Hello Everyone.
I am new to this site and I may be posting this in the wrong spot,feel free to advise me.
I have a older but well maintained Cub Cadet Enforcer,2008 I think.The engine is in perfect running order,compression is at factory level,High running RPM,s may be a tad bit low but now by much.Belsts are new,unit very well greased,blades keep sharp.
Here is my problem. I cannot cut longer grass with this unit unless I crawl with it,I have a cub cadet rider,21 hp I think,it will fly past it.When in long grass the RPM on unit drops and grass is not cut very even then.Keep in mind I have ear protection on and I am not 100 percent sure rpms are dropping a large amount.Blades are on tight and do not slip. I was wondering if it may be my electronic blade clutch,do they slip with age? Thanks for any advise or direction I should go. Matt
