Hello and welcome to tbn. now to share my experience . I recently had the chance to test drive one of your RK 55 cab and non cab models and was asking the young salesman about the tier 4 and if it used the canisters. He dissapointed me because He didn't even know what i was talking about. So undeterred and chalking it up to him being young and probably being just stuck selling tractors i came home and visited the RK website. There i entered the following questions Does the RK tractors use a canister or do they just burn off so to say, and i asked the DB levels of the RK55 cab as it seemed very loud when i test drove it and revved to rpm speed at 540. I got a reply back in a couple of hours *NOT FROM THE RK GUY** but from a young lady at the store where i had test drove the tractors. She immediately gave me an answer to the canister question, a short simple YES. Now the other question was answered directly also, but what followed makes me have concerns. The answer to the noise question was the DB level inside the cab is 85 DB at idle and will go up under load, she then also states that if it is a hydrostatic model that will produce a whine and cause even more noise in the cab. Then she States the whine is normal and would be present with either an open station or cab tractor. **Here is what gets me though, she then goes on to state that the hydrostatic whine is why she directs potential customers to buy the shuttle shift versions of this tractor because they are easier to drive???:shocked:
