know what to do because there's very little info in the manuals. I'm going to try ordering the Lincoln 1134 gun.. Hopefully I can at least get one use out of it before it falls apart like this one I have sitting here in about 6 pieces..

Unless you have a fabricated deck, I doubt you have grease zerks any place other than MAYBE the front axle bearing.
If you had zerks on the deck spindles, they would be on top of the spindle, with and access hole in the cover for the two outer, but most likely would need a flex hose on the grease gun to access the center one.

Manual

Page 14 of the users manual has a diagram of the locations of the lubricating zerks.

Thanks everyone. I really wish I had paid more attention when Dad was still around. He always stressed how important maintaince was on yard equipment but I guess it went in one ear and out the other. This is the grease gun I ordered, hopefully I can get it loaded up when it arrives Sunday. Stupid question but does the spring stay in the gun?

I've located the zerks for everything but the "steering sector gear teth". I think it may not have one like Paul mentioned. Hopefully I can get the gun working and greasing the zerks will fix my squeaking problem.

Check out this Google link for instructions on how to fill and use a grease gun.

Furd the problem I had was the metal handle was all the way in secured with a cotter pin. The second I removed the cotter pin everything came shooting out like a jack in the box (2 plunger type pieces, a big spring, washer, and the "lock" piece). All the videos I watched they simply pulled back the lever, locked it, and put in the grease cart. Since all my parts exploded out of there it wasn't that easy. That's why I wasn't sure if it the spring was supposed to be in there with the grease cart.

Grease Gun

That's why I wasn't sure if it the spring was supposed to be in there with the grease cart.
The spring keeps the grease pushed to the the front of the gun so the grease will feed into the pumping chamber.

Watch this video: https://www.youtube.com/watch?v=q4FeaYOZGoo and read the directions referenced above.

Thanks wirepuller38, that video did help. I should have heeded the warning in the Lincoln 1134 reviews though. The stock coupler they ship is IMPOSSIBLE to open. I don't have a vice grip so I spent a good half hour trying to open it with no luck. I went to auto zone and bought a basic coupler for use. I finally got the gun loaded up with grease and on my 3rd Zerk, it must have got a bubble in it or something because it stopped working. I unloaded the cart and managed to cut my finger open so I had a bloody mess to deal with. Finally got it working again and was able to grease the 6 zerks. I still need to do the steering sector gear teth but I was too aggravated to mess with it anymore today. The good news is the squeaking appears to have stopped now that I finally completed this maintenance. The bad news is that I must not be cut out for this kind of stuff as it was way more difficult than it should have been. Oh well.. thanks again everyone for your help.

It's not you...grease guns are a tool of Satan. They are messy to load. The cheap ones will never prime and the good ones prime and then airlock after the first fitting is greased. Then they airlock after every other fitting. The couplers slip off the zerks and smear grease on any nearby things that shouldn't be greased, like rubber belts or brake parts. If you have red grease in the gun the job will require green grease. Wherever you store it will get covered in oily slime that oozes from the gun like stink from a skunk till the end of time. If you really want some fun buy one of the locking couplers. They won't slip off the zerk because they can never actually be put on a zerk since they are bigger diameter and won't fit through the tiny access holes that moron designers provide in the equipment.

Honestly, if our society's technical achievement was judged solely by the effectiveness and efficiency of our most common lubrication method, we'd be seen as mere savages banging rocks together in the cold and dark.....

And I'm only sort of kidding
