How to Glue a Lawnmower Seat back on, step by step

No matter how cautious a person is with his lawnmower, it is always possible that the seat from your riding lawnmower is damaged. The most common problems include the vinyl covering coming separating from the foam cushion. This exposes the foam to the environment, it will damage further, and water gets absorbed. If you do not fix it, the foam gets hardened in the sun and finally crumbles away bit by bit. Despite the loss of comfort, it is also an unpleasant view.

To fix it, it is necessary to remove the seat and glue the sear back on it. This article will discuss how to glue the seat back on the lawnmower platform after necessary treatments.

Fix your lawnmower seat with glue in 7 easy steps:

Gluing the seat back on in a riding lawnmower is not a difficult task. Follow the steps, and you will have a great-looking seat in no time.

● Step 1: Inspect the lawnmower

Before you start removing the lawnmower’s seat and start using your glue, you should keep in mind that there are numerous types of riding lawnmowers. And their seats may come in various sizes and shapes. Some have seat pans that are made from fiberglass, while others may have metallic ones. It helps if you know the specifications of your machine before starting. The following step may be modified depending upon your device’s specification and type, although the general guidelines are pretty much the same.

In the case of a one-piece lawnmower, seats may be impossible to fix. In that case, it is recommended to look for a replacement seat assembly. Check with your dealer or try to find one on Ebay.   

● Step 2: Collect the needed equipment

Once you are getting ready to fix the seat back on your lawnmower, it is good first to check if you have all the needed equipment. You need a wrench to remove the seat. The wrench size may depend on your lawnmower’s seat. If your seat cover is made from vinyl, you need vinyl glue. If your seat is made from another type of material, like leather or some type of plastic, make sure that your glue can work with this kind of material. Some glue can not work with certain types of plastic and can even dissolve it partly.

So you need the correct glue, a wrench set, a flathead screwdriver, a sharp knife or cutter, and strongly adhesive duct tape.

Moreover, depending upon the foam type and damage of your lawnmower’s seat, it is necessary to have replacement foam, Foam Lok, or a similar adhesive and a sharp foam cutter with you all the time during this process. This can be used to repair part of the foam.

● Step 3: Remove the Seat

After analyzing your lawnmower model and gathering the necessary supplies, the next step is to remove the seat. This step varies from a lawnmower to lawnmower but should be easy to do.

The general method is to push the seat up and forward in the steering wheel’s direction. The seat is held to the seat mount with the help of two to four nuts. Once these nuts are removed, the seat comes off easily.

To make sure that you do not lose the nuts, screw them back onto the threads from which they just came off.

● Step 4: Remove the Vinyl Cover

It is necessary to remove the entire vinyl cover even if it is unplugged on a tiny spot. The reason for removing the whole surface is that no matter how minor the spot is, it will continue to come unglued.

Once the seat has been removed, invert it on the workbench. Depending upon the seat pan type (that is, fiberglass or metal), there might be staples or rivets, respectively. In both of these scenarios, the glue will be present. Now with the help of a screwdriver, pop the pins or pry the staples until you have set the seat free. With the use of your pocket knife, precisely cut the vinyl free from each rivet to avoid vinyl tearing from around them.

To deal with the factory set glue, carefully pry the vinyl up one inch at a time. Work your way around the entire seat carefully such that you get the vinyl removed without massive shreds. If this goes really difficult, you could carefully try to use some glue remover with a small brush. In case of no glue, you could lift the vinyl off the seat.

● Step 5: Treat the foam cushion

Once the vinyl is removed, it’s time to analyze the cushion. The cushion can have missing chunks, or bad spots. Fortunately, both problems are straightforward to solve.

Firstly, turn the seat over on the workbench. To cover the missing chunks, cut replacements from the substitute foam. These could be used to fill the damaged spots. If you can not find suitable replacement foam, you can try to use some from sources like an old patio or sofa cushion.

Spray some Foam Lok into the damaged regions and start pressings the replacement part inside. Once the pieces are into the hole, press them inside and wait for 15-20 seconds to help it settle with the help of your palm.

● Step 6: Glue the vinyl back on

Take the vinyl cover and lay it on your workbench by turning it inside out. Align the treated seat over the vinyl such that the foam faces down on the resting vinyl. Once both of them are in perfect synchronization, slowly fold the vinyl up and over the seat’s bottom half. Make sure that it looks even, and you don’t bump it.

After that, take the vinyl glue and squeeze a considerable amount on the seat pan’s bottom and from front to back face. Ensure that the vinyl completely covers the bead of glue when you are folding it from the backside.

Squeeze the glue on the other side of the seat, from front to back. Fold and press one side of the vinyl firmly on the bond. Workaround the seat carefully. Repeat this process for the other sides and make sure that it correctly holds the right way.

You must carefully pull the cover straight, so it looks evenly spread around the seat. If it is uneven, pull the vinyl either way to balance the seat cover. Once the shape is ok, press the end of a duct tape piece firmly on the vinyl’s edge.

While you are pressing it down, stretch the other side of vinyl towards the seat pan’s central position and press it with duct tape. This will stretch the entire seat cover back on.

The sides are now places. Repeat this gluing process for the front and the back too. Once you are done with it, let the newly repaired seat rest overnight or according to the instructions of the glue you used.

● Step 7: Replace the Seat

Finally, with the help of rivets and nuts, attach the seat back on the lawnmower, just like you initially removed it. Make sure that the nuts and screws were firmly tightened.

1. What’s the best glue to use?

The market has various brands all around. When searching for a good glue, make sure that you do an online search. Make sure it can be used for the material you try to glue. Check the credibility of the product by checking some of the reviews from people who used it.

Loctite Vinyl glue is one of the most practiced and credible bonds all around the market, with good ratings and reviews. Flex Glue is another good product manufacture by the company Flex Seal. The best glue is the one that has such a drying time that you could not only position the vinyl and the duct tape without the glue getting dried out but also not have to wait for an eternity for it to dry down.  

2. What if the seat cushion is flat?

Foam could lose its flexible attributes over time. In that case, measure the foam and look for a substitute online or on Amazon or eBay. Even if you don’t find the exact shape, you can cut it with a bread knife to the correct shape.

3. What if the seat cover is cracked?

UV rays from the sun can make the vinyl cover brittle and cause it to crack. If it is just a small part, you could first try to fix it with some colored duct tape. There is a wide variety of colored duct tape, and if you can find one that matches the original color, you can hardly notice any difference between the original vinyl and the tape. If the damage is wider spread, there is no other option than looking for a new cover or a replacement chair.

Final Remarks:

Gluing the lawnmower seat back on looks like a complicated task. But if you follow the step mentioned earlier, along with the instruction from the reference videos, you can do it without any problems. Ensure that you have the correct glue and replacement material if needed.
