Default Eliminating fuel pump

On an 82 series tractor, don't they need a fuel pump to run as the tank sits lower than the carb? Would it be fine to replace the fuel pump with a 1-3 psi electric fuel pump or 3-5 psi one? I'm going to be in an engine without one.

If you don't live on a hill side and keep it above 1/4 tank you will be fine. I ran an 1811 without one for a few years.

Well, a good portion of our farm is hills.

What's wrong with a mechanical pump?

Still have't figured out how they work. do they go into the tank and have a line coming out?

They're in-line. They come with directions.

Back to my question: what's wrong with a mechanical pump? No wires, last a long time.....

I run electrics with check valves on my main workers because I trust them more than mechanical ones to not leak into the crankcase. That’s a pretty common thing on KTs and Mags. Can’t speak to mechanical pumps on k-series but I don’t think those are as common on cubs. . You can also make an adapter plate and run a vacuum one.

It's only a common problem after the engine/fuel pump is 25 years old or has a but load of hours. I bought my 1811 in 2002 with about 1300 hours on it. Motor was new at 1175. It now has 2100 hours. I've put ONE fuel pump on it. To me that isn't a bad enough failure rate to justify wiring up an electric pump that may last 10 years if you're really lucky. Failure rate on electric pumps is higher than mechanical.

Fair enough. It's just a peace of mind thing for me. I know that's one thing I (probably) don't have to worry about happening.

I also like that electric pumps can "pre-prime" the carb without cranking the engine.

I think I like the vacuum pump the best of all of them, though, since they are super cheap (and easy) to replace compared to the other two options.

Cub Cadet is a premium line of outdoor power equipment, established in 1961 as part of International Harvester. During the 1960s, IH initiated an entirely new line of lawn and garden equipment aimed at the owners rural homes with large yards and private gardens. There were a wide variety of Cub Cadet branded and after-market attachments available; including mowers, blades, snow blowers, front loaders, plows, carts, etc. Cub Cadet advertising at that time harped on their thorough testing by "boys - acknowledged by many as the world's worst destructive force!". Cub Cadets became known for their dependability and rugged construction.

MTD Products, Inc. of Cleveland, Ohio purchased the Cub Cadet brand from International Harvester in 1981. Cub Cadet was held as a wholly owned subsidiary for many years following this acquisition, which allowed them to operate independently. Recently, MTD has taken a more aggressive role and integrated Cub Cadet into its other lines of power equipment.
