Front Renovator on Grizzly

 

The original implements I built for the Front Renovator are Here

 

This "Front Renovator" attaches to the plow mount on the front of the Grizzly.  It's raised and lowered using the winch.

 

The front renovator is a simplified version of the front renovator on snow cats.  The idea is to work the snow in front of the Grizzly so the final grooming by the drag on the back of the Grizzly creates a better ski trail.  It's really for the two extremes - deep powder snow or a hard icy trail.

 

When the front renovator is down on the snow, steering can be difficult, so I also added a weight peg on the front.  It can hold two 25 lb weights, and I have a 50 lb cast iron weight I put inside the front cargo box.

The front renovator consists of Push Tubes with a Cross Bar and three implements.  The implements connect to the Cross Bar on the Push Tubes:

  • Triple Cutters

  • Front Ladder

  • Deep Snow Skis

The Triple Cutters have:

  • One row of 1/2" solid steel teeth spaced 3/4" apart on a steel frame with white UHMW plastic with a curved front

  • Two rows of 3" solid steel teeth spaced 2" apart.  These were the original teeth on my Tidd Tech.  I welded them together and bolted them to the small cutters with the UHMW plastic. 

The Triple Cutters are used:

  • In low snow conditions, they renovate the trail when the spring loaded teeth on the Tidd Tech would take a real beating

  • In icy conditions, they renovate the trail before the spring loaded teeth on the Tidd Tech

  • With an inch or less of new snow, the mix the new snow with the old snow before the spring loaded teeth on the Tidd Tech

The Front Ladder is a small version of my Ladder Drag.  In 5"-8" of new snow, it goes thru/under the new snow, mixes it, and takes the air out of the snow.  It also cuts down drifts and smoothes out the trail.

 

The Deep Snow Skis are little skis that attach to the Cross Bar on the Push Tubes.  In deep snow, the skis hold the Push Tubes up and the Cross Bar goes thru/under the new snow, mixes it, and takes the air out of the snow.  It also cuts down drifts and spreads out the snow.  It's for prepping the trail in really deep snow.
