Model Features

  • Reduced-Emission Engine Technology - Caring for Nature
    The STIHL Inc. “Caring for Nature” seal identifies its powered products that are more environmentally conscious, producing zero or low exhaust emissions. STIHL Inc. defines “low exhaust emissions” as being cleaner than EPA and/or CARB exhaust emission standards.

    More information

  • X2 Air Filtration System
    The X2 Air Filtration System revolutionizes the cut-off machine industry by allowing air filters to last up to a year, based on cutting conditions. Outside air enters the system in a swirling motion, removing 80% of dust particles. This pre-cleaned air is then routed through the primary and secondary air filters before being sent into the engine. The X2 Air Filtration System is virtually maintenance free and maintains an incredible 99.96% cleaning efficiency.
  • Anti-Vibration System
    STIHL has developed a system for minimizing the vibration levels of handheld outdoor power equipment. The STIHL anti-vibration system helps reduce operator fatigue and provides a more comfortable working experience.
  • Semi-Automatic Belt Tensioning
    With consistent, semi-automatic re-tensioning, this feature increases the service life of the belts and shaft bearings.
  • Ergonomic Grip
    The ergonomic top-handle bar design provides an optimal comfortable grip in any working position.
  • IntelliCarb™ Compensating Carburetor
    The IntelliCarb™ Compensating Carburetor is designed to automatically adjust the air/fuel ratio when the air filter becomes restricted or partially clogged and maintains the engine’s correct RPM. IntelliCarb™ uses air from the clean side of the air filter to control the diaphragm and flow of fuel. As the air filter becomes dirty and less air is available for the carburetor, the IntelliCarb™ system adjusts the fuel flow to compensate for the decrease in air flow. This is in contrast to typical carburetors that utilize this air from the “dirty” side of the air box.

Reviews

TS 420 STIHL Cutquik® is rated 4.2 out of 5 by 16.
Rated 3 out of 5 by from Adequate We own 6 stihl saws, the 420s have had more issues with dependability and mufflers,than the 700 series. I do not think we will purchase any more 420s in the future.

Rated 2 out of 5 by from More muffler problems Our company has 2 of these saws - the newer one does not have the compression release button so we thought there must be improvements made. One saw has the third new muffler and the other saw has had two. Loctite has not been the answer. They run and saw great when not broken

Rated 5 out of 5 by from Well-made, durable cut-off saw for contractors We buy Stihl products exclusively because we know they will last a long time, and are easily repaired. Our men are not that easy on these things, another reason we go for the durability of Stihl.

Rated 5 out of 5 by from Best saw on the market Best saw for the money. Great power to weight ratio

Rated 5 out of 5 by from Great saw Muffler screws becoming loose all the time, aluminum gasket gets ruined. I do own 5 of them, ALL have same problem, even better tread gets damaged, ripped out from cylinder.(I do retread and put 1mm bigger screw with high heat and vibration resistant tread lock) and think will have to put tread lock on new saw muffler screws before first use.Other ways it's a GREAT saw, compare to TS400(I had around 20) it's holding up really great. All of them still runs, no mechanical breaks like TS400 had with piston rings, axle bearings. We do masonry and it gets its beating dry or wet cutting.

Rated 5 out of 5 by from saws work well we have 8 ts400+7 ts420s i freshen them up in the winter all very good saws.the last one we got does not use a decompression valve! I question that. but i trust stihl.they are the best we can find

Rated 3 out of 5 by from Muffler issues I own a few of these 420 saws, i have had problems with all of them. mufflers come off within a matter of a month or two. I have tried Loctite on the bolts, also had them worked on by stihl dealers and they break off again. I have been using stihl equip for years but am more than likely done buying these cut-off saws if this flaw continues to be a problem.

Rated 5 out of 5 by from Two thumbs up. This is a great tool. We wish we would have bought it years ago. Starts easy, runs great, has lots of power, blades last a long time. We are cutting a lot of 2 7/8 inch pipe and some 4 inch makes quick work of it. If you are thinking about one get one you will not be sorry.

Optional Accessories

  • STIHL ElastoStart™
    The ElastoStart™ starter handle is a feature of STIHL. It is a starting grip with a built-in shock absorber that helps reduce the effort when pulling on the starter cord. The ElastoStart™ starter grip noticeably reduces the sudden peak forces (compression) normally felt during cranking. The forces which occur at the grip after the first compression stroke are smoothed out.
  • STIHL Cutquik® Cart
    Ideal for long, precise cuts, this cart offers improved handling and cutting performance with a forward weight orientation and a toolless quick connect system.
