P337 Full Robertson/STOL & De-Ice

[cbxmike]

So, I just purchased my 2nd Skymaster. Yes, I’m a glutton for punishment and weird planes. This one is a 1977 P with full De-ice and a partial Robertson STOL (Cuffs only), with three bladed MT props, and the gear door mod. There are VG’s on the fuselage behind the mains in two areas as well. We are moving to a grass strip that’s not the greatest (yet) and my question is rear prop damage? These Skymasters seem to have an oddly decent short field performance for a light twin, but will my rear prop take a beating over time? Mostly grass with some dirt and light shale type rocks in isolated spots. My last Skymaster took a small bolt through the rear prop after another mechanic did some work and before I could do a thorough inspection. It damaged a rear blade pretty good, so I’m a bit worried about heavy use on grass strips. Any insight, guidence or differing techniques would be great. Mike.
