What Options Does Your Cub Cadet Need?
Your Cub will need a rear 3 point to raise and lower your moldboard plow, tiller and disc harrow. If you are using a sleeve hitch plow you will need a sleeve hitch adapter.

The black part is the sleeve hitch adapter.
The white part is a stablizer plate.
The parts that the sleeve hitch adapter is connected to is the 3 point hitch.
The plow weighs around 70 pounds. You will need some type of helper lift to help raise the plow. There are 3 different types: manual lift with a helper spring, hydraulic lift, and electric lift. Hydraulic lift was standard or an option on most wide frame or newer hydrostatic trans Cubs. The Orginal and all narrow frame Cubs had an add on hydraulic system you could install on your Cub. Here is what narrow frame hydraulic system looks like:
Tires
Your Cub will need ag tires or chains on turf tires. Ag tires work the best in your garden. There are several different tread designs on the market. Best thing to do is ask someone in your area who is using that brand. Different soil conditions may dictate which tire works best for you. You can buy tires through the internet, different tractor shows-plow days, and different tractor sites. Most tractor sites had several topics on ag tires.
Additional Weight
Extra weight can be a big help in the traction department. Most will add weight in the rear tire area. There is 2 types of weights that are commonly used: wheel weights and fluid inside the tires. What style of weight you use is your choice...Some use both.
Do I need front end weight?
The front end is light on my Cub when I plow or till. I have no personal experience with a disk harrow.
