Customer Questions & Answers

where do you get the replacement line for this trimmer

I would like to buy this trimmer the reviews are great everyone likes it! But if it's a lot of trouble to get the line --- SORRY NO SELL!!
Asked by: Silverdollar84
When I bought my trimmer, I bought Rino-Tuff Heavy Duty replacement line as I knew I would eventually need it. I got it at Home Depot also and today I had to use it for the first time. It is wonderful. It has line cutter on it also and I just cut it to 19" which is what the original line was. Wish I had known this was so much better than what came with the machine. Easy to replace on the machine as well.

do you need to mix the oil and gas or are they separate?

Asked by: MusicMan
DO Not put oil in the gas. The machine is a 4 cyl. and can run on straight gas. The oil is like in a conventional engine and is separate. Check it often and use the right type. 30 weight, 4 cycl oil.

Why the rule of only mowing up to 15 degrees of incline?

Is this a safety issue, or an issue of oil not getting to the engine if the engine is tilted farther than that?
Asked by: Carolyn
Common sense is all. Just trim the face of the slope so you can handle machine easier. Not trim up or down.

Who is the manufacturer of the engine? Honda? Briggs & Stratton? Another?

Asked by: prisoner6
Generic vertical shaft Chinese. Similar at Harbor Freight for $100 or so. Fixed throttle and choke -- starts up immediately, cuts just fine without fussy adjustments. This is a simplified MTD (Mostly-Tin-Device) copy of the DR format. Lighter weight, much easier to handle.

I have a 21 acre property and I bought this mainly to maintain a 200 ft fire line around my home that I wanted bare. The land around my home isn't entirely flat so a tractor isn't the best tool. It was easy to find the tool in the store and a home depot employee helped load it into my truck(Poway employees have been GREAT! My favorite home depot). Once I got it home and out of the box, I started the setup which is EASY. Pull up the handle bars and choose which setting you like, pour the whole container of oil that came with the machine into it, fill with gas and you're set! My only issue is my machine had a handle arm that connects to the machine and the handle itself, damaged sometime during the process getting to home depot. I'll be contacting Cub Cadet to get a new one. I had to bend it into shape with a pair of pliers to get it to thread. Some people complain that it doesn't have an idle option. I don't find that to be an issue. If the line breaks, I don't want to put new line on the machine unless its off. It always starts on one pull when warm, two when cold. I don't see the issue here. With the machine up and running, I got to work. I have your usual tall grass and thick weeds that show up in any ecosystem. The Cub Cadet with the factory line made easy work of these. I could trim nearly infinitely with the factory line on those plants. When it comes to the thick California chaparral, the Cub Cadet does an OK job. It's not the machine's fault because it's not the price of a $2,500 brush mower. Line is not made to cut through 1/2" thick desert shrubs. With that said, I could take down 2 or 3 of those shrubs before needing to replace the line. When I bought my Cub Cadet, I also bought a 100' spool of Rino-Tuff .155 line from home depot. With that line, I could maybe get through one shrub before needing to replace the line. I'll be looking elsewhere for line because home depot, sears and tractor supply co. don't sell tough enough line for me. I was able to clear about 3 acres of thick weeds on varied terrain in around 5 hours. If it was perfectly flat with grass type weeds only, I could had done twice as much. Overall, I'm surprised and impressed with this machine. If it even gives me one season of faithful service, I would had gotten my money out of it. If i paid someone to do the work for me this machine has done for me, it would cost me $1,000 or more. I've only had it for 2 days and my neighbors are so impressed with it, they're asking to borrow it.

I did a lot of research and read the reviews on several retailers that carry the Cub Cadet ST100. Almost all were positive and the negatives, what few they were seemed like operator lack of mechanical knowledge. I used a Ryobi gas weed eater on the front weeds that were a foot or two high in the yard. Man that wasn't fun, changing line and fixing it every 10 minutes if I got that far. Started looking for the walk behind but didn't want to blow a ton on something I'll use once or twice a year. I settled on this and stumbled over a HD online add that had this for $399! Was ready to head to HD to see if the local HD had these in stock. Whoohoo!!! Been in there before at the height of weed season and nobody had anything in stock. Around here everybody has an acre or two and they were buying them like hotcakes. Anyhow pulled this ST100 out of the box, tightened a few nuts, put in oil (provided) and gas and she fired up first pull! I should say first pull with the safety handle depressed. Couldn't understand why the pull didn't pull and had to resort to ready the directions, lol! This is a winner! Was getting dark but had to test it out on an acre of one to two foot weeds, some green and others dry. The motor has one speed and compared to a weed eater didn't seem revved up. That was deceiving as this cut down everything in it's path. Keep in mind on tall green weeds go slow and push in and pull back. Those green stalks will wrap around the spinning line holder and bog it down to a stop. Not the fault of the machine as that thick a matting was a couple of inches thick wrapped around it. Anyhow if it lets me I'll attach a pic. Plus this has a 3 year according to the box.

Was concerned that you can't disengage the spinning head while the engine runs but not an issue because it starts so easily. After assembly I ran it for a couple minutes and stopped it to check the oil level. Noticed the oil was grey on the dip stick. Ran the unit for a couple hours and noticed the oil got darker. Changed the oil and it was black! Note the ST-100 is assembled in China. Ran it for a another hour and the new oil stayed clear. Plenty of power. The push bar/handle is a little thin and bothers my hands. The Sears didn't. Will have to rig up some cushioning.

I have 2 acres of rocky, weedy, uneven property to mow. It works very well, always starts on first or second pull, and is easy to change the sting.

Rated 5 out of 5 by from Monster This is my second season with this machine. I haven't found anything it won't mow down. I mow two acres of scrub brush and weeds. It is great.

Rated 5 out of 5 by from String trimmer mower Let me start by saying my yard is rocky, uneven and a mess. There was no way I could use a lawn mower. I had to use a weed eater to do my entire yard. After running the weed eater for over an hour my hands go numb from the vibration. I decided that I would give the cub cadet string timer mower a shot. I love it, starts right up, can maneuver around the rocks ( can't do with a mower), don't worry about dulling blades and it's easy to push! Changing out the string is very easy! I highly recommend it!

Rated 5 out of 5 by from Great Trimmer Great trimmer for weeds and bush clearing. The only thing I had an issue with was when got it seemed to be slow running speed. After looking it over I found the bracket that connect the governor spring for controlling running speed was bent down not parallel like it should be. I unhooked the spring and straightened out the bracket and after re-hooking the spring it runs a lot better now does not bog down when butting. Still a lot of play in the governor not running at the highest speed it could go to but running a lot better. When you get it I would check for that as mine was bent way down so seed was very low when running.
