Best Post Hole Digger for Tractor Buying Guide

There are some post hole diggers out there that are worth every penny, and some are not. Here are some of the important things to watch out for:

Ease of connection

Since the post hole digger is to be connected to a tractor, an important factor to be considered is how easy it is to get it efficiently connected to the tractor. A lot of tractors have 6 spline PTO auger and you will need a hole digger that is compatible with that too.

Get a digger that works well with both the small subcompact tractors and also the larger ones. Make sure the joints and attaching components are intact and made of resilient material, that is because you might have to attach and detach them very often, all depending on your volume of work and diversity.

Versatility

You need to get a post hole digger that is not limited in terms of diversity. Different lands have different topographies and textures, therefore, requirements to work on them may differ.

Some post hole diggers have self-sharpening blades that are capable of digging through various soils and landscapes, including rocks and tough soils. Such self-sharpening blades are made of steel and can maintain sharpness for the digging edge, even over long time usage.

Heavy duty steel is a go-to trusted material for versatile blades. Since most hole digger has this, it is quite appropriate for it to have a pivot lubricator too. The use of grease with the tools pivot and blade will ensure that destructive friction is avoided while working with different types of soil.

If you have a 2 gear shaft or you have a 2 gear shaft auger, a lot of versatile post hole diggers will work with both.

Presence of protective shield

It is not all post hole digger that come with a protective shield and that is a factor that should not be understated. Shooting stones and flying debris can be really dangerous, especially when the tool is working at high speed or working on a tough soil.

Quality shields should be provided along with the PTO driveline. This feature should not only keep you safe, it also gives you less worries and more confident presence. You achieve more when you don’t need to look out for yourself.

Replaceable edges

Firstly, it is good to have a strong and effective blade, especially a self-sharpening one like I mentioned earlier. It is not all. With experience, you will later realize that it is even a greater feature for the tool to have removable edges. One shoe doesn’t actually fit all in the business of post digging.

The simple way the soils and topography are different for various places, that is the same way various edges are perfect for different jobs. Even if you have a self-sufficient blade edge, it doesn’t hurt to have different options.

These options serve greatly for different scenarios; they also ensure longer life span of edges. Also, make sure the material for the replaceable edges are resistant to corrosion.

Flow rate of work

The operation of the post hole digger is heavily depending on rotational components which can technically translate to the rate of work. Angular velocities and rotational speed is an actual specification to be stated.

An experience operator knows the parameters required for each job but there is an acceptable range of timed revolutions. With a minimum speed of about 10 rpm and a maximum speed of about 125 rpm, your post digger is ready to handle most jobs.

Working dynamics

It is not all post hole diggers that can work in challenging situations. Having a post hole digger that can work uphill or even work in sloppy area is definitely a deal.

To know the extent at which the post hole digger will perform, it will require a solid level of experience or intense research. Trust me, the consultation and researches will definitely be worth it.

Weight

Weight is definitely an important factor. The hole digger should not be too heavy, massive weight reduces the ease of mobility and connection. There are some diggers that weigh over 200 pounds, you don’t usually want all that weight.

The only reason you should buy a heavy post hole digger is if it has other advantages making up for that downside.

Warranty

In general, the post hole digger is not really a very cheap tool. It is definitely a wise thing to look out for an option that comes with some warranty. A warranty lasting between one to three years is great. Within the time frame, you will enjoy some benefits from the manufacturer or distributor.

Services and repairs are free under the warranty grace period in post hole diggers including gas powered auger. You won’t be in headache when the digging edge is getting blunt or the rotating speed reduces, all that will be covered by the distributor or manufacturer, among other services to maintain tool quality.

Final Thought

Each post hole diggers that made it to this list are made from premium quality steel to withstand all the hustle and bustle that comes with digging through dirt.

We have reviewed them with their respective features, as well as the type of tractors they fit best with. They all have safety protectors around the tractor PTO shaft to ensure you are protected from any accidents that may occur.

When choosing the right post hole digger for your tractor, ensure it matches your tractor’s power and category. All post hole diggers on our list are compatible with 6″ 9″ and 12″ auger bits. So, anyone you choose, you don’t have to worry about it not matching these sizes auger bits. Although, some come with all three diameter auger bits mentioned, some with one (6″), while some with none.

In conclusion, post hole diggers are PTO-driven, which make them dangerous. There’re safety guards for safe operation, but the operator needs to be safety conscious. Ensure you don’t wear any loose clothing while digging holes with this equipment. Otherwise, it may pull it in as it rotates, which will be hazardous to you.
