Can you put 2 blades on a lawn mower?

Last Updated: 1st February, 2020

Yes! Very easy if your blade is secured with a 5/8 bolt that goes thru the spindle and secured with a nut on top like my 52" commerical mower. I installed 2 hi-lift blades on my 52" walk behind and also on my Woods RM 59-3 rear mount PTO mower. The PTO mower uses a 5/8 screw rather than a bolt but works fine.

Consequently, why is it a good idea to have two blades for your mower?

2) Sharp blades actually cause you to use less gas. A sharp blade provides a clean cut, which helps the grass to heal faster and promotes photosynthesis. Experts say it's a good idea to have your lawn mower blade sharpened two to three times a season to maintain peak efficiency.

Similarly, how tight should lawn mower blades be? To tighten the bolt or nut use a torque wrench and tighten it to proper torque specification. Walk behind mower blades should be installed between 38 and 50 foot pounds of torque. Riding mower blades should be installed between 70 and 90 foot pounds of torque.

Thereof, how many blades does a lawn mower have?

Reel mowers are available in three different styles: Four blades. Five blades. Seven blades.

Are lawn mower blades universal?

In short, the answer is yes. However, you must ensure that the centre hole and length of the blade is the same as the one you are replacing.

Why does my mower leave a row of grass between two blades?

A strip of uncut grass left in the middle of mowing rows could signal that your lawnmower's blades are unbalanced or that one or both of them was installed the wrong way. Ensure that your mower's blades are on correctly, that both are secured tightly to the mower deck and that both are balanced.

What causes my mower to leave a strip of grass?

Streaking is when thin strips of uncut grass are left behind the mower. Streaking is usually caused by operator error or poor blade maintenance. Streaking can occur if the engine speed is too low. Believe it or not you are doing more harm to your engine by running it slower than full throttle when you are mowing.

How do you cut an uneven lawn?

Method 1: Leveling out a Mildly Uneven Lawn by Topdressing
  1. In a wheelbarrow or similar container, mix up a batch of topsoil, sand, and compost—basically, a soil medium that can support turfgrass growth.
  2. Apply 1/2 inch of this soil mixture on top of the low areas.
  3. Rake the topdressing to spread it out evenly.

Is mulching better than side discharge?

Some contractors feel that bagging systems provide a higher quality of cut than either side-discharge or mulching systems and are able to handle even the lengthiest of grass blades. When mulching, disposal is instantaneous, as the shreds of grass are thrown back onto the turf as soon as they're mowed.

Should mower blades overlap?

This is where no grass is cut, and the aim of the mowing process is ensuring you overlap every row so that the cut is as even as possible. As a general rule, estimate between 7 to 10 centimeters, which is the best distance for a correct overlap – depending on the current length of the grass you are cutting.

What's the difference between mulching and regular blades?

The primary difference between a mulching blade and a regular blade is shape. These design differences give a mulching blade the ability to keep grass clippings circulating under the mower deck, allowing the blade to cut the clippings repeatedly into smaller and smaller pieces.

Can you put a lawn mower blade on backwards?

Most replacement blades are stamped to indicate which side points down. One way to ensure that your lawn mower cuts the grass properly is to inspect and replace the mower blade. Mower blades have a cutting edge at each end. It is common to install a blade upside down.

How do I loosen a lawn mower blade?

To remove the blade, you must turn the blade's retaining bolt to the left, or counterclockwise. Before undoing the blade, tip the mower on its side with the engine air cleaner facing up and block the blade with a piece of wood so it can't turn.

Can a lawn mower blade fly off?

Some manufacturers recommend using a torque wrench for this task, since overtightening a bolt could cause it to crack, while undertightening it could allow the lawn mower blade to fly off while the mower is running.

How many times can you sharpen a lawn mower blade?

Your lawn mower blade is dull. Sharpen the blade twice each season to help maintain a green, healthy lawn. A sharp blade not only cuts blades clean so grass plants recover quickly, it helps reduce your lawn mowing time.

How often should lawn mower blades be replaced?

For most rotary (motorized) mowers, I recommend sharpening the blades every 20-25 hours. For a lawn that takes about 45 minutes to mow, that means you should sharpen your mower blades every 26-33 mowing sessions.

Which way do you tilt a lawnmower?

If your lawnmower is four stroke (which it is), tip the mower so that the spark plug is pointing skyward, never tip it on its side with the spark plug to the ground. I cannot work out on which side to tip my lawnmower.

Which direction do mower blades go on?

Most lawn mower blades rotate in a clockwise direction (counter-clockwise when viewed from below), and as such have the cutting edge on the right side. If you are unsure of how your mower rotates, check the position of the discharge chute; if it is on the right side angled back, the blade turns clockwise.

Do I really need a torque wrench for lawn mower blade?

The owners manual recommends torquing the blade bolt to 35-40 ft. lbs. If you have a torque wrench it is good to use it. If a torque wrench is not available, use a wrench around 12-15 inches long and tighten the bolt as tight as you can get it.

Should lawn mower blades be loose?

The blades should not be really loose, they should be firm to move amd not that tight that you cannot move them. The reason for the blades being able to move is because if they hit an object they will swing back (so they don't break) and then return to the correct position in operation.

Is a lawn mower blade reverse thread?

Most lawnmower blade nuts are reverse-threaded in order to secure the blade on the drive shaft of the engine. This ensures that the blade's rotation does not loosen the nut. However, not all blades use a reverse-threaded nut to secure them to the engine's drive shaft.
