Bob!
Here,s a tip on your Cub Cadet .
If it has a Kohler engine , you MUST run 10w-30w oil;Do not run 30w.. The V n12 Kohler has hyd. lifters
(they look exactly like a chevy.) .If you run straight weight you very likely will live to regret it and soon!
If it has the kawasaki, run the Kaw , factory oil; It will double your engine warranty.
The biggest problem with zero turn units is people tend to find out how fast they can mow with them
and do just that.The slower you go, the better you mow. They cut a good looking yard.
Will quick take offs and blinding turns hurt them?No more than it will your car.
Hyd. replacement units ain,t cheap and driven properly , last a long , long time.(Hydro Gear I beleive.
Any questions just email me and I will try to answer them.
