Removing riding mower blades

Removing the blades is not that easy on my rider.
I am lucky enough to have a 500 lb. chain hoist and a big maple tree in the yard, and can lift the front end enough to get under the deck. But i think those blade bolts tighten up when u mow for some reason.
Have tried several things over the years to hold the blades from turning when breaking those bass todds loose. Blocks of wood, vise grips, and so on, but still end up sometimes with cuts and abrsions. Becuase i can't get the ol impact wrench out to where the tree is, here's what's worked pretty good lately. Come in from the grass discharge opening with a 3" 4 ft. pc. of PVC pipe, i think sch 40, and slip it over the blade on that side. Take the socket on about a 14-18" breakover, turn till things bind and stop, then tap the breakover handle with a hammer to break loose the bolt or nut. Go to the other side and do the same. That's why the pipe is 4 ft. long.
Always wear gloves when putting the sharp blades back on, if u slip off the bolt, big cuts can accure.

good luck out there

How do i change the chain on my model 108526-01

The proper sequence to installing the chain should be to first ensure the brake is in the 'unlocked' position then loosen the chain adjustment screw, slip the chain over the back of the sprocket, align the chain with the bar, slip the bar onto the bar mounting studs ensuring the adjustment pin slips into the appropriate hole in the bar. Then slip the outer chain cover over the bar studs, elevate the front end of the bar and tighten the bar mounting nuts to 'snug'. Adjust the chain tension to the desired setting ensuring the front of the guide bar remains elevated, then tighten the nuts to secure the bar.

Remember to unlock the brake BEFORE removing the bar and chain because it is so much easier to unlock it mounted on the saw if yours is the design that comes off with the cover.

Keeping the front of the bar elevated during assembly and adjustment of the chain will keep the chain tension correct for a much longer period.

My poulan 18 inch chain saws blade turns but only cuts in about an inch and won't go any farther. It's two days old and worked fine cutting the first 2 trees down.

It sounds like the chain does want sharpening, it depends on what you are cutting ( type of timber, dirty timber,burnt timber etc ) as to how long before it needs sharpening, if the chain comes into contact with the ground below the tree it will lose its edge instantly.

I am going through my husbands tools. We have a Ryobi Saw-all and I notice it has different blades. I can not find the manual. I simply want to change the blade for cutting iron that is currently inserted...

To change blades, a hex-wrench is required and you simply tighten or loosen the allen screw that holds the blade, but unfortunately the saw's design is a bit flawed. It takes a bit of "feeling around" to locate the proper position for the blade changing wrench because the fitting is not visible through the rubberized boot. You can certainly trim and prune trees with the saw, but make sure that the branch is at least 10% thinner than the length of the blade. I do not know your Manzanita tree, but if the wood is wet it should present no problem. Any power saw is extremely dangerous if used at an elevated height like on a ladder. If the ladder slips, there seems to be an almost unnatural tendency to grab for the saw and very often the moving blade. Take the utmost care at all times with power tools. (I have a friend who point blank refuses to use a chain saw unless both his feet are firmly planted on the ground, and he is over 6 foot).

Chain slips

Your problem statement seems to be chopped off, but apparently, when you go to cut something, the chain just stops turning. Assuming that is so, remove the bar and chain, then wash out the interior of the clutch mechanism with spray carburetor cleaner. Let dry and re-assemble the bar and chain. Make sure the chain is being properly oiled by running the saw at speed with bar tip near some cardboard--it should leave thin line of oil after several moments. Make sure the chain teeth cut toward you on the bottom run of chain. Hope this helps!

The chainsaw boges down on me a lot with bigger trees there any way to maybe put on another clutch or by-pass it

I would definitely NOT bypass the clutch. Bad things happen if you do that.... such as missing body parts if it binds or kicks back. Not to mention the sprocket on the engine is actually built into the clutch bell/drum and you'd have to mickey mouse rig it to work. If the saw is bogging down and the chain is not slipping, then it's not your clutch. It's either an under powered saw for what you are using it for, you are putting too much pressure on the bar and not letting the chain do it's job "at it's pace", or the chain is dull. Easiest thing to do is replace the chain with a new one and see if the performance improves. I found that often replacing a bar and chain with one a few inches longer vastly improves the cutting and reduces the bogging quite a bit.

Chain stops when contact is made with tree

I'm assuming that the engine continues to run, but the chain stops moving. Remove the bar and chain. If the clutch internals are full of bar oil and other debris, try washing out the clutch with spray carburetor cleaner from an auto parts store. After it dries, inspect the shoe faces and inner drum area for excessive burning or scoring. Apply a small amount of oil to the clutch hub bearing, then reassemble the bar and chain. If the chain now cuts correctly, you are home free. If it doesn't, then the clutch will need replacement. Hope this helps!

Chain Slipping

Your chain would have to be incredibly loose to slip the sprocket. Enough that it would come off the bar before jumping the teeth on the rear sprocket. Highly unlikely.
