Questions & Answers

Q:what engine oil should you use
by|May 7, 2024
1 Answer
Answer This Question

A:  This unit has a Kohler CH440 engine and they recommend All-season Kohler PRO 10W-50 Synthetic Oil as it is specifically formulated to extend the oil change interval to 300 hours. Alternative regular or synthetic 10W-30 engine oils may be used with Kohler engines but require 100-Hour oil change intervals for proper maintenance. Make sure to put in about 1.2qts or towards the top of the dip stick line as this engine has a sensitive low oil shut off which prevents the engine from starting. If you have any questions, feel free to contact us at 1-800-344-3371 or Support@QVTools.com.

          Great performance, excellent value
          I read many negative reviews before purchase but glad I ordered anyway. Very reliably pull starts in 1 or 2 pulls only (I did not want another battery to maintain). You do have to tilt with one arm and pull with the other; if I were using it every week of the year I would go electric start. The hand brake over center adjustment may loosen up from vibration over time; just give it a fresh twist when reapplying the brake. Good design, quality build, great results. No regrets.

            unit was little damaged in shipping and had to be worked on before I could use. but after using it I am happy with performance. busted emergency stop pull start was pushed into side stopping rope to retract and dented gas tank.

            This machine might not be as big as commercial units but it’s mighty and reliable! I had over 40 stumps of various sizes and hiring someone was going to be over $4K. So I bought this machine instead and it has exceeded my expectations and saved me money too!

            I was surprised to how quickly it was delivered! It arrived in A-1 condition and was easy to assemble. I was shocked to how well it performed! Highly recomend!

            Stump grinder rating
            did not get the extra set of cutters with my purchase. The very first thing you should do is replace the 18(pcs.) M10 bolts and nuts with a stronger grade than 8.8. Used mine for 30 seconds and a couple of the bolts broke causing the cutter to fly off and a chip on the tooth. The tires must be inflated every couple of weeks so will eventually get tubes. The Kohler recoil engine starts easy and the throttle cable is heavy duty.
              Works like a charm.
              I started using mine this spring and I’ve done probably 40-50 stumps with many oak stumps. It’s definitely a good investment if you like to do things yourself. The only thing I would recommend is checking the teeth for tightness before you use it. If the machine starts to vibrate you either chipped a tooth or one’s loose or fell off. Also my kill switch doesn’t seem to want to kill it but it’s not a big deal I just use the choke to kill it. It runs great and starts easy every time .

                Awesome Machine!

                Used this 3 times so far on 10 stumps. Stumps have been from 6 inches to 28 inches and the grinder has work as good, if not better, then expected. Would definitely recommend purchasing this if you’re in the market for a stump grinder.
                Better then expected

                Quality of the Power King over all is great
                The machine was easy too. Assemble. Factory needs to tie wrap wires and cables up in box to prevent damage. My wires was chewed up from machine moving around and sitting on it. The Percision break brackets are weak and was bent for the break handle. Made brackets to rebuild what manufacturer needs to do. Never seize packet needs to be added for the main stump grinder handle, the threads on nut handle was Goulding, so added never seize and it was so much easier to tighten and loosen.
