So I have the usual tools/wrenches to work on car/motorcycle and stuff around the house but realizing they are generally not large enough to do basic work on my new L3902. Does anyone have a good idea of what sizes/tools I should get or a suitable set from Harbor freight to cover most of what I would need?

thanks
Ben

If your L3902 has the turnbuckle style lift arm stabilizers get a 24mm open end wrench. A larger/longer adjustable wrench can be hard to get in and on the turnbuckle jam nut depending on what tires your running. I have R4's on my L2501 with no spacers and it gets really tight on space.

I know the top link adjustment jam nut is larger than 24mm but I use my adjustable wrench for that one. It is easy to access.

The category 1 lift arm pins on one of my implements uses a 1 3/8 inch imperial nut to secure to the implement. I had to buy a 1 3/8" deep well six point socket 1/2 inch drive for that one. The nut is recessed in the frame work and not accessible with a box end wrench etc.


Other than that a normal set of 3/8 and 1/2 metric sockets and set of combination wrenches should cover 90% of fasteners for normal adjustments, maintenance etc.

You will need to get sockets and wrenches above the normal car sets that usually stop around 20 mm or so. Get up around 20 up to 28 mm or so and you should be good for almost everything. You might want to just get impact sockets but be sure you get 6 point sockets for the larger sizes so you don’t round off the corners.

Bit OT. Discovered as expected the sets of metric and imperial size sockets and wrenches were on the too small size. Decades ago there was a Sears store a short walk from work. After work walked over on a regular basis to Sears. They had a section of returned and odds and ends tools. Slowly acquired the additional wrenches and sockets. Also, larger beam style Craftsman torque wrench. Unsure if the Sears Robogrip pliers were real or just Sears branded. Don't remember if purchased at the Sears store. Handy tool that sits in the tractor tool box. Bit like channel lock pliers.

Mix of brands sitting in the tool cabinet. Real Craftsman, SK, and Tekton. One amazon generic purchase. Finally bought a real Milwaukee impact wrench. Needed some deep socket impact sockets. I sure hope the amazon purchase don't break.

The Tekton tools out of Grand Rapids, MI are manufactured either in the USA or Taiwan. Seem to be decent quality. Free shipping for orders over $25.
