I have been using XHT hi lift blades for a couple weeks now,they are the best blades for this machine in my area hands down!!
The stock blades would not even pick up small sticks,,these XHT blades pick up twigs,sticks,pine cones,chops them up and spits them out,,alot better cut quality also...no more scragglers like before and the blades are holding an edge for over 10 hours now and still cutting great!!
I have not noticed a drop in fuel consumption or the engine working any harder than normal either...even though Im sure it is a little
The only con I can think of is you will throw more dust and dirt around when its dry with these blades,Id say 35-40% more suction easy!!
These blades are hard as a rock,not like alot of those other brands made who knows where...these are made here in USA.
Here is a link to the same ones I got,,I will be buying more of these blades for sure,,best blade yet for the RSD 54 IMO.
