How to Identify and Fix Common Gardening Problems ?
We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :
Always cut on the compression side first! The area on the outside of the bend will pull apart when cut. This is the tension side. If you decide to cut this side only, the tree will split apart before the cut can be completed.
A bypass lever is located on the back of the frame, pull out on the lever to move the mower and push it back in before mowing.
There are three main reasons for a chain to come off: Incorrect bar and/or chain for the saw; check to be sure that you are using the proper chain pitch, gauge and number of drive links to match the guide bar. Chain not properly tensioned; It is normal for a new chain to stretch and require frequent adjustment.
There is a tension screw located near the base of the bar on the chainsaw. To tighten the chain, turn it clockwise, and to loosen turn it counterclockwise. Don`t over-tighten the chain as this could cause it to break.
The Official Textbook of Pedal Placement™ states that, apart from vintage fuzz and wah, compression should always be first in the chain.
Generally speaking, the chain should be a little loose on the chain saw guide bar, but not loose enough that the drive links come out of the bar nose. The bar links should feel like they are raising up, but not actually come out of the guide bar.
A chain will run properly if wear elongation does not exceed 3 %, depending on the application, and provided that it is constantly re-tensioned. If it is not, the slack thread will sag further and further, resulting in uneven running, higher wear and increased noise.
ROPS, or rollover protection structure, are cabs, frames or bars that protect operators in the event of a rollover. According to Consumer Reports magazine, in 2007 there were 61 deaths and 15,000 reported injuries on zero-turn mowers.
These control rods are adjustable. By rotating the threaded linkage connector ferrules, the length and the resulting range of movement at the regulator valve can be altered.
Force, which in this case is chain tension (since that is how the pedal force is transferred to the rear wheel), is torque divided by radius (i.e., force = torque/radius).
The rule of the thumb says that the exact tightness of a chain will only let you move for about half an inch. Now, if the chain is too loose, then you need to tighten it. If you cannot even move the chain, then it is too tight, and it needs to be loosened.

After a few months in storage, my saw will start, but the chain seems stuck – I can[‘t move it with my fingers, and when I gas up the engine, the chain doesn’t move & the engine stalls. There’s no rust, plenty of oil – everything is clean.
ANSWER : Release the chain tension adjuster and push the bar inward to make sure it moves. This is an auto-set tension adjustment and should set itself so that the chain can be be moved by hand. The chain oil on the bar may have gelled enough to prevent chain movement. A spray of WD-40 around the chain perrimeter would probably loosen the chain as well. Hope this helps!

I am having problems with the chain coming off the guide rail of a Husqvarna 345. A new rail and chain was put on the saw recently. When the chain came off last time I noticed a lot of wear on the teeth that sit in the guide rail – in some cases the teeth were almost worn away altogether. The chain is getting oil. What could be causing this – I am wondering if the chain should be tighter.
ANSWER : It is possible that the clutch sprocket teeth are badly worn causing extra wear on the drive teeth of the chain. Remove the bar and chain to check the sprocket–you can determine the wear by comparing the area where the chain runs to the edges of the sprocket that are relatively unworn. If the sprocket requires replacement, the chain should be replaced as well. The chain normally should be loose enough that the chain can be moved by hand, but it should not droop from the lower bar edge. Check the chain oiling by running the bar tip at speed near some cardboard–it should throw off a thin line of oil after a moment or two. There should be an oil volume adjustment screw located on the under side of the case near the chain return area–turn CCW to increase flow. Hope this helps!

Husqvarna 350 chain saw not getting fuel – Husqvarna Chain Saw 20" Bar
ANSWER : Hi you will need to put on its side and fish out the fuel line, if it is like strechey rubber when you hold it you will need to replace the fuel line and filter. If this doesnt work you might have to rekit the carb or replace it. replacing it will be better since you will be paying about as much if a shop does the rekit and it is only about a 50-50 chance the carb got clean. hope this helps
