That is similar to the grinder I use. Definatley get the hydrostatic/ self propelled version. There are many makes of similar grinders. Rayco, Powertek, Beeline ( sunrise concepts) . I really like this style of grinder. There is a learning curve but once mastered you will smoke any one using a Vermeer SC252. These grinders accell in ground speed , tight quarters. I can remove a 48" maple in 15 minutes, a 20" stump in 2 minutes and a 10 in stump in 20 seconds. I`ve been using the machine for a few years and I see no need to go bigger. If stumps are bigger than 48" I sub it out. I make most of my bounty doing tree work but owning the grinder lets me offer the whole package and that gets me the bid in most cases.
Fast forward to March 2014
In 7 hours using my Beeline SP-13 and Husky SG-13 we ground 43 pasture stumps yesterday, for us a record production day. The Beeline ran first in class and top breed all day long. The Husky weighs 250 and by the end of the session weighed a ton to pull up the slope and we tack a hill rather than try to pull direct. Today the last 10-12 in this project of 135 stumps will be done. Then we will do oil change and rotate the Green #500 teeth and clean the air filters. This project was guessed at by the customer at 40-50 stumps but we did a measured count the third day of the job progress so we would know what we were in for. The customer is very pleased and we are physically in shape for a lot more work and service to The Lord, for He provides for our every need.
