John Deere JS45


$529.00 Released October, 2008

Product Shot 1 The Pros:Self-powered. Front wheels on casters - easy to maneuver. Side-discharge, mulching or bagging.

The Cons:Caster wheels make for an odd aesthetic. Crankshaft bends EASILY and is NOT covered by warranty. Height adjustment is per individual wheel.

The John Deere JS45 is the top-model walk behind, self driven lawnmower of those offered by John Deere. It is powered by a 4 cycle 190cc Briggs & Stratton engine that has 8.75 lb-ft of gross torque.

Product Shot 2  The Fresh Start fuel tank cap contains fuel stabilizer that drips into the tank to ensure fresh fuel and quick starts at all times and overhead valve design gives more efficient engine operation. The MowMentum Drive System gives you infinite speed adjustments from 0 to 3.6 mph by pivoting the handle control. The 3-in-1 blade provies outstanding cutting performance and is designed to be used with any of the three grass-clipping handling options; side-discharge, mulching or bagging. Unlike other the other mowers in this line, the JS45 has lockable front caster wheels to give this mower a zero-turning-radius. Also unique to this model is individual wheel height adjustements from 1.25" to 4".

It has built in safety features like the zone-start system which requires that the engine be started from behind the handle bar, and the blade is designed to stop when the control handle is released. The wheels themselves are made of high-impact plastic with a molded rubber tread for superior traction and long life. The handlebar has conveniently located controls for easy operation, and can be easily adjusted or folded down for compact storage or transport.

Anonymous: #john_deere_js45 This is a piece of junk. All the pieces are breaking off one by one! Only my second season and the first season it was in the shop as well. John Deere should be ashamed to put this product on the m Jul 1, 11

Booma: #john_deere_js45 The crankshaft bends easily on this mower and isn't covered by the warranty. My lawn doesn't have stalagmites, tree stumps, or anything like that and I've used a cheap Murray lawn mower for years with no problem like a bent crankshaft. Second mowing season with the JD and it's been the shop for over 5 weeks. Newsflash: homeowners with walk-behind mowers are NOT the priority customers at a farm equipment dealer.

There was another js45 there with the exact same problem, a bent crankshaft. If you do a little research on the web, you'll see that it's a pretty common problem. Sounds like a design flaw to me. They should have the engineers from Murray come over and give them some tips LOL! Jul 28, 09

    Anonymous: If you are looking for a good quality product like you would expect from John Deere the JS35 is not the one to buy. Don't have to hit anything very substantial and the crankshaft will bend. Apr 23, 11
