The Fandrich Aerial Shear:
The Fandrich Aerial Shear is:
You've probably read that in true fir, the Fandrich aerial rake collected cones 4 times faster than the aerial clipping method using an operator leaning out of a helicopter.
Now use a Fandrich Aerial Shear and combine the advantages of aerial clipping with aerial raking:
| IF | you haven't used aerial raking because you didn't want to use helicopter lift to cut branches, |
| OR | aerial clipping because you didn't want to snuggle the helicopter against treetops and have pitchy branches heaved into the passenger compartment, |
| OR | if you have collected cones aerially but want to increase your collecting rate with the safest aerial cone collecting method now available, |
| THEN | phone Helmut Fandrich for more information about the new patented Fandrich Aerial Shear which has been in operation for three years. And to top it all off, for 1988 the rental rates Fandrich Aerial Shear are the same as for the Fandrich Aerial Cone Rake: a $300 service charge plus $25 per hectolitre of cones collected. |
