While many mower repairs beyond standard maintenance require authorized service personnel, you may be able to handle some minor fixes and troubleshooting. General information for some common gas-powered mower fixes is below, but always follow the manufacturer's instructions. Disconnect the spark plug before working on a mower.

No Gas or Wrong Gas in Your Push Mower Fuel Tank

Begin with the most obvious problem: fuel. If you don’t have gas in your push mower, your gas-powered mower will not work. Most push mowers today use a 4-cycle engine that require an unleaded gasoline with an octane rating of 87 or greater and an ethanol level of 10 percent or less.

Bad or Old Fuel in Your Push Mower

Gasoline begins to break down and lose its effectiveness after 30 days.

Step 1: The Return From the Hardware Store

I went to Home Depot, which is just a big box store, only because they were the closest to my house. I wanted to keep the cost of this repair low and planned on scrounging my junk pile for some of the parts, but i couldn't find any casters or bolts in the junk pile.

Step 2: The Needed Tools

The tools I used are as follows: Cordless drill- what a bust both of my batteries were dead 1/8th inch twist bit spring loaded center punch- i didn't feel like looking for a hammer a few unistep bits- one was to long to fit in the brackets i made and the other had to big of steps.

Step 3: Make Some Brackets

To start this repair i had to make a set of brackets to fit inside of a slot already on the mower and my tubing was a little bit to large to fit (1/8th off in wood =no sweat, 1/8th off in metal= oh dear). I figured i could just cut off slices of my tubing narrow enough to fit into the 3/4 inch slot.

Step 4: Drill and Widen the Holes

I used my eyeball gauge to center punch the location of my hole in the brackets. It didnt have to be exact only close. Center punching is worth the few extra seconds it takes to do it. I have had drill bits skip around, break, marr the work piece and bloody my hands all because i didnt center punch first.

Step 5: Attach the Brackets to Both Sides

All the holes were drilled and it was time to assemble the brackets. (I made three sets of holes on the brackets to correspond with the three sets of holes on the slot. This allowed me to adjust the height of the reel mowers blades pretty well. The washer that went into the bracket had to be ground down some for clearance.

Step 6: Make and Weld on the Cross Piece

Fine measurements not needed. I stuck a piece of tubing between the brackets and scribbed a line. This would get me close enough with out needing to located my tape measure. After i cut the tubing it was a friction fit, perfect for welding. Two welds will keep it secure, I mean come on its on a real mower not holding in elephants.

Step 7: Affixing the Casters

The casters were a little difficult to affix to the cross piece tubing with out them slipping off, until i took the actual wheels off of the casters themselves and then just clamped the brackets for the casters to my tubing. This worked great.
