Heavy duty brush cutter
I made a heavy duty pull behind brush cutter several years ago to go behind a atv, it worked great but had some design flaws that caused it to be parked for quite some time. Now that I have my cub cadet I am plotting on fixing it to be used behind the cub.
One of the issues was the turning radius, unless you were cutting a field it was impossible to maneuver. Behind the ATV it ended up being over 14' long. To solve this issue behind the cub I am planning to solid mount it to the cub and mound swivel wheels on the back. I will control the height with an electric actuator and linkage similar to what is used on large bat wing mowers. Basically it will pivot up and down on the back of the cub and the wheels. Another issue I have to address is the controls, I had an issue coming up with a throttle cable long enough to reach the seat of the ATV, with it mounting so much closer to the cub I believe I won't have so much trouble with this. Also I don't have any type of clutch and im not sure how I am going to address this issue, an electric clutch was discussed but I may leave it unclutched for now. I also need to change out the cog belt for just standard vee belts as the cog turned out to be a little too positive and ended up eating a belt. Vee belts will be cheaper and more readily available in town it I were to end up shredding one. Without further ado here are some pictures I took 5+ years ago right after I got it running, it was capable of taking down 1" saplings with ease and would chew up head high briers and brambles. The blades are 3/8 AR 500 and are break away just like the real deal.

Amazing idea!!! the swivel wheels will help big time - curious? i noticed your just using a flat piece of round steel to hold the blades - have u had any issues with vibration - i was just thinking maybe some type of counter weight to help the blades cut smoother an less tension on the belt? An your throttle problem - would a magnetic solenoid connected to the throttle of the engine help - that way you can run a toggle switch on your dash to go from idle to what ever rpm you desire.I would really like to see more if you do anything different - that idea has been on my mind for years!!!

ive been toying around with the same idea...only using a Timed mower deck from an original with a hitch and wheels to mount to the cub cadet. my 122 has a rear PTO so ive also been toying with the idea to make it PTO driven. if i did my math right it should spin the right way the way i have it configured. your brush hog looks like its very heavy built. good job on it.

http://www.deltrol-controls.com/prod...x2700/53792-81 Excellent idea this will only give me idle and WOT but that is all that's really necessary anyhow. Only runs about 21 bucks from Mcmaster Carr. I may try and work towards getting this mounted behind the cub this weekend but it all depends on how I am feeling.

Thats the same company i bought some from! lol! i just want to mention = watch out for the amount of force it takes too pull your throttle = i connected it to a 31 hp briggs an found out the hard way = the governor pulled alot harder than i thought. I was also thinking if you have a scrapyard around ya that deals with heavy machinery like a man-lift = they have the heavy duty solenoids on them with the bracket so you can adjust it??

Pulled it out of the weeds this afternoon and got a set of heavy duty swivel casters mounted to the rear in place of the fixed wheels. Didn't take any pictures but I did run into a big roadblock. I am missing critical parts of the motor. Im going to make a post in the wanted add but unless I can come up with parts cheap or free I will be forced to change out motors. I have a good complete 18hp OHV I may have to go to.

I know that when they sell brush hogs for big tractors, they encourage people to hang dog chains on the front for the pull-behind models. This keeps the blades from throwing things into the operator, tires, nice paint jobs, etc. I couldn't imagine something flying out and hitting you, but it may ricochet and hit you or a bystander. Safety first!

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.
